Hydro-Agricultural Development, Integrated Water Resources Management in Climate Variability and Agricultural Migration Context in the Plandi 2 Sub-Watershed of Upper Mouhoun, Burkina Faso

Burkina Faso is characterised by unfavourable hydrological conditions and the population's need for water to increase. In response, the authorities developed a policy of water resource mobilisation to satisfy the requirement of agropastoral and domestic needs. The Hauts-Bassins region benefited from these developments with the transfer of agro-pastoral populations. Natural resources are subject to anthropic pressure, consequences of the transfer of populations and the spontaneous movements attracted by these developments. The objective of this paper is to analyse the field implementation of Integrated Water Resource Management (IWRM) in the context of pressure on natural resources and climate variability. The methodology combines participatory, spatial and systemic approaches. The sub-watershed shelters a perimeter developed for hydro-agricultural purposes and has received a significant migratory flow of agro-pastoralists looking for "new land" since the 1970s. In 2018, 78.
