Sanitation and Hygiene Thematic Window

3ie and the Water Supply and Sanitation Collaborative Council (WSSCC) are partners on the Evidence Programme on Sanitation and Hygiene.

This programme aims to build the evidence base on effective sanitation and hygiene programmes in low- and middle-income countries. It has funded impact evaluations, systematic reviews, an evidence gap map, a study on effective advocacy approaches and a mid-term review of WSSCC.

Formed in 2014, 3ie and WSSCC’s partnership brings together two organisations that are committed to closing evidence gaps and improving outcomes for people living in poverty. WSSCC is the only United Nations body devoted solely to the sanitation needs of the most vulnerable and marginalised people. In collaboration with its members in 150 countries, WSSCC advocates for the billions of people worldwide who lack access to sanitation, shares solutions that empower communities and operates the Global Sanitation Fund.

The review synthesises evidence on the extent of efforts to provide services for disadvantaged and vulnerable populations.
