Since 1984, nearly 1,000 people have been killed in the Brazilian Amazon due to land conflicts stemming from unequal distribution of land, land tenure insecurity, and lawlessness. During this same period, the region experienced almost complete deforestation (< 8% forest cover by 2010). Land conflict exacts a human toll, but it also affects agents' decisions about land use, the subject of this article. Using a property-level panel dataset covering the period of redemocratization in Brazil (1984) until the privatization of long-term leases in the Eastern Amazon (2010), we show that deforestation is affected by land conflict, particularly in cases of expropriation of property for agrarian reform settlement formation and when that conflict involves fatalities. Deforestation on agrarian reform settlements is much greater when soils are poor for agriculture and when the land has been the object of past conflict. Deforestation and conflict are episodic, and both agronomic drivers and contentious drivers of land change are active in the region. Ultimately, the outcome of these processes of contentious and agronomic land change is substantial deforestation, regardless of who was in possession and control of the land. [ABSTRACT FROM AUTHOR]

This article considers Amazonian environmental change by focusing on political and economic processes in a place-specific context with far-reaching global implications. In particular, we consider the destruction of the Brazil nut forest (BNF) in the lower basin. The Brazil nut tree yields a valuable nontimber forest product, and its loss raises concerns about Amazonia's agro-ecological sustainability. The article posits the destruction of the BNF as an outcome of land creation, the transformation of soil surfaces into a production factor for market-oriented agriculture. Land creation in the lower basin sparked violent conflict, with the destruction of the BNF as collateral damage. Our account complements earlier research on the political economy of Amazonian development by providing an update tuned to the institutional and economic changes that have led to the region's engagement with globalized beef markets and to the transformative impact on implicated actors (i.e., peasant, capital, and the state). In addition, the article uses the BNF case to consider current threats to Amazonia. In Brazil, deforestation rates declined after the turn of the millennium, due to environmental policy. Recent numbers show deforestation on the rise, however, as South American nations fast-track large infrastructure projects to transform Amazonia into a transport hub and a continental source of hydropower. The article questions whether Brazil's environmental policies will sustain the Amazonian forest over the long run; the BNF disappeared despite efforts at conservation buttressed by legislative action. The article uses data from surveys, remote sensing, regional newspapers, and secondary sources based on declassified documents from Brazil's Armed Forces, the National Truth Commission, and the Central Intelligence Agency (CIA).

This article implements a spatially explicit model to estimate the probability of forest and agricultural fires in the Brazilian Amazon. We innovate by using variables that reflect farm-gate prices of beef and soy, and also provide a conceptual model of field management and deforestation fires to simulate the impact of road-paving, cattle exports, and conservation area designation on the occurrence of fire. Our analysis shows that fire is positively correlated with the price of beef and soy, and that the creation of new conservation units may offset the negative environmental impacts caused by the increasing number of fire events associated with early stages of frontier development.
