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.

The empirical analysis shows that unregulated water vending makes households without connection to pay higher tariffs for water. The paper among others recommends that tariffs at which vendors should sell water to customers should be set and closely monitored in order to ensure that households without connections have access to water at reasonable tariffs.
This book chapter advances SDG 3 and 6 by describing properties of water and importance of water to biomaterials and biology.
The SDG Impact of COVID-19 podcast series gathers expert opinion exploring the impact of COVID-19 on the Sustainable Development Goals. In this segment, we get the view of Virginia Gardiner, Founder and CEO of Loowatt.
This chapter advances SDG 6 and 11 by exploring the technological landscape of water purification in India, focusing on strategies for treatment of wastewater as a potential water source.
This chapter advances SDG 6 and 11 by reporting on the various laws and policy governing water supply in South Africa as well as the current state of water and wastewater infrastructure in South Africa.

Considering the significance of the indigenous knowledge systems toward addressing key environmental concerns, in this chapter, an attempt has been undertaken to address the indigenous knowledge system for water conservation and management.
The potential of electron-donating capability in methoxy groups of antioxidant containing protein (ACAP) as organic catalyst is restricted by its low isoelectric point. The goal of this study is to construct endure ACAP based metal-free organic catalyst for hydrogen production from electrolysis of noodle wastewater. The ACAP was coated thermomechanically on PVC sheet and its performance was tested during electrolysis of noodle wastewater. The morphological analysis, phase analysis, and elemental analysis of coated materials have shown a simultaneous pattern with electrolysis performances.
The planetary boundaries framework proposes quantified guardrails to human modification of global environmental processes that regulate the stability of the planet and has been considered in sustainability science, governance, and corporate management. However, the planetary boundary for human freshwater use has been critiqued as a singular measure that does not reflect all types of human interference with the complex global water cycle and Earth System.

Water footprint (WF) measures human appropriation of water resources for consumptive use of surface and ground water (blue WF) and soil water (green WF) and for assimilating polluted water (grey WF). Questions have been often asked about the exact meaning behind the numbers from WF accounting. However, to date environmental sustainability of WF has never been assessed at the sub-national level over time. This study evaluated the environmental sustainability of blue, green and grey WF for China's 31 mainland provinces in 2002, 2007 and 2012, and identified the unsustainable hotspots.
Chioma Blaise Chikere, 2017 second prize winner of the Green Sustainable Chemistry Challenge
In 2017, Chioma Blaise Chikere was awarded the second prize of the Green and Sustainable Chemistry Challenge. Her project “Eco-restoration of crude oil-polluted land in Nigeria” demonstrated how organic nutrients such as garden fertilizers and animal excreta can be used to degrade hydrocarbons, cleaning up the soils heavily contaminated by decades of oil spills and advancing SDGs 6, 13 and 15. Three years later, we caught up with Dr. Chikere to learn about her research journey.
