Water, sanitation, and hygiene interventions for households, communities, health facilities and schools: findings from a sector-wide evidence gap map

October 10 @ 12:30 pm - 2:00 pm

Abstract 

To help achieve ambitious Sustainable Development Goals (SDGs), and reach the most disadvantaged populations, decision makers need access to high-quality evidence on what works in different contexts, and for different groups of people. 3ie’s sector-wide water, sanitation, and hygiene (WASH) evidence gap map provides an assessment of the evidence base for behavior change, health, and socioeconomic outcomes resulting from WASH promotional approaches in households, communities, health facilities and schools. WASH sector research is a truly multi-disciplinary field where academics aim to overcome disciplinary silos to answer relevant questions for policy makers, and have done so since at least the 1970s. The evidence map includes 367 completed or ongoing rigorous impact evaluations, across 87 developing countries, plus an additional 42 completed systematic reviews. Since the International Year of Sanitation 2008, there has been a ‘behavioural revolution’ in impact evaluation and related research towards conducting studies that answer questions about the best way to promote WASH technologies and sustain good practices. We articulate an intervention-outcome framework that incorporates these different promotional approaches and indicates the density and paucity of studies examining behavioural, health and socioeconomic outcomes. We also examine the extent to which studies examine equity and incorporate programming for particularly vulnerable groups, such as people living with disability.
