This WASH evidence paper was commissioned by the DFID Water and Sanitation (WASH) and Research and Evidence Division (RED) teams and undertaken by the DFID-funded Sanitation and Hygiene Applied Research for Equity (SHARE) research programme consortium. It is not a policy document, and does not represent DFID's policy position. The paper aims to:
- Provide an accessible guide to existing evidence including a conceptual framework for understanding how WASH impacts on health and well-being and a description of methods used for ascertaining the health, economic and social impacts of WASH
- Present the available evidence on the benefits and cost-effectiveness of interventions on WASH
- Identify what we do know and also what we do not know, and assess the robustness of the available evidence relating to the impact of WASH interventions.
- Disaggregate the benefits, where possible, by gender and poverty and the distribution of the global impacts across regions and economic status of countries.
