What are the causes of land degradation?
Taking the form of desertification, deforestation, overgrazing, salinization, or soil erosion, land degradation can be caused by biophysical factors, such as the natural topography of an area or its rainfall, wind, and temperature; and unsustainable land management practices, such as deforestation, soil nutrient mining ….
What is land degradation and its effects?
Land degradation is a concept in which the value of the biophysical environment is affected by one or more combination of human induced processes acting upon the land. … Land degradation can be viewed as any change or disturbance to the land perceived to be deleterious or undesirable (Eswaran, 2001).
How do farmers protect soil?
With buffer zones, farmers plant strips of vegetation between fields and bodies of water such as streams and lakes. These plants help keep soil in place, keeping soil out of the water source. Buffer zones also act as a filter for water that flows from the field to the waterway.
What are human factors of land degradation?
Human interventions which are causing land degradation are (1) deforestation, (2) overgrazing by livestock, (3) mismanagement of agricultural land, (4) overexploitation of the vegetative cover for domestic use, and (5) (bio)industrial activities.
What are the 4 types of erosion?
The four main types of river erosion are abrasion, attrition, hydraulic action and solution. Abrasion is the process of sediments wearing down the bedrock and the banks.

What is land degradation What are its causes and how it can be controlled?
Increasing growth of population and demand for more residential areas and commercial sectors is also one of the reasons for land degradation. … Soil erosion is one of the factors responsible for lad degradation. It can be prevented by formation of ridge and furrow during irrigation which lessens run off.
How do farmers prevent soil erosion?
Planting Vegetation as ground cover: Farmers plant trees and grass to cover and bind the soil. Plants prevent wind and water erosion by covering the soil and binding the soil with their roots. The best choice of plants to prevent soil erosion are herbs, wild flowers and small trees.
How can we prevent soil degradation and conserve soil quality?
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 are the causes and effects of land degradation?
Land degradation results from the combined effects of processes such as loss of biological diversity and vegetative cover, soil loss nutrient imbalance, decline in soil organic matter and decrease of infiltration and water retention capacity. Soil erosion means the removal of top fertile layer of the soil.
