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 study supports SDGs 3 and 6 by analysing data from 88 low-income and middle-income countries and showing geographical disparities in access to clean water and sanitation facilities. These findings identify where efforts to increase access to safe water and sanitation have been successful over time, and highlight the need for targeted and tailored interventions to reach those communities and regions that have been left behind.
On Monday 24 August 2020 – at the beginning of World Water Week - RELX announced the winners of the 2020 RELX Environmental Challenge. Now in its 10th year, the RELX Environmental Challenge supports innovative solutions that improve sustainable access to safe water and sanitation where it is at risk, contributing to SDGs 1, 3, 6 and 10.

Tropical insects are astonishingly diverse and abundant yet receive only marginal scientific attention. In natural tropical settings, insects are involved in regulating and supporting ecosystem services including seed dispersal, pollination, organic matter decomposition, nutrient cycling, herbivory, food webs and water quality, which in turn help fulfill UN Sustainable Development Goals (SDGs). Current and future global changes that affect insect diversity and distribution could disrupt key ecosystem services and impose important threats on ecosystems and human well-being.
This study supports SDGs 3 and 6 by suggesting that current methods of cholera control are insufficient at achieving zero transmission of Vibrio cholerae in Haiti, and that large-scale cholera vaccination campaigns are needed alongside improvements in water and sanitation for long-term cholera elimination.
Each year the RELX Environmental Challenge is awarded to projects that best demonstrate how they can provide sustainable access to safe water or sanitation. In the past decade, the company has awarded $750,000 to projects and solutions that improve the world’s water quality and sanitation. This article, using innovative parallax storytelling technology, looks at the tangible impact of the RELX Environmental Challenge.

To mark the tenth anniversary of the RELX Environmental Challenge and the announcement of this year’s winners, we invite you to join us for SDG 6: From here to there - celebrating 10 years of innovation and exploring the next decade of WASH action, to take a look back over the past 10 years and to consider the decade of action ahead - what will it really take to achieve SDG6: clean water and sanitation for all?

This book chapter advances SDG 3 and 6 by exploring the feasibility/design implications for coastal reservoirs based on estimation of runoff, detailed assessment of water demand and estimation of water quality.
