Rice and trees: Agrarian and landscape dynamics over 40 years on the coast of southern Senegal and The Gambia
We studied, at local scale, how the landscape dynamics of the Saloum and Casamance (Senegal) and The Gambia can reveal environmental crises and the resilience of agrarian.

| Résumé: | We studied, at local scale, how the landscape dynamics of the Saloum and Casamance (Senegal) and The Gambia can reveal environmental crises and the resilience of agrarian. The method is based on remote sensing diachrony in land cover maps, field observations (landscape and botany), and interviews on recent landscape changes and agriculture. The results found that the relationships between agriculture and forest cover were complex and varied in space and time. However, some general trends appear: the period of drought prompted changes but with the rainfall recovery, a regeneration in the mangroves and a restoration in most rice crops happened. The changes stayed within the range of metastability, showing the strong resilience of the ecosystems and of most anthroposystems. |
