LONDON Global warming poses a threat to future world coffee crops with rising temperatures and drought likely to force some producers to seek higher and cooler land, according to a report issued by analyst F.O. Licht.
"Few now doubt that global warming is going to present the world's coffee growers with a big challenge in the years to come," an article in Licht's International Coffee Report said.
It noted a United Nations Environment Program research project in Uganda, for instance, had concluded that a rise in temperatures of about 2 degrees Celsius would mean a "dramatic" reduction in the coffee growing area with producers moving to higher regions where there is less suitable land.
In India's Coorg coffee region, rising temperatures and reduced rainfall would have a detrimental impact due to a drop in the number of bees to fertilize the trees and an increased threat from a destructive pest, white stem borer, it added.
"Whether or not some coffee regions eventually fade away is anyone's guess, but one thing is certain -- coffee farmers by and large are a tenacious breed because often enough they have no other viable sources of earning a living," the report said.
