The United Nations warns about the ongoing desertification phenomenon in the world

The United Nations says more than 250 million people worldwide are directly affected by the ongoing desertification. The United Nations is urging the organization of an early warning system to combat desert expansion.

At a recent meeting, senior officials from 179 member states participating in the United Nations Anti-desertification Convention (UNCCD) supported the call to conduct a new study on change. climate change, the cause of desertification.

Michel Jarraud general secretary of the conference proposed the development of a data bank to ensure systematic monitoring of soil degradation in the impacted areas, better understanding and anticipating progress. and the effects of drought and desertification.

Michel Jarraud spoke at the 7th session of the UNCCD member states held in Nairobi, Kenya. ' Research on the causes and effects of climate change and predictability over a long period of time is essential, with a view to provide early warning systems '.

According to the United Nations, there are currently 6.3 billion people in the world relying on only 11% of the vast land area of ​​the earth unaffected by desertification.

Experts are concerned that a normal food shortage may get worse when the desert encroaches on the remaining land. Especially according to the forecast of the earth population experts will reach 8.2 billion people by 2020.

Jarraud also said that the fight against land degradation is an urgent issue that is a top priority in an effort to try globally to ensure food security and livelihoods for millions of people. reside in arid lands in the world.

Africa, home to some 800 million people, is a highly impacted area, with 43% of the desert being the continent's harshest.

Since the conference, which has been held since 1996, only 91 of the more than 179 member countries attended the conference, fully presenting the national work plan to combat desertification.

Scientists say the heat of the greenhouse effect warns climate change.

Carbon dioxide is produced by burning coal, oil and gas, mainly emitted from stations and vehicles. These emissions and other emissions are called emitted gases of the greenhouse effect. They gather in the atmosphere, increasing the average temperature and global sea level.

The heat threatens to melt ice blocks in the Arctic, increasing the number and intensity of droughts, floods and storms worldwide.
