In Sudano-sahelian zone of West Africa, an important aspect of the current climate change impacts is the ecological systems evolution. Human pressure plays a great part in this evolution. Now it is question to develop adaptation strategies to climate change. In this order it is important to note that research at regional scales must be supplemented by sufficiently fine analyses on lower scales (rural district, village, small watershed, etc). So it will be possible to identify relevant strategies according rural diversity (agro ecological and socio-economic aspects, the 50 last years history of discussed agricultural development). The present study is led with these ambitions, as part of AMMA WP3.2 activities, in the village of Nankorola (12° 66’N ; 5° 74’ W), about 23 km2, in cotton basin of Mali. The Work is based on land occupation cartography and surveys. In 1952, village space distribution between crops, degraded vegetation and dense vegetation is respectively 54%, 37% and 9%. Currently, this distribution is 81%, 17% and 2%. The development of the cotton production, accompanied by destructive husbandries, the current staffing of livestock (1291 cattle, 991 sheep-goats and 131 donkeys) for a small area available for grazing (19% of the village land) are negative with natural vegetable cover and the soils to accentuate the effects of the climate. About climate, the local populations recognize a reduction in the rains, announce that winds become drier. They announce the degradation of the vegetation, soils and biodiversity. The satisfaction of the energy needs from the forest resources is compromised. In the same way, the complementary human food resources drawn from the forests and pastures rarefy. The adaptation to the new situation remains to be structured better. In this way, outside knowledge and technology are necessary.
