Soybean farming has brought economic development to parts of South America, as well as environmental hopes and concerns. A substantial hope resides in the decoupling of Brazil's agricultural sector from deforestation in the Amazon region, in which case expansive agriculture need not imply forest degradation. However, concerns have also been voiced about the potential indirect effects of agriculture. This article addresses these indirect effects for the case of the Brazilian Amazon since 2002. Our work finds that as much as thirty-two percent of deforestation, or the loss of more than 30,000 km 2 of Amazon forest, is attributable, indirectly, to Brazil's soybean sector. However, we also observe that the magnitude of the indirect impact of the agriculture sector on forest loss in the Amazon has declined markedly since 2006. We also find a shift in the underlying causes of indirect land use change in the Amazon, and suggest that land appreciation in agricultural regions has supplanted farm expansions as a source of indirect land use change. Our results are broadly congruent with recent work recognizing the success of policy changes in mitigating the impact of soybean expansion on forest loss in the Amazon. However, they also caution that the soybean sector may continue to incentivize land clearings through its impact on regional land markets. [ABSTRACT FROM AUTHOR]

The Brazilian state of Mato Grosso was a global deforestation hotspot in the early 2000s. Deforested land is used predominantly to produce meat for distal consumption either through cattle ranching or soya bean for livestock feed. Deforestation declined dramatically in the latter part of the decade through a combination of market forces, policies, enforcement and improved monitoring. This study assesses how representative the national-level drivers underlying Mato Grosso's export-oriented deforestation are in other tropical forest countries based on agricultural exports, commercial agriculture and urbanization. We also assess how pervasive the governance and technical monitoring capacity that enabled Mato Grosso's decline in deforestation is in other countries. We find that between 41 and 54 per cent of 2000-2005 deforestation in tropical forest countries (other than Brazil) occurred in countries with drivers similar to Brazil. Very few countries had national-level governance and capacity similar to Brazil. Results suggest that the ecological, hydrological and social consequences of land-use change for export-oriented agriculture as discussed in this Theme Issue were applicable in about one-third of all tropical forest countries in 2000-2005. However, the feasibility of replicating Mato Grosso's success with controlling deforestation is more limited. Production landscapes to support distal consumption similar to Mato Grosso are likely to become more prevalent and are unlikely to follow a land-use transition model with increasing forest cover.

This article deploys the 'Theater of Cruelty,' articulated by the French surrealist Antonin Artaud, as a conceptual heuristic to explicate the empirical world of contemporary Amazonia, in particular the 'South of Para,' a site of land war and forest destruction, which the Theater of Cruelty posits as a single dramatic event. We pursue this explication via direct physical immersion, in the form of a travelogue following State Road PA-150 from Maraba to Eldorado dos Carajas, the scene of a massacre of nineteen land reform activists, shot down by Brazilian military police in collusion with the landed elite in 1996. Along the way, we have occasion to encounter the land reform movements and the forces of repression, which we depict both descriptively and theoretically, using our field trip as a point of departure for philosophical elaboration. To this end, we activate Artaud's 'Theater of Cruelty' to disclose the nature of violent conflict in the region. We suggest that theater, more generally, provides structure for cruel performance, and that violent land conflict, together with forest destruction, constitutes a predictable tragedy of theatrical events. In other words, violent land conflict in Amazonia, with all its terrible implications for people and environment, can be grasped as a theatrical structure, with philosophic and material consequences for mind and body. Thus, we articulate the development discourse of Amazonia as a violent, existential game, not a narrative of disembodied forces. [ABSTRACT FROM AUTHOR]

The global demand for different land-use practice commodities in the Amazonia is growing, and this region is increasingly affected by the impacts of land management. The aim of this study was to evaluate the influence of land-use intensification on soil spider assemblages from six different land-use systems in Colombia and Brazil. The systems were fallows after crops and pastures, forest, crops, pastures and plantations. Spider species richness and density decreased with increasing farming management intensity. A principal component analysis (PCA) showed forests and fallows were separated from systems with stronger anthropogenic soil disturbance. The relationships of ten spider guilds differed significantly between land-uses, suggesting that they can be a reliable parameter for studies of ecological indicators. [ABSTRACT FROM AUTHOR]
