Rising temperatures put 30 pct of coffee land at risk Scientists trying to help farmers adapt By Sarah Grainger Reuters May 19, 2010 SAN LUCAS TOLIMAN, Guatemala - Mexico and Central America could lose around a third of land suitable to grow coffee as global warming hurts conditions for the best quality beans, a study of regional farms shows. Specialty arabica coffee, the pride of countries like Guatemala, grows inside a very narrow band of altitude and temperature making it particularly sensitive to small changes in the climate. At the current rate temperatures are rising, there could be at least a 30 percent net loss in land suitable to farm coffee in Mexico and Central America by 2050 forcing many farmers to turn to different crops, said Peter Laderach, a lead researcher at the International Center for Tropical Agriculture.
