๐ Geography โ Chapter 2
Land, Soil, Water, Natural Vegetation and Wildlife Resources
๐๏ธ 1. Introduction
The Earth provides us with essential resources like land, soil, water, forests, and wildlife.
These resources are limited and need to be used wisely to ensure balance in nature.
Human activities such as farming, industries, and urbanisation put pressure on these resources.
๐ 2. Land Resources
๐ Importance of Land
- Land is the base for agriculture, industries, forests, houses, and roads.
- Only 30% of the Earth’s surface is land; the rest is water.
- Not all land is habitable โ mountains, deserts, and ice-covered regions are less suitable.
๐ Distribution of Land
- Mountains: 30% (forests, mining, tourism).
- Plains: 27% (agriculture, industries, settlements).
- Plateaus: 43% (minerals, forests, grazing land).
๐ก 3. Land Use Patterns
โ Land is used for:
- Agriculture ๐พ
- Forestry ๐ณ
- Pastures ๐
- Housing ๐
- Industries ๐ญ
- Mining โ๏ธ
โ ๏ธ Problems of Land Use:
- Deforestation ๐ฒโ
- Overgrazing ๐
- Urbanisation ๐๏ธ
- Landslides โฐ๏ธ
- Soil erosion ๐ช๏ธ
๐ฑ 4. Soil Resources
๐ What is Soil?
Soil is the topmost layer of the Earth where plants grow. It is formed by the weathering of rocks.
๐งช Factors of Soil Formation:
- Parent rock
- Climate
- Relief (slope, altitude)
- Flora, fauna, and microorganisms
- Time โณ
๐ Types of Soil in India:
- Alluvial Soil โ very fertile, good for crops ๐พ
- Black Soil โ rich in clay, ideal for cotton ๐ฟ
- Red Soil โ less fertile, needs fertilisers
- Laterite Soil โ found in high rainfall areas, good for tea & coffee โ
- Desert Soil โ sandy, less moisture ๐ต
โ ๏ธ Soil Degradation
- Overuse of chemical fertilisers
- Deforestation
- Overgrazing
- Mining activities
โ Soil Conservation Methods
- Terrace farming โฐ๏ธ
- Shelter belts ๐ฒ
- Contour ploughing
- Crop rotation ๐พ
๐ง 5. Water Resources
๐ Importance of Water
- Essential for drinking ๐ฐ
- Irrigation for crops ๐พ
- Power generation โก
- Industries ๐ญ
- Domestic use ๐ก
๐ Distribution of Water
- 97% โ Oceans (salty) ๐
- 2% โ Ice caps โ๏ธ
- 1% โ Fresh water (rivers, lakes, groundwater) ๐ง
โ ๏ธ Problems of Water
- Unequal distribution
- Overuse of groundwater
- Pollution of rivers and lakes
- Water scarcity in many regions
โ Conservation of Water
- Rainwater harvesting โ๏ธ
- Drip irrigation ๐ง๐ฑ
- Recycling wastewater
- Watershed management
๐ณ 6. Natural Vegetation
๐ Meaning
Natural vegetation refers to plants and trees that grow naturally without human interference.
๐ Types of Vegetation in India:
- Tropical Evergreen Forests โ Western Ghats, NE India ๐ด
- Tropical Deciduous Forests โ Central India ๐ณ
- Thorny Bushes โ Rajasthan, Gujarat ๐ต
- Mountain Vegetation โ Himalayas ๐ฒ
- Mangrove Forests โ Sundarbans ๐๐ฟ
โ Importance
- Provide oxygen
- Source of timber, medicine, fruits
- Control climate and rainfall
- Prevent soil erosion
๐ 7. Wildlife Resources
๐ Importance
- Balance in ecosystem ๐ฆ
- Provide food, medicine, and raw materials
- Attract tourism ๐๏ธ
โ ๏ธ Threats
- Hunting & poaching ๐ฆ
- Deforestation ๐ฒโ
- Pollution
- Climate change ๐ก๏ธ
โ Conservation
- National Parks ๐๏ธ
- Wildlife Sanctuaries ๐
- Biosphere Reserves
- Laws against poaching

๐ก Land Use Pattern in India
Land Use Type | Percentage |
---|---|
Agriculture | 51% |
Forests | 22% |
Grazing Land | 4% |
Wasteland | 6% |
Others (housing etc) | 17% |
๐ณ Forest Types in India
Forest Type | Location | Uses |
---|---|---|
Evergreen Forests ๐ด | Western Ghats, NE | Timber, rainfall |
Deciduous Forests ๐ณ | MP, UP, Odisha | Furniture, fuel |
Thorny Forests ๐ต | Rajasthan, Gujarat | Fodder, fuel |
Mountain Forests ๐ฒ | Himalayas | Herbs, tourism |
Mangroves ๐๐ฟ | Sundarbans, Andamans | Protect coasts |
๐ 9. Sustainable Development
We must use natural resources judiciously so that they are available for future generations.
Ways:
- Reduce, Reuse, Recycle โป๏ธ
- Afforestation ๐ฑ
- Water and soil conservation ๐ง
- Wildlife protection ๐ฏ
๐ 10. Summary
- Land, soil, water, vegetation, and wildlife are essential resources.
- Human activities are causing overuse and depletion.
- Conservation methods must be applied to ensure sustainable development.
