Contribuição do cadastro ambiental rural na conservação de recursos naturais nos limites de duas bacias hidrográficas amazônicas

Abstract

The conversion from Forest to other kinds of alternative land uses has been occurred rapidly in the Amazon region. This process has been occurred mostly due to the development of the cattle ranching, large scale and familiar agriculture, commercial timber and mining. In this context, objecting to promote the conservation of natural resources, the Brazilian government adopted the system of protected areas, Indian lands and quilombo. And also to promote major environmental protection and conservation of resources, were created tools such as the Cadastro Ambiental Rural – CAR objecting to map and monitoring rural properties to comply with the disposed in the brazilian forestry code, considering mainly the legal reserve and the permanently protected areas. Thereby, this research tried to evaluate the capacity of such legal reserves to ensure the conservation of natural resources, making use of the CAR data and other products of governmental agencies researches. Two Amazon basins were evaluate through principles of landscape ecology with the use of landscape metrics. The results indicate that the two study areas have different characteristics, one having more capacity to maintain the resources and other markedly more fragmented, indicating also different characteristics of rural properties with different importance to the conservation of the natural resources.
