Each square kilometre of Australian sea surface water is contaminated by around 4,000 pieces of tiny plastics, according to our study published today in journal PLOS ONE and data repository Figshare .

These small plastic fragments, mostly less than 5mm across, are loaded with pollutants that can negatively affect several marine species, from tiny fish and zooplankton to large turtles and whales .

Plastic pollution hazards to Australian species and ecological communities are therefore likely broader than those officially recognised .

Understanding the plastic pollution issue

Unfortunately, part of our plastic waste winds up in the oceans. Plastics can be transported from populated areas to the marine environment by rivers, wind, tides, rainwater, storm drains, sewage disposal, and flooding, or can directly reach the sea from boats and offshore installations.

Throughout their marine journey, plastics break down into increasingly smaller pieces mostly due to the effect of sunlight and heat.

These plastic fragments, commonly called microplastics when smaller than 5mm, represent the vast majority of human-made debris present at beaches, seafloor, and in the water column.

The effects of plastics on food webs and ecosystems have become focus of concern over the last decade. It is now known that over half of our plastic objects contain at least one ingredient classified as hazardous .

To make matters worse, plastics that enter the oceans become increasingly toxic by adsorbing oily pollutants on their surface. When plastic is ingested, these concentrated toxins can be delivered to animals and transferred up their food chains.

This biomagnification of toxins is more likely to occur when plastics are small enough to be ingested by low trophic fauna , such as small fish and zooplankton.

These tiny ocean plastics may affect the health of entire food webs, which include humans. For instance, little plastic pieces were found in the stomach of some Southern Bluefin tuna captured off Tasmania and destined for human consumption.

What kind of plastic and where does it come from?

Until now, plastic contamination in Australian waters was mostly inferred from beach clean-up reports. There was no at-sea survey focused on sampling plastic debris in waters around this country.

I wanted to fill this gap. During my PhD research, I went on seven transit voyages aboard three Australian vessels: RV Southern Surveyor , RV Solander , and Comac Enterprise .

During these trips, I used a net called Manta Net to catch floating plastics at the ocean surface.

Small fragments of hard plastic were the most common type, but soft plastics, such as fragments of wrappers, and strings (mostly fishing lines) were also common.

These plastics were mostly made of polyolefins (polyethylene and polypropylene). These polymers account for 52% of our plastic production and are typically used to make throwaway packaging. They are also used for manufacturing fishing equipment such as crates, nets, ropes, and lines.

Our overall mean sea surface plastic concentration was 4,256.4 plastic pieces per km 2 . This mean value is higher than those reported for other regions, such as the Caribbean Sea (1,414 pieces per km 2 ) and Gulf of Maine (1,534 pieces per km 2 ).

However, in the subtropical gyres, plastics tend to accumulate due to converging ocean currents, and mean plastic concentrations are higher: from 20,328 pieces per km 2 in the North Atlantic Gyre , to 334,271 pieces per km 2 in the North Pacific Gyre . The Mediterranean Sea is also a global hotspot for plastics: it has around 116,000 plastics per km 2 .

We observed higher plastic concentrations close to major Australian cities (Sydney, Brisbane) and industrial centres (Karratha) as well as in remote areas where ocean currents converged (such as south-west Tasmania).

These observations, along with our ocean current modelling results, indicate that marine plastics reach Australian waters from multiple sources: domestic and international populated areas, as well as maritime operations.

Plastics, made mostly of oil and gas, are cheaper than the natural materials they replace for the manufacture of many objects, such as packaging and fishing gear.

As a result, incentives to re-use or recycle every-day items have decreased over the last few decades. Meanwhile plastic production has increased from 1,700,00 tonnes in 1950 to 280,000,000 tonnes in 2011 .

In Australia, 1,476,690 tonnes of plastics were used in 2011-2012, of which just 20.5% was recycled . Most of these plastics (around 37%) were used for manufacturing single-use disposable packaging, including plastic bottles, cups, and bags.

Marine plastic pollution is a global issue caused by our massive production of plastic waste. The solution for this recent environmental problem is not simple.

We believe there are three important steps. First, decrease plastic waste: this could be achieved by reducing production of single-use plastic packaging. Second, improve our plastic disposal practices on land at an international level. And last, better enforce the laws prohibiting dumping of plastics at sea.

16 Water Pollution Facts and Statistics in Australia: 2024 Update

• Last updated: Mar 09 2024

Note: This article’s statistics come from third-party sources and do not represent the opinions of this website.

Australia is the sixth largest country in the world in terms of area. They have a wide variety of different environments and ecosystems, including rivers, oceans, lakes, mountains, and deserts. These diverse areas are all connected by the water cycle. The unpopulated arid centers of Australia are connected to the densely urban centers on the coasts, which are, in turn, connected to the oceans themselves. What does all of that mean for Australia’s water pollution? Australia has a good track record when it comes to water pollution but not a perfect one.

Here are sixteen facts and statistics about Australia’s water pollution updated for this year.

The 16 Water Pollution Facts and Statistics for Australia

• Australia manages a marine ecosystem that extends over 13 million square kilometers .
• Australia manages the third largest marine ecosystem in the world , and 85% of Australians live within 100 km of a marine environment.
• Australia has one of the cleanest beaches in the world at Fraser Island Beach.
• Australia also has one of the dirtiest beaches in the world at Port Phillip Bay.
• Australian marine waters are contaminated with roughly 4,000 pieces of plastic per square kilometer .
• Large scale urban expansion has caused widespread pollution in Australia’s southeastern estuaries.
• Marine habitat alteration includes the death of kelp forests, bleaching of coral ecosystems, and increased rates of mortality among the local wildlife.
• The Australian Department of Climate Change, Energy, Environment and Water is working on serious pollution issues such as ballast water, toxic antifoulants, introduced marine pests, pollution from shipping operations, and marine debris.
• Australia has the 25th cleanest drinking water in the world.
• Australia has 144 documented incidents of groundwater contamination
• Australia is very dry, and many inland communities rely heavily on groundwater for drinking water and agricultural water.
• Contaminated water can lead to health issues for citizens.
• Large bushfires can cause groundwater pollution by causing effusive runoff in dry areas.
• Flooding can also contaminate groundwater by washing large amounts of toxins and chemicals into the aquifer.
• Contaminated groundwater can have severe economic impacts , including increased healthcare costs and decreases in agricultural productivity.
• Contaminated groundwater can also damage local ecosystems with polluted runoff and mixing.

Australia General Marine Facts

1. australia manages a marine ecosystem that extends over 13 million square kilometers..

(Earth Reminder)

Australia is a country that doubles as a continent. Australia is entirely surrounded by ocean water, and it is responsible for managing this massive coastline. The shoreline, coastline, islands, and offshore waters all fall under the responsibility of the Australian government to manage and observe. Australia has the seventh longest coastline in the world.

2. Australia manages the third largest marine ecosystem in the world, and 85% of Australians live within 100 km of a marine environment.

Australia’s massive coastline creates the third largest marine ecosystem in the world that is managed by a single country. The size of this marine ecosystem is important because the vast majority of Australians live near the coast. The dry interior of the country is largely unpopulated compared to the coasts. That means that millions of Australians are directly affected by the health of the oceans under Australia’s care.

3. Australia has one of the cleanest beaches in the world at Fraser Island Beach.

(The Travel)

Australia’s coastline is home to one of the cleanest beaches in the world at Fraser Island. Fraser Island is located in northeastern Australia and represents Australia’s water quality at its best. The beaches are immaculate, and the freshwater sources on the island feature some of the cleanest water on Earth. Fraser Island is an example of what Australia is striving to achieve with all of its water sources.

4. Australia also has one of the dirtiest beaches in the world at Port Phillip Bay.

Unfortunately, Australia is also home to one of the dirtiest beaches in the world. The beaches around Port Phillip Bay are particularly vulnerable to pollution. The bay is large, enclosed, and shallow. Those features make it easy for bacteria and pollution to build up and infect nearby beaches. Port Phillip Bay is influenced by pollution from the nearby city of Melbourne.

Australia Marine Pollution Statistics

5. australian marine waters are contaminated with roughly 4,000 pieces of plastic per square kilometer..

(The Conversation)

A recent study examined the particulate matter collected while trawling the surface of Australia’s ocean water and found an abundance of small plastic pieces. Many of the plastic particles were 5 mm or less in diameter. That makes them extremely small. These small pieces of plastic can settle on marine wildlife on the ocean floor, like coral and kelp. It can also be ingested by wildlife causing ill health effects. These plastics are a result of land-based pollution along with economic marine activities like shipping and fishing.

6. Large scale urban expansion has caused widespread pollution in Australia’s southeastern estuaries.

(Frontiers)

One problem spot for Australia’s water pollution has been its southeastern estuaries. These estuaries include mangrove patches, coastal streams, and shallow offshore waters. These estuaries have been degrading in quality over the past few years. Researchers have highlighted the recent population growth and expansion in the region as one of the main culprits of the rise in estuary pollution. Construction and home waste can cause contaminated runoff to infect the shallow estuary waters.

7. Marine habitat alteration includes the death of kelp forests, bleaching of coral ecosystems, and increased rates of mortality among the local wildlife.

The increased pollution in these estuaries and other offshore habitats has caused severe alterations to the natural environment. As pollution increases, it causes the health of the ecosystem to diminish. Pollution kills kelp, small mammals, fish, and coral. As these living things die prematurely, it affects the cycle of life that has naturally been occurring in these areas for thousands, if not millions, of years.  This can cause a negative feedback loop that can tank the health of an ecosystem for years and can cause irreparable damage.

8. The Australian Department of Climate Change, Energy, Environment, and Water is working on serious pollution issues such as ballast water, toxic antifoulants, introduced marine pests, pollution from shipping operations, and marine debris.

(The Australian Department of Climate Change, Energy, Environment)

In order to tackle these problems, the Australian Department of Climate Change, Energy, Environment, and Water is working with multiple international agencies to decrease rates of marine pollution. Some of the things they’re working on decreasing include antifoulants which are chemicals used to clean the bottom of boats and ships. They are attempting to reduce the rate of invasive marine pests invading local ecosystems and increasing the mortality rate of native species. They are also working on tackling marine debris, like the microplastics that have been found in Australia’s waters.

Australia Groundwater Pollution Statistics

9. australia has the 25th best water quality in the world..

(World Population Review)

Australia has the 25th highest water quality in the world. That puts it in the 88th percentile worldwide for quality drinking water. Australia ranks ahead of countries like the United States, New Zealand, and Portugal. Australia trails countries like Canada, Belgium, and the United Kingdom in terms of overall water quality.

10. Australia has 144 documented incidents of groundwater contamination incidents.

(Groundwater pollution in Australian regional aquifers)

Australia has had its fair share of groundwater contamination incidents. These incidents have had stark local effects, but the larger incidents have contaminated entire regions. Groundwater contamination largely comes from agricultural runoff and industrial waste. Australia has a large mining economy, and mining causes a lot of groundwater pollution due to heavy metal runoff.

11. Australia is very dry, and many inland communities rely heavily on groundwater for drinking water and agricultural water.

(Department of Health and Aged Care)

Certain regions of Australia, especially arid and inland regions, are particularly vulnerable to groundwater pollution. Since Australia is so dry, many communities rely heavily on groundwater for their needs. Many rural Australians tap into the aquifer for drinking water, livestock water, and crop water. That makes all of these things vulnerable to polluted groundwater.

12. Contaminated water can lead to health issues for citizens, including (but not limited to) cancer, intestinal issues, and cardiovascular problems.

The effects of contaminated groundwater can be severe. Prolonged exposure to dirty or contaminated drinking water can lead to cancer, gut problems, and heart issues. That means that the health of many Australians is directly linked to the health of their drinking water. That makes drinking water health and safety extremely important for the population and the economy.

13. Large bushfires can cause groundwater pollution by causing effusive runoff in dry areas.

Brush fires are causing an increase in groundwater contamination. Brush fires cause large streams of muddy soot to flow into the aquifer. These streams can contain dead animals, chemicals from the local soil, and increased amounts of particulate matter. All of that will eventually make its way into the groundwater after a fire. Brush fires are also becoming larger and more frequent, according to the Australian government.

14. Flooding can also contaminate groundwater by washing large amounts of toxins and chemicals into the aquifer.

Flooding is also causing an increase in groundwater contamination. Like brushfires, flooding causes large amounts of runoff that pick up toxins and pollutants. Flooding in urban areas causes higher rates of pollution than flooding in rural areas. Flooding can take waste, garbage, oil, and chemicals from roadways and carry them into the groundwater system. Australia has been racked by serious flooding in 2022, and this flooding is causing an increased rate of groundwater pollution. The final severity and damage from the 2022 floods in Australia have yet to be determined since it is an ongoing event.

15. Contaminated groundwater can have severe economic impacts, including increased healthcare costs and decreases in agricultural productivity.

(Geosciences Australia)

These increased rates of groundwater pollution can have a large economic effect on the local population. Dirty groundwater can lead to dirty drinking water, which can lead to adverse health effects. Poor health puts a larger strain on hospitals, insurance companies, and worker productivity. Contaminated groundwater can also affect agricultural areas as dirty water hinders plant growth and can sicken livestock. All of that adds up to money taken out of the economy.

16. Contaminated groundwater can also damage local ecosystems with polluted runoff and mixing.

Unfortunately, groundwater runoff can also hurt local water sources. Dirty groundwater ends up in rivers, streams, and lakes. That water can then flow to the sea and contaminate shallow estuaries, like the ones ailing in southeastern Australia. The pollutants in groundwater runoff will then start to affect other freshwater sources over time if the problem is not addressed.

Frequently Asked Questions

Does australia have clean water.

Australia does have relatively clean water. Australia has the 25th cleanest drinking water in the world, which is in the 88th percentile. However, Australia does have room for improvement. In terms of overall water quality, Australia has some problem spots, like any developed nation, but the water is safe to drink, and they do not have any ongoing health emergencies connected to poor drinking water. Australia is suffering from increased groundwater contamination from recent natural disasters and estuary degradation due to increased urban development.

Is Australia a Major Ocean Polluter?

No. Australia is not a major source of ocean pollution. Many nations to Australia’s north, including India, China, and Indonesia, are some of the world’s worst ocean polluters. The plastics being put into the oceans to Australia’s north break down and are carried to other parts of the world on ocean currents. That pollution affects Australia’s waters, but Australia is not the main culprit of ocean plastic contamination, especially nearby ocean plastic contamination.

This passive ocean pollution from nearby nations is one of the reasons that Australia’s government is working diligently with international agencies to try and curb local and international ocean pollution.

Is Water Pollution in Australia Going to Get Better or Worse in the Near Future?

The outlook on Australia’s water pollution is mixed. On the one hand, there are determined efforts underway by the government to study and curb current water pollution in and around Australia. On the other hand, Australia is suffering from increased rates of flooding and brush fires. According to the Australian government, these increases are due to the effects of climate change, and those are not going to decrease in the near future. If Australia continues to be subjected to large-scale cyclical flooding and large brush fires, it will struggle to get a hold of the groundwater pollution issues.

It is impossible to stop or prevent massive flooding or brush fires, so Australia’s hands are tied in those respects. Instead, they will have to work on understanding and mitigating the effects of these natural disasters on their groundwater supply and adapt accordingly.

Australia has a good track record when it comes to water pollution but not a great one. It has room to improve the quality of its drinking water. It also continues to battle ocean pollution coming in from other major world polluters that are infecting its massive marine ecosystem. But Australia is aware of the issues they are facing and are taking steps to study and mitigate the problems to the best of its ability.

5 biggest challenges facing Australian water

World Water Day is a day we can focus our attention on the importance of water and some of the challenges faced managing Australian water catchments and supply. Water is a key driver of economic and social development, it also has a basic function in maintaining the integrity of the natural environment.

We caught up with our Hydrology and Catchment Management experts; Associate Professor Willem Vervoort , Associate Professor Thomas Bishop  and Dr Floris Van Ogtrop , from the  Sydney Institute of Agriculture  and  School of Life and Environmental Sciences ; and asked them what they thought were the 5 biggest challenges facing Australian water. Here is what they had to say:

1. Australia has the global highest variability in climate and streamflow

Australia has complex variations in rainfall patterns in time and space arising from the combination of the geographic structure and the dual effects of Indian and Pacific Ocean. Due to Australia having the global highest  variability in climate and streamflow  water management systems would benefit the most from weather forecasting. Forecasting in such variable conditions is very difficult and  knowledge about future rainfall  is important for agriculture management and planning in arid and semi-arid regions.

2. Water data is still very sparse west of the ranges or away from the coast

Despite all our efforts and investment,  data is still very sparse west of the ranges  or away from the coast, which makes forecasting and management difficult. We are working on novel solutions to integrate satellite data to fill the gaps. Australia is up there with US and Europe in public (water) data accessibility, we are big proponents of open data and increased data access.  Data driven models  are helping discover new developments in predicting water availability and quality.

3. Murray Darling Basin management has no easy solutions

The Murray Darling Basin management is very complex, there are no easy solutions. This means all solutions are negotiated in a high uncertainty environment. "Collaboration and communication between the different states and the people is the only way forward, as none of the solutions for the  Murray Darling Basin plan  are easy, and all will result in pain for some part of the community. But this also means, that the best solutions can only be achieved by negotiation, not by walking away from the process," said Associate Professor Vervoort.

4. Climate change may increase the occurrence of toxic cyanobacteria blooms

Climate change resulting in increasing temperatures and associated increased rainfall intensity will increase the occurrence and risk of eutrophication. Eutrophication is when a body of water becomes overly enriched with minerals and nutrients that induce excessive growth of plants and algae. The factors triggering cyanobacteria bloom formation are found to be especially complex. Recent PhD graduate Liz Symes, investigated the proliferation of  undesirable cyanobacteria within eutrophic freshwaters  which is now reported on a global scale.

5. Foodborne illness may be linked to source waters used for irrigation of fresh produce

Australian health authorities have confirmed the sixth person has died of listeriosis as a result of consuming contaminated rockmelons. Listeria is a bacteria that can be found in the environment including water sources. This highlights the importance of increasing our understanding of contamination in water potentially used for irrigating fresh produce. Our PhD candidate, Emily White, is currently profiling and monitoring  microbial populations in agricultural water . Her research will investigate environmental conditions that influence contamination risk in source waters.

Metrics details

Sustainable management of the natural environment is essential. Continued environmental degradation will lead to worsened health outcomes in countries and across generations. The Sustainable Development Goals (SDGs) provide a framework for viewing the preservation of natural environments and the promotion of health, well-being and health equity as interconnected pursuits. Within the SDG framework the goals of promoting environmental sustainability and human health are unified through attention to the social determinants of health and health equity (SDH/HE). This paper presents findings from a document analysis of all Australian environment sector policies and selected legislation to examine whether and how current approaches support progress toward achieving SDG goals on water, climate change, and marine ecosystems (Goals 6, 13 and 14), and to consider implications for health and health equity.

Consideration of a broad range of SDH/HE was evident in the analysed documents. Related collaborations between environment and health sectors were identified, but the bulk of proposed actions on SDH/HE were initiated by the environment sector as part of its core business. Strengths of Australian policy in regard to SDGs 6, 13 and 14 are reflected in recognition of the effects of climate change, a strong cohesive approach to marine park protection, and recognition of the need to protect existing water and sanitation systems from future threats. However, climate change strategies focus predominately on resilience, adaptation and heat related health effects, rather than on more comprehensive mitigation policies. The findings emphasise the importance of strengthened cross-sectoral action to address both the drivers and effects of environmental degradation. A lack of policy coherence between jurisdictions was also evident in several areas, compounded by inadequate national guidance, where vague strategies and non-specific devolution of responsibilities are likely to compromise coordination and accountability.

Conclusions

Evidence on planetary health recognises the interconnectedness of environmental and human health and, as such, suggests that ineffective management of climate change and water pose serious risks to both the natural environment and human well-being. To address these risks more effectively, and to achieve the SDGs, our findings indicate that cross-jurisdiction policy coherence and national coordination must be improved. In addition, more action to address global inequities is required, along with more comprehensive approaches to climate change mitigation.

Human well-being is dependent upon the health of the planet. Sustainable management of the natural environment is essential to support the health and health equity of individuals and communities, and is, therefore, a necessary focus for public health efforts.

Australia currently ranks highly in terms of environmental performance globally [ 1 ]. However the Australia: State of the Environment 2016 reports emphasised that if current environmental trends continue, the Australian natural environment will have deteriorated significantly by 2050 [ 2 ]. The main pressures on the Australian environment are resulting from climate change, unsustainable land use and habitat degradation [ 2 ]. Australia is one of the world’s most resource and carbon intensive countries, contributing to depletion of finite resources and climate change [ 1 ]. The detrimental effects of climate change in Australia (including rising temperatures, fluctuating climates, and rainfall changes) are becoming increasingly evident, as is a reduction in groundwater quality [ 3 ]. Biodiversity across ecosystems is also poor and worsening [ 1 , 3 ]. Recently Australia has experienced increased drought, a decline in the numbers of pollinators, and more regular extreme storms, which undermine food production [ 2 ]. Some crops are also becoming less nutritious due to atmospheric and soil changes [ 4 ]. Rising sea levels, ongoing demand for coastal land and severe weather events increase pressure on coasts [ 3 , 5 ]. Pollution in Australian oceans is increasing, and climate change is warming and acidifying ocean waters, compromising marine ecosystem stability and diversity [ 6 ]. All of these trends also threaten human well-being, particularly by increasing the risk of natural disasters and detrimental climate changes, while potentially reducing access to clean air, safe drinking water and adequate food resources [ 2 ]. Such threats may lead to increased chronic and acute disease, particularly type 2 diabetes, obesity and overweight as well as cancers, heart disease and cardiovascular diseases, and reduced life expectancy [ 2 ]. With natural systems currently being degraded to an extent that is unprecedented in human history, both in Australia and around the world [ 7 ], there is an immediate need for action.

The United Nations’ 2030 Agenda for Sustainable Development [ 8 ] views the preservation of natural environments and the promotion of human well-being and health equity as interconnected pursuits. The Agenda consists of 17 Sustainable Development Goals (SDGs) and 169 targets that countries across the world have committed to achieve by 2030. Achieving the goals requires countries to strike a balance in integrating social, economic and environmental pursuits. Recognition of human rights underpins the agenda, requiring partnerships between sectoral areas to ensure a standard of living for all that is adequate to sustain well-being. One of the SDGs, Goal 3, focuses explicitly on human health. However, all SDGs are interconnected, and almost all goals have some connection to the systems that influence human well-being and health equity- including governance of the natural environment [ 9 , 10 ]. Recognising the interconnections between SDGs is imperative to mobilise resources for responsible environmental stewardship that will also protect human well-being [ 9 , 11 ].

Our research critically examined Australian governments’ environment sector policies and the extent to which they do or do not address social determinants of health and health equity (SDH/HE). In this paper we draw on findings from the research to: a) examine whether and how the goals, objectives, strategies and values expressed in Australian environment sector policy and legislation documents will support action toward achieving three SDGs: 6, 13 and 14 (see Table  1 ); and b) consider the implications of such actions (or inaction) for health and health equity. The three SDGs have been selected because they are directly related to the core business of government environment departments. However, it is recognised in our research and in World Health Organisation documents on the SDGs, including the Global Action Plan: Healthy Lives and Well-being for All 2019 [ 12 ], that environmental goals (and all goals) in the SDGs have clear links to the social determinants that influence human health, well-being and equity.

The analysis that is presented in this paper applies a planetary health perspective. Planetary health recognises that human health is inseparable from the broader environments and ecosystems in which individuals and communities live [ 7 , 13 ]. This idea stems from the traditional knowledges that have been passed on within Indigenous cultures since time immemorial [ 14 ]. Planetary health views health not merely as absence of disease, but as a state of complete wellness at all levels- local, national and global [ 14 ]. In 2015 the Commission on Planetary Health offered the following definition:

the achievement of the highest attainable standard of health, wellbeing, and equity worldwide through judicious attention to the human systems—political, economic, and social—that shape the future of humanity and the Earth’s natural systems that define the safe environmental limits within which humanity can flourish. Put simply, planetary health is the health of human civilisation and the state of the natural systems on which it depends. [7, 1921].

This perspective situates human health within the context of the human made systems that are used to manage the environment. In doing so, it shifts environmental health risks, such as climate change and pollution, from being abstract forces to risks that can be understood, monitored, managed and mitigated by humans to realise positive change [ 7 ]. This dimension of planetary health justifies and encourages policy analysis as a research method because policy shapes how humans use and govern environmental resources. A planetary health perspective also asserts that humans live within a narrow “safe operating space of planetary existence” [7: 1921]. If the boundaries of that space are pushed too far, the conditions that currently sustain human well-being will be stretched beyond breaking point. This provides impetus for seeking policy change that will reduce risks to human health to fulfil an intergenerational responsibility to protect environmental systems, and allow future generations to thrive [ 7 ]. When it comes to protecting the natural environment, governments hold a lot of power and responsibility to act on behalf of the current and future generations. They exercise these through legislation but also through policies which guide action towards broader societal aims. This study analyses the policy landscape in Australia.

Interwoven throughout our policy analysis are references to neoliberalism. Miller and Orchard [ 15 ] discuss neoliberalism as an ideology that shapes public policy in Australia. Neoliberalism is based on the assumptions that sustained economic growth will have benefits that trickle down to benefit all people, and that free markets are most effective at achieving economic growth [ 15 ]. Neoliberalism also emphasises the importance of minimal state intervention in economic and social affairs [ 15 ], privileging individuals and businesses as entrepreneurial agents in generating capital and new markets. Miller and Orchard [ 15 ] argue that the neoliberal values that shape Australian policy often conflict with social democratic values, such as equity and social justice. Neoliberal politics in Australia has been characterised by the use of state institutions and resources to promote and/or protect private interests. Neoliberal ideas and values have also been used to justify the absence of strong policies on environmental protection by instead privileging narrow economic goals and pursuits. Where relevant, the concept of neoliberalism is drawn upon in this paper to illuminate some of the values that inform the policies, and that operate to shape the policy directions analysed in this paper.

The research informing this paper examined how the policies of Australian governments in the natural environment sector influence population health, well-being and health equity [ 16 ]. It was based on a document analysis of strategic policy documents from environment departments in the state/territory governments and the national government of Australia (current at September 2016). Legislative Acts were also selected where they covered an area not addressed by strategic policy. Policies and legislation documents were selected for analysis because they guide the work of government decision makers as they determine which actions will be implemented and prioritised.

Document sample

To identify the strategic policies and Acts, websites of relevant government departments in each Australian jurisdiction were searched between March and September 2016. A department was deemed relevant if it produced policy on any topic related to environmental protection or natural resource management. A list of relevant strategic policies and Acts was compiled from the website of each department. Documents were considered relevant if they were listed on the department websites at the time of the document search and appeared to still be active (i.e. not archived or superseded). Legislation was selected only if it covered areas of departmental policy that were not addressed by strategic policy from that department. The lists of policies and legislation were checked with public servants in each department to ensure currency and completeness. When additional strategic policies and legislation were suggested by public servants, these were added to the lists.

The final sample consisted of 178 strategic policies and Acts. All these documents were analysed using a coding framework that links the problem framing, values, goals, evidence, objectives and strategies stated within the documents with the various aspects of social determinants of health and health equity (SDH/HE) (see Table  2 ).

Document analysis

Qualitative document analysis was employed to create a systematic procedure for reviewing and evaluating the structure, content and implications of the documents. Qualitative document analysis requires interpretation of data to elicit meaning and develop understanding about what is present and not present in the documents, and to what effect [ 20 ].

Each strategic policy and Act was entered into NVivo 11 and read at least twice. The first read was relatively superficial, aiding researcher familiarity. This was followed by a second reading which involved closer interpretation, with a focus on coding the content according to pre-defined categories (see Table 2 ). The framing of each strategic policy and Act was examined and the goals, objectives, strategies, and values articulated throughout were assessed to determine how and whether they aligned with the intent of progressing health, well-being and equity. Explicit mentions of words associated with health did not need to appear for segments of text to be coded. Instead, text interpreted as relevant to SDH/HE was also coded, guided by the list in Table 2 .

The researchers identified silences within the strategic policies and Acts, where no aspect of the content could be coded into a particular category. Silences were also identified when the framing and goals of a particular document were inconsistent with its stated objectives and strategies, leaving some aspects relevant to health under-addressed or ignored within the proposed actions.

Peer-checking of the analysis occurred during regular team meetings between all authors, which involved collaborative re-coding and interpretation of policy segments. The implications of policy directions for population health, well-being and health equity were discussed during the meetings, as was the influence of ideology in shaping responses to environmental problems [ 21 ]. The final stage of the analysis involved checking the emerging findings against the SDG action areas to determine the extent of congruence, and identify areas where further action is required in Australian policy.

This section begins with an overview of the main topics and SDH/HE that were addressed within the analysed documents. This is followed by a more focussed presentation of key themes that emerged during the analysis relevant to SDGs 6, 13 and 14.

Australian environment policies address a broad range of topics and social determinants

The analysed documents address an extensive list of topics (see Table  3 ) clearly related to SDH/HE and indirectly or directly related to SDGs 6, 13 and 14.

Multiple links to the SDH/HE were identified in the documents during discussion of these topics, with some links made explicitly and deliberately. Analysis of the goals, objectives and strategies that surround explicit discussion of health within the documents suggests that drawing links between environment sector business and the promotion of population health assists environment departments to establish the importance of their work within the broader agendas of governments. This was particularly apparent in Victoria and South Australia with strong emphasis on the co-benefits produced by ‘ Healthy Parks, Healthy People’ initiatives:

Healthy Parks Healthy People is encapsulated in four key principles: • the wellbeing of all societies depends on healthy ecosystems. • parks nurture healthy ecosystems. • contact with nature is essential for improving emotional, physical. and spiritual health and wellbeing. • parks are fundamental to economic growth. (Parks Victoria Shaping Our Future, page 4)

Climate change was also frequently linked to well-being both explicitly and implicitly, and to a potential decline in future well-being. In most instances an explicit focus on the well-being of vulnerable groups was evident:

… climate change will have direct and indirect impacts on our health and wellbeing, particularly for vulnerable members of the community such as the elderly, those who live in remote settlements, the sick and people on low incomes. Health and community services will be affected across the state. (SA Prospering in a Changing Climate, page 8).

Most often though relationships between the SDH/HE and environment sector business were implied rather than explicit. The SDH/HE coded most frequently in the data were: built environment, climate change, education, employment, land or Country connection, open space and transport. For example, discussion of employment was prominent in policies from all jurisdictions, especially in regard to the potential benefit of “ Supporting and promoting the employment of Aboriginal staff within natural resource management” (NSW Fisheries Strategy and Implementation Plan, page 3). Fears about employment loss as a result of industry transition to cleaner fuels were directly countered by strategies to support increased employment in the renewable energy industry. Similarly, use of more ecologically sustainable waste technologies was advocated on the basis of employment generation:

… there is often a lost employment and economic opportunity in disposing resources to landfill instead of reusing them. The Government will review the Tasmanian Waste and Resource Management Strategy to incorporate actions (Embracing the climate challenge Tasmania’s climate change action plan, page 33).

During the analysis it became clear that countering such fears was one of the primary means through which the creators of the documents justified shifts in government policy away from practices that may support economic development, but damage the environment. Carefully balancing priorities appeared essential to garner support for new initiatives, because justifications based solely on the intrinsic value of environmental conservation may not have been sufficiently well aligned with governments’ neoliberalist economic agendas.

Strong emphasis on preserving safe water and sanitation, but fragmented approach

Ensuring effective management of water and sanitation in all countries is imperative to realise SDG 6, and support health [ 22 ]. In general Australian drinking water and sanitation standards are high; however, the analysis identified several pressures on the sustainability of reliable, affordable and safe service provision. These include population growth, climate change and ageing infrastructure. Governance of drinking water and sanitation systems in Australia is also complicated by the diversity of systems that exist in different jurisdictions:

Local government or local government businesses mostly provide drinking water and sewerage services, while the Queensland Government provides some bulk water supplies. While diverse in ownership, the sector also ranges in size and capacity. The largest service providers in South East Queensland service a population of more than one million people, while very small service providers serve some of the world’s most remote areas in the arid west and wet tropical north. Regardless of size and geography, every service provider needs to deliver services when, where and how they are needed by their local community. (WaterQ: a 30-year strategy for Queensland’s water sector, page 7).

Under the Australian Constitution the states/territories have ultimate responsibility for managing water resources. However, the Commonwealth government also plays a role in developing national strategies because many of the pressures facing water and sanitation supply in each jurisdiction stem from nation-wide issues. Document analysis revealed that governments in all jurisdictions recognise that strengthened, coordinated action is required to ensure a clean sustainable drinking water supply. However, the findings also suggested that current systems are at odds with this because regulatory, governance and pricing mechanisms vary greatly across jurisdictions. Furthermore, the increasing privatisation of services has resulted in a loss of some direct control by governments, further complicating governance of water and sanitation, and management of their human-health impacts.

Much of the discussion in the analysed documents pertained to water and sanitation systems in urban areas. Less attention was directed to rural and remote locations where standards are often below that of urban areas due to poorer infrastructure, remoteness and more extreme climate conditions [ 23 ]. The documents remained almost completely silent on actions to address the greater expense and lack of reliability of services in very remote parts of Australia, which disproportionately affects Aboriginal and Torres Strait Australians, further reinforcing existing social and health inequities [ 24 ].

Drought, rising salinity and rainfall changes are future threats that were discussed in the documents as more likely in Australia as a result of climate change. These factors were identified in all jurisdictions as having the potential to compromise the future quality of Australian drinking water supplies, demanding innovative solutions:

Extreme drought in the Murray-Darling Basin and the Mt Lofty Ranges has meant we can no longer use water as we have in the past – we need to be more efficient and much wiser when using our most precious resource … In future, our water supplies will feature climate-independent water through desalination. This ensures a portion of our water needs is guaranteed, despite increasing climate variability expected in future. (SA Water for Good Plan, foreword).

While climate change is an ever-present threat to water systems, the extent to which effective and innovative action will eventuate to mitigate climate change is questionable. Thus, our analysis suggests that fragmented governance of water and lack of action on climate change are key risks to Australia’s capacity to contribute to SDG 6 and ensure universal access to safe water supply, which as water is a determinant of health will also undermine achievement of SDG 3 (Achieving good health and well-being).

Climate change: considerable attention, but selective focus

In regard to SDG 13, all jurisdictions besides Queensland had policy/ies dedicated to action on climate change ( n  = 10). Furthermore, the need for action on climate change was expressed in nearly all documents ( n  = 124 of 178), even where the documents were primarily focussed on other topics. In the initial problem framing sections of the documents a broad array of climate change causes and impacts were identified:

Our climate is warming at an unprecedented rate, largely as a result of human activity, and is already 1 °C higher than it was 100 years ago … The atmosphere and oceans have warmed, the amounts of snow and ice have diminished, and sea levels have risen. These changes are having, and will have, widespread impacts on human and natural systems. (ACT Climate Change Adaptation Strategy, page 8).

Much of the explicit discussion about climate change-related health impacts was on the implications of rising temperatures and heatwaves, including more frequent heat-related illnesses and an increased prevalence of vector-borne diseases. Drought was also discussed frequently, with farming communities identified specifically as a vulnerable population. Less direct pathways between climate change and determinants of human health were mentioned only sporadically across the documents. Such pathways include climate change-related psychological stress contributing to mental ill-health and health risks from more frequent or severe weather-related events, including floods, bushfire, and storms [ 4 ]. The links between climate change and increased risks for social dislocation resulting from rising sea levels in Australia and neighbouring island countries were seldom discussed. Similarly the potential for climate change to contribute to food insecurity due to water insecurity and soil quality depletion was rarely mentioned [ 4 ]. Thus we found considerable attention to climate change in Australian policy, but generally inadequate examination of the complex relationships between climate change and social determinants of health.

In addition, the analysis indicated that far greater emphasis was placed on outlining climate change risks, rather than coherent, meaningful plans for action. To illustrate this trend, data on the topic of ocean acidification (relevant to SDG 14) will now be examined.

Acidification of oceans: problem statements with few progressive mitigation strategies

Ocean acidification was identified as a concern in 17 of the documents. It was consistently linked to climate change, and explained as resulting from increased atmospheric concentrations of carbon dioxide. Acidification is problematic, particularly because it disrupts growth within marine ecosystems and impedes oceanic uptake of atmospheric carbon dioxide, potentially exacerbating climate change [ 25 ]. These environmental effects have major implications for food security and climate change as SDH/HE. Despite recognition of the risks associated with acidification, and understanding of the mechanisms by which it occurs, the inclusion of strategies for action was inconsistent, with few direct actions proposed in most of the 17 documents, and responsibility deferred to other areas of sectoral/government activity.

Where strategies for action were outlined, these were usually superficial and/or a continuation of actions that have already been implemented for a significant period, despite acidification continuing to increase since those actions commenced. An example comes from the Australian Government Reef 2050 Long-Term Sustainability Plan , which establishes clear relationships between acidification, climate change and environmental decline, suggesting dire consequences:

The biggest long-term threat to coral reefs worldwide is climate change and the Great Barrier Reef is no exception. Damage to reefs as a consequence of climate change comes from ocean acidification, sea temperature increases, altered weather patterns (such as more intense storms) and rising sea levels. (page 22). Future predictions indicate sea level rises and temperature increases will continue, the pH of the ocean will gradually decline and weather will be more severe. (page 10).

The few strategies outlined to address ocean acidification in the Plan include repeated water sampling to provide “ Reef managers with information on where, when and how ocean acidification is affecting the Reef ” (page 61), and continued “ constructive participation in the United Nations Framework Convention on Climate Change (UNFCCC) and its Kyoto Protocol; through practical cooperation with regional partner countries; and through supporting developing countries to take actions that reduce emissions” (page 61). The Government also committed to a modest objective of reducing emissions to “ five per cent below 2000 levels by the year 2020 ” (page 61) (that is over a period of 5 years as the Plan was released in 2015). If that reduction were achieved it would represent a 19% decrease in emissions from the levels previously projected for 2020, rather than an actual decrease of 19%. As such, these strategies do not match the magnitude nor urgency of the problem of acidification that is conveyed in the problem framing statements, and their likely effectiveness in tackling further acidification, and health implications of this, is doubtful.

Resilience rather than risk mitigation: emphasis on capacity to respond to climate change

Further exacerbating concerns about the likelihood of future effectiveness in tackling climate change is an overemphasis within the documents on achieving climate change resilience . This emphasis directs attention towards strategies such as vulnerability assessments, risk identification and management, and activities to adapt to changing climates:

We will continue to build resilience to a changing climate within our natural environment and in relation to our Aboriginal and historical heritage values for future generations through: • ongoing development and implementation of tools to support decision-making including assessing climate impacts; • ongoing key research and monitoring programs; and. • regulatory activity and collaboration with stakeholders. As our understanding of actual and projected climate impacts increases we will adapt our approach accordingly. (Embracing the climate challenge Tasmania’s climate change action plan, page 16).

While Queensland did not have a dedicated climate change policy at the time of data collection, a focus on achieving climate change resilience was replicated consistently throughout policies on other topics:

This strategy will incorporate measures which contribute to the resilience of the Great Barrier Reef. In addition … A number of local governments are already preparing coastal hazard management plans and other initiatives in response to the anticipated effects of climate change. (Reef 2050 Long-Term Sustainability Plan, page 23).

A focus on resilience can contribute to actions on SDH factors such as urban form or food security to moderate health impacts of climate change. However, our findings suggest that a focus on resilience is far more dominant than strategies to mitigate climate change. This is concerning as it may limit Australia governments’ capacity to contribute to SDG 13 and channel resources away from the more difficult – but essential – task of preventing the major, multiple risks to human health that climate change presents.

Strong leadership on marine parks, but subordinance to mining interests

Consistent with SDG 14, Australia performs strongly in designating marine parks to provide for long term protection and conservation of particular ocean sites. Currently, marine parks exist in all Australian states and territories with coastal borders, covering 3.3 million square kilometres or 36% of Australia’s oceans [ 26 ]. Strict legislation was identified, with national and state/territory Acts that govern and restrict use of marine parks. All state/territory Acts indicate that they are coordinated through national legislation. This is demonstrated by a relatively cohesive approach to marine park management across Australia. Protection of marine parks can make a positive contribution to determinants of health and equity such as Indigenous people’s connection to country, the health of natural environments and food security.

Despite these strengths, analysis of the marine park Acts suggests another concerning theme: the subordinance of environmental conservation to commercial interests, particularly mining interests. A prime example is from the Western Australian Conservation and Land Management Act 1984 (page 8), which states:

nothing in this Act shall derogate from the operation of the Mining Act 1978, the Offshore Minerals Act 2003, the Petroleum and Geothermal Energy Resources Act 1967, the Petroleum (Submerged Lands) Act 1982, (or) any other Act relating to minerals or petroleum .

Such allowances have the potential to reduce Australia’s capacity to meet SDG 14 and to protect the contribution of marine parks to health.

Marine ecosystem preservation: strong understanding of the problems but reactive actions

SDG 14 advocates sustainable use of oceans to manage and mitigate the threats associated with marine pollution, resource depletion and climate change. Action is essential to prevent further pressure on marine ecosystems and the health risks related to determinants such as compromised food security, loss of employment (e.g. tourist industry), and psychological stress from damage to revered ecosystems such as the Great Barrier Reef [ 27 ].

Our analysis reflects clear recognition of the wide variety of threats to marine environments, and the mechanisms causing these threats. Threats stem from increasing coastal development and pollution of coastal waters. The policies emphasised that pollution is driven particularly by fresh-water run-off from stormwater and agricultural lands. This run-off typically contains elevated levels of sediments, pollutants and nutrients, which may slow the growth of seagrasses and other species, while promoting the growth of invasive pest species. However, strategies within the documents focus primarily on reactive actions to counter problems after they have already eventuated.

One driver for the reactive approach is that there is little evidence in the policies of meaningful intersectoral strategising between environment and agricultural departments. Within the policies discussion of the agricultural sector focusses primarily on outlining how climate change will threaten future food production, and on monitoring environmental contaminant levels in food. Furthermore, the need to preserve the health and flow of rivers to service irrigated agriculture is a key driver for three Commonwealth Government policies. The apparent lack of collaboration to change detrimental agricultural practices, limits the power of environment departments to address the root causes of current problems, instead focusing attention on efforts to manage their effects.

Furthermore, it is acknowledged that continuing degradation of coastal ecosystems will exacerbate, and be exacerbated by, climate change. However, coastal protection strategies are largely administered separately from climate change action plans.

Thus there are several ways in which the potential for Australia environment sector polices to contribute to SDG 14 and protect the role of marine ecosystems in health appears to be limited by lack of coordination between relevant areas of policy.

Balancing the human economic value of fisheries with ecosystem conservation

Preventing over-fishing is a key area of action in all jurisdictions and is fundamental to SDG 14, and also a significant factor affecting food security and health of natural environments as determinants of health. All 16 dedicated fishing related policies and Acts covered a range of issues (such as management of fish stock numbers in freshwater and ocean waterways, monitoring long term trends, development of local fisheries management plans, catch limits and fishing licenses). The documents reflected relatively consistent goals, emphasising a need to balance the interests of commercial and private fishers with ecological conservation and fish stock sustainability.

Despite some overall consistency, considerable differences were evident between jurisdictions, driven by the application of different values, about which interests should be prioritised. For example environment sector plans in the geographically small and landlocked Australian Capital Territory (ACT) referred to three primary water uses: Conservation, Water Supply, and Drainage and Open Space . Within each of these categories, a number of secondary uses were permitted provided that they were generally compatible with the primary uses. Such secondary uses included recreation (fishing, boating, swimming). Positioning fishing as a secondary use makes it less important than conservation of waterway ecosystems and biodiversity. It is important to note though because the ACT is landlocked its policies do not govern ocean fishing.

The strong emphasis on conservation in the ACT contrasts to varying extents with the value placed on preserving opportunities for fishing, economic gain and production in other jurisdictions. Although environmental sustainability is still a theme in these jurisdictions, the main focus is on sustaining environmental assets so that these can continue to be used. Fish stocks and associated ecosystems are valued primarily for the purposes of economic development, and to sustain the perceived “right” of individuals and commercial operators to fish for personal consumption or business pursuits:

The Northern Territory’s fish stocks and aquatic habitats will be managed to maintain a quality recreational fishing experience for current and future generations. (Northern Territory Recreational Fishing Development Plan 2012–2022, page 4).

Again, across the data set, few references to fishing practices, or strategies to control these, were included in climate change policies. This was surprising given the strong links between warming oceans, severe weather events, declines in fish numbers and degradation of waterways [ 28 ]. To contribute to SDG 14 and protect fisheries as important contributors to food security, Australian governments should prefer the approach of the ACT, to prioritise protection of the aquatic ecosystems that underpin sustainable fisheries.

Sporadic leadership detracts from a comprehensive national approach

Our findings indicate that weak national leadership may stifle progress towards SDGs 6, 13 and 14 and weaken environment policy action on SDH/HE. The extent to which national policy documents provide meaningful and effective national leadership is unclear for three reasons.

The Australian Government is directly responsible for few actions within national environment policies. Furthermore, most often Australian Government responsibility is contained to very specific tasks that are unlikely to prompt broad scale change, or to demonstrate leadership, for example:

Audit of existing waste infrastructure and local capability in selected remote Indigenous communities as part of essential services audit under the National Indigenous Housing Partnership. (National Waste Policy, page 15)

Responsibility for implementation in the national policies is largely devolved to state, territory and local governments. However, this generally occurs in a vague and non-specific way. For example, it is made clear that the national policies serve to “guide” or “advise” the work of other governments, or to suggest “what can we do”, rather than designating clear responsibility or accountability for action. Furthermore, in the implementation plans attached to the national policies, specific governments are usually not identified. Responsibility is most often devolved generically to “State and Territory Governments” or “All Governments”. Responsibility is also sometimes assigned to generic groups of non-government stakeholders as in the example below:

(National Biodiversity Conservation Strategy, page 57)

One exception to the generally generic attribution of responsibility is where specific natural resources are discussed, such as the Great Barrier Reef, and more specific jurisdictional designations of responsibility are made.

The wording used in the national policies is vague and left open to interpretation. Use of vague language may limit the power of the national strategies in stimulating meaningful action:

development of appropriate management and, if required, disposal strategies where appropriate … .

Continued government encouragement of best practice waste management and resource recovery for construction and demolition projects. (National Waste Policy, emphasis added)

Doubtful policy translation to action due to relative lack of evaluation and monitoring

Overall, the researchers struggled to identify detailed, consistent plans for ongoing evaluation and monitoring of policy implementation across all policies in any of the jurisdictions. Most of the policies did not explain how progress would be monitored or whether there were budgets allocated to facilitate implementation. This is likely to impede the ability of Australian governments to accurately monitor progress in addressing environmental threats to health, and in achieving SDGs 6, 13 and 14.

Australian policy has several strengths in regard to progressing SDGs 6, 13 and 14 and, simultaneously, this means action is being taken to protect and promote human health by addressing social determinants of health. However, there are weaknesses that must be addressed. Through the lens of planetary health, current themes within Australian policy will now be examined under each of the three SDGs to consider the relevant environmental and human health implications, as well as some of the socio-political dimensions of current problems. As explained earlier, presenting a forward-looking approach to understand and shift the current nexus between environmental problems and human health impacts is a core component of a planetary health lens. As such, this discussion will consider strategies for policy improvement.

SDG 6: ensure availability and sustainable management of water and sanitation for all

While Australia currently has relatively high quality drinking water and sanitation systems, the water related threats to human health presented by continued environmental degradation and worsened climate change are concerning. Such threats include restricted availability of adequate, clean river flows, food insecurity and potential increases in floods and the resulting social dislocation. A planetary health perspective stresses the importance of optimising governance systems [ 14 ]. The findings highlight a need across jurisdictions for a more cohesive, coordinated national approach to preserve water and sanitation standards and offset threats. Australian governments already invest in a coordinated approach, developed and administered through the Council of Australian Governments. Under the framework of the National Water Initiative, successive governments across Australia have also been working on a water reform agenda, which has the scope to improve coordination. To protect Australia’s water supply and sanitation as determinants of health it is imperative that this type of work continue, and be sustained over the long term , resisting the damaging impacts of short-sighted political visions and jurisdictional power battles that have impeded past reform efforts [ 29 ]. Furthermore, given that the research findings show continued fragmentation in water system management across the country, work must also be undertaken to examine why this is, and how broader adoption of consistent approaches can be facilitated to optimise use of the resources being invested in the national approach. Water reform work must also address the inequalities in secure water access that have emerged between rural and metropolitan systems to ensure that the SDG aspiration of water and sanitation for all can be realised [ 23 ], and that policies on water do not exacerbate existing health inequities between city and country regions in Australia. This is particularly important to support the well-being and health equity of Aboriginal and Torres Strait Islander people living in very remote country areas.

To build greater sustainability in Australia’s water supply, reform efforts must also acknowledge and challenge existing vested interests. A planetary health perspective encourages deep analysis of environmental management systems to consider how power manifests in ways that may compromise effective environmental management and human health improvements. The agriculture industry is a prime example of a powerful player. On average, agriculture uses 50–70% of the water consumed in Australia each year [ 30 ]. This is problematic, especially given that Australia’s water consumption per person is amongst the highest in the world, despite being the driest inhabited continent [ 31 ]. Large water withdrawals are damaging to rivers and thus likely over time to undermine the important roles that rivers have in supporting determinants of health such as food security, relationship to Country, and the health of natural environments.

Currently, the way that water is governed in Australia is not optimal. Siloed divisions of accountability and action direct responsibility for water system management to the environment sector while many of the levers for change remain unaddressed in other sectors. The relative silence on policy strategies to reduce the water consumption of the agricultural industry reflects siloed structures, but also the role of broader neoliberal government ideologies that privilege economic productivity in shaping policy responses. Many of the changes humans have made to freshwater rivers, such as diversions, and to land, such as clearing and deforestation, have occurred to support agricultural activities and other human resource production [ 31 ]. The majority of Australia’s surface water resources are also still used to service irrigated agriculture [ 31 ]. The amount of water used in agricultural production means that current, unsustainable production activities are likely to have much more impact than domestic water use. Furthermore, Australian cities only recently started to pay attention to adopting the principles of water sensitive urban design and have a long way to go before these aspirations become good practices [ 32 ]. This means that while the environment sector can impose water restrictions on private consumers and encourage water saving measures in the areas it controls, its power to conserve water remains limited. To achieve a truly sustainable approach to preserving Australia’s water resources, and protecting access to secure, affordable safe water as a determinants of health, it is, therefore, imperative that stronger synergies be achieved across environment, agricultural and urban planning policies [ 9 ].

SDG 13: take urgent action to combat climate change and its impacts

Some understanding of the population health impacts of climate change on human well-being is evident in environment sector policies and so, to a degree, this reflects a planetary health perspective. Recognition of such relationships is an important step in progressing towards SDG 13. However there are areas of climate action where improvements are vital.

While Australian environment policies reflect understanding of the causes of climate change, the predominant focus remains on strategies to build community and system resilience to adapt to and accommodate these changes. It must be acknowledged that Australian mitigation strategies, in and of themselves, can have only a small impact on reducing the global greenhouse gas emissions that drive climate change. However, it is vital that all governments act to mitigate climate change, otherwise a tragedy of the commons will result. The tragedy of the commons is a situation in a shared-resources system, such as the global natural environment, where individual users act independently in pursuit of their own self-interests contrary to the common good to deplete the shared resources that all users depend on [ 33 ]. As such, a focus on resilience in Australian policy is important, but will be futile in protecting human well-being in Australia or globally without concurrent, strong action to mitigate climate change [ 34 ].

The findings of this study suggest that both the siloed organisation of policy and the strong economic focus of governments limit the power of the environment sector to deliver mitigation strategies. Given that decision making in all departments influences climate change, and that climate change is an increasingly influential determinant of human health globally [ 35 ], it does not make sense for action on climate change to be regarded only or primarily as environment sector business. Instead it should be positioned as whole-of-government business, with mandated and genuine collaboration across all sectors to halt environmental degradation and reduce greenhouse gas emissions [ 9 ]. Such a whole-of-government approach can be overseen by a central agency, with particular actions delegated to specific agencies across governments. This approach also offers the potential for more effective integration of a social determinants of health lens across policy areas.

Achieving a whole-of-government approach to climate change will necessitate clear and consistent articulation of the links between climate change and the broader agendas (particularly the economic imperatives) of neoliberal governments [ 34 ]. It will also involve utilising the collaborative intent of the SDG framework as a basis for building innovative and strong partnerships between governments, civil society and willing private sector partners, who can work together to use relevant technologies and build capacity [ 9 , 36 ].

The public health sector of governments could assist by mobilising a planetary health agenda and re-orientating understandings of climate change as an ‘environmental issue’ to understanding of it as a whole-of society issue with major implications for human health [ 30 ]. This could be best done by offering effective, realistic and sustainable solutions for combating global warming, and supporting these with evidence and argument about the value of such measures for health and health equity. Focussing only on problems without also providing feasible strategies for effective change may be counterproductive by representing current environmental problems as bleak and unresolvable [ 34 ] and by underestimating the role Australia can play within this global agenda. Furthermore, the potential for whole-of-society benefit should be articulated, emphasising how human well-being and equity for all can be optimised through effective and well-coordinated mitigation action [ 9 ].

Another issue raised by the research is that currently climate change problem framings and resilience strategies direct disproportionate emphasis to populations living in vulnerable circumstances. Such emphasis is justified to an extent. People in vulnerable circumstances, such as low income earners and Indigenous peoples, are already more likely to experience ill-health and reduced life expectancy in Australia and around the world [ 4 ]. Climate change will worsen living conditions, and disproportionally affect those without good access to supportive systems and infrastructure, further compounding disadvantage [ 4 ]. Furthermore, there are groups for whom climate change effects will be particularly devastating; this includes farmers who suffer greatly during drought, flood and extreme temperatures as well as people living near the coast, whose homes may become inhabitable as a result of rising sea levels. However, the current emphasis on groups living in particular circumstances in policy encourages the perception that impacts will be largely restricted to these groups. This is not true as climate change will affect health and well-being across all population groups [ 34 ]. Therefore, those seeking to influence the debate about climate change and health must emphasise its broad impact, further appealing to the need for action from all sectors. Given the power of economics in influencing governance models, quantifying the likely costs of inaction in all sectors, and contrasting these costs with the enormous public health dividends of more effective reduction in greenhouse gas emissions and natural-resource management could offer an effective strategy [ 34 ].

SDG 14: conserve and sustainably use the oceans, seas and marine resources for sustainable development

A strength of current Australian policy is ongoing commitment to the preservation of protected areas, including marine parks. Evidence on planetary health indicates that maintaining protected areas is essential to preserve biodiversity within marine ecosystems, increase fish numbers and support employment in strong nature based tourism industries [ 37 ]. However, outside of protected areas, current management approaches are concerning.

Policy and legislative control of fishing and ocean use in Australia is fragmented. Australia is already experiencing dwindling populations of some fish species that are caught for consumption and sale [ 6 ]. This is affecting the ecological balance of marine environments. On a global scale, similar problems exist, evidenced by a consistent decline in overall fish stocks and biodiversity during at least the past three decades [ 38 ]. This suggests that the predominant neoliberal values expressed in Australian ocean fishing policies, which prioritise economic interests and a perceived right to fishing over conservation [ 13 ], outside of designated marine parks are not supporting progress towards SDG 14, and may undermine sustainable fisheries contribution to food security as a determinant of health. Our findings suggest a need for stronger national leadership in this area, similar to that provided when marine parks were established, in order to offer strict controls over fisheries. Controls should aim to preserve existing stocks, and prevent further declines. A nationally coordinated approach to governing fishing would need to include multiple sectors, and to incorporate actions to protect natural resources from unfettered commercial interests. A more integrated approach is essential since fish populations are strongly influenced by the overall health of marine ecosystems, and these are currently threatened by various human activities apart from fishing [ 6 , 26 ].

Fish should also be managed as part of the ecosystems in which they live, rather than being treated in isolation. An ecosystem-based approach goes beyond static catch quotas and involves continuous and responsive management to ensure that ecosystems can respond to climate change threats, and that all components of marine environments can be supported to flourish [ 28 ]. SDG 14 advocates for an expansion of research and monitoring to support conservation of marine environments. While regular monitoring is currently supported and resourced in many relevant areas of environmental management, such as monitoring of ocean acidification, this generally does not result in the monitoring of all components of an ecosystem in a way that recognises their intrinsic interconnections. Furthermore, resourced commitment to monitoring and evaluating the success of Australia’s own policy actions appears weak. More evaluation will show whether current policy action in Australia is proving effective in offsetting environmental risks before they translate into worsened human health, and create irreparable, widespread degradation of the environmental systems upon which human life relies.

A planetary health perspective also positions Australia’s responsibility to develop effective marine ecosystem management within a global context. The SDG framework highlights the interconnected nature of decisions made in countries around the world, emphasising shared accountability for positive change. Recognising the global health and health equity implications that will result from poor management of marine ecosystems and climate change mitigation highlights Australia’s obligation to address these issues effectively as a responsible global citizen. For example, food security as a determinants of health in many low-latitude low income nations is dependent on seafood [ 39 ]. Over the past three decades though, the worst declines in fish stocks have been in lower-latitude, low income nations [ 39 ]. Continued ocean warming is likely to drive remaining fish and shellfish species from low to high latitudes, potentially reducing fish catch even further in these regions, and globally by up to 30% by 2050 [ 25 , 28 ]. Reductions in water oxygen levels and ocean warming mean that fish are also likely to get smaller in size, and coral reefs (essential for fish breeding and tourism) will be further degraded [ 28 ]. The implications of these trends are likely to hit low and middle income countries hardest [ 4 ]. Wealthy nations like Australia have compensated for declining fish stocks through intensive aquaculture production, by importing seafood from low and middle income nations at relatively low cost and by developing vitamin supplements [ 39 ]. Low income countries have fewer alternatives to make up for the shortfalls in population access to dietary nutrients, however, particularly as increased exports from these countries to wealthier nations are depleting fish stocks [ 39 ]. Imported fish and vitamin supplements are usually expensive, limiting access for those living in low income nations. As a result, communities are often forced to rely on what they can source locally and, increasingly, on less-nutritious processed foods [ 39 ]. We argue that high income countries, such as Australia, have an obligation to preserve their own local resources, to limit the export demand on low and middle income nations, and to take proactive action to reduce their impact on global marine ecosystems to prevent a worsening of global health inequities – now and in the future.

Limitations of this study

This study conducted a census of all relevant policy documents and selected legislation to generate a comprehensive view of the environment policy landscape in all Australian jurisdictions. However, this approach has some limitations. To ensure a census of policy documents, data collection had to be bounded by set time periods. This meant that new documents could not be analysed as they were released or as policy directions changed. In addition, while the content of policy documents and legislation have a strong influence on the implementation activities of governments, these are not the only documents that influence government activity, and in some instances only parts of policies and legislation will be implemented by governments. As such, a more comprehensive understanding of government intent in the environment sector could be derived from also studying implementation activity and budget allocations. However, this was outside the scope of the current project. The authors also acknowledge that further insights into the topic of this paper could be gleaned from studying policies from all government sectors to determine what actions are being taken in all policy portfolios. The broader research from which this paper is drawn focussed on policies from four sectors (environment, justice, urban planning and energy), and also considered whole-of-government strategies (such as strategic plans) where these included goals related to the sectors of interest. However, government actions beyond this were not examined during the research. Furthermore, the design of the study did not allow direct evaluation of the population well-being impacts of policy interventions, instead links between the content of the documents and population health and equity were theorised by the researchers using existing literature and theoretical perspectives.

The social determinants of health and the SDGs are intimately connected [ 12 ]. This paper has presented an analysis of the strengths and weaknesses of Australian environment sector policy in the pursuit of SDGs 6, 13 and 14, and in addressing social determinants of health to protect and promote human health equitably. We identified some strengths, including recognition of the importance of acting on climate change, the strict control of designated conservation areas and recognition of the need to preserve water and sanitation systems in the context of future threats.

However, a lack of comprehensive frameworks to address all drivers of climate change, and weaknesses in the management of waterways and marine ecosystems, still pose serious risks to the future of the natural environment and human well-being. While it is clear that promising policy directions are being pursued in several jurisdictions of Australia, current environmental risks are being compounded by weak national leadership. To address these risks more effectively, and to achieve the SDGs, our findings indicate that policy coherence across sectors and national coordination must be improved. In particular, a more comprehensive intersectoral approach to climate change mitigation is essential, which must acknowledge the interconnections between all elements of ecosystems, and be supported by cost-benefit analyses. An emphasis on the risks of climate change must also be accompanied by practical strategies for change, emphasising how climate change mitigation can improve quality of life for all.

Action to restore biodiversity and prevent further degradation will require major long term reinvestments to reverse environmental deterioration. This will necessitate political commitment to a vision of a sustainable and health-enhancing natural environment. Planetary ill-health is in part a product of the neoliberal ideology that dominates policy in Australia. This ideology creates policies that emphasise short-term economic interests, at the expense of protection for the natural environment. Shifting this focus and respecting the interconnectedness of human well-being and the natural environment is essential to progress the cohesive social agenda that underpins the SDGs, and, ultimately, will be vital to sustain human life on Planet Earth.

Failing Rains and Thirsty Cities: Australia’s Growing Water Problem

Australia is a country on the brink of a water crisis. Understanding why water is scarce and where the water goes will be crucial to keeping Australia’s taps flowing as its population grows.

A koala bear lounges in a eucalyptus tree, lazily chewing leaves in a scene as Australian as one can imagine. But then the koala does something unusual: it climbs down the tree to drink water from a pool. Normally, koalas get nearly all their water from their food, and researchers have linked this new behavior to climate change. Australia is getting hotter and drier, the eucalyptus leaves are less succulent, and now koalas need to drink extra water to survive. It’s a change that seems to reflect a growing awareness among Australians that they need to be more proactive about securing their fresh water.

Straddling the Tropic of Capricorn, Australia’s climate ranges from a tropical north to a temperate south but the vast bulk of its three million square miles is hot and dry. Central Australia’s immense ‘outback’ is made up of semi-arid bush and deserts where temperatures can soar above 50°centigrade and it might not rain for years. This makes Australia the world’s driest inhabited continent—and it’s getting drier. Its average annual rainfall is around 470mm a year, well below the global average, and predictions linked to climate change suggest this could halve again in coming decades. What rain that does fall varies greatly from year to year and is concentrated along the north and east coasts: while most of Australia receives as little as 600mm of rain each year, half the country gets less than 300mm.

2018 was particularly dry, 11% below the recorded mean for 1961-1990 at under 413mm. However, across the continent, Australia’s rainfall is exceptionally varied and individual states felt the effects to different degrees. While Tasmania retained its very wet average with 1,389mm of rain, and Western Australia actually had 10% more rain than usual, other states suffered. The Northern Territory received 7% below average rainfall and Queensland 15% below average; Victoria was 26% below its mean rainfall and South Australia was 24% below with an average rainfall of just 171mm. But it was New South Wales that was among the hardest hit, with its average annual rainfall down 40% on the mean, bringing a devastating drought and severe restrictions across the state.

Australia’s exceptional aridity is the result of a unique combination of factors. Cold ocean currents off the west coast means there is little evaporation to form rainclouds, while the Great Dividing Range that runs down Australia’s east coast prevents rain from penetrating far inland. There are few mountains to force air upwards where it can cool into rain, and the region is dominated by the subtropical high-pressure belt that both warms and dries the air. What’s more, the continent is extremely susceptible to the El Niño–Southern Oscillation, a heating or cooling of the Pacific Ocean that can bring prolonged periods of high temperatures and drought.

Here's what made Hurricane Katrina one of the worst storms in U.S. history

From 1996 to 2010 the Millennium Drought scorched much of southern Australia. Its effects were acutely felt in the agricultural heartland of the Murray-Darling basin and in the densely populated southeast and southwest. Major cities including Perth, Adelaide, Canberra, Sydney, Brisbane, and even Tasmania’s famously wet state capital of Hobart, experienced serious water shortages—Melbourne’s water storage dropped to 33%. But more rain isn’t always the answer. Australia’s floods can be equally extreme with tropical cyclones and storms bringing intense bursts of rainfall that overwhelm drainage systems and cause devastating damage. This January, a monsoon strengthened by a low-pressure system flooded Townsville in Queensland with 1.4 meters of rain in two weeks—twice as much as London gets in a year.

YEAR-LONG ADVENTURE for every explorer on your list

Human activity has made matters worse. Widespread deforestation has intensified flooding while also increasing the salinity of the soil so that the water flowing through it becomes brackish—unchecked this could damage millions of hectares of agricultural land. The overgrazing of sheep and cattle, key economic exports, has been a major factor in desertification with vegetation loss leading to a loss of usable water. Until recently farmers were allowed to draw unchecked amounts of water from rivers causing silting, salination, and fierce disputes between competing users. Similarly, groundwater sources such as aquifers have been used up faster than they can be naturally replenished, especially in the arid interior, so that they are now having to be actively refilled with treated wastewater.

Such restorative schemes could prove crucial as Australia’s demand for water rises rapidly. Already one of the world’s thirstiest countries, per capita water consumption averages 100,000 liters per person and the next thirty years will see its population boom by a further 40%. This is important because Australians consume 340 liters of water per person per day. Of this, outdoor use is particularly heavy, accounting for nearly half of household consumption through car washing, hosing driveways, and using garden sprinklers at around 1,000 liters per hour. While many Australians are increasingly water aware, Sydney has cut its average daily use by 200 liters per person since 1990, further water savings will be vital to minimize future water stress.

A key factor will be Australia’s unusual population concentration with 80% living in a few large coastal conurbations. This brings the potential for significant water efficiencies through integrated infrastructure ranging from wastewater recycling to huge desalination plants. However, move away from the coastal cities and access to fresh water becomes more problematic. Many rural households rely on rainwater or bore water which is often tainted by its high mineral content. These local supplies are dwindling and increasingly need to be supplemented by purchasing tankers of freshwater or, where finances allow, laying pipelines for long-distance water transfer schemes to sustain larger towns.

Farming remains by far the biggest drain on Australia’s water supply at nearly 70% of the water footprint. Half of Australia’s agricultural profits comes from irrigated farming which is concentrated in the Murray-Darling Basin. Here, extensive over-extraction forced government intervention during the Millennium Drought with severe water restrictions that saw cotton production quartered, meat production halved, and rice farming stopped almost entirely. This has led to much tighter regulations and ongoing investment in more efficient irrigation schemes. Meanwhile, although industry only uses 16% of Australia’s water footprint, water-heavy industries such as mining are on the rise, especially in the arid interior.

For now, Australia may have sufficient freshwater to meet its needs but the unreliability of its rainfall, the uncertainty of climate change, and the difficulties of supplying fast-growing cities and isolated rural communities poses problems. With river flows expected to drop by 10- 25% within ten years, pressure on Australia’ water systems will grow as demand from population rises. To ensure its water security Australia must continue to adapt—people, as well as koalas, will need to change their behaviors to get the water they need.

102 Water Pollution Essay Topic Ideas & Examples

Water pollution essays are an excellent way to demonstrate your awareness of the topic and your position on the solutions to the issue. To help you ease the writing process, we prepared some tips, essay topics, and research questions about water pollution.

🌎 Air and Water pollution: Essay Writing Tips

🏆 best water pollution essay topics & examples, 📌 remarkable air and water pollution research topics, 👍 good research topics about water pollution, ❓ research questions about water pollution.

Water’s ready availability in many locations makes it an easy choice for a variety of purposes, from cleaning to manufacturing to nuclear reactor cooling. However, many companies will then dump water, now mixed with waste, back into rivers or lakes without adequate cleaning, leading to significant environmental pollution.

However, there are other types of harm, such as noise pollution, which are less obvious but also dangerous to sea life. It is critical that you understand what you should and should not do during your writing process.

The stance that big manufacturing industries are the sole culprits of the damage done to the world’s rivers and oceans is a popular one. However, do not neglect the effects of other water pollution essay topics such as microorganisms.

Microbes can spread dangerous illnesses, making them a danger for both water inhabitants and the people who then use that water. Furthermore, they can eat up oxygen if left unchecked, starving fish and other water organisms and eventually making them die out.

Such situations usually result from agricultural practices, which can lead to powerful nutrients entering the water and enabling algae and other microorganisms to grow excessively. An overly lively environment can be as harmful as one where everything is threatened.

With that said, industrial manufacturers deserve much of the attention and blame they receive from various communities. Construction of dedicated waste-cleaning facilities is usually possible, but companies avoid doing so because the process will increase their costs.

You should advocate for green practices, but be mindful of the potential impact of a significant price increase on the global economy. Also, be sure to mention more exotic pollution variations in your types of water pollution essay.

Provide examples of noise pollution or suspended matter pollution to expand on the topic of the complexity of the harm humanity causes to the ecosphere.

You should show your understanding that there are many causes, and we should work on addressing all of them, a notion you should repeat in your water pollution essay conclusions.

However, you should try to avoid being sidetracked too much and focus on the titles of pollution and its immediate causes.

If you stretch far enough, you may connect the matter to topics such as the status of a woman in Islam. However, doing so contributes little to nothing to your point and deviates from the topic of ecology into social and religious studies.

Leave the search for connections to dedicated researchers and concentrate on discussing the major causes that are known nowadays. By doing this, you will be able to create an excellent and powerful work that will demonstrate your understanding of the topic.

Here are some tips for your writing:

• Be sure to discuss the different types of pollution that is caused by the same source separately. Surface and groundwater pollution are different in their effects and deserve separate discussions.
• Focus on the issues and not on solutions, as an essay does not provide enough space to discuss the latter in detail.
• Be sure to discuss the effects of pollution on people and other land inhabitants as well as on water creatures.

Essay on Water Pollution in 200 Words

Water is plentiful on Earth, present both above and beneath its surface. A variety of water bodies, such as rivers, ponds, seas, and oceans, can be found on the planet’s surface. Despite Earth’s ability to naturally replenish its water, we are gradually depleting and mishandling this abundant resource. 

Although water covers 71% of the Earth’s surface and land constitutes the remaining 29%, the rapid expansion of water pollution is impacting both marine life and humans. 

Contaminants 

Water pollution stems significantly from city sewage and industrial waste discharge. Indirect sources of water pollution include contaminants that reach water supplies via soil, groundwater systems, and precipitation. 

Chemical pollutants pose a greater challenge in terms of removal compared to visible impurities, which can be filtered out through physical cleaning. The addition of chemicals alters water’s properties, rendering it unsafe and potentially lethal for consumption.

Solution 

Prioritizing water infrastructure enhancement is vital for sustainable water management, with a focus on water efficiency and conservation. 

Furthermore, rainwater harvesting and reuse serve as effective strategies to curb water pollution. Reclaimed wastewater and collected rainwater alleviate stress on groundwater and other natural water sources. 

Groundwater recharge, which transfers water from surface sources to groundwater, is a well-known approach to mitigate water scarcity. These measures collectively contribute to safeguarding the planet’s water resources for present and future generations.

Essay on Water Pollution in 500 Words

The term “water pollution” is employed when human or natural factors lead to contamination of bodies of water, such as rivers, lakes, and oceans. Responsible management is now imperative to address this significant environmental concern. The primary sources of water contamination are human-related activities like urbanization, industrialization, deforestation, improper waste disposal, and the establishment of landfills.

Reasons for Water Pollution

The availability of freshwater on our planet is limited, and pollution only increases this scarcity. Every year, a substantial amount of fresh water is lost due to industrial and various other types of pollution. Pollutants encompass visible waste items of varying sizes as well as intangible, hazardous, and lethal compounds.

Numerous factories are situated in proximity to water bodies, utilizing freshwater to transport their waste. This industrial waste carries inherent toxicity, jeopardizing the well-being of both plant and animal life. Individuals living close to polluted water sources frequently suffer from skin problems, respiratory ailments, and occasionally even life-threatening health conditions.

Water contamination is also intensified by urban waste and sewage, adding to the problem. Each household generates considerable waste annually, including plastic, chemicals, wood, and other materials. Inadequate waste disposal methods result in this refusal to infiltrate aquatic ecosystems like rivers, lakes, and streams, leading to pollution.

Methods of Water Pollution Management

Raising awareness about the causes and consequences of water pollution is crucial in significantly reducing its prevalence. Encouraging community or organizational clean-up initiatives on a weekly or monthly basis plays a pivotal role. 

To eradicate water contamination completely, stringent legislation needs to be formulated and diligently enforced. Rigorous oversight would promote accountability, potentially deterring individuals and groups from polluting. Each individual should recognize the impact of their daily actions and take steps to contribute to a better world for generations to come.

Real-Life Encounter

My affection for my town has always been heightened by its abundant lakes, rivers, and forests. During one of my walks alongside the river that flowed through my village, I was struck by the unusual hues swirling within the water. The once-familiar crystal-clear blue had been replaced by a murky brown shade, accompanied by a potent, unpleasant odour. Intrigued, I decided to investigate further, descending to the riverbank for a closer look at the source of the peculiar colours and smells. Upon closer inspection, I observed peculiar foam bubbles floating on the water’s surface.

Suddenly, a commotion behind me caught my attention, and I turned to witness a group of people hastening toward the river. Their frantic shouts and vigorous gestures conveyed their panic, prompting me to realize that a grave situation was unfolding. As the group reached the river, they were confronted with the distressing sight of numerous lifeless fish floating on the water’s surface. 

Following a comprehensive investigation, it was revealed that a local factory had been releasing toxic chemicals into the river, resulting in extensive pollution and the devastation of the ecosystem. This investigation left me stunned and disheartened, acknowledging the significant effort required to restore the river to its own form.

Essay About Water Pollution Water is basic to life requirements and more than 70% of the earth’s surface is cover by water. W.H.Auden said that “thousands have lived without love, not one without water”. Water is one of our most valuable and important resources because all living organisms require water to survive their life. The human body consists of more than 50% of water, so it proves that humans can survive without food but cannot survive if without water. Fish and other living organisms need water which forms lakes, rivers and oceans as their shelter. Water pollution caused by when humans started discarding sewage and toxic chemical into the ocean, effluents from industries, manufacturing and agro-based industries, dumping, oil pollution, acid rain and so on. Sewage that causes water pollution is one of the most important problem in the earth today. Rivers contaminated by sewerage contain high levels of organic pollutants, and they become breeding grounds for harmful bacteria and viruses that may cause fish and other aquatic organisms impossible to survive and become extinct. Sewage also causes many diseases such as cholera and typhoid that will detrimental to humans. For a few more times, water has been infected with sewage and human cannot enjoy clean water. Recently, the Amazon rainforest had some of the highest deforestations in the world, which has hugely affected the access to and quality of water. This causes the area of the earth to lose a lot of freshwater due to this problem. This is heartbreaking and terrifying to think that the Amazon is the largest rainforest on the planet which creates 20% of the earth’s oxygen, basically is the “lungs of the world”. People are literally destroying the miracle of home and waste a lot of water to put out the fire. Through deforestation, trees are being removed, naturally, there is a loss of support on the soil and leads to more loss of soil. Thereby causing higher rates of soil erosion that seeps into the nearby lakes, affecting the water quality of the lake. It also makes it impossible for sea creatures to survive because of the lack of clean water and the collapsed soil that fills the river’s space, the creatures cannot multiply. In Malaysia, the environmental problem that becoming more serious from time to time is water pollution. This pollution occurs when pollutants are not treated properly to remove harmful compounds are discharged into water bodies. So it is very important to prevent polluting of water bodies and remove existing contaminants or reducing the concentration of these contaminants and use it as desired. Dealing with water pollution is something that everyone including the government and local people need to get involved with. The ways of treating polluted water are industrial wastewater treatment which the raw sewage is needed to be treated carefully and correctly in a water treatment plant before it can be released into the environment. Therefore, all manufacturing industries should assure they have a well-designed treatment facility that can prevent water pollution. Besides, we should never throw rubbish away anyhow. If the rubbish bin is none around, we can take the rubbish home and put it in the rubbish bin. These include places like beaches, riverside and water bodies. We must use water wisely and do not keep the water pipe running when not in use. It can significantly prevent water shortages and reduce the amount of dirty water that needs treatment plants. Anti-pollution laws and regulations must be applied to everyone because it always played an important role to ensure water pollution are kept to the minimum. Anti-pollution laws can as well establish measures that put restrictions for water pollution. These laws are usually directed to industries, hospitals, schools and market areas on how to dispose of, treat and manage sewage.

Water Pollution and How it Harms the Environment

Global pollution is a problem. Pollution can spread to remote areas where no one lives, despite the fact that urban areas are typically more polluted than the countryside. Air pollution, water pollution, and land pollution are the three main categories of pollution. Some contaminated water has a terrible smell, a muddy appearance, and floating trash. Some contaminated water appears clean, but it contains dangerous substances that you can't see or smell.

Together, developed and developing nations must fight to conserve the environment for present and future generations. Today, we dig deep into the subject of Water Pollution. This article can be an introduction to water pollution for kids as we will read many things such as the causes of water pollution further in the article.

What is Water Pollution?

Water contamination occurs when pollutants pollute water sources and make the water unfit for use in drinking, cooking, cleaning, swimming, and other activities. Chemicals, garbage, bacteria, and parasites are examples of pollutants. Water is eventually damaged by all types of pollution. Lakes and oceans become contaminated by air pollution. Land contamination may contaminate an underground stream, a river, and ultimately the ocean. As a result, trash thrown on an empty lot can eventually contaminate a water source.

Water Pollution

The water cycle, called  the hydrological cycle, involves the following steps:

Evaporation- Because of the sun's heat, the water bodies such as oceans, lakes, seas etc., get heated up, and water evaporates in the air, forming water vapours.

Transpiration- Like evaporation, the plants and trees also lose water from them which goes to the atmosphere. This process is called transpiration.

Condensation- As the water evaporates, it starts to become cool because of the cold atmosphere in the air and because of this cooling down of water leads to the formation of clouds.

Precipitation- Because of the high movements of the wings, the clouds start to collide and then fall back to the earth’s surface in the form of rain. Sometimes they also fall back in the form of snow, hail, sleet etc., depending upon the temperature.

Runoff or Infiltration- After precipitation, the water either flows to the water bodies called runoff or is absorbed into the soil, called infiltration.

Causes of Water Pollution

There are many reasons for water pollution. Some of the reasons are directly affected by water pollution and some indirectly. Many factories and industries are dumping contaminated water, chemicals, and heavy metals into major waterways as a result of direct water pollution. 

One more reason for water pollution is the use of modern techniques in farms. Farmers apply nutrients such as phosphorus, nitrogen, and potassium in the form of chemical fertilizers, manure, and sludge. It causes farms to discharge large quantities of agrochemicals, organic matter, and saline drainage into water bodies. It indirectly affects water pollution.

Pollutants can be of various types such as organic, inorganic, radioactive etc. Water pollutants are discharged either from one point from pipes, channels etc., which are called point sources or from various other sources. They can be agricultural areas, industries etc., called dispersed sources. 

Some of the major forms of water pollutants are as follows:

Sewage- Domestic sewage from homes contains various forms of pathogens that threaten the human body. Sewage treatment reduces the risk of pathogens, but this risk is not eliminated. 

Domestic sewage majorly contains nitrates and phosphates, and excess of these substances allows the algae to grow on the surface of water bodies. Due to this, the clean water bodies become nutrient-rich water body and then slowly, the oxygen level of water bodies reduces. This is called eutrophication or cultural eutrophication (if this step rapidly takes place by the activities of humans). This leads to the early death of water bodies.

Toxins- The industrial or factory wastes that are not disposed of properly and contain chemicals such as mercury and lead are disposed of in the water bodies making the bodies toxic, radioactive, explosive and cancerous.

Sediments- Sediments are the result of soil erosion that is formed in the water bodies. These sediments imbalances the water bodies ecologically. They also interfere in the reproductive cycle of various aquatic animals living in the water.

Thermal pollution- Water bodies get polluted because of heat, and excess heat reduces the oxygen level of the water bodies. Some of the species of fish cannot live in such water bodies with very low oxygen levels. The disposal of cold waters from the power plants leads to increased thermal pollution in the water bodies.

Petroleum oil pollution- The runoff of oil into the water bodies, either accidentally as happened in 2010 in the Gulf of Mexico, or intentionally, leads to an increase in water pollution.

As water is an important element of human health, polluted water directly affects the human body. Water pollution causes various diseases like typhoid, cholera, hepatitis, cancer, etc. Water pollution damages the plants and aquatic animals present in the river by reducing the oxygen content from the water. Polluted water washes the essential nutrients which plants need out of the soil and also leaves large amounts of aluminium in the soil, which can be harmful to plants. 

Wastewater and sewage are a by-product of daily life and thus produced by each household through various activities like using soap, toilets, and detergents. Such sewage contains chemicals and bacteria which are harmful to human life and environmental health. Water pollution also leads to an imbalance in our ecosystem. Lastly, it also affects the food chain as the toxins in the water bodies are consumed by aquatic animals like fish, crabs etc., and then humans consume those animals forming turmoil. 

Sometimes our tradition also becomes a cause for water pollution. Some people throw the statues of deities, flowers, pots, and ashes in rivers.

There are various standards to define water quality standards. Water meant for swimming may not be clean enough for drinking, or water meant for bathing may not be good for cooking. Therefore, there are different water standards for defined:

Stream standards- Standards that define streams, lakes, oceans or seas based on their maximum use.

Effluent standards- Define the specific standards for the level of contaminants or effluents allowed during the final discharge of those into the water bodies.

Drinking water standards- Define the level of contamination allowed in water that will be supplied for drinking or cooking in the domestic areas.

Different countries regulate their water quality standards through different acts and amendments.

While many of the solutions for water pollution need to be applied on a broader macro-level for that individual, companies, and communities can have a significant and responsible impact on the water quality. Companies, factories have to dispose of leftover chemicals and containers properly as per the product instructions. Farmers also have to reduce the use of nitrates and phosphates from fertilizers, pesticides, and contamination of groundwater. 

The Swachh Bharat Mission of the government had led to reduced groundwater contamination. Under the Namami Ganga program, the government has initiated several major projects to clean Ganga. Along with all these steps, conservation of water is the very basic and important step towards water conservation and should be followed globally, treatment of sewage before their disposal in the water bodies and using environment-friendly products that do not form toxins when dissolved in water. These are some small steps that have to be taken into consideration by every human being.

As we all know, “Water is life’s matter and matrix, mother and medium. There is no life without water.” We have to save water. We must keep the water clean. If everyone will follow their responsibility against water to protect it from getting polluted then it will be easy to get clean and healthy drinking water. Clean water is a must for us and our kids' present, future, and healthy environment. 

We cannot just live with contaminated waters filled with toxins and no oxygen. We cannot see our wildlife being destroyed and therefore, immediate steps have to be taken by groups of people to first clean the already contaminated water bodies and then keep a check on all the surrounding water bodies. Small steps by every individual can make a huge difference in controlling water pollution.

Water Pollution Prevention

Conserve Water 

Our first priority should be to conserve water. Water wasting could be a big problem for the entire world, but we are just now becoming aware of it.

Sewage Treatment 

Cleaning up waste materials before disposing of them in waterways reduces pollution on a large scale. By lowering its dangerous elements, this wastewater will be used in other sectors or in agriculture.

Usage of Eco-Friendly Materials

We will reduce the amount of pollution produced by choosing soluble products that do not alter to become pollutants.

Water contamination is the discharge of pollutants into the water body, where they dissolve, are suspended, are deposited on the bottom, and collect to the point where they hinder the aquatic ecosystem's ability to function. Water contamination is brought on by toxic compounds that easily dissolve and combine with it and come from factories, municipalities, and farms.

Healthy ecosystems depend on a complex network of organisms, including animals, plants, bacteria, and fungi, all of which interact with one another either directly or indirectly. In this article, we read about water pollution, its causes and prevention. With this, we have come to the end of our article, in case of any other doubts, feel free to ask in the comments.

FAQs on Water Pollution Essay

1. What are the effects of water pollution?

Water pollution has a great impact on human health. Water pollution kills. It's been recorded that in 2015 nearly 1.8 million people died because of water pollution. People with low income are exposed to contaminated water coming out from the industries. Presence of disease causing pathogens in drinking water are the major cause of illness which includes cholera, giardia, and typhoid. Water pollution not only affects human health but also our environment by causing algal bloom in a lake or marine environment. Water pollution also causes eutrophication which suffocates plants and animals and thus causes dead zones. Chemicals and heavy metals from industrial and municipal wastewater contaminate waterways and harm aquatic life.

2. What are the causes of Water pollution?

Water being a universal solvent is vulnerable to pollution as it dissolves more substances than any other liquid on earth. Therefore, water is easily polluted. Toxic substances from farms, towns, and factories readily dissolve into water and mix with it, resulting in water pollution. Agricultural pollution is one of the major causes of contamination in rivers and streams. The use of excessive fertilizers, pesticides, and animal waste from farms and livestock operations lets the rain wash the nutrients and pathogens—such as bacteria and viruses—into our waterways. The other major cause of water pollution is used water,  termed as wastewater which comes from our sinks, showers, toilets and from commercial, industrial, and agricultural activities. It's been reported that the world's 80% wastewater flows back into the environment without being treated or reused. Oil spills and radioactive waste also cause water pollution to a great extent.

3. How to prevent water pollution?

It is important to keep our water bodies clean so we can take the following preventive measures to prevent from water pollution:

Chemicals like bleach, paint, paint thinner, ammonia, and many chemicals are becoming a serious problem. Dumping toxic chemicals down the drain or flushing them down the toilet can cause water pollution. Thus, proper disposal is important. Also, household chemicals need to be recycled.

Avoid buying products that contain persistent and dangerous chemicals. Buying non-toxic cleaners and biodegradable cleaners and pesticides cut down on water pollution.

Prevent from pouring fats or greasy substances down the drain as it might clog the drain resulting in the dumping of waste into yards or basement which can contaminate the local water bodies.

4. What is the role of medical institutions in polluting the water?

Pharmaceutical pollution affects aquatic life and thus there is a need to take preventive measures. Consumers are responsible for winding up pharmaceutical and personal care products in lakes, rivers, and streams. There's a lot of unused and expired medication that can potentially get into the water if not disposed of properly.

5. What are the major kinds of pollution?

The three main types of pollution are air pollution, water pollution or soil pollution. Some artificial pollution is also there, such as noise pollution. Factors leading to such pollution include:

Air Pollution: Industrial emissions, fires, traffic and transportation, burning of chemical waste, etc.

Water Pollution: No proper sewage disposal, pesticides in farms leaking into water bodies, industrial waste dumped into water bodies, etc.

Soil Pollution:  Oil spills, acid rains, irresponsible disposal of trash, chemical waste, etc.

Noise Pollution: Honking of horns, construction activities, loud parties, etc.
