Abstract:
In the north-western Atacora region, the rugged terrain limits access to agricultural land and creates a particular dynamic of land cover. The objective of this research is to simulate land cover in the 2050s in the mountainous area of northwestern Atacora in Benin. Landsat 5 TM images from 1988 and Landsat 8 OLI-TIRS from 2020 are the main data used. Supervised classification and modelling were performed with Idrisi Selva software. The annual regression rate is 18.30 % and the projection to 2050 predicts the disappearance of dense dry forests and a reduction of forest galleries and woodlands in favour of field and fallow mosaics (56.03 %) and tree and shrub savannas (25.23 %).
