Climate change threatens the future of coffee, cashews and avocados.
The regions most suitable for their growth may undergo radical changes with the warming of the planet due to the climate crisis. Scientists from the University of Zurich in Switzerland say that research has shown that the conditions for growing Arabica coffee, the dominant type of coffee on the market, in most of the regions that produce it, are no longer what they used to be.
The new study may be of key importance to some economies and their livelihoods, as it may take many years of cultivating these crops to achieve a sustainable yield. So for an avocado tree to bear fruit, it takes at least eight years, while in a colder climate, it takes 20 years.
To examine how the climate and growth conditions for these crops may change over the next 30 years, the researchers combined climate forecasts with soil-influencing factors to model and predict as accurately as appropriate how appropriate they would be. various regions around the world to grow coffee or avocados by 2050.
Coffee turns out to be the most sensitive, with a worrying decline in suitability in all of its major producing regions, including Brazil, Vietnam, Indonesia and Colombia.
