| === Description === | |
| |
| The Brazilian Amazon rainforest is a largely diverse region, in which subregions with different rates of change coexist, due the diversity of accessibility, ecological, socioeconomic and political conditions. In recent decades deforestation has prevailed owing mostly to private investments in agricultural expansion, associated with large-scale cattle ranching, small-scale subsistence farming and soybeans expansion. Deforestation rates changed from 1988 to 2007, the total deforested area in the region varied from about 11,000 sq km to more than 29,000 sq km a year. In 2004, the estimated rate dropped to 27,379 sq km, and in 2007 to 11,224 sq km. The lower rates since 2005 have been associated to control actions conducted by the Brazilian government, including law enforcement actions and the creation of protected areas, and partly to lower commodities prices in the international market. However, there is an expectation that rates may start to rise again in the period of 2008-2010, due to rise in the commodities prices and the expansion of biofuel. Therefore, the objective of this work is to understand the intraregional distribution of deforestation rates, using quantitative methods to evaluate the possible impacts of alternative policies and decision making processes. The hypotheses of this work are: (A) the current hotspots of deforestation contributed differently to deforestation rates variation, as they responded to market and policy conditions according to their specific socioeconomic context; and (B) localized deforestation control policies applied to one municipality, such as the creation of protected areas or localized law enforcement actions, might stimulate the occupation of other areas in the medium and long run. This proposal adds to previous works increasing the knowledge about the last decade deforestation rates variation, exploring the intraregional multiscale interactions of distinct socioeconomic and political contexts. | |
