Kousséri, a town in the Sahelian zone located in the far north of Cameroon, borders Chad and Nigeria, all member countries of the Lake Chad Basin Commission (LCBC). Made up of different peoples and indigenous populations, the progression of drought and the drying up of Lake Chad linked to climate change has a major impact on the economic activities of the populations. The disappearance of certain water points leads to competition for scarce natural resources and creates inter-community tensions and conflicts, which this book aims to study.
