Study Notes
Natural Resources Overview
- Natural resources are valuable materials and energy derived from the Earth, essential for human life quality improvement and maintenance.
- These resources are categorized into renewable (naturally regenerating) and non-renewable (finite and slow to regenerate).
Renewable Resources
- Generated from natural processes via the interaction of Earth's physical and biological systems.
- Regeneration depends on maintaining balanced flows of matter and energy, unaffected by catastrophic changes or human activities.
Non-Renewable Resources
- Exist in limited quantities, including fossil fuels (coal, oil, natural gas), minerals, and ores.
- Their regeneration is extremely slow, rendering them nonrenewable on a human timescale.
Drivers of Resource Demand
- Growing global population increases resource consumption.
- Industrial growth expands demand across various sectors.
- Rising incomes and middle-class expansion drive consumption.
- Urbanization leads to concentrated resource demands.
Soil & Land Resources
- Soil is formed through weathering processes influenced by parent material, time, climate, biotic factors, and topography.
- Soil horizons develop through the vertical movement of materials like clay and nutrients.
Classification of Soils in India
- Indian Council of Agricultural Research divides Indian soils into eight major categories: Alluvial, Black, Red, Laterite, Forest, Arid/Desert, Saline/Alkaline, and Peaty/Marshy.
Land Degradation
- Fixed land availability with growing population pressures leads to conflicts in land use and agricultural efficiency.
- Importance of monitoring and studying land use to mitigate degradation.
Forest Resources
- Forests regulate CO2 levels and provide habitats for diverse species while also being vital for medicine and timber production.
- Major management challenges include depletion from natural events (fires) and human activities (deforestation).
Classification of Forests in India
- Very Dense Forests: Canopy density ≥70%
- Moderately Dense Forests: Canopy density 40%-70%
- Open Forests: Canopy density 10%-40%
- Scrub: Canopy density <10%
- Non-Forest: Areas outside these classifications.
Water Resources
- India receives about 4000 billion cubic meters of precipitation annually, with 80-95% during monsoon months.
- Uneven spatial distribution leads to regions with 300-3000 mm annual rainfall differences.
- Per capita water availability declined by nearly 20% over the last two decades.
Water Scarcity Challenges
- Social, political, economic, and environmental risks escalate due to increased urbanization and resource demand.
- Watershed management is crucial for conservation, soil erosion prevention, flood moderation, and groundwater recharge.
Mineral Resources
- Critical minerals are essential for economic growth and security; shortages can disrupt supply chains, emphasizing the need for sustainable management and extraction.
Energy Resources
- Non-Renewable: Include fossil fuels (petroleum, coal, gas).
- Renewable: Comprise wind, solar, hydro, tidal, and biofuels.
- Sustainable: Include nuclear power.
- Historical energy usage and consumption patterns indicate shifts towards diverse energy sources in India.
Energy Consumption Insights
- Significant variations in energy use across sectors highlight the importance of efficient energy consumption to support development goals.
