%X Abstract. The desertification is a phenomenon that threatens to the biodiversity being the causes linked to the actions antropics where include the agricultural expansion, use inadequate of the soil, overgraze, burned, deforestation and populations concentrations, provoking environmental, social and economic changes. The present work objectified an analysis multitemporal of the vegetable covering of the municipal district of Cedro in the interior from Pernambuco through the supervised of the images classification, tends as base the years of 1986 and 2001.As result was observed for the year of 2001 in relation to 1986 a reduction of the vegetation of arboreal caatinga of 5,35% and in the shrub caatinga in 14,45% caused mainly by the wood extraction for firewood, coal and pasture area in the studied years. Reduction was also verified in the gallery forest in 0,6% that it was occupied by agricultural cultivations and in the category water in 0,26% indicating a drastic decrease of the capacity of storage of the dams of the area.
