Resumo
The Brazilian Savannah (Cerrado) is the second Brazilian Biome in area of conservation units (CU), a protection strategy to face the intense conversion to land use. These units are benefited by national environment policies that have been promulgated in the last few decades. However, many of these CU do not receive suitable effort to enhance their effectiveness. At the same time, the pressure of land use conversion in their surroundings also affects their effectiveness. This research proposes evaluates the relationship of spatial structure and spatial distribution of Federal and State Conservation Units in the Brazilian Savannah to the conversion of changes in land use that occurred over the last five decades. As a main result a thematic mapping of time-space distribution of CU is proposed. To archive this objective, a quantitative analysis of temporal and spatial distribution of UC is carried out as well as the evaluation of the representativeness of each phytophysiognomy in the CU facing the land use conversion. The database applied were obtained from government agencies. The Results revealed that considerable part of the protected areas are located in places inappropriate for agribusiness, while so-called areas more "enjoyable" have already been converted. The distribution of UC in the Cerrado is not regular, some focus on certain areas, while in others there are big gaps. In General, the largest UC are located at least anthropic of Cerrado and have recent creation, from the Decade of 1980. The East portion, are older, are in better fitness, agricultural area larger and present significant conflict of use in your interior. Ten main UC-compartments are identified in the Cerrado, proving that time and space are important variables to understand the role played by conservation policies in the Brazilian Savannah. Protected areas constitute an alternative for conservation, however you must think your location and connection, so that they can ensure the maintenance of ecosystems and are in fact effective.
