Within a few decades the Arabica coffee it may have become extinct due to the pressing global warming. There are still those who did not believe in climate changes, further proof of the dramatic phenomenon comes from the researchers of the Kew Gardens. In the next 70 years, the increase in global temperatures could make 99.7% of the areas suitable for the cultivation of Arabica coffee no longer suitable for this purpose.

The manufacturing companies of Coffee they should “migrate” their 50-meter plantations for every decade. Companies could install artificial cooling systems, increase irrigation or rely on GMOs, however, the species Arabicawild”Has a genetic diversity that makes it particularly resistant to threats such as pests and plant diseases.

THE climate changes they will force coffee companies to identify new plantation sites; according to the researchers, the migration of coffee plantations is the only way to preserve the species Arabica which will no longer be cultivated in its areas of origin (the mountains of Ethiopia and southern Sudan) but elsewhere. L'Arabica it is the most widespread quality of coffee on the global market. It represents 70% of the best-selling coffees in the United States and in most of Europe, including Italy. Only in Greece and Turkey is Arabica not the most popular coffee because the beans of Robust, less common in Italy due to its high caffeine content which makes it less pleasant on the palate.

L'Arabica could become extinct by 2080. The new study, published by the journal Public Library of Science ONE, analyzed various scenarios based on the probabilities and trends of climate changes. In the best prospect at least 65% of the area destined for Arabica plantations will no longer be suitable by 2080, in the worst scenario the loss of 100% of the area is expected. In some areas such as in the Regions of Platau Boma in South Sudan, the end of plantations could occur as early as 2020.

The study exclusively examined the Arabica species in response to the increase in temperature. Despite the drama of the predictions, the researchers say their estimates are "optimistic"Because they have not taken into account the deforestation, a pressing phenomenon that is not sparing the plateaus where i coffee beans. Another factor ruled out was the likely decline in the number of seed-spreading birds. Both consequences of the global warming.
