Desertification is the degradation process by which a fertile land changes itself into a desert by losing its flora and fauna, this can be caused by drought, deforestation, climate change, human activities or improper agriculture. Causes Of Desertification. Desertification 20 terms. 3. According to Mr. Luc Gnacadja, executive secretary of the United Nations Convention to Combat Desertification, "Land degradation is a global phenomenon, with 78 percent . These include indirect factors such as population pressure, socioeconomic and policy factors, and international trade as well as direct factors such as land use patterns and practices and climate-related processes. For instance, typhoons that hit in the area erode the soil causing it to reduce the soil quality. No doubt severe droughts do take place, and their effects become worse as human and domestic . 1. 3.2 Causes of Desertification 3) Overuse of fuel wood. This excessive agricultural pursuit leads to the nutrition in the land become exhausted and turn to an unrecoverable situation. Three main causes for desertification include the following: Climate change caused drought reduces plant population which retains nutrients in soil and prevents erosion. The main causes of desertification include: Population growth - the population in some desert areas is increasing. Land desertification, species extinction and climate transformation, these three problems all are a long term problem to the world. Overgrazing is the major cause of desertification worldwide. This can happen naturally due to a drought or can be caused by human activities. Desertification is a big global problem, which will become even worse due to the effects of global warming. Experts have asked whether it is the result of temporary serious droughts, long-term climatic change, or human actions degrading the biological environments in arid zones. Extended droughts may mimic desertification, but vegetation may recover when seasonal rains return. Chloe_Jones53. Desertification can be defined as land degradation implying the loss of biological productivity due to the development of land into an arid desert-like environment. The vulnerability to desertification of land is determined by current climate, relief, and the state of the soil and natural vegetation. 3. Overgrazing is the major cause of desertification worldwide. These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology. It occurs because of man-made activities and climate change. Desertification is the process of land turning into desert as the quality of the soil declines over time. 1) Over-cultivation. Desertification is a worldwide phenomenon: it affects about two-thirds of the countries of the world and one-third of the earth's land surface, on which approximately one billion people live. . Sometimes the two can combine and natural processes of desertification that are already underway can be accelerated and made worse by humans. Click to see full answer. Other factors that cause desertification include urbanization, climate change, overdrafting of groundwater, deforestation, natural disasters and tillage practices in agriculture that place soils more vulnerable to wind. The increase in temperature of the planet decreases humidity, increases drought, and produces desertification. - Related Questions One of the causes of desertification is the destruction of plants. It is the spread of arid areas caused by a variety of factors, such as climate change (particularly the current global warming) and overexploitation of soil as a result of human activity. It is caused by a mixture of climate change and the issues raised by population pressure. Permanent changes in climate, particularly rainfall, are responsible for natural desertification. Permanent changes in climate, particularly rainfall, are responsible for natural desertification. Causes Of Land Desertification. What is desertification caused by? Causes of soil degradation 16 terms. Earlier, the main crops cultivated here used to be cereal and oilseeds. Other factors that cause desertification include urbanization, climate change, overuse of groundwater, deforestation, natural disasters, and tillage practices in agriculture that make soils more vulnerable to wind. Famine, poverty and political instability 8. The causes of desertification remain controversial. The natural factors are largely associated with climate variability especially droughts, while some human activities in the drylands is the major cause, especially in Africa. Kieran_Sinden8. These include indirect factors such as population pressure, socioeconomic and policy factors, and international trade as well as direct factors such as land use patterns and practices and climate-related processes. Desertification as a social process which focuses on humans as the cause of decreasing agricultural productivity • 3. Over cultivation . Overgrazing 2. Desertification does not concern natural deserts, and can only occur on land which is vulnerable to the desertification process. 1. The decline in productivity of land occurs due to climate change, deforestation, poverty, unsustainable practices. where soils are depleted of their nutrients. Desertification In The Sahel Introduction You read in the chapter on Land Degradation that: Desertification is the degradation of land in arid, semi-arid, and dry sub-humid areas. Causes of Desertification: Deforestation: The most important cause is the loss of vegetation. The vast majority of desertification in the present day is caused by harmful human activity. IB Geography - Topic 3 - Patterns of Environmental Quality and Sustainability 31 terms. The soil becomes more and more loose and it does not have any nutrition and water. In areas of low precipitation, like Sub-Saharan Africa, long droughts that turn arid land to unproductive, barren soil are a frequent cause of desertification. In this lesson, we will explain how climate change, population growth and the removal of fuel wood can cause desertification. The causes of desertification.

In places where there are developments in mining and tourism, people are attracted by jobs. What are the 2 main consequences of desertification? The main causes of desertification include . Studies have shown that, in many environments, the rate of erosion and runoff decreases exponentially with increased vegetation cover. Humans are driving the transformation of drylands into desert on an unprecedented scale around the world, with serious consequences. This happens most often on the edges of an existing desert, such as the Sahara or the Thar. Drought is a very long period of dry weather, which affects soil moisture, leads to the death of vegetation, and the expanse of land. Avoiding Over-cultivation and Overgrazing: Farmers should avoid repetitive crop production. Over Cultivation. On other hand overgrazing, over cultivation and salinization in irrigated croplands are also affecting desertification rates. An increased population is putting greater pressure on the environment for resources such as wood and water. Unsustainable agriculture techniques 3. Other factors that cause desertification include urbanization, climate change, overuse of groundwater , deforestation, natural disasters, and tillage practices in agriculture that make soils more vulnerable to wind. Urbanization and development of tourism 7. Over drafting is the process of extracting excessive amounts of water by pumping them up from underground aquifers. Desertification is a process of land degradation that reduces its productivity, and its impact may be confined to relatively small scales (Dregne, et al . Climate Change. https://reliefweb.int/report/world/high-price-desertification-23-hectares-land . This happens mainly as a result of human activity and hot, dry climates that make it difficult for the land to recover. The causes of desertification are due to a multitude of factors, including climate change, human misuse of land and natural disasters which all contribute to the problem, but not one factor alone can be underlined. Desertification does not refer to the expansion of existing deserts. 2) Overgrazing. Overgrazing is the major cause of desertification worldwide. 4.3/5 (177 Views . These causes leads to destruction of vegetation that result in extinction of species, soil erosion and soil infertility, increase vulnerability of natural disasters, pollution of soil, air and water, rise .
