Such deforestation has long been driven by farmers eking out a slash and burn living or loggers using new roads to cut inroads into pristine forest. But now new data appears to show that, at least for the first five years of the 21st century, big block clearings that reflect industrial deforestation have come to dominate, rather than smaller scale efforts that leave behind long, narrow swaths of cleared land. Geographer Ruth DeFries of Columbia University and her colleagues used satellite images from Landsat, along with the MODIS instrument on Aqua to analyze tree clearing in countries ringing the tropics, representing 98 percent of all remaining tropical forest. Instead of the typical "fish bone" signature of deforestation from small scale operations, large, chunky blocks of cleared land reveal a changing driver for cutting down woods: large enterprises feeding urban demand, according to a new paper published in Nature Geoscience on February 7. Scientific American is part of Nature Publishing Group. In fact, a statistical analysis of 41 countries revealed that forest loss rates are most closely linked with urban population growth and agricultural exports from 2000 to 2005even overall population growth was not as strong a driver. "In previous decades, deforestation was associated with planned colonization, resettlement schemes and local farmers clearing land to grow food for subsistence," DeFries says. "What we're seeing is a shift from small scale farmers driving deforestation to distant demands from urban growth, agricultural trade and exports being more important drivers. "In other words, the increasing urbanization of the developing worldas well as an ongoing increase in consumption in the developed world for products that have an impact on forests, whether furniture, shoe leather or chicken fed on soy mealis driving deforestation, rather than containing it, as populations leave rural areas to concentrate in booming cities. "One of the really striking characteristics of this century is urbanization and rapid urban growth in the developing world," DeFries says. ""People in cities need to eat.
