Indicadores ambientais para áreas de preservação permanente Environmental indicators for areas of permanent preservation

Abstract

Apesar da conscientização pelas questões ambientais, existe uma crescente pressão sobre os recursos naturais. A análise do uso e da ocupação das terras é um ponto de partida para adequação do ambiente antrópico cuja capacidade de suporte é, portanto, fundamental para a criação de modelos de gestão. O trabalho trata de uma pesquisa que utiliza o geoprocessamento e a gestão de informações do uso e ocupação para estudos ambientais. O objetivo foi selecionar indicadores para gestão das Áreas de Preservação Permanente (APP) e aprimoramento do uso de informações para gestão ambiental. O estudo foi realizado na bacia hidrográfica do rio Jundiaí-Mirim, Jundiaí, SP; utilizaram-se os dados de um levantamento prévio das suas condições ambientais. A técnica empregada permitiu a seleção de oito indicadores que se mostraram capazes de caracterizar o estado das áreas avaliadas. Os resultados obtidos mostraram que somente 44,6% da APP se encontram em conformidade com a legislação.Despite awareness of environmental issues, there is a growing human pressure on natural resources. The analysis of the land use can be considered as a starting point for studies of anthropogenic environmental adjustment and it is essential to propose models of management with emphasis on land sustainability. The work consists of a research conducted on environmental studies, using GIS and information management of land use. The goal was to select environmental indicators for management of Permanent Preservation Areas (APP), where eight indicators were selected. The study was carried out in the Jundiaí-Mirim watershed, in the State of São Paulo, Brazil. The technique allowed the selection of eight indicators that were able to characterize the state of the evaluated areas. The results showed that only 44.6% of APP are in accordance with the law.
