In the context of climate change, socio-economic development of a region depends on its ability to adapt to adverse climate effects. However, a good and sustainable adaptation to these effects requires knowledge of the evolution of future climate. This study aims, the projection of some climatic parameters (temperature and rainfall) of the GOH region (center-west of the cöte d’ivoire) for the 2020, 2050 and 2080 by a model of statistical downscaling (SDSM 4.2.9). To do this, this model includes observational data and data anthropogenic emissions scenarios A2 (pessimistic) and B2 (optimistic). According to the scenarios, temperatures would experience an increase. While rainfalls would decrease in the region. These temperature increases and decreases in rainfall observed could have consequences on the development of the region.
