Despite great strides in improving sanitation in developing countries, some 2.4 billion people worldwide lack access to adequate sanitation facilities and the poorest and most vulnerable members of society are often not reached. Sustainability is one of the key challenges in CLTS and the wider WASH sector. Whether sanitation improvements endure depend on issues of equity and inclusion, social norms, physical infrastructure, sanitation marketing, monitoring and verification, post-ODF follow-up and the roles and responsibilities of governments, NGOs and donors. The achievement of “open defecation-free” status is now recognised as only the first stage in a long process of change and sanitation improvement.
This book, edited by the Sanitation Learning Hub, examines these challenges, asking questions such as how we ensure that people access sanitation and sustain related behaviours, and how we reach the poorest with toilets that are suitable for their needs. It develops key themes by exploring current experience, innovations and insights, as well as identifying a future research agenda and gaps in current knowledge, and making recommendations and practical suggestions.
