The objective of Community-led Total Sanitation (CLTS) projects is to put an end to open defecation in rural villages. Open defecation is a widespread practice in many regions of the developing world, perpetuating a sanitation crisis. We conducted a series of behavioural games in 120 villages in the Koulikoro region of Mali to explore cooperative behaviour in those communities. CLTS is indeed a project that aims to foster collective action towards behavioural change in sanitation practices. We discuss within villages and between villages variation in cooperation. Does social structure help explain village-level heterogeneity ? Do individual and relational characteristics help explain individual-level heterogeneity ? Do community leaders play differently from others ? We also analyze two variants of the base game of voluntary contribution that allow for a coordination scheme (though open group communication and via the intervention of a group leader), in order to get closer to the way the CLTS project promotes behavioural change. Do gains from the base game depend on the quality of the leader ? Is there evidence of an interplay between village network influences and the coordination scheme ?
