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

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 the term used to describe the process of fertile land turning into dry infertile desert?

The UN has defined desertification as a “diminution or destruction of the biological potential of the land which can lead ultimately to desert-like conditions.” Desertification can occur when extended periods of drought in arid, semi-arid, or dry sub-humid areas — known as drylands — sap the land’s productivity until …

What is the process of desertification?

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 cause of dry lands?

‘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.

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.

Are caused due to extra dryness of land?

Drylands are areas which face great water scarcity. They are highly adapted to climatic variability and water stress, but also extremely vulnerable to damaging human activities such as deforestation, overgrazing and unsustainable agricultural practices, which cause land degradation. …

What is the most effective way to protect dry lands from desertification?

Answer Expert Verified. Answer: Planting a tree belt. Explanation: The most effective method by which the desertification of the soil can be controlled is by planting more and more trees.

How are the fertile lands turning into wastelands?

On the ground, however, there is little to celebrate because the country’s fertile lands are turning into wastelands. According to a 2016 report by ISRO’s Space Applications Centre, desertification is underway across 96.4 million hectares, totalling around 30 per cent of the country’s land area.

Which is more fertile an oasis or a desert?

Although no more fertile that the surrounding desert, an oasis does have a permanent water source, such as a spring, that allows more plants to grow that in the surrounding arid land. What is a fertile place in the desert?

How does land degradation lead to water scarcity?

This happens because land degradation leads to the drying up of freshwater resources and increases the frequency of droughts. More alarmingly, the trends continue in a vicious cycle. With the degradation of natural water resources, soil quality degrades and leads to the loss of vegetational cover. And all of this, in turn, causes desertification.
