A multi-disciplinary team of authors analyze the economics of Brazilian deforestation using a large data set of ecological and economic variables. They survey the most up to date work in this field and present their own dynamic and spatial econometric analysis based on municipality level panel data spanning the entire Brazilian Amazon from 1970 to 1996. By observing the dynamics of land use change over such a long period the team is able to provide quantitative estimates of the long-run economic costs and benefits of both land clearing and government policies such as road building. The authors find that some government policies, such as road paving in already highly settled areas, are beneficial both for economic development and for the preservation of forest, while other policies, such as the construction of unpaved roads through virgin areas, stimulate wasteful land uses to the detriment of both economic growth and forest cover.
Understanding the impact of road investments on deforestation is part of a complete evaluation of the expansion of infrastructure for development. We find evidence of spatial spillovers from roads in the Brazilian Amazon: deforestation "rises" in the census tracts that lack roads but are in the same county as and within 100 km of a tract with a new paved or unpaved road. At greater distances from the new roads the evidence is mixed, including negative coefficients of inconsistent significance between 100 and 300 km, and if anything, higher neighbor deforestation at distances over 300 km.

Abstract:The recent growth of soybean cultivation in the Brazilian Amazon has been unprecedented, even as the debate continues over its economic and environmental consequences. Based on contemporary datasets as well as our own field studies, this paper examines the social and economic costs and benefits of increases in soybean production for local populations. After presenting some background information on the rise of soybean cultivation in Brazil we examine the relationship between increases in soybean production and local economic indicators. We find that increased soy production both reduces poverty indicators and raises median rural incomes. However, we also note that this increase is associated with increased measures of inequality, and we consider the wider political and social consequences of this connection in our qualitative fieldwork. The mixed--method approach helps shed light not only economic effects of soy cultivation but also on the more complex social and political context that is, arguably, even more policy--relevant.
This paper examines the effects of the Brazilian governments' title granting policies on the efficiency of agricultural and timber production in the Brazilian Amazon. A two-stage procedure is used that combines Data Envelopment Analysis (DEA) and a Tobit regression. Provision of private land titles before 1995 is found to positively affect the technical efficiency of agricultural and joint agriculture–timber production in 1995. Governmental expenditures, including expenditures to secure property rights, also are found to increase technical efficiency in the agricultural industry. The analysis indicates that revenue efficiency can be improved by producing more roundwood and less agricultural product. Land-granting policies may favorably affect environmental conservation by intensifying land use in agriculture, but they also may harm development by discouraging timber production.
