Study Notes
Natural Resources Overview
- Natural resources are materials and energy derived from the Earth that enhance human life quality.
- Essential elements include clean water, fertile soil, and clean air.
- Categorized as renewable or nonrenewable resources.
Renewable Resources
- Regenerate naturally through Earth's physical and biological interactions.
- Require a balanced flow of matter and energy to sustain regeneration without human interference or natural disasters.
Non-Renewable Resources
- Exist in finite quantities and cannot be replenished within a human lifetime.
- Includes fossil fuels, minerals, and ores.
- Regeneration is extremely slow relative to human timescales.
Drivers of Resource Demand
- Growing population pressures resource consumption.
- Expanding production in industrial and service sectors increases demand.
- Rising average income contributes to greater resource use.
- An enlarging middle class fuels consumption growth.
- Increased urbanization demands more resources.
Soil and Land Resources
- Soil formation is a complex process influenced by factors such as:
- Parent material
- Time
- Climate
- Plant and animal activity
- Land slope
- Soil horizons represent different layers within the soil, formed by downward movement of clay, water, and ions.
Classification of Soils in India
- Indian soils categorized into eight groups by the Indian Council of Agricultural Research:
- Alluvial Soils
- Black Soils
- Red Soils
- Laterite Soils
- Forest and Mountain Soils
- Arid and Desert Soils
- Saline and Alkaline Soils
- Peaty and Marshy Soils
Land Degradation
- Land is a crucial natural resource for agriculture; however, population growth strains this fixed resource.
- Sustainable land use requires study of its limitations and ongoing degradation challenges.
Forest Resources
- Forests are vital for maintaining Earth's CO2 balance, significantly impacting climate regulation.
