What is desertification?

Desertification is a process in which semi -dry soil turns into a desert, unable to maintain the life of plants or animals. Although desertification can be caused by natural processes, such as climate change, it is generally agreed that human influences significantly accelerate the degree of desertification around the world. Since the pressure on Earth increases as a result of increased population and global warming, it is estimated that the desertification rate can begin to increase rapidly and already causes serious social and environmental problems in some African countries. In Africa, the rapidly expanding Sahara and serious desertification in the Sahel area in West Africa are cited by a number of humanitarian organizations as an interest. For people, reduced to usable soil through desertification, it has a serious impact, especially on the impoverishment of indigenous people who cannot easily adapt to new life systems.

Desertification often begins in a conditionCurves of drought, although it does not always occur in drought. The upper layer of resistant plants is removed from the ground, which means there are no roots that hold the soil down. The winds carry nutritional topsoil else, leave the sand behind and create a great dealing of sand and dead plant material that interferes with human civilization. Animals are not able to feed food in these conditions, which means that nomadic nations lose a large part of their herds and because the whole life is dead, alternative food sources are not available. The soil is also exposed to the risk of floods and erosion begins to clog near water sources.

Climate change is obviously a factor in desertification, but also harmful human practices, such as poorly practiced irrigation that concentrates salts in the soil and kills plants. In addition, the deforestation and removal of the soil of all available plant life contributes to the problem. Especially in fine transient zones, they pushed through the desert and fully arable land with dessertsThe fication can stand very quickly and be completely irreversible. As topsoil disappears along with plants, the desert cannot maintain even minimal water supplies and quickly becomes completely dry.

The

effort is carried out by many humanitarian organizations, including the UN to stop desertification and try to recover the usable land. These include education on land use and reclamation tactics, such as inserting straw mats and soil holders in an effort to prevent blowing away. The robust rooted life of plants will also be planted in an effort to retain the soil. They also include many campaigns to end the overshoots, as desertification poses serious risks for proper nutrition: food and nutritional consignments are provided in areas experiencing desertification, hope that food will give a delicate temporary area a chance to recover.
