- Overdrafting of groundwater.
- Urbanization and Other Types of Land Development.
- Climate Change.
- Stripping the Land of Resources.
What is the most efficient way of controlling land degradation?
Suggested methods in reducing land degradation include the following: Gardening, Conservation Tillage, Using Fertilizers, Afforestation and Reforestation, Constructing Wind Breakers and Responsible Industrial and Chemical Waste Management.
What steps can be taken to prevent land degradation?
Prevention and Control Measures for Land Degradation:
- Strip farming: It is & practice in which cultivated crops are sown in alternative strips to prevent water movement.
- Crop Rotation:
- Ridge and Furrow Formation:
- Construction of Dams:
- Contour Farming:
What is desertification Byjus?
Desertification is a type of land degradation in which a relatively dry area of land becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife . Desertification is a significant global ecological and environmental problem.
What are major forces behind 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.
How is land degraded by industries explain any two methods to control land degradation caused by industries?
1. Proper discharge and disposal of industrial wastes and effluents can control land degradation. 2. Control on mining and quarrying activities is another method to control land degradation caused by Industries.
What are the causes of land degradation in India?
7 Main Causes of Land Degradation in India (With Remedies)
- Excessive Population Pressure on Land: India’s population of over 1000 million people is more than that of the whole world prior to the Industrial Revolution.
- Deforestation: ADVERTISEMENTS:
- Erosion:
- Over-Irrigation:
- Floods and Droughts:
- Grazing:
- Pollution:
What are six ways farmers can stop soil degradation?
Here are a few to note:
- Wind breaks. Artificial and natural windbreaks, such as shrubs, reduce the erosion effects of wind.
- Terracing. Terracing of slopes reduces the effects of water runoff and helps conserve rain water.
- Strip farming.
- Crop rotation.
What are the different measures taken for land conservation?
Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants die, they decay and become part of the soil. Code 330 defines standard methods recommended by the U.S. Natural Resources Conservation Service.
What is the percentage of desertification in India?
Desertification in India. Of India’s total geographical area of 328.72 million hectares (MHA), 96.4 MHA (32%) is under desertification. In eight states—Rajasthan, Delhi, Goa, Maharashtra, Jharkhand, Nagaland, Tripura and Himachal Pradesh—around 40 to 70 per cent of land has undergone desertification.

India became a signatory to UNCCD on October 14, 1994, and ratified it on December 17, 1996.
How can we prevent desertification?
To prevent desertification steps to be taken are: Land and water management: Sustainable land use can fix issues such as overgrazing, overexploitation of plants, trampling of soils and irrigation practices that cause and worsen desertification.
