How can we solve the problem of land degradation?
1 Answer
- Afforestation.
- Proper management & grazing land.
- Planting of shelter belts in desert areas.
- Control of overgrazing.
- Stabilization of sand dunes by growing theory bushes.
- Proper management of waste lands.
- Control on mining activities.
What are the two main causes of soil pollution?
Soil pollution is mostly caused by mindless human activities such as:
- Industrial waste.
- Deforestation.
- Excessive use of fertilisers and pesticides.
- Garbage pollution.
- Climate change.
- Loss of soil fertility.
- Impact on human health.
- Reforestation.
How does soil erosion affect humans?
Erosion increases the amount of dust carried by wind, which not only acts as an abrasive and air pollutant but also carries about 20 human infectious disease organisms, including anthrax and tuberculosis.
What are the causes and prevention of soil pollution?
residents. This addition is mostly by human activities such as mining, modern practices in agriculture, deforestation, indiscriminate dumping of human generated trash and unregulated disposal of untreated wastes of. various industries. Causes of Soil Pollution.
What is the importance of erosion?
Erosion is the process of soil, rock and other particles displacing from a location by wind and/or water (like stormwater runoff). Erosion affects wildlife, public and private property, and contributes to pollution so erosion and sediment control is very important.
What are the effects of soil?
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
How soil erosion can be conserved?
stopping rivers flooding. building small dams in gullies to slow down water run-off. digging channels across farm slopes to divert water. protecting areas likely to be eroded.
What are the main sources of soil pollution?
Various Sources of Soil Pollution
- Agricultural sources. Agricultural practices such as the use of non-organic products in crop and livestock production lead to soil pollution.
- Industrial sources.
- Urban waste.
- Sewer sludge.
- Mining and Smelting sources.
- Nuclear sources.
- Deforestation.
- Biological agents.
What are the control measures of soil pollution?
Recycling and Reuse of wastes: To minimize soil pollution, the wastes such as paper, plastics, metals, glasses, organics, petroleum products and industrial effluents etc should be recycled and reused. Ex: Industrial wastes should be properly treated at source. Integrated waste treatment methods should be adopted.
What are the causes and effect of soil pollution?
The primary cause of soil pollution is a lack of awareness in general people. Thus, due to many different human activities such as overuse of pesticides the soil will lose its fertility. Moreover, the presence of excess chemicals will increase the alkalinity or acidity of soil thus degrading the soil quality.
What are the main causes of soil pollution?
Illegal dumping of the solid wastes, polluted water absorbed by the soil, use of chemical fertilizers and pesticides, dumping of minerals, oils, and radioactive wastes are the major causes of soil pollution (Cachada et al. 2018). Soil fertility is severely affected due to the above-mentioned factors.
