Relevant Facts
- Extent of Soil Degradation:
- “Around 29.7% of land is degraded in India” (ISRO Atlas, 2021).
- Nutrient Loss:
- “Approximately 3.7 million hectares suffer from nutrient loss in soil” (Source: ISRO Atlas).
- Impact of Heavy Metals:
- “Industrial activities like mining, manufacturing, and e-waste dumping lead to heavy metal contamination” (Source: Environmental Studies).
- Climate Change Effects:
- “Changing weather patterns cause excessive rainfall and floods that erode topsoil” (Source: Climate Reports).
- Agricultural Practices:
- “Overuse of agrochemicals causes soil acidification and reduces organic matter” (Source: Agricultural Research Journals).
- Deforestation Impact:
- “Deforestation reduces humus and litter layers, affecting soil health” (Source: Forestry Studies).
- Urbanization Issues:
- “Urban development results in soil compaction and increased runoff” (Source: Urban Ecology Research).
- Government Initiatives:
- “The Soil Health Card Scheme aims to improve soil health management” (Source: Government Reports).

Model Answer
Causes of Widespread Soil Degradation in India
Soil degradation in India is a pressing issue, with approximately 29.7% of land affected, as reported by the ISRO Atlas in 2021. The primary causes include:
Measures to Tackle Soil Pollution
In response to soil degradation, the Indian government has implemented several initiatives:
These measures are crucial for restoring soil health and achieving India’s goal of rehabilitating 26 million hectares of degraded land by 2030, which will also contribute to climate change mitigation by enhancing carbon sequestration in soils.
