Sanitation and Hygiene Evidence Programme
Globally, more people have access to clean water, sanitation and hygiene (WASH) than ever before. But we are still a long way from achieving the Sustainable Development Goal of ensuring the availability and sustainable management of water and sanitation for all. 3ie, in partnership with the Water Supply and Sanitation Collaborative Council (WSSCC), developed this programme to build the evidence base in L&MICs and to support global efforts towards increasing equitable access to and use of WASH services.
3ie and WSSCC’s partnership brought together two organisations 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.
Through the 3ie sanitation and hygiene programme, we funded impact evaluations, systematic reviews, an evidence gap map, a study on evaluating advocacy approaches and a midterm review of WSSCC.

WASH evidence gap map on promotional approaches
To achieve universal targets and reach the most disadvantaged populations, we need access to high-quality evidence on what WASH promotional approaches work for different populations. 3ie’s latest WASH evidence gap map provides an overview of the evidence base on what works or not in households, schools, health facilities and communities in L&MICs. The online map provides an interactive visualisation of the evidence base, displayed in a framework of relevant interventions and outcomes.
