The major causes of desertification of the earth

Control of desertification

But poor people are affected the most. In Ethiopia, FAO calculates that desertification causes the loss of 92, hectares of woodlands every year, along with 2 billion tons of fertile, productive soil. Overgrazing is the major cause of desertification worldwide. Not all deserts are dry; those that are wet could experience a lot of flooding because there is nothing to stop the water from gathering and going all over the place. If people are using land to get natural resources or they are developing it for people to live on, then the policies that govern them should be ones that will help the land to thrive instead of allowing them to harm the land further. Without food and water, it becomes harder for people to thrive, and they take a lot of time to try and get the things that they need. Many entering the U.

There is a suggestion that the last time that the Sahara was converted from savanna to desert it was partially due to overgrazing by the cattle of the local population. They may essentially strip the land of everything that it has before moving on to another plot of land.

Sustainable practices to prevent desertification from happening. The figure could reach up to 10 billion by the end of this century. Dry woodlands, which are plagued by the overconsumption of fuelwood.

physical causes of desertification

By stripping the soil of its nutrientsdesertification becomes more and more of a reality for the area that is being used for farming. Is it preventable? This, in turn, will help to soften the blow of overgrazing and generate clean energy, all while preventing soil erosion and desertification.

What is Desertification? Many scientists think that one of the most common causes is overgrazingtoo much consumption of vegetation by cattle.

Desertification solutions

Where Does Desertification Occur? Irrigated croplands Nearly 2,, square km about 1,, square miles of croplands are irrigated. Effects of Desertification Farming becomes next to impossible. All areas situated in the eastern part of Africa i. Mining and climate change are also major causes. As areas become more urbanized, there are less places for plants to grow, thus causing desertification. In India, during the 80s, in Banni grasslands, Rajasthan, there was a huge loss to livestock as well as grassland in the previous decade. As mentioned above, development can cause people to go through and kill the plant life. The loss of topsoil means that plants cannot take root firmly and can be uprooted by torrential water or strong winds. The conference explored the causes and contributing factors and also possible local and regional solutions to the phenomenon. Population growth and increased food demand are expected to drive the expansion and intensification of land cultivation in drylands. The process involves enabling native sprouting tree growth through selective pruning of shrub shoots. Certainly, some dryland areas have been irrigated for millennia, but other areas are more fragile. Grazing livestock, usually not left to wander, would eat the grass and would minimize any grass growth while grass left alone would eventually grow to cover its own growing buds, preventing them from photosynthesizing and killing the plant. This is because the plant life plays a significant role in keeping the water clean and clear; without its presence, it becomes a lot more difficult for you to be able to do that.

These migrations into the cities often cause large numbers of unemployed people, who end up living in slums. Additionally, properly spaced and pruned trees can increase crop yields.

what is desertification

Overpopulation: When areas start to become desert, animals and people will go to other areas where they can actually thrive.

This simple and low-cost method has enabled farmers to regenerate some 30, square kilometers in Niger. Desertification is defined as a process of land degradation in arid, semi-arid and sub-humid areas due to various factors including climatic variations and human activities.
