摘要
The Amazon continues to lose its natural vegetation, and Brazil, in particular, has a distinct agricultural frontier. We highlight the role of surveillance in reducing deforestation rates in the region. This paper lists the characteristics of the current agrarian structure and the surveillance information from Brazilian Institute of Environment and Natural Resources (IBAMA) with the current deforestation standards in the Amazonian municipalities. In addition, we investigate the relationship between the new areas of deforestation and the low level of agrarian technology in those areas. To do this, we used public deforestation data from the second half of the last decade (2005-2009). We also used agricultural census data to create an index of level of agrarian technology. Based on level of agrarian technology index it was possible to conclude that areas where agriculture and livestock have low level of agrarian technology coincide with the areas of highest deforestation in the Amazon. We found that agrarian structure guided the Amazonian deforestation at the end of this decade, as in previous decades. The maintenance of Agrarian structure in the region over the past 10 years makes us hypothesize that factors such as surveillance may determine decreases in deforestation rates. We showed that embargoed areas due to illegal deforestation occur in the critical areas of deforestation in Amazon, although do not get a clear any decrease in those deforestation rates caused by it. Possibly due to the time lag between recent changes in IBAMA surveillance approach and the society perception of the costs associated to illegal deforestation.
