LAND USE LAND COVER DYNAMICS AND LOCAL CLIMATE CHANGE IN THE BOSSEMATIE NATURE RESERVE, COTE DIVOIRE

The study on the impact of land use and land cover (LULC) on climate has highlighted the close interactions between spatial dynamics of terrestrial cover and climatic variables within the Bossematie Nature Reserve (BNR) in Cote dIvoire. A diachronic analysis of land use and land cover changes over the 1990 2020 periodreveals a significant decline in dense vegetation, replaced by agricultural land, human settlements, and degraded surfaces. This dynamic is primarily driven by the intensification of anthropogenicactivities in and around the reserve. However, climate evolution, particularly through the analysis of temperature and precipitation time series, indicates a trend shift. A progressive rise in temperatures has been observed since 1986, along with an increase in annual rainfall totals after 2008. These changes coincide with disturbances in vegetation cover, suggesting a probable link between deforestation, alteration of the local microclimate, and redistribution of rainfall regimes. These findings underscore the need for improved land management practices around protected areas to mitigate adverse effects on ecosystems and local climate. It is therefore essential to integrate climate considerations into spatial planning policies and to streng the nbiodiversity conservation efforts within the Bossematie Nature Reserve.
