This work is part of the perspectives of our doctoral research which focuses on land dynamics and their impacts on the agro-pastoral space. We wanted to get away from the overly academic nature of the thesis to exploit its economic contours in relation to the urbanization and development policies of the area. The Dakar-Thiés-Mbour triangle which contains the Saféne country is undergoing infernal urban mutations, a phenomenon supported first by the State through its master plan for territorial development and planning. Then by the private sector, not only to quench its land gluttony, but to establish investments, given the favorable territorial offer of the area. This situation will be symbolized by the transfer and installation of many infrastructures, pushing back the limits of rurality on a daily basis and a significant reduction in agro-pastoral areas. This will be followed by a vertiginous drop in production, given the difficulties linked to the practice of these activities.
