The Future of Coffee Growing Land

New research from Switzerland brings new evidence to the conversation about the land coffee is grown on—the study found that climate change will reduce land suitable for growing coffee by 50% by 2050.

Specifically, the researchers’ analysis found that land with the best suitability for coffee growing in the world’s five largest coffee-growing countries will be reduced by 50% by climate change under all scenarios. Moderately suitable land will be reduced by more than 30%.

The new study repeats, almost exactly, the warning a 2014 study made, that lands for growing coffee will be cut in half by the middle of the new century. This is a serious warning about the sustainability of the coffee industry.

The study comes from Zurich University of Applied Sciences. It was led by Roman Gruter. The study used data from fourteen global climate models and three scenarios of future emission predictions. It estimated the effects on the land and soil for crops. It considered things like slop, texture and pH.

The study also looked at the future land availability for crops like avocados and cashews. However, the study found that coffee lands happen to be in the most danger from climate change.


A New Meta-Review of Coffee and Prostate Cancer

A new meta-study (a study which collects and analyzes the data of many other studies) as found association between daily coffee drinking and decreased risk of prostate cancer.

While this info isn’t completely new, this latest review looked at 16 different studies which included between the 16 over a million patients to determine whether or not coffee drinking might really reduce the risk of developing prostate cancer.

While the meta-study cannot say why it is so, the study found the highest levels of coffee drinking were correlated with a 9% decres in the risk of prostate cancer when compared to the lowest levels of consumption.

The study authors make some educated guesses as to the reasons behind this. They stated Coffee improves glucose metabolism, decreases concentrations of plasma insulin and insulin-like growth factor-1, has anti-inflammatory and antioxidant effects, and affects sex hormone levels, all of which may play roles in the initiation, development, and progression of prostate cancer.”

Another interesting item found in the meta-review, according to its authors. Is that the more coffee you drink the lower you chances of developing prostate cancer: the rate is 1% less risk for each daily cup.

However, extreme coffee consumption is not recommended.
