Because of global warming people lose coffee


A group of scientists representing the climate Institute in Sydney, came to the conclusion that climate change may lead to disappearance from the face of the Earth, wild coffee, and then coffee plantations. Already, global warming greatly affects the yield of coffee in many regions, experts say.

As an example, scientists lead the coffee plantations of Tanzania, which charges coffee fall by about 137 kilograms per hectare with each increase of 1 degree in the average temperature. According to experts, due to a relatively rapid warming in this region with the 60-ies of the last century, the productivity of coffee there is already halved.

The researchers note that the growth temperature in the regions where it grows coffee, not only makes the climate less “comfortable” for plants, but also provokes the invasion of various pests. As a result, in the coming decades on the planet may not be any wild coffee, is essential for maintaining genetic diversity “cultural” varieties. In combination with a reduction in the yield of plantations it may soon lead to the fact that coffee is expensive, and its taste will deteriorate. In the future, the problem will only be exacerbated.

The lower yields of coffee may not only leave many without a drink, but also directly affect the welfare of 120 million very poor people, which profit directly depends on the coffee industry, the researchers note.

The movement of plantations in the more distant from the equator, regions where future temperature can achieve perfect coffee indicators can not be considered fully effective solution of emerging problems, scientists say: according to them, in a new place, the plantation will take root only a few years that will require significant financial investments. Not less time and money will be needed and the introduction of new coffee varieties, adapted to changing conditions.
