Vision 2030 : the resilience of water supply and sanitation in the face of climate change : technical report

This report presents the findings of research into the projected impact of climate change on water and sanitation services by 2020 and by 2030. The study represents the first attempt to address this issue at a global level. The report is particularly focused on low- and middle-income countries, but has global relevance. It provides an analysis of the resilience of water supply and sanitation technologies, and of management approaches. It also reviews the policy implications of the findings, identifies hotspots where attention is particularly needed and points to research needs. It draws on background studies into the resilience of water and sanitation technologies, decadal climate forecasts for 2020 and 2030, and projections of water and sanitation coverage by 2020. The main technologies used for water supply and sanitation were assessed to determine resilience. They were categorized as to whether resilience was high (resilient to most possible climate changes), medium (resilient to a significant number of possible climate changes) or low (resilient to a restricted number of climate changes).
