Abstract

The pressure constantly increases for the use and occupation of unexplored areas, concomitantly degrading natural resources. On the other hand, national, state, and municipal laws have arisen to regulate and preserve sites for environmental sustainability, such as Areas of Permanent Preservation (APP) and Legal Reserves. Nevertheless, the significant territorial extension and the multiple legislation make it difficult to define these areas. A relevant instrument to solve this issue is the geoenvironmental mapping of the territory. This work sought to delimit effectively regulated areas for use and occupation based on the geoenvironmental mapping of a section of the municipality of Ubajara, Ceará. Therefore, it was necessary to analyze the hypsometry, slope, water resource, and soil and delimit the APP and Conservation Units. The mapping revealed 15.67% of APP and 37.44% of use and occupation areas, being 46.88% effectively regulated for the use and occupation of the soil with diverse economic activities – such as agricultural, forestry, and pastoral-contemplated in the Ubajara master plan.
