Class 10 Geography: Chapter 2 - Land, Soil, Water, Natural Vegetation and Wildlife Resources
Introduction
- The chapter will study various natural resources:
- Land Resources
- Water Resources
- Natural Vegetation and Wildlife Resources
- Land, soil, water, natural vegetation, and wildlife play a significant role in our lifestyle.
Land Resources
- Definition: All types of ground are termed land resources, whether fertile or not.
- Importance:
- 30% of the Earth's surface is land.
- A large part of all land areas is uninhabited, such as the Sahara Desert, dense forests of the Amazon, etc.
Land Use
- Uses: Agriculture, forestry, mining, construction, roads, and industries.
- Challenges:
- Meeting unlimited demands on limited land.
- Land use is determined by natural and human factors.
Determinants of Land Use
- Physical Factors: Topography, soil, climate, minerals.
- Human Factors: Population, technology.
Land Conservation
- Conservation Methods:
- Afforestation
- Land reclamation
- Controlled use of pesticides and fertilizers
- Prevention of overgrazing
Land Degradation
- Causes:
- Deforestation
- Overgrazing
- Soil erosion
- Problems: Land erosion, waterlogging, desertification.
Water Resources
- Importance: 3/4 of the Earth is water, but only 2.7% is fresh drinking water.
- Uses: Drinking, washing, agriculture, industry, power generation.
Water Conservation
- Regeneration: Through the water cycle.
- Conservation Measures:
- Wastewater treatment
- Rainwater harvesting
- Proper canal linkage
- Use of sprinklers and drip systems
Water Challenges
- Increasing demand for water due to growing population and urbanization.
- Pollution and overuse of water sources.
Natural Vegetation and Wildlife
- Definition:
- Natural Vegetation: Naturally growing trees and plants.
- Wildlife: Wild animals and birds.
Importance
- Oxygen production, herbs, wood, food, ecosystem balance.
- Wildlife: Meat, milk, skin, wool.
Conservation Measures
- National Parks, Wildlife Sanctuaries, Biosphere Reserves.
- Awareness programs, legal protection.
Conclusion
This chapter helps in understanding the importance of natural resources and the need for their conservation.
