According to a new study, as the world warms, the areas suitable for growing coffee, cashews, and avocados will change greatly. By 2050, significant coffee-producing regions in Brazil, Indonesia, Vietnam, and Colombia would have “dramatically decreased.” Although most will be far from present production zones, the number of viable regions for cashews and avocados will increase. Coffee is one of the most important crops in the world, serving as a source of income for millions of small farmers as well as a beverage.

Due to changing consumer preferences in wealthier countries, avocado and cashew consumption has risen considerably in recent decades. While the threat of climate change to coffee has gotten a lot of press in recent years, less is known about how rising temperatures would affect avocados and cashews. Over the next 30 years, the authors of this study looked at how rising temperatures and changing precipitation rates will affect the three crops. The researchers have added information about land and soil qualities for the first time. Coffee is the crop that is most susceptible to high temperatures. The suitability for growing Arabica – the world’s most popular coffee variety – would reduce by half by 2050 in the countries that produce the majority of the world’s Arabica, according to the study.
