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.
