Abstract : In the far northern part of Cameroon, the shores of Lake Chad are in the most exposed zone to the risks of soil degradation due to environmental conditions, more severe climatic conditions and modes of uses and exploitation of natural resources (National Action Plan to combat Desertification (PAN/LCD) 2006). It is an area marked by degradation and decline of soil fertility, unsuitable cultivation practices, high extension of barren land, erosion, runoff, and decrease of fallows, overgrazing, and pesticides pollution.
