Summary
• Water quality is crucial for sustainable development, impacting health, agriculture, ecosystems, and industry.
• Safe water prevents diseases, improves food security, and supports economic growth, while poor quality water has negative consequences.
• SDGs outline goals for water quality and sanitation, but challenges like water scarcity, pollution, and infrastructure limitations exist.
• Technological advancements, partnerships, and integrated water management offer promising solutions for achieving water quality goals.
We live on water, it is a basic necessity, and water is a human right to be clean and safe. But the majority of the population worldwide has no access to safe and clean water, and water contamination is on the rise. Water quality is an issue that the UN knows has a sustainable development value, and there’s a water and sanitation target in the SDGs.
What is the importance of water quality in sustainable development?
Access to safe and clean water is critical for achieving sustainable development. Here are some of the ways that water quality contributes to sustainable development:
- Health: Waterborne diseases are a major health risk, and access to safe and clean water is essential for preventing the spread of diseases such as cholera, typhoid fever, and diarrheal diseases. According to the World Health Organization, over 800,000 people die each year from water-related diseases, and many of these deaths could be prevented with improved water quality.
- Agriculture: Agriculture is a major user of water, and the quality of water used for irrigation can have a significant impact on crop yields and food security. Water pollution can damage soil fertility, reduce crop yields, and threaten food security, particularly in developing countries.
- Ecosystems: Water quality is critical for maintaining healthy aquatic ecosystems and the biodiversity they support. Healthy aquatic ecosystems provide essential services, such as water purification, flood control, and nutrient cycling that are critical for sustainable development.
- Industry: Many industries rely on water for their operations, and access to clean and reliable water is essential for economic growth and development. For example, the tourism industry depends on clean and attractive water bodies, and the technology industry relies on high-quality water for manufacturing and cooling.
How does access to safe and clean water contribute to sustainable development?
Access to safe and clean water is critical for achieving sustainable development, as it impacts health, agriculture, ecosystems, and industry. Safe and clean water helps to prevent waterborne diseases, improve crop yields and food security, maintain healthy aquatic ecosystems, and support economic growth and development.
Sustainable Development Goals
The Sustainable Development Goals (SDGs) are a set of 17 goals adopted by the United Nations in 2015 to address global challenges such as poverty, inequality, and environmental degradation. Goal 6 of the SDGs is specifically focused on water and sanitation, and includes targets for improving water quality, increasing access to safe and affordable drinking water, and reducing water pollution. Here are some of the key targets of Goal 6:
- By 2030, achieve universal and equitable access to safe and affordable drinking water for all.
- By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater, and substantially increasing recycling and safe reuse globally.
- By 2020, protect and restore water-related ecosystems, including mountains, forests, wetlands, rivers, aquifers, and lakes.
The SDGs are a call to action for governments, industry, and the public to work together to achieve sustainable development, and water quality is a critical component of this effort.
Challenges to Achieving Water Quality in Sustainable Development
Even though water quality is an integral part of sustainable development, there are still many hurdles to the SDGs. Some of the biggest issues:
Water Scarcity
There are areas where water resources are at a minimum, in both dry and semi-dry areas. This problem is only being exacerbated by climate change and population, and there must be novel ways to ensure that more water is available and less water is lost. More than 2 billion people exist in water stressed countries, and more are expected to migrate in the coming decades, according to the UN.
Water Pollution
In many countries around the world, water pollution is a major issue and can be harmful to human health, ecosystems and economic growth. Eighty per cent of wastewater, the UN reports, is sent out into the environment in untreated form and ends up in rivers, lakes and oceans. Water conservation will take better water-treatment technology, better regulations, and collective effort by all.
Water Infrastructure
Water infrastructure needs to be maintained and upgraded in order to guarantee access to clean water for all. But financing water infrastructure remains a perpetual issue, and most communities are unable to afford much improvement. As the American Society of Civil Engineers estimates, to preserve and enhance water quality in the United States, drinking water infrastructure and wastewater infrastructure will need \$123 billion and \$298 billion respectively over the next 20 years.
Opportunities for Achieving Water Quality in Sustainable Development
The good news is that there are a number of ways to improve water quality for sustainable development. Voici some of the best opportunities:
Innovative Technologies
New technologies – water treatment and precision agriculture, for example – can open up more water and save more water. Desalination equipment, for instance, can turn sea or brackish water into fresh water, and precision agriculture can use less water and increase crop productivity through optimum irrigation with sensors and data. The investments in R&D necessary to optimize these technologies and make them widely available will continue.
Public-Private Partnerships
Private-public partnerships can fill the water infrastructure funding void and promote government, industry and public cooperation. These partnerships can tap the capabilities of both sectors in support of SDGs regarding water quality. The World Bank, for instance, has a Water Global Practice on public-private partnerships for water supply and sanitation, and the 2030 Water Resources Group engages with governments, industry and civil society on sustainable water.
Integrated Water Resource Management
Integration of water resources includes integrated management of water resources – surface water, groundwater, and watersheds. The method can reduce water shortage and water pollution and support sustainable development. In-depth water management demands engagement from the various actors – state departments, users and civil society. International Water Management Institute and Global Water Partnership: both organisations work towards integrated water management.
Water quality is a cornerstone of sustainable development and the SDGs are an instrument to tackle water quality. Nonetheless, there are some breakthrough solutions for water quality: novel technologies, public-private collaborations, integrated water resource management. Sustainability is the collective work that all stakeholders must do in order to realize it, and the environment is no exception. We can make sure that every human is supplied with healthy and clean water, and that our ecosystems and economies are vibrant and resilient through collective action.
