Review of the slippage factors from open defecation-free (ODF) status towards open defecation (OD) after the Community-Led Total Sanitation (CLTS) approach implementation.

Open-defecation (OD) is one of the most widespread sanitation practices in low-income countries. This practice often causes diarrheal diseases and 760,000 deaths per year. To eradicate OD, several approaches have been developed, including Community-Led-Total Sanitation (CLTS) which is a participatory and community approach. The specificity of CLTS is that it is managed by the community itself, as its name implies, and that no subsidies or financial contributions from outside the community are used in the construction of the facilities. Although, the CLTS is effective in the short-term for eradicating OD, the long-term results are not encouraging: Open-Defecation-Free (ODF) communities revert to OD or partially use latrines. The present research is based on literature review and authors investigation in Burkina Faso. It was conducted to provide a comprehensive understanding of the factors that affect the sustainability of ODF-status leading to slippage in communities. It was found that these factors can be grouped into five categories: behavioral and social, technological, organizational, and vulnerability factors. The last one, socio-political factors, is a contribution from the authors as it was not reported in the literature yet. The authors have proposed graphical synthesis of all the slippage factors and their associated categories in the ODF-communities. Finally, authors have suggested that to sustain ODF-status of communities: include all stages of the sanitation value chain (SVC) in the CLTS, the follow-up activities after achieving ODF-status must be planned well in advance, sanitation marketing should be developed and the sanctions against the practice of OD have to be reinforced. Governments and donors should pay particular attention to the following options: raising awareness and regular monitoring after ODF certification, encouraging research on sustainable and pro-poor sanitation technologies, and building the capacity of implementing actors including facilitators. While obtaining ODF status is materialized by a sign with the status on it, this paper drew the attention of CLTS implementers to the lack of materialization of slippage when it occurs, and the absence of studies on the evolution of the community sanitation scale after ODF-status.
