Addressing sustainability factors for rural sanitation, this paper represents one of the few systematic reviews of sanitation slippage and sustainability ‘post-intervention’. Between 2014 and 2018 SNV Netherlands Development Organisation implemented The Sustainable Sanitation and Hygiene for All (SSH4A) approach in 15 African and Asian countries. The authors of this paper carried out focus group discussions and interviews with beneficiaries, implementers, and decision-makers in order to assess sustainability factors. The authors suggest that understanding the programmatic and contextual factors that affect long-term sanitation coverage may allow for greater program impact through implementation adaptation.
A comparison of sustainability factors and slippage rates, allowed the authors to illustrate the the response of delivery systems to barriers and enablers. There is potential for other to replicate this methodology in other settings and contexts.
