We summarize existing theoretical claims linking poverty to rates of deforestation and then examine this linkage empirically for Costa Rica during the 20th century using an econometric approach that addresses the irreversibilities in deforestation. Our data facilitate an empirical analysis of the implications for deforestation of where the poor live. Without controlling for this, impacts of poverty per se are confounded by richer areas being different from the areas inhabited by the poor, who we expect to find on more marginal lands, for instance less profitable lands.
We review claims about the potential for carbon markets that link both payments for carbon services and poverty levels to ongoing rates of tropical deforestation. We then examine these effects empirically for Costa Rica during the 20th century using an econometric approach that addresses the irreversibilities in deforestation. We find significant effects of the relative returns to forest on deforestation rates. Thus, carbon payments would induce conservation and also carbon sequestration, and if land users were poor could conserve forest while addressing rural poverty.
The second volume of Land Reform, Land Settlement and Cooperatives for 2004 comprises eight articles that examine a range of areas central to land tenure activity. They provide a stimulating and, in some cases, critical set of perspectives on how best to tackle some of these issues.
