The greenhouse effect reduces food production

Global agricultural output will fall sharply as global temperatures rise, making food shortages in the poorest countries worse, experts warn.

"Climate change is not a future event. It is happening right now," said Cynthia Rosenzweig, a scientist at the US Aerospace Agency (NASA), speaking at a conference. International agriculture in Washington (USA) on December 4. Scientists from 15 agricultural research centers around the world attended the seminar.

According to agricultural experts, droughts will occur more in countries like Tanzania and Mozambique, floods will occur more in coastal areas of countries like Bangladesh, and reduce agricultural productivity in countries. like Colombia when the earth's temperature rises.

The impact of global warming on farmers will take place differently, said Robert Zeigler, general director of the International Rice Research Institute in the Philippines. It may increase potato production in the northern hemisphere, but it has the opposite effect in Africa, East Asia, South Asia and South America - where potatoes are an important food crop.

Experts say that it is necessary to create salt-tolerant plants and warm weather. The management method suitable for the new climate situation, including the use of more efficient water sources, may also help reduce the damage caused by the greenhouse effect.
