What are the main causes of desertification in Africa quizlet?

What are the 3 main causes of desertification? 1) Over-cultivation. 2) Overgrazing….

  • Population growth.
  • Farmers using marginal land for arable farming.

Overgrazing: Overgrazing is one of the major factors of land degradation or desertification.

What are the causes and effects of desertification in Africa?

The region currently faces extensive desertification caused by numerous factors. These factors include very high birth rates and thus expansion of agriculture into unsuitable areas, uncontrolled tree cutting for a fuel, all connected with effects of climate change and bad government policies.

What are the causes of desertification and drought?

Although the cycles of drought and climatic disturbances can contribute to the development of desertification, it is mainly caused by overgrazing, land clearance, over-exploitation of cultivated and natural lands, and by generally using land in a way that is inappropriate to local conditions.

What are the physical causes of desertification?

What causes desertification?

  • Climate change – especially long dry periods, causing drought.
  • Too many animals within the area – leads to overgrazing .
  • Population growth – traditional, less intensive, methods of farming decline.

What are the main causes of desertification in the Sahel?

But since the late 1960s, the Sahel has endured an extensive and severe drought. Desertification occurs when land surfaces are transformed by human activities, including overgrazing, deforestation, surface land mining, and poor irrigation techniques, during a natural time of drought.

What are the causes of drought and desertification in South Africa?

Whereas over cultivation, inappropriate agricultural practices, overgrazing and deforestation have been previously identified as the major causes of land degradation and desertification, it is in fact a result of much deeper underlying forces of socio-economic nature, such as poverty and total dependency on natural …

How does desertification effect the people in Africa?

Desertification often causes rural lands to become unable to support the same sized populations that previously lived there. This results in mass migrations out of rural areas and into urban areas (urbanisation), particularly in Africa. These migrations into the cities often cause large numbers of unemployed people, who end up living in slums.

Is desertification on the increase?

Sand dunes show the increasing desertification of the Tibetan Plateau, as land dries out and vegetation cover vanishes due to human activity. Humans are driving the transformation of drylands into desert on an unprecedented scale around the world, with serious consequences. But there are solutions.

Can drought cause desertification?

It is a misconception that droughts cause desertification. Droughts are common in arid and semiarid lands. Well-managed lands can recover from drought when the rains return. Continued land abuse during droughts, however, increases land degradation.

Is the Sahel region facing desertification?

The Sahel is facing a big problem, Desertification . As the climate of Sahel was mainly dry and hot and leads to a high evaporation rate and also little rainfalls. The distribution of rainfall in the Sahel region is uneven. The rainfall in the region has been below average since 1970. The Sahel is becoming drier on the whole.
