What constitutes success for CLTS? Webinar recording

Printer-friendly versionPrinter-friendly version

On the 22nd July 2015, a webinar on "What constitutes success for CLTS? – Measuring community outcomes and behavior change" was hosted under the Knowledge Management initiative of the Building Demand for Sanitation (BDS) program of the Bill & Melinda Gates Foundation. The webinar was organized by Euforic Services, the SuSanA secretariat and the Stockholm Environment Institute.

  • Hans-Joachim Mosler, Head of Environmental and Health Psychology, Eawag
  • Jonny Crocker, Research Assistant at The Water Institute at UNC, Chapel Hill

Format: The webinar had quite an innovative format, it was run in a "chat show" format - basically a set of interview questions to the panel - and without powerpoint presentations. It also included four separate break-out rooms where participants could interact in a smaller group, therefore allowing for more interactions.

What was discussed: "It is startling that there seems to be no consensus about what constitutes success for CLTS programmes. Is 30% an acceptable success rate? How can these rates be optimized? and; what should be our response to communities that do not become defecation free?" Questions and issues included:
1. ODF may be better suited for motivating communities than measuring success and is not a good metric for comparing communities due to its binary nature;
2. Low overall success rates suggest we are missing an opportunity to better target CLTS to specific communities and consider alternate sanitation strategies where CLTS is not appropriate;
3. We need better data and understanding of how to successfully change long-term social norms.

The recordings are now available as videos on youtube but also as sound-only mp3 files:
