Mathematica is evaluating the Millennium Challenge Corporation’s (MCC) Agricultural Development Project in Burkina Faso to understand the project’s effects on improved agricultural outcomes and land tenure security. The project included (1) the construction of an irrigated perimeter, known as the Di perimeter; (2) support for water management through technical assistance for integrated water resource management institutions and support for local water user associations to improve management of irrigation perimeters; (3) training of farmers, livestock holders, and other actors in the agriculture and livestock value chains; and (4) the rehabilitation of markets and the development of a market information system to collect and disseminate agricultural prices via mobile phones. This interim report provides results from Mathematica’s mixed-methods interim analysis that relies on quantitative and qualitative data collected between January and April 2019.
