The main objective of this study is to question the implications that climate change could have on Cameroon's agricultural exports through its agricultural production. Thus, we search through a Computable General Equilibrium Model (CGEM) to decompose the conditional logic chains resulting from a climate change on the agricultural exports of Cameroon by its agricultural production. After using the Cameroon MCS of 2014, for micro simulation and World Bank data on climate change (rainfall and temperature) in Cameroon in 2016, climate change impact simulations are introduced on the basis of pessimistic and optimistic assumptions drawn from a review of the literature and an expert consultation. Indeed, we observe a negative variation in the order of (-7.97%) of agricultural production and a downward variation in agricultural exports of about (-32.79%).
