Biodiversity Project: Senegal-Mauritania Case Study

This lecture introduces the use of Geographic Information Systems (GIS) through a case study on the biodiversity project in Senegal and Mauritania. It covers the diversity of ecosystems, species, and genes over space and time, focusing on the Senegal River valley, its various ethnic groups, and activities. The project aims to address biodiversity loss caused by agricultural expansion and the increased use of certain tree species. It explains the selection and processing of LANDSAT images, supervised classification techniques, and the analysis of land cover changes over time. The lecture also discusses the results obtained from statistical analysis and spatial dynamics of land cover changes between 1984 and 2003.
