Study Notes
Resource Planning in India
- Resource planning involves identifying and inventorying resources across regions, evolving a planning structure with technology and institutional setup for resource development.
- It involves surveying, mapping, and estimating resources qualitatively and quantitatively.
Land Resources
- Land is a natural resource of utmost importance, supporting natural vegetation, wildlife, human life, economic activities, transport, and communication systems.
- India has land under various relief features: mountains (30% of the total surface area), plateaus (27% of the total area), and plains (43% of the total area).
Land Utilisation in India
- Land resources are used for:
- Forests
- Land not available for cultivation (barren and waste land, land put to non-agricultural uses)
- Other uncultivated land (permanent pastures and grazing land, land under miscellaneous tree crops)
- Fallow lands (current fallow and other than current fallow)
- Net sown area (physical extent of land on which crops are sown and harvested)
Soil Formation and Types
- Soil formation involves physical and chemical changes in the topsoil, subsoil, and weathered parent rock material.
- Soils in India are classified into different types based on factors like relief features, landforms, climatic realms, and vegetation types.
- Main types of soils in India:
- Alluvial Soils (most widely spread, found in northern plains, Rajasthan, and Gujarat)
- Black Soils (found in Deccan plateau, rich in soil nutrients, capable of holding moisture)
- Red and Yellow Soils (develop on crystalline igneous rocks, found in eastern and southern parts of Deccan plateau)
- Laterite Soil (develops under tropical and subtropical climate, found in areas with alternate wet and dry seasons)
