AGRICULTURAL APTITUDE OF LANDS AND CONFLICTING USES IN PERMANENT PRESERVATION AREAS OF RIBEIRÃO JACOBINA BASIN IN CÁCERES / MATO GROSSO STATE, BRAZIL

Abstract

The expansion of agricultural activities in areas of high environmental sensitivity results in negative effects on the environment. The objective of this work is to evaluate by geo-technologies the agricultural aptitude of lands and the conflicts of use in Permanent Preservation Areas (PPAs) along rivers and springs in the Ribeirão Jacobina Basin in Cáceres municipality / Mato Grosso State. Using a Geographic Information System, it was possible to intersect those maps referring to soil classes, relief, agricultural aptitude, land use/land cover. The Brazilian Forest Code and its determinations were used as basis for the evaluation of land use conflicts in PPAs. It was verified that 67.47% of the territory of the basin is suitable for livestock/agricultural activities. There are conflicts of land use in areas with occurrence of Humic Cambisols, Haplic Luvisols and Litholic Neosols in hilly relief with predominance of livestock. Land use/land cover within the APPs, demonstrated that 1,802 hectares of the basin correspond to areas of water resources protection, and from this total, 459 hectares are being used for livestock activities and 23 hectares for reforestation, and there are conflicts between current use and current legislation. It was concluded that work is needed to recover PPAs in the basin, aiming at maintaining water quality and availability
