Diagnóstico ambiental da Reserva Extrativista Marinha de São João da Ponta: subsídios para o planejamento ambiental

Abstract

The environmental assessment and analysis of the suitability of the occupation permit identification of the most critical areas in the level of degradation is extremely relevant for the establishment of conservation measures, conservation and recovery. This study aimed to conduct an environmental diagnosis of Marine Extractive Reserve of St. John the tip through GIS techniques. Analyses based on information that make up the landscape of CU, especially in the use and occupation of land and the relationships between some aspects considered in the work. The analyzes included aspects related to the use and occupation of land , the region's climate , soil composition and its geomorphology , water resources , fauna and flora , the conditions of life in the communities , the risk of erosion. It was found that the basin water resources are being degraded , the use and land cover still has degraded areas and a process of fragmentation is occurring in the landscape , especially in the vicinity of CU. Potential sources of landscape degradation of mangroves have been identified in the vicinity of the unit , compromising the quality and quantity of the supply of resources . Urbanization is the most influential factor on the CU because it exerts a pressure on the EXRES . Irregular situation with respect to legislation and environmental preservation were detected in the basin . In most of CU along watercourses use and land cover have an advanced stage of regeneration , which refers to the process of occupation of northeastern Paraense . Ecological corridors linking the upland forests are degraded and inadequate , especially for not meeting the environmental function determined by the Forest Code , predominating in these areas pastures . An efficient environmental control policy is needed for these areas, and environmental planning appropriate to guide the occupation surrounding the CU and the adoption of measures for the recovery of the same.
