Since 2012, development actors have promoted supplemental irrigation from farm ponds to cope with rainfall variability in Burkina Faso, but few farmers have adopted the innovation. Although harvesting runoff water in ponds is an old practice in Sahelian Burkina Faso, farmers were not accustomed to irrigating crops with stored rainwater. In the cont...
Much of the research on behavioural preferences as predictors of compliance with regulations aimed at reducing the transmission of COVID-19 has focused on developed countries, with very little consideration of African countries. We conduct an online survey (n = 1503) considering beliefs, and individual and social preferences as predictors of compli...
This study uses an online laboratory experiment and a post-experimental survey to test whether the Mastercard Foundation (MCF) scholarship programme causally influences the creation of cognitive social capital among University of Pretoria recipients. Cognitive social capital, which is based on commonly shared norms among subjects, leads to honest a...

Such experiments are often conducted with university students and framed in an abstract manner. This raises questions about whether the findings of these experiments provide reliable insight...

How have the rules and norms of commensality withstood th...
Context: Addressing the environmental impact of agriculture requires a comprehensive analysis of the system at stake, and accounting for the social diversity (i.e. social groups involved in farming and relationships between them) is particularly important for designing efficient policies aimed at mitigating these impacts. However, the integration o...
In social species, the transmission and maintenance of infectious diseases depends on the contact patterns between individuals within groups and on the interactions between groups. In southern Africa, the Cape buffalo (Syncerus caffer caffer) is a vector for many pathogens that can infect sympatric livestock. Although intra-group contact patterns o...
Little is known about the effect of social information on the ability of groups to overcome a collective action problem. By social information, we mean information about the actions of other group members and their effects. This thesis aims to shed new light on this subject. In the first chapter, we analyze the effect of different levels of informa...
Cet article rend compte d'une mobilisation sociale de grande ampleur contre la concession privée d'eau potable à La Paz-El Alto en Bolivie. Cette concession fut pourtant érigée durant sa décennie d'activité (1997-2007) en un modèle de participation privée " bonne pour les pauvres " (pro-poor). Il existe assurément de fortes dispositions structurell...
