In Costa Rica, coffee growers have been forced to plant at higher and higher altitudes in recent years; this fall’s crop in Columbia is expected to be down substantially due to heavy rainfall. July’s harvest was down by nearly a third compared to last year. Brazil, the world’s largest producer of coffee, is expected to lose 10 percent of land used for coffee by 2010, and a third by 2070, as higher altitudes are required for successful growth. Coffee futures, traded in New York, have risen 19 percent due to the volatility.
