    The parts of the suitable world for the cultivation of coffee, cashews and avocados will dramatically change as the world heats up, according to a new study.

    Key coffee regions in Brazil, Indonesia, Vietnam and Colombia All "will drastically decrease" at around 50% by 2050.

    Adequate areas for cashews and avocados will increase, but most will be far from current production sites.

    The authors say that greater efforts should be made to help farmers adapt.

    and thanks to the growing preferences of Consumers in richer countries, the demand for avocados and cashews have increased substantially in recent decades.

    While the threat to coffee change coffee has been well documented in recent years, there is little information on how growing temperatures will affect avocados and Anacarks

    In this study, the authors analyzed how the growing temperatures and changing precipitation rates will affect the three crops in the next 30 years. Researchers also have, for the first time, incorporate information about the characteristics of the land and soil.

    coffee is the most susceptible culture at high temperatures. In those countries that account for the majority of world production of Arabica, the variety of dominant coffee, the suitability for cultivation growth will decrease by half 2050, a "drastic" reduction, according to the report. Some key areas will see a heavier impact. In the lowest temperature scenario, there would be a reduction of 76% in the most suitable areas for Brazil's coffee. In Colombia it would be reduced by 63%.

    Some regions at the ends of the North and South of today's growth areas will be more appropriate, including Argentina, South Africa, China and New Zealand, among others. Image source, Getty ImageImage title, Facebook Cafeteria The greatest challenges of growing temperatures

    but followiment of the authors, this does not mean that these new regions can easily replace The current sites.

    "The key message for those who are in today's main producing regions is that agriculture systems have to adapt to changing conditions", He said the author of Lead Roman Grüter, from the University of Applied Sciences of Zurich. It does not mean you get perfect coffee growing regions within 10 years. "

    for cashews, the image is different. In general, the areas of the world that are highly their.
