Remittances and deforestation
A group of scientists have been looking at the intersection of economics, ecology, and emigration as it impacts the forest cover (or lack thereof) in El Salvador: A study in the September issue of BioScience presents novel findings on how globalization, land policy changes, and monies sent to family members by emigrants have transformed agriculture and stimulated woodland resurgence in El Salvador. The study, by Susanna B. Hecht and Sassan S. Saatchi, employed socioeconomic data, land-use surveys, and satellite imagery to monitor changes in woody cover in El Salvador since peace accords were signed in 1992. Most analyses of forest cover in Central America have focused on the loss of old-growth forests. In drawing attention to the regrowth of woodland in a country that was extensively deforested during the 1970s, Hecht and Saatchi call for a renewed examination of social and economic influences on agricultural practices and of the implications for forest extent. New-growth forests, ofte...
