What are the different forms of land degradation?
Types of land degradation assessed
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 three main types of land degradation?
These can be grouped into three major land degradation types, each of which can be subdivided according to a specific sub-set of degradation processes, namely: p Soil degradation; p Vegetation degradation; p Water resources degradation.
What are causes of land degradation PDF?
The most frequently recognised main causes of land degradation include: (i) overgrazing of rangeland; (ii) over-cultivation of cropland; (iii) waterlogging and salinization of irrigated land; (iv) deforestation; and (v) pollution and industrial causes.
What are the 4 main 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 the various causes of land degradation?
Land degradation has accelerated during the 20th and 21st centuries due to increasing and combined pressures of agricultural and livestock production (over-cultivation, overgrazing, forest conversion), urbanization, deforestation and extreme weather events such as droughts and coastal surges, which salinate land.
What are the different causes of land degradation Class 10?
Causes of land degradation
- Soil pollution.
- Soil Erosion.
- Overgrazing.
- Extraction of minerals at a repeated stage.
- Drought.
What is the most common cause of land degradation?
Land degradation is caused by multiple forces, including extreme weather conditions, particularly drought. It is also caused by human activities that pollute or degrade the quality of soils and land utility.
What are the 5 effects of land degradation?
These are: food production; fibre provision; microclimate regulation; water retention; and carbon storage. Its impacts can be far-reaching, including loss of soil fertility, destruction of species habitat and biodiversity, soil erosion, and excessive nutrient runoff into lakes.
What are the causes of land degradation How can we control?
The land degradations can be controlled by management of deforestation, manag-ing irrigation, managing urban sprawl, managing min-ing and quarrying, managing agricultural intensifica-tion and land reclamation.
What are the causes of land degradation give examples?
| Type of degradation | Percentage area of degradation type caused by | |
|---|---|---|
| Deforestation | Overcutting of vegetation | |
| Water erosion | 61 | 44 |
| Wind erosion | 21 | 98 |
| Soil fertility decline | 25 | 0 |
What are the main causes of land degradation by Brainly?
Answer
- Large scale soil erosion caused by running water and wind.
- Dumping of waste materials from mining centers and industrial units.
- Over irrigation leads to increase in salinity and alkalinity in the soil.
- Over grazing by animals and deforestation by man.
- Waste water from the industrial units pollute the lands.
What are the causes of degradation?
| Type of degradation | Percentage area of degradation type caused by | |
|---|---|---|
| Deforestation | Overgrazing | |
| Water erosion | 61 | 67 |
| Wind erosion | 21 | 46 |
| Soil fertility decline | 25 | 0 |
What is impacts of land degradation?
Its impacts can be far-reaching, including loss of soil fertility, destruction of species habitat and biodiversity, soil erosion, and excessive nutrient runoff into lakes. Read more: The immense challenge of desertification in sub-Saharan Africa.
What are the human factors in 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 is solution of land degradation?
The first and the most important step is to reduce all activities that cause land degradation in the first place. This includes deforestation, overgrazing, improper agricultural activities, mining, etc. Simply reducing the extent of these activities will prevent further land degradation.
What are effects of land degradation?
Its impacts can be far-reaching, including loss of soil fertility, destruction of species habitat and biodiversity, soil erosion, and excessive nutrient runoff into lakes. Land degradation also has serious knock-on effects for humans, such as malnutrition, disease, forced migration, cultural damage, and even war.
What are the factors of degradation?
High population pressure on land, deforestation, continuous expansion of agriculture land, fallow land are major anthropogenic factor of degradation in developing world whereas industrialization, urban expansion, heavy metal pollution are major land degradation factor in the developed world.
What is the biggest cause of land degradation?
What are the effects of land degradation?
How can we prevent land degradation?
5 possible solutions to soil degradation
- Curb industrial farming. Tilling, multiple harvests and agrochemicals have boosted yields at the expense of sustainability.
- Bring back the trees. Without plant and tree cover, erosion happens much more easily.
- Stop or limit ploughing.
- Replace goodness.
- Leave land alone.
How we can control land degradation?
Afforestation.

- Stop or limit ploughing.
- Replace goodness.
- Leave land alone.
What are the natural activities for land degradation?
Causes include:
- Land clearance, such as clearcutting and deforestation.
- Agricultural depletion of soil nutrients through poor farming practices.
- Livestock including overgrazing and overdrafting.
- Inappropriate irrigation and overdrafting.
- Urban sprawl and commercial development.
- Vehicle off-roading.

What Can We Do to Control Environmental Degradation?
- By planting more trees.
- Rainwater harvesting.
- Reduce, Reuse, and Recycle.
- By reducing the use of chlorofluorocarbons.
- Reduce fuel consumption.
- Treating the industrial effluents before dumping them in water bodies.
- Reducing the use of fertilizers.
- Control population growth.
