Researchers say climate change will change the tropical mobile belt. This displacement due to rising temperatures will cause food and water shortages for millions of people.

The tropical mobile belt, known as the “Intertropical Convergence Zone” near the equator, is a wetland formed by the combination of winds from the northern and southern hemispheres. rain.

Based on 27 projection models, a team of researchers at the University of California published the study in the scientific journal Natural climate change By 2100, rainfall will change in East Africa, the Indian Ocean, and the South Atlantic and Pacific Oceans. “It is a process that affects the availability of water and food around the world,” said Antonios Mamalakis, one of the authors of the study. CBS News.

Drought increased

This displacement of rainfed areas will have serious repercussions for the people of these areas. Madagascar, for example, will face even more drought waves, while the country is hit by an unprecedented drought. By mid-January, the UN had called for $ 76 million in emergency aid to help the people of southern Madagascar. Drought. If the rain belt changes, millions of people around the world are likely to experience drought.

This effect may be accelerated in some areas depending on the emissions Greenhouse gas Climate change: “In Asia, aerosol emissions are forecast to decline, with the melting of the Himalayan glaciers and the loss of snow in the northern hemisphere due to global warming, said James Randerson. , To the American media, one of the co-authors of the study.

For these scientists, the next step will be to determine and quantify the effects of rain displacement on the level of the ecosystem and human infrastructure.
