From new evidence to better practice: finding the sanitation sweet spot

Abstract

A growing body of evidence shows that there is a strong causal link between exposure to poor sanitation and detrimental health, human capital, and economic outcomes. At the same time a number of recent impact evaluations of specific sanitation interventions show mixed results. This heterogeneity in findings raises the questions of whether and how the demonstrated benefits of improved sanitation can be consistently achieved through regular project implementation. This paper attempts to show that the benefits of improved sanitation can be consistently achieved through investing in interventions that address the drivers of latrine use and by divesting from interventions that do not address the drivers of latrine use.
