Across central America, even as rains arrive, many coffee plantations contain only spindly, nearly defoliated bushes, the result of a blight known as coffee leaf rust whose devastation, so far, has yet to affect the prices of premium highland coffee that baristas serve around the developed world.
But while Americans have yet to feel its effects, the blight may soon prove to be as disastrous as any earthquake or volcanic eruption to afflict central America.
Already, it’s knocked nearly half a million people out of work and driven up crime. And the crisis is only beginning. It may soon send a stream of new migrants toward the US, speed up deforestation and invigorate illicit narcotics production.
It also serves as a bellwether on climate change, which appears to be causing temperatures to rise, taking plagues and infestations to higher elevations that once were considered too cool and dry for the rust fungus.
At the San Pedrana Co-operative on the flanks of the Fuego Volcano southwest of Guatemala City, this country’s capital, Miguel Angel Xia turned over a leaf to display the orange, dust-like fungus that sucks nourishing sap from coffee leaves, killing the bushes.
“Rust has been around for 30 years,” Xia said. “But it was always at 3,000 feet or below. And now, it’s up to 5,000 feet. It never would’ve been this high before.”
“No one imagined that it could thrive in that environment and go airborne,” said Christian Wolthers, a past president of the Specialty Coffee Association of America who imports green coffee from his base in Fort Lauderdale, Fla.
Coffee rust has changed history in centuries past. The fungus blighted crops in the British colony of Ceylon in the 1870s, decimating coffee exports to London and helping turn the British into a nation of tea drinkers.
Since then, fungicides have kept coffee rust under control when it reappears.
But this time is different, experts say. The aggressive outbreak has extended to more than 70% of coffee bushes in Guatemala and El Salvador, 64% in Costa Rica, and lesser amounts in Nicaragua and Honduras, according to a May 13 report by the International Coffee Organisation.
Regional coffee production fell 17.1% in the past October-to-March season, and it is likely to fall 30% to 40% in the coming season, which begins in October.
In central America, with a total population of 41mn, nearly 1mn seasonal and permanent coffee workers are expected to lose their jobs next season.
“Each of these jobs are providing for six people. You do the math,” said Maja Wallengren, an independent coffee analyst based in Mexico City who predicts that the disruption to families will be far greater than just the economic costs.
“It’s not something you can get under control in a year.”
Other agricultural sectors, such as sugar and palm oil, cannot pick up the slack from unemployed coffee workers, and since devastated coffee farms are often clustered together, pockets of unemployment soar.
“You’re going to see a lot of migration,” said Alejandro Keller, who is the fourth generation of his family to grow coffee at the Finca Santa Isabel, a large organic farm an hour’s drive from Guatemala City.
