Coffee Production Put At Risk By Two Of Its Main Contributors

Coffee Production Put At Risk By Two Of Its Main Contributors”

But climate change is threatening both pollinators and the areas where coffee can grow.

"Coffee is one of the most valuable commodities on Earth, and needs a suitable climate and pollinating bees to produce well", said study co-author Taylor Ricketts, director of the University of Vermont's Gund Institute for Environment.

"We can think about...making sure we grow coffee in really smart ways, in ways that are more biodiversity friendly and ways that produce higher quality coffee in sufficient amounts on smaller amounts of land", said Ricketts.

Climate change is threatening the Latin American zones most favorable for growing coffee, according to a study out Monday that warns production could drop by almost 90 percent by 2050.

Major media reports, including newspapers such as the New York Times, linked coffee leaf rust-also known as CLR or roya-with climate change, but the scientists found "no evidence" for this, leading them to "reject the climate change hypothesis".

"These are all individual species that happened to co-occur now", Ricketts says, but they each have different tolerances to heat.

It may also be possible to develop varieties of coffee that are more heat tolerant.

The study, published today in the Proceedings of the National Academy of Sciences, is the first to analyze the coupled effects of climate change on coffee and bees at the national or continental level.

Using computer models, they found that it was a bit of both.

Based on the study findings, Venezuela, Nicaragua, and Honduras will likely experience a greater loss in their coffee regions than previously estimated.

Approximately 91 percent of Latin America's most fertile areas for coffee production are now less than 1.2 miles (1.9 kilometers) from a rainforest.

The scientists projected a slight increase in coffee suitability in Mexico, Guatemala, Colombia and Costa Rica, mainly in mountainous areas where temperatures are expectedto support coffee growing and more robust bee populations.

"We're going to lose a lot and not gain too much", he says.

This is not the first time that coffee production has been scrutinized by climate alarmists with dire predictions of future doom.

Pollinators such as bees play a vital role in the production of beans that end us as our morning cup of coffee.

"There's more at stake here than my nice espresso in NY or Paris going to get more expensive". Last November, the online journal Business Insider ran a scare piece titled "7 foods that could go extinct thanks to climate change", which threatened that global warming is "endangering some of the most popular and delicious foods on the planet".

Focus on maintaining habitats for wild bees in coffee-growing areas, especially those that are new due to climate change.
