The aim of this project is to intergrate biophysical variables in a migration model in Burkina Faso. Those variables represent land use change and climatic variability in different regions of the country. We assume that these factors influence the model performance. Their impact will take place at a higher rate than for the demographic variables.
Available data are scale-dependent and differ between scales.
The results of these models improve our general understanding of the links between migration and environmental change. The decrease in rainfall during the 83-84 drought, just before the migration data, proved to have an explanatory power comparable to that of the demographic variables.
