How many types of land degradation are there?
For the purpose of this study, the many and varied processes of land degradation have been grouped into six classes : water erosion, wind erosion, soil fertility decline, salinization, waterlogging, and lowering of the water table.
What are the four types of land degradation?
The major types of land degradation are soil ero- sion, soil salinity, soil acidity and soil contamination . Also mentioned when discussing these are nutrient loss and soil structure decline.

What is the process of degradation?
Degradation is the process by which a chemical substance is broken down to smaller molecules by biotic means (biodegradability) or abiotic means (hydrolysis, photolysis or oxidisation). Half-lives (DT50) are used as measures of the stability and persistence of a chemical substance in the environment.
What is land degradation in simple words?
Land degradation is the reduction or loss of the biological or economic productivity and complexity of rain —fed cropland, irrigated cropland, or range, pasture, forest or woodlands resulting from natural processes, land uses or other human activities and habitation patterns such as land contamination, soil erosion and ...
What is the most common form of land degradation?
The cost of land degradation
Water erosion is the most common form of degradation in the area, affecting 25 percent of agricultural land. Wind erosion affects 40 percent of the agricultural land in the dry zone.
What is the problem of land degradation?
Land degradation—the deterioration or loss of the productive capacity of the soils for present and future—is a global challenge that affects everyone through food insecurity, higher food prices, climate change, environmental hazards, and the loss of biodiversity and ecosystem services .
What are the major causes of land degradation?
The major causes of land degradation include, land clearance poor farming practices , overgrazing, inappropriate irrigation, urban sprawl, and commercial development, land pollution including industrial waste and quarrying of stone, sand and minerals.
What are 3 causes of soil degradation?
Soil degradation causes include agricultural, industrial, and commercial pollution ; loss of arable land due to urban expansion, overgrazing, and unsustainable agricultural practices; and long-term climatic changes.
What are the major types of soil degradation?
2.2 Types of soil degradation
The type of soil degradation refers to the nature of the degradation process ( displacement of soil material by water and wind ; in-situ deterioration by physical, chemical and biological processes).
Which two factors are responsible for land degradation?
Solution: Deforestation and the indiscriminate use of chemical pesticides and fertilisers in agricultural lands are two factors contributing to land degradation.
What are the causes and measures of land degradation?
