Desertification

What Ca accustoms Desertification? -Overgrazing Overgrazing was non as large of a problem long ago because animals would croak in response to rainfall. People would stir up with the animals so it prevented overgrazing in such atomic number 18as. at once, populace have a steady solid faintt supply so they do non have to move about. Therefore, good deal use fences to keep their animals in one set up which causes overgrazing. (Desertification, 2001) -Farming of Average Land Farming of second-rate world is do desertification worldwide. Farmers are unclutter average land, and using it which takes for ward the fullness in the smirch.People should let the average land replenish itself before farming. (Desertification, 2005) -Destruction of Plants in ironic Regions Destruction of plants in dry localitys is causing desertification to occur. People are cutting batch tress to use them as a source of fuel. Once all these trees are cut down there is nought to protect the s mut. Therefore, it turns to dust and is pursy away by the wind. (Desertification, 2005) -Incorrect Irrigation in Arid Regions Causes a Build Up of Salt in the Soil Incorrect irrigation is commonly apply in suffering peopleer areas.Farmers are using transmission channel irrigation and other poor techniques because of the lack of water. This suit of irrigation causes a build up of saltiness in the realm. (Desertification, 2005)The Effects Of Desertification -Soil becomes less practicable The soil raft be blown away by wind or washed away rain. Nutrients in the soil can be removed by wind or water. Salt can build up in the soil which makes it harder for plant growth. -Vegetation is Lacked or Damaged unsnarled soil may bury plants or leave their grow exposed.Also, when overgrazing occurs, plant species may be lost. -Causes Famine Places that have war and poverty are most probable to have famine occur. Drought and poor land management contribute to famine. -Food divergence The soil is not suited for suppuration food therefore the amount of food being made will decline. If the commonwealth is growing, this will cause economic problems and starvation. -People border on Affected Areas Desertification can cause flooding, poor water tone, dust storms, and pollution. All of these make can hurt people spirit near an affected region. The Facts of Desertification and United Nations conventionalism to Combat Desertification, 2000)Case Stude The Sahel Desert In the Sahel Desert, desertification is go a huge problem. Around the 1950s, people settled into the Sahel region, in areas where there was water. This resulted in overgrazing, which is one of the greatest causes of desertification. Eventually, the perennial shrubs were destroy because of grazing, and they were replaced by annuals. Then, the annuals were grazed out which go forth bare soil. A lot of the surface soil was washed away, and all that was left were rocks.Silt cancelled hard when it was hit by rain. Therefore, plants were not able to grow because there roots could not penetrate this hard layer. Now this region has turned to desert and it continues to expand. (Desertification, The Sahel, 2004) Records try out that rainfall in Sahel has decreased and sands have shifted about sixty miles sulphur into the area. Sahel is expanding due to lack of vegetation in the area. (Sahel, 2005) Another reason desertification is occurring in the Sahel region is because people are using the cut down and burning method to clear land.This degrades the quality of soil just like overgrazing. (Desertification-a menace to the Sahel, 2000) Short Term Effects of Desertification in the Sahel -Soil loses its nutrients which makes it not useful -Overgrazing destroys vegetation and without it wearing away occurs -Land becomes salty which makes it difficult to grow crops vast Term Effects of Desertification in the Sahel -People die of starvation -Cattle die of starvation -The soil becomes completely useless (Prospects and Problems, 2004)
