Land Degradation And Conservation Measures
1. Importance of Land for Human Needs:
- Land provides 95% of our basic needs for food, shelter, and clothing.
- We share land with both past and future generations, making its conservation crucial.
2. Causes of Land Degradation:
- Human Activities: Activities like deforestation, overgrazing, mining, and quarrying have accelerated land degradation.
- Deforestation and Mining: In states like Jharkhand, Chhattisgarh, Madhya Pradesh, and Odisha, mining-related deforestation is a significant cause of land degradation.
- Overgrazing: Overgrazing is a major issue in Gujarat, Rajasthan, Madhya Pradesh, and Maharashtra, leading to land degradation.
- Over-Irrigation: In Punjab, Haryana, and western Uttar Pradesh, over-irrigation causes waterlogging, increasing soil salinity and alkalinity.
- Industrial Pollution: Dust from mineral processing and industrial effluents contribute to land and water degradation by preventing water infiltration and polluting the environment.
3. Consequences of Mining:
- Abandoned mining sites leave deep scars and overburden traces, severely damaging the land.
4. Solutions to Land Degradation:
- Afforestation: Planting trees can help restore degraded lands.
- Proper Grazing Management: Controlling grazing practices can reduce land degradation.
- Stabilization in Arid Areas: Planting shelter belts, controlling overgrazing, and stabilizing sand dunes with thorny bushes are effective in arid regions.
- Waste Land Management: Proper management of waste lands can mitigate degradation.
- Mining Control: Regulating mining activities can reduce environmental impact.
- Industrial Waste Management: Proper treatment and disposal of industrial effluents can reduce pollution and land degradation in industrial and suburban areas.
