Recently, according tomedia reports, in the next 30 years, due to rising temperatures, increased pests and diseases, coffee may disappear. Rising temperatures are the main threat to coffee plantations, and many coffee tree farmers in the UK have given up growing coffee because of rising prices for coffee trees, the report said. It is understood that the reason for the price increase is the decline of coffee plants.
To that end, experts have asked companies to invest more to help coffee growers buy new tools and plants so they can continue to grow coffee. In addition, pests and diseases have led to declining coffee bean production, the biggest threat being coffee rust.
When the leaves of the diseased plant are scratched, they produce a small brown powder similar to iron oxide. This disease caused by coffee camel spores also changes the color of the leaves from bright green to brownish, eventually depriving the diseased plant of all leaves from bean.
At the end of the 19th century, Southeast Asian countries such as Sri Lanka and the Philippines were the world’s leading coffee exporters, but their coffee bean production declined sharply in the following decades due to the rust of coffee.
Now a growing number of alabika bean farmers are abandoning the world’s best-selling coffee variety in favour of crops such as sugar cane.
At present, coffee is mainly produced in tropical countries near the equator, including Brazil, Colombia, Vietnam, Indonesia, etc.
Experts worry that these countries may no longer be fit to grow coffee beans as warmer temperatures rise. By 2050, the land currently suitable for coffee cultivation will gradually disappear.
