RESOURCES By Origin By Ownership By Development Biotic Abiotic Individual National Developed Potential By Exhaustibility: Renewable | Non-Renewable
Classification of Resources — four main categories
Major Soil Types and Where They Are Found Soil Type Main Region / Use Alluvial Soil Northern plains — wheat, rice Black Soil (Regur) Deccan plateau — cotton Red & Yellow Soil Eastern Deccan — groundnut Laterite Soil South India hills — tea, coffee Arid Soil Rajasthan desert — needs irrigation Forest Soil Hill & mountain regions
Soil types in India — location and main uses
Land Use in India (Approximate) Net Sown Area ~46% Forests ~23% Fallow ~9% Pasture ~4% Non-agri / waste ~18% Punjab & Haryana NSA over 80% of land Arunachal Pradesh NSA below 10% of land Forest cover ideal: 33% Actual: below 23%
Approximate land use pattern in India
Soil Erosion: Types and Solutions Types of Erosion Sheet Erosion — water washes top layer Gully Erosion — deep channels formed Wind Erosion — dry loose soil blown away Ravines — bad land in Chambal basin Conservation Methods Contour ploughing — across slope Terrace farming — steps on hillside Strip cropping — grass strips between crops Shelter belts — tree rows stop wind

Three steps of resource planning in India

✏️ Section 3 — Worked Examples

📖 Worked Example 1

Question: Explain why Jharkhand is rich in resources but still economically backward.

1 Identify the resource richness: Jharkhand has large coal, iron ore and mica deposits.
2 Identify the limitations: The state lacks roads, schools, hospitals and skilled workers.
3 Connect to the concept: Resources need technology and good institutions to be useful.
4 Add evidence: Colonisation history shows minerals were taken out without local benefit.
Answer: Jharkhand has huge mineral wealth, but poor infrastructure and lack of technology stop it from becoming prosperous. Resources alone do not create development. Technology, skills and planning are equally important.

📖 Worked Example 2

Question: Compare alluvial soil and black soil under these headings: colour, fertility and main crop.

1 Alluvial soil: light grey to brownish colour; highly fertile; main crops — wheat and rice.
2 Black soil: deep black colour; holds moisture well; main crop — cotton.
3 Alluvial soil is deposited by rivers; black soil comes from Deccan volcanic rock (basalt).
4 Both are found in flat fertile plains; both support dense populations.
Answer: Alluvial soil (northern plains) is brownish, very fertile and good for rice and wheat. Black soil (Deccan plateau) is dark, holds water and is ideal for cotton. Both are India's most productive soils.

📖 Worked Example 3

Question: A farmer ploughs his field up and down the slope. What problem will this cause and how can it be fixed?

1 Ploughing up-down creates straight channels on the slope.
2 Rainwater rushes down these channels and carries away topsoil (erosion).
3 Solution: Plough across the slope along contour lines (contour ploughing).
4 This slows water flow, reduces erosion and helps water soak into the soil.
Answer: Up-down ploughing causes serious soil erosion. Contour ploughing (across the slope) slows runoff and saves topsoil. It is the most common method to stop hillside erosion.

📖 Worked Example 4

Question: What is sustainable development and how is Agenda 21 connected to it?

1 Sustainable development means meeting today's needs without harming future people's options.
2 The Brundtland Commission (1987) introduced this idea in "Our Common Future".
3 The 1992 Rio Earth Summit brought 100+ world leaders together to address environmental crisis.
4 Agenda 21 is a global plan signed at Rio to fight poverty, disease and environmental damage.
Answer: Sustainable development balances present growth with future needs. Agenda 21 (1992) is the world action plan for achieving this balance. Every local government was asked to create its own local plan (Local Agenda 21).

📋 Section 4 — Cheat Sheet

TermMeaning
ResourceAnything in the environment that meets our needs
Biotic ResourceLiving things — forests, animals, fish
Abiotic ResourceNon-living things — rocks, minerals, water
Renewable ResourceCan be replenished naturally — solar, wind, water
Non-Renewable ResourceFinite in nature — coal, petroleum
StockResource available but technology not yet developed
ReservePart of stock that can be used with current technology
Sustainable DevelopmentDevelop now without harming future generations
Agenda 21Global plan signed in 1992 for sustainable living
Alluvial SoilRiver-deposited soil of northern plains; most fertile
Black Soil (Regur)Dark volcanic soil of Deccan; best for cotton
Laterite SoilLeached acidic soil of south India hills
Contour PloughingPloughing across slope to reduce soil erosion
Shelter BeltRows of trees planted to stop wind erosion
Net Sown AreaLand actually used for growing crops

D1: Jharkhand and Chhattisgarh are rich in minerals but remain economically backward due to poor infrastructure and technology.
D2: Biotic resources are living (example: forests, fish). Abiotic resources are non-living (example: iron ore, water).
D3: Deforestation for farming, industry and human settlement has reduced forest cover. Encroachment on forest land has also reduced the area significantly.
E1: Punjab and Haryana have over 80% NSA. Arunachal Pradesh and Mizoram have below 10%.
E2: Alluvial soil is best for rice. It holds moisture well and is rich in nutrients like potash, phosphorus and lime, which rice needs to grow.
E3: Planting trees around the village; using organic methods that enrich soil; setting up composting units to reduce waste.
