LAND USE CHANGES IN THE SOLOMOUGOU WATERSHED FROM 1984 TO 2021 (NORTHERN COTE DIVOIRE)

Human activities affected Land use changes bya complex dynamic process, whitch affects natural resources. Poro region in general, and the Solomougou watershed in particular, is characterized by favorable natural conditions for diversified agricultural production. Remote sensing shows the extent of land use change between 1986 and 2021. Diachronic analysis reveals a decline in natural formations (forests and savannahs) in favour of crops. Interpretation of the results shows the local causes of this change, highlighting farming and pastoral practices, economic factors, urban expansion, migratory flows and deforestation, which weakens the environment by stripping the surface layers. The brightness index of high-resolution Landsat images shows a strong degradation. All this raises questions about the future of farming in this region, whose products make an essential contribution to local and national markets.
