Water and sanitation

Water and sanitation are pivotal elements of the Sustainable Development Goals (SDGs), primarily encapsulated in SDG 6 (Clean Water and Sanitation). This goal seeks to ensure the availability and sustainable management of water and sanitation for all by 2030. This objective directly addresses the current global water crisis, where nearly 2.2 billion people live without access to safe water, and about 4.2 billion lack access to adequate sanitation.

By focusing on improving water quality, increasing water-use efficiency, implementing integrated water resources management at all levels, and protecting and restoring water-related ecosystems, SDG 6 addresses not only direct human needs but also the broader ecological health of the planet. Furthermore, efforts towards achieving SDG 6 indirectly promote several other SDGs.

For instance, water and sanitation are crucial to achieving SDG 3 (Good Health and Well-being), as clean water and proper sanitation facilities reduce the spread of water-borne diseases and significantly lower child and maternal mortality rates. Likewise, they are foundational to SDG 4 (Quality Education), given that the provision of water and sanitation facilities in schools significantly impacts the attendance and performance of students, particularly for girls.

SDG 2 (Zero Hunger) also intersects with water and sanitation, as sustainable and efficient water management is critical for agriculture, which remains the largest global water consumer. The necessity of water for food production and the potential impact of improved water management on crop yields and livestock health makes SDG 6 integral to achieving zero hunger.

SDG 6 contributes to SDG 1 (No Poverty) and SDG 8 (Decent Work and Economic Growth) as well. Access to clean water and sanitation can enhance economic productivity by reducing time spent gathering water, reducing healthcare costs due to water-related diseases, and even creating jobs in water and sanitation services sectors.

In terms of environmental impact, the sustainable management of water resources is essential for SDG 13 (Climate Action), as water is a key factor in managing climate change due to its role in agriculture and energy production.

This chapter explores how rapid urbanization and climate change threaten urban water security, using Windhoek, Namibia, as a case study. It highlights how adaptive, innovative approaches—such as resource-efficient systems and resilient storage—can transform hydrosocial systems to ensure sustainable water access, supporting healthier, more resilient cities (SDG 11) and safeguarding public health (SDG 3). The Windhoek experience underscores the importance of rethinking development pathways to build adaptive, equitable urban water systems in a changing world.

Water Matters: Achieving the Sustainable Development Goals, Volume , 1 January 2024

This chapter emphasizes the vital role of water in alleviating multidimensional poverty (SDG 1) by enhancing agricultural productivity, ensuring access to safe drinking water, and restoring ecosystems. Recognizing water as an economic, social, environmental, and institutional good, the chapter advocates for integrated water interventions that support sustainable watershed management, equitable benefit sharing, and ecosystem service expansion. Using a case study from North Gujarat, India, it highlights how water infrastructure development can both reduce and inadvertently deepen inequalities, underscoring the need for sustainable, equitable water management strategies that promote healthier communities and resilient urban environments (SDGs 11 and 3).
The cascading effects of biodiversity decline on human well-being present a pressing challenge for sustainable development. Conservation efforts often prioritize safeguarding specific species, habitats, or intact ecosystems but overlook biodiversity's fundamental role in providing Nature's Contributions to People (NCP) in human-modified landscapes.
Pakistan's water resources experiencing mounting pressure. UN SDG 6 provides a roadmap for achieving sustainable water management. Long-term planning and community engagement are key to success. Policy recommendations include efficient pricing and climate change integration.
The authors put forward a mathematical model for examining the impact of water, sanitation and hygiene (WASH) services on reducing the transmission of waterborne diseases such as enteric diarrheal disease (EDD). It is found that wastewater and sewage treatment (WST) control has the most significant impact in terms of WASH interventions employed. The findings have could have very important public health potential and tie in strongly with the goals of SDG 6.
This study supports SDGs 3, 6, and 14 by highlighting the importance of freshwater biodiversity for human and planetary health, and suggesting that local and regional efforts for monitoring and improving ecosystem health are essential for reversing the current crisis in this area.
