"Global Land-Use Spillovers of Technological Progress in Agriculture" by Villoria, Nelson B. Abstract Economic theory suggests that increases in regional agricultural productivity can increase regional deforestation by raising the returns to agricultural land; meanwhile, it also suggests that the environmental damage from such regional deforestation may be offset as pressure on forests is relieved in other parts of the world. While there is plenty of evidence linking localized agricultural intensification to deforestation, the linkages between localized and global land use changes suggested by the theory remain unexplored. This lack of evidence has led some influential voices to question the use of agricultural research to achieve environmental outcomes. There remains, therefore a critical need to empirically identify the linkages between local technical change and global land savings. In the absence of such evidence, the debate on the appropriateness of agricultural intensification as a means to save forests will remain polarized and current cost-benefit analysis of programs to improve productivity will continue to fail to account for global supply responses, impeding the design of more efficient mechanisms to achieve the twin goals of increased agricultural output and forests protection. The objective of this paper, is to determine the global environmental effects from regional increases in agricultural productivity. Our central hypothesis is that increases in productivity in one region offset pressures on forest conversion to land use in other regions leading to global positive environmental benefits such as reduced carbon emissions from deforestation, which magnitude will depend on where in the world land savings occur. |
