More than half of the world’s 124 wild coffee plant species meet the criteria for inclusion on the International Union for Conservation of Nature’s Red List of Threatened Species, according to reports published today (January 16) in Science Advances and Global Change Biology. The authors say extinctions among the species would limit plant breeders’ options in developing new types of coffee in the future.
The study, carried out at Britain’s Royal Botanic Gardens, Kew, found that 60 percent of wild coffee species are at risk, a figure that “is extremely high, especially when you compare this to a global estimate of 22% for plants,” says coauthor Eimear Nic Lughadha in a statement. “Some of the coffee species assessed have not been seen in the wild for more than 100 years, and it is possible that some may already be extinct.”

A second study, in Global Change Biology, found that wild Arabica coffee can be classed as threatened under official (IUCN Red List) rankings, when climate change projections are taken into account.
Its natural population is likely to shrink by up to 50% or more by 2088 because of climate change alone, according to the research.
Wild Arabica is used to supply seeds for coffee farming and also as a harvested crop in its own right.
Ethiopia is the home of Arabica coffee, where it grows naturally in upland rainforests.
"Given the importance of Arabica coffee to Ethiopia, and to the world, we need to do our utmost to understand the risks facing its survival in the wild," said Dr Tadesse Woldemariam Gole, of the Environment and Coffee Forest Forum in Addis Ababa.

They say "oh Climate Change is so horrible!" I'll tell you, there is a cooling and there is a heating, and I mean, look, it used to not be Climate Change. It used to be Global Warming. Unless somebody can prove something to me, I believe there's weather. I believe there's change. And actually, we’ve had times where the weather wasn’t working out, so they changed it to extreme weather, and they have all different names, you know, so that it fits the bill. But the problem we have, and if you look at our energy costs, and all of the things that we’re doing to solve a problem that I don’t think in any major fashion exists. I mean, Obama thinks it’s the Number 1 problem of the world today. And I think it’s very low on the list. So I am not a believer, and I will, unless somebody can prove something to me, I believe there’s weather. I believe there’s change, and I believe it goes up and it goes down, and it goes up again. And it changes depending on years and centuries, but I am not a believer, and we have much bigger problems.
I don’t drink Coffee. I’ve never had a Coffee. That's one of my only good traits. And I’m not saying good or bad, some people like it. I just choose not to do that for a lot of reasons. I see so many people start on Coffee, it gets away from them. They can't control themselves. And they can't stop. It's very addictive. So if the Wild Coffee dies out, it's not the worst thing that can happen. And if you look into that one, it can be a good thing.
