⚠️ What is Land Degradation?
🌱 Definition
Land degradation is the decline in the quality and productivity of land due to natural or human activities.
🌍 Causes of Land Degradation
🌿 1. Deforestation
- Removal of trees
- Leads to soil erosion
🌱 2. Overgrazing
- Excessive grazing by livestock
🌾 3. Soil Erosion
- Loss of topsoil due to wind and water
🌳 4. Urbanization
- Conversion of fertile land into built-up areas
⛏️ 5. Mining
- Disturbs land surface
🌍 6. Industrial Activities
- Pollution and waste disposal
🌡️ 7. Climate Change
- Droughts and extreme weather
🔄 Types of Land Degradation
🌱 Physical Degradation
