Water, sanitation and hygiene: the foundation for building resilience in climate-vulnerable communities

Case Summary: 

Climate change is already affecting rainfall and weather patterns, increasing the frequency and severity of floods, droughts, storm surges, temperature extremes, and sea level rises. As a normal part of everyday life, access to clean water, decent toilets and good hygiene can help people cope with these disruptions. Around 90% of extreme weather events are related to water – be they through droughts, floods or storms. Natural disasters can often damage or contaminate water sources, affecting the overall availability of water. But as it stands, only 1% of climate finance is invested in providing and protecting water, sanitation and hygiene (WASH) services for vulnerable communities.

In collaboration with the University of East Anglia's Water Security Research Centre, WaterAid undertook a study to explain how WASH builds people’s resilience to climate change, especially those who are most vulnerable to its effects.

This report, which involved input from across WaterAid, in particular from the Programme Support Unit (PSU) of WaterAid UK, includes case studies from a variety of countries, including Bangladesh, Burkina Faso, Eswatini, Ethiopia, Ghana, India and Nepal, each demonstrating what must be done now to improve WASH services and address current challenges, in order to increase community resilience to climate change.
