“…The Bank of Brazil and the National Rural Credit System were established to provide cheap credit to farmers, with interest rates fixed below the rate of inflation (Warnken 1999;Sousa and Busch 1998). In the Cerrado, the government created the Superintendency of the Development of the Center-West (SUDECO) to implement fiscal incentives for migration, the Development Program for the Cerrado (POLOCENTRO) to fund agricultural research and extension, improvements to roads and electricity infrastructure, and the Japanese-Brazilian Cooperative Program for Cerrado Development (PRODECER) to subsidize the construction and purchase of silos and farm equipment (Jepson, Brannstrom, and Filippi 2010;Fearnside 2001;Jepson 2006a). More broadly, the government also provided minimum price supports for commodities such as soy, corn and wheat (Damico and Nassar 2007), but high global prices have rendered these price supports largely unnecessary in recent years.…”

In this study we assess the sustainability of the Brazilian soy industry over the past 40 years in comparison to alternative land uses. We conclude that Brazilian soy production performs as well as or better than sugarcane or cattle production in a number of areas, including macroeconomic contributions, local economic development and land use efficiency, though it involves similar tradeoffs between growth and equity, and food production and conservation. While there is no evidence that soy has reduced food security in Brazil, tax redistributions and value-added activities from soy remain limited, particularly in comparison to sugarcane production. Emerging environmental governance measures have helped to reduce the land cover impacts from soy; however, little effort has been taken to minimize the impacts of intensification.

“…Images were also corrected for atmospheric and radiometric errors in ENVI 4.5. A root mean square error less than 3 meters in each case ensured that changes between the two dates resulted from actual land-use change, and not from uneven image registration [61,63,64].…”

Abstract:Recently, the call to combine land change science (LCS) and political ecology (PE) in the study of human-environment interactions has been widely discussed by scientists from both subfields of geography. In this paper, we use a hybrid ecology framework to examine the effects of conservation policies on the environment and the livelihood of the people of the Korup National Park (KNP). Using techniques in both PE and LCS, our results show that conservation policies, politics, and population are the primary drivers of environmental change in the KNP. We conclude by arguing that a deeper understanding can be garnered by combining LCS and PE approaches to analyze and contribute to the people and parks debate.

“…No aspecto ambiental, a conversão do uso da terra representa uma consequência mais aparente (Jepson et al, 2010), de modo que o bioma apresenta-se como a ecorregião brasileira com as maiores taxas de alterações de seus ambientes naturais (Martins-Júnior e Chaves, 2008), ou seja, mais da metade da vegetação original foi convertida em pastagens, culturas anuais e outras formas de cobertura e uso da terra (Sano et al, 2008). Por outro lado, e tendo por base a análise integrada de dados de diferentes naturezas, constatam-se transformações estruturais que ocorreram nos espaços agrários (Balsan, 2006), a exemplo da organização espacial das propriedades rurais, as quais foram influenciadas por condições edafoclimáticas, privilegiando áreas com boas características físicas de solo, relevo (Rezende, 2002), e índices pluviométricos favoráveis ao desenvolvimento das principais commodities implantadas pelo setor produtivo (Vilela et al, 2011).…”

RESUMOO presente trabalho, ao utilizar a bacia hidrográfica do rio Vermelho como unidade experimental do bioma Cerrado, teve como objetivo principal realizar uma análise ampla das respostas biofísicas, frente aos processos históricos que condicionaram as transformações na paisagem, considerando o período entre 2001 a 2011 e uma ampla base de dados satelitária. Algumas características edáficas, à exemplo de solos e relevo, foram fatores determinantes na organização espacial da paisagem. Fatores climáticos, à exemplo da sazonalidade, tem uma influência direta na biomassa das principais formações vegetais, principalmente àquelas que apresentam sistemas radiculares superficiais (ex. pastagens cultivadas), com reduções nos valores dos índices de vegetação de até 50 % durante o período de seca, a partir da observação e correlação comprovada entre os valores de P e EVI. De forma significativa, as áreas de vegetação natural, comparadas às áreas de pastagens cultivadas, apresentaram comportamentos distintos do ponto de vista biofísico (p < 0,05). Em fato, dois macroambientes puderam ser definidos para a área de estudo, i.e. "Região 1" e "Região 2", onde predominam a ocupação antrópica e a vegetação natural remanescente, respectivamente.Palavras chave: Dinâmica da Paisagem, Sensoriamento Remoto, Parâmetros Biofísicos.
