What is the process of fertile land changing into a desert?

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. It is caused by a variety of factors, such as climate change and human activities.

What is the name of the process by which fertile land becomes dry and barren due to the spreading of desert area?

Desertification is defined as land degradation in arid, semiarid, and dry subhumid areas resulting from temporary climatic crises, especially droughts that occur periodically, and harmful human activities in vulnerable ecosystems.

What is a fertile land in the desert known as?

Answer: The fertile land in desert where water and vegetation is found is called an Oasis.

What prevents fertile land becoming a desert?

Preventive actions include:

Integrating land and water management to protect soils from erosion, salinization, and other forms of degradation.
Protecting the vegetative cover, which can be a major instrument for soil conservation against wind and water erosion.

What are 3 causes of 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.

Can the desert be made fertile?

The deserts are very fertile, which means that, if provided with water, they can grow a lot of food. This can by done by providing water with irrigation technology. Irrigating in a dry climate, especially flood irrigation can cause the water to evaporate very quickly.

How can we stop the spread of deserts?

Farmers can stop deserts from spreading by carefully managing their land. If you have hilly land, you should be ploughing the land along the curves of the land, and around the hills, instead of straight up and down. Leave strips of grass between the cultivated rows.

Is Sahara growing?

While the desert waxes and wanes with the drought that comes with the changing seasons, declining rainfall combined with deforestation and soil degradation has seen it grow. Over the past century, the Sahara desert has been expanding by more than 7,600sq km a year and is now 10% larger than it was in 1920.

Can we turn the Sahara green?

So, a future Green Sahara event is still highly likely in the distant future. Today’s rising greenhouse gases could even have their own greening effect on the Sahara, though not to the degree of the orbital-forced changes, according to a March review published in the journal One Earth.

Can we turn desert into forest?

While it is technically possible to turn a desert into a forest, it is a process that would probably take more than several decades. The process of turning deserts into forests is called desert greening, and it is something that has been going on for several years now.

What is the main reason of 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 are the main causes of drought?

A lack of water in stores such as rivers, lakes, reservoirs and aquifers (water stored underground naturally) can lead to drought. Areas that rely on rainfall and surface water are more likely to experience drought. Surface water quickly evaporates in warm, dry conditions leading to an increased risk of drought.
