Evolução da dinâmica do uso da terra entre 1985 a 2019 no estado do Ceará

Abstract

The search for responsible management of natural resources is one of the main needs to combat soil degradation, especially in the Brazilian Caatinga. For this, it is essential that the reality of those who use the land in this region be studied. In this context, Ceará stands out for being a state in which 95% of its territory is located in the semiarid region and to maintain its agricultural production, it needs to reduce the natural vegetation cover. This article aims to analyze the dynamics of land use in Ceará from 1985 to 2019. For this purpose, statistical data extracted from the MapBiomas Project with 5-year intervals were used, comparing them using pixel-scale maps 30m, covering the entire territory of Ceará. The results obtained showed that Ceará suffered a great reduction of forests (natural and planted) mainly in the years 1985, 2000 and 2019 and a gradual increase in the areas occupied by agriculture in the same period. The expansion of land use and occupation in the state was observed, decreasing the vegetation regions from 2000, confirming the expansion of the transition from vegetation cover to anthropic land use focused on agriculture and livestock.
