“…This was extinct after the purchase of small properties by grain producers, and the communities of Jenipapo and Boa Esperança were seriously affected by these activities. All of them are located in the municipality of Belterra (Coelho 2009;Assis 2010). This is one of the consequences of the coexistence of unequal societies, where those with lower purchasing power and political strength suffer under the power of capital.…”

Rural landscapes and agrarian spaces under soybean expansion dynamics: a case study of the Santarém region, Brazilian Amazonia

Following the boom of soybean production from 2000 to 2006 in the Santarém region of the Brazilian Amazon, the mechanized agricultural area remained stable, unlike other regions. Deforestation was controlled, but this initial expansion led to the restructuring of the agrarian space in the region. Given this scenario, we aimed to understand the mechanized agricultural expansion effects in the region by comparing the periods 1999–2007 and 2007–2015. Our hypothesis was that it impacted heterogeneous actors and land tenure categories. We combined multi-temporal land change maps derived from remote sensing to land tenure information to evaluate how land change transitions differed over time, both in public (traditional and sustainable use official settlements) and private areas. In private areas, we observed a 12% reduction in forest cover in 1999–2007 and a 2.5% reduction in 2007–2015. In sustainable use settlements, forest loss was only 3% and 2% in each period, respectively. Mechanized agriculture occupied areas of family farming (42%), secondary vegetation (20%), pasture (20%), and forest areas (18%). Family farming lost most of the area to other uses. Within settlements, the area of family farming increased by 50% at the expense of the forest area. We conclude that the rise and fall of deforestation in the Brazilian Amazon hide multiple social and territorial processes. Understanding such dynamics is critical for establishing measures toward a sustainable future.

“…It was noted earlier that the model considers "production" of land endogenous to establishments, so it is as if establishments were putting into operation lands acquired at another time. However it turns out that the land market, despite the close relationship with the agricultural economy in the region (Costa, 2010), reacts to determinations of other planes, spheres and scales of economy, including urban and rural speculation (Reydon et al, 2006;Reydon and Souza, 2012), so that actual deforestation may be associated with the immediate process of "land production", and not necessarily with the needs of "rural production".…”

Development of regulations limiting greenhouse gas emissions is creating demands and new markets for land-based carbon sinks. Expectations of development of clean technologies and new sources of clean energy are affecting the supply side, creating opportunities for remuneration for sustainable development of natural resources. This paper [1] presents a model developed to gain a realistic understanding of the heterogeneous roles of capoeira (fallow agricultural land) in land use dynamics and CO 2 balance in the Brazilian Amazon. The model estimates the areas and CO 2 balance of different types of capoeira in association with different farming activities and also monitors carbon intensity over time in the context of technological trajectories (distinct farming systems). Modeling with agricultural census data compared six different, competing technological trajectories of capoeira for changes in major land use variables and impacts on CO 2 balance from 1990 to 2011. Results revealed that: a) technological trajectories contribute differently to net emissions of CO 2 , with livestock for meat enterprises being the highest net emitters and peasant agroforestry and plantation enterprises the lower emitters; b) carbon intensity tends to diminish over time because of increased weight of trajectories with lower carbon intensity, in combination with reduced carbon intensity of trajectories with higher carbon intensity; and c) for most trajectories, reuse of "old land" becomes increasingly more important for explaining the essence of agricultural dynamics, including CO 2 balance, than is deforestation for opening up new agricultural land. These results draw attention to the role of capoeiras in modernization and intensification of the agricultural sector through renovation of deforested land. The model allows evaluation of deforestation and CO 2 emissions as functions of the evolution of markets for agricultural products and of deforestation dynamics decoupled from those market fluctuations. The model points to the land market as a possible hypothetical determinant of deforestation; and has possible applications to development policies targeting the Brazilian Amazon.

Mercado, política e cultura na “baixa” Amazônia: circuitos longos e curtos

O artigo discute os circuitos culturais presentes no espaço da “baixa”Amazônia – a área de ocupação ocidental mais consolidada da região – tendo por referência três grupos populacionais, compreendidos enquanto trajetórias sociais, que se diferenciam, entre si, por seu modo de ocupação econômica e cultural do espaço. Observa-se como duas dessas trajetórias sociais participam mais ativamente dos circuitos culturais, enquanto a terceira mostra-se mais reservada em relação a eles. Procura-se interpretar essas relações de aproximação e distanciamento a partir da experiência social intersubjetiva que os envolve.
