What is desertification give two reasons for desertification?



Climatic variations’ and ‘Human activities’ can be regarded as the two main causes of desertification. removal of the natural vegetation cover(by taking too much fuel wood), agricultural activities in the vulnerable ecosystems of arid and semi-arid areas, which are thus strained beyond their capacity.

What is desertification explain?

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.

What are 3 causes to 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 10 causes of desertification?

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

What are examples of desertification?

Additional savannas, grasslands, and woodlands are common indications of desertification in arid and semi-arid areas. Well-known examples of this occurrence include, Europe’s Adriatic Sea, the Middle-East’s Saharan desert, and China’s Taklamakhan Desert. Sand dunes are formed in the Sahara Desert in the image above.

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 is desertification in Brainly?





Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife.[ 2] It is caused by a variety of factors, such as climate change and human activities.

What are the causes and effects of 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 is desertification for kids?

Desert environments are expanding in many areas of the world. The spread or encroachment of a desert environment into a nondesert region is a process known as desertification. This process results from a number of factors, including changes in climate and the influence of human activities.

What are the causes of deforestation?

Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization.

What is desertification Wikipedia?

Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid.



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 main cause of desertification in Africa?

Poverty-related agricultural practices are a major contributor to desertification. Continuous cultivation without adding supplements, overgrazing, lack of soil and water conservation structures, and indiscriminate bushfires aggravate the process of desertification.

What is deforestation PDF?

According to FAO (2020), deforestation is the conversion of a forest area into other land uses. Meanwhile, Hosonuma et al. (2012) defines deforestation as the abolishment of forest cover and the changing of forest vegetation into non-forest vegetation or other land uses, such as plantation, mining, etc.

What is land desertification?

Desertification is a form of land degradation by which fertile land becomes desert.

What are the features of desertification?

GENERAL CHARACTERISTICS: what is desertification? “Desertification is the degradation of drylands. It involves the loss of biological or economic productivity and complexity in croplands, pastures, and woodlands. It is due mainly to climate variability and unsustainable human activities.



What are the causes and effects of desertification?

Human activities, including deforestation and the overexploitation of aquifers, accelerate desertification. The effects of climate change, which is also driven by humans, and the destruction it causes in the form of extreme weather phenomena such as droughts, hurricanes, fires, etc.

Why is desertification a problem?

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.

What is desertification for kids?
