For the poorest urban residents, one of the most significant ways in which climate change is affecting their lives is through access to water and sanitation.

In sub-Saharan Africa and south Asia, water and sanitation service providers are struggling to respond to the needs of communities, and climate change is making it harder for these providers to expand services to keep pace with urbanisation. This challenge represents a major threat towards the ability of cities to adapt to climate change and could compromise their future sustainability.

This report analyses the impacts of climate change on access to water and sanitation across cities and towns in seven countries. It outlines the challenges that service providers are facing and documents initiatives that are taking place to tackle the issue. Based on this analysis, WSUP presents four recommendations for helping water and sanitation providers to tackle the threat caused by climate change.
