African agriculture is at risk of wiping out

Climate change will seriously threaten African agriculture today and will therefore adversely affect the rest of the world.

Research by scientists at the University of Leeds (UK) has just been published in the journal Nature Climate Change (USA) said, due to the effects of climate change, some agricultural areas in the sub-region Africa 's Sahara will be wiped out if it does not quickly transform the plant structure.

After examining the possible impacts of different climate change scenarios on Africa's most important crop varieties in each region, the team found, although 6 out of 9 species of plants The studied plants are likely to remain stable according to climate change scenarios, so other species may not be so lucky.

In particular, up to 30% of regions growing corn and bananas and 60% of coffee growing areas will no longer exist at the end of this century; Some areas will need to be converted effectively before 2025 to be able to harvest in the future.

Changes that help these agricultural areas exist include changing crops in certain areas, improving irrigation systems and in certain situations, even having to stop altogether. agricultural activities to allow the land to "rest" and recover.

Andy Challinor, a co-author of the study, said."We predict, in the next decade, many areas of maize and banana cultivation in sub-Saharan Africa will no longer be suitable for planting these crops."

"The amount of bananas from sub-Saharan Africa imported into the United Kingdom has doubled since 2001, suggesting that this issue means beyond the borders of Africa. These plants will be changed to responding to climate change and planning for these changes is very urgent Some solutions, including improvement of plant varieties, may take at least 15 years to complete, " he said. identify.
