A cup of coffee may be a luxury in future and will be much more expensive. Before the end of the century, climate change will lead to the possible extinction of wild Arabica beans.
A study conducted by the scientists at the Royal Botanic Gardens, Kew,UK, in collaboration with scientists in Ethiopia found out that climate change will pose a threat to the genetic sustainability of the crop.
Although commercial coffee planters can still cultivate crop designed with the right conditions, the loss of wild Arabica will make the planters difficult to survive long-term and hit threats like pests and disease.
Wild Arabica is thought to be important for sustainability of the coffee as it has greater genetic diversity. Coffee is the second most-traded commodity in the world.
According to the scientists, 38 to 99.7% of the areas appropriate for wild Arabica will disappear by 2080. Coffee is a highly weather-dependent crop; the increase in the temperature in planting regions can put at risk the future of Arabica coffee and the livelihood of millions of people. The extinction will be a crucial economic problem for several countries.
The highlands of forests of Ethiopia and South Sudan are highly destroyed due to deforestation. Many other reasons including pests and diseases, changes in flowering times, and perhaps a reduction in the number of birds have also contributed to the negative impact.
