1. Land Resources

• Land is used for agriculture, housing, industry, forests, and roads.
• Not all land is equally productive: fertility, terrain, and climate affect use.
• Types of land use: Agricultural land, forest land, grazing land, barren land, land for industries and cities.
• Land degradation causes: Deforestation, overgrazing, industrial pollution, mining.
• Conservation: Contour plowing, afforestation, controlled grazing.

2. Soil Resources

• Soil supports plant growth.
• Soil types: Alluvial, black, red, laterite, desert, mountain.
• Soil erosion causes: Water, wind, deforestation, overcultivation.
• Soil conservation: Terrace farming, windbreaks, crop rotation, afforestation.

3. Water Resources

• Water is essential for drinking, irrigation, industry, and hydroelectricity.
• Sources: Rivers, lakes, ponds, wells, groundwater, rainwater.
• Water scarcity causes: Overuse, pollution, uneven rainfall.
• Water conservation: Rainwater harvesting, check dams, drip irrigation, watershed management.

4. Natural Vegetation

• Plants growing naturally without human intervention.
• Types:
  • Tropical Rainforests – Heavy rainfall, dense forests (e.g., Western Ghats).
  • Deciduous Forests – Shed leaves in dry season (e.g., Peninsular India).
  • Thorn & Scrub Forests – Dry areas, thorny plants (e.g., Rajasthan).
  • Montane Forests – Hilly regions, coniferous trees (e.g., Himalayas).
  • Mangroves – Coastal wetlands (e.g., Sundarbans).
• Uses: Timber, medicine, food, oxygen, fuel.
• Conservation: Afforestation, protecting forests, controlled logging.

5. Wildlife Resources

• Animals living naturally in forests, mountains, wetlands, and oceans.
• Importance: Ecological balance, food chain, tourism, medicines.
• Threats: Poaching, habitat destruction, pollution, climate change.
• Conservation: Wildlife sanctuaries, national parks, biodiversity reserves, anti-poaching laws.
