What are some examples of desertification?

Three Desertification Examples

  • Example Number 1: Sahel Region, Northern Africa. The Sahel region is a strip of land that stretches from one side of northern Africa to the other.
  • Example Number 2: Ningxia Hui, China.
  • Example Number 3: Murray-Darling Basin, Australia.

What is desertification and its causes?

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. Desertification is a process of degradation of the land.

Where does desertification mostly occur?

Africa is the continent most affected by desertification, and one of the most obvious natural borders on the landmass is the southern edge of the Sahara desert. The countries that lie on the edge of the Sahara are among the poorest in the world, and they are subject to periodic droughts that devastate their peoples.

What are the 5 major causes for desertification?

Overgrazing is the major cause of desertification worldwide. 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.

What are the 5 effects of desertification?

CONSEQUENCES OF DESERTIFICATION The loss of vegetation cover and therefore of food for livestock and humans. Increased risk of zoonotic diseases, such as COVID-19. Loss of forest cover, with a corresponding shortage of wood resources. The decrease in drinking water reserves due to the loss of aquifers.

What are 4 causes of desertification?

Various Causes of Desertification

  • Overgrazing.
  • Deforestation.
  • Farming Practices.
  • Excessive Use of Fertilizers and Pesticides.
  • Overdrafting of groundwater.
  • Urbanization and Other Types of Land Development.
  • Climate Change.
  • Stripping the Land of Resources.

What are the 6 effects of desertification?

What is desertification PDF?

factors, including climatic variations and human activities, is called desertification. (Anonymous, 1992). It is a slow process of land degradation that exacerbates the quality of. land, leading to decline in its productivity and thus impacting the livelihood of the people. depending on it.

What are effects of desertification?

Desertification affects topsoil, groundwater reserves, surface runoff, human, animal, and plant populations. Water scarcity in drylands limits the production of wood, crops, forage, and other services that ecosystems provide to our community.

How does climate affect desertification?

It is essential to recognise that desertification is essentially a man-made phenomenon which is exacerbated by climate change. This is because an increase in weather extremes such as droughts and heavy rains as a result of climate change will lead to further land degradation.

What are 7 consequences of desertification?

CONSEQUENCES OF DESERTIFICATION Loss of biodiversity by worsening the living conditions of many species. Food insecurity due to crop failure or reduced yields. The loss of vegetation cover and therefore of food for livestock and humans. Increased risk of zoonotic diseases, such as COVID-19.

What are 10 causes of desertification?

Causes and Effects of Desertification on People and the Environment

  • Overgrazing.
  • Unsustainable agriculture techniques.
  • Deforestation.
  • Unsustainable water management.
  • Overpopulation and overexploitation of natural resources.
  • Urbanization and development of tourism.
  • Famine, poverty and political instability.
  • Climate change.

What human activities cause desertification?

Human activities that contribute to desertification include the expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing. These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology.

What are the five main causes of desertification?

What is desertification PPT?

What is desertification • Desertification is land degradation process in arid and semi-arid areas. • It is a process by which fertile land is transformed into desert. • It becomes progressively drier • Unable to support any plant growth for food production.

What is the impact of desertification?

How can we prevent desertification?

Planting more trees – the roots of trees hold the soil together and help to reduce soil erosion from wind and rain. Improving the quality of the soil – this can be managed by encouraging people to reduce the number of grazing animals they have and grow crops instead.

What are the impact of desertification on the environment?

Desertification has caused major environmental and socioeconomic problems in many arid and semiarid areas of the world1. It causes soil degradation and severely reduces potential land productivity2–4, which causes degradation of the ecosystem and its associated ecosystem services.

What countries are affected by desertification?

These regions – representing around 14 million hectares – show high sensitivity to desertification. Thirteen Member States have declared themselves affected by desertification under UNCCD: Bulgaria, Croatia, Cyprus, Greece, Hungary, Italy, Latvia, Malta, Portugal, Romania, Slovakia, Slovenia and Spain.
