Resources and Development
"There is enough for everybody's need, but not for anybody's greed." — Mahatma Gandhi
1. Chapter Overview
This chapter answers: What ARE resources? How are they CLASSIFIED? Why do we need RESOURCE PLANNING? It examines India's LAND USE patterns, covers ALL MAJOR SOIL TYPES, and makes the case for SUSTAINABLE DEVELOPMENT — meeting present needs without compromising the future.
2. What is a Resource?
Definition
- Anything in our environment that can be used to satisfy human NEEDS
- BUT: it must be TECHNOLOGICALLY ACCESSIBLE, ECONOMICALLY FEASIBLE, and CULTURALLY ACCEPTABLE
The Key Insight
- Resources are NOT 'given' — they are MADE
- A thing becomes a RESOURCE only when humans have the TECHNOLOGY and DESIRE to use it
- Example: wind was always there; it became a resource when we invented WIND TURBINES
3. Classification of Resources
A. On the Basis of ORIGIN
| Type | Definition | Examples |
|---|---|---|
| Biotic | From the biosphere — have life | Plants, animals, fish, forests |
| Abiotic | Non-living things | Rocks, metals, water, air |
B. On the Basis of EXHAUSTIBILITY
| Type | Definition | Examples |
|---|---|---|
| Renewable | Can be replenished naturally | Solar, wind, water, forests, wildlife |
| Non-Renewable | Finite — once used, gone | Coal, petroleum, minerals |
C. On the Basis of OWNERSHIP
| Type | Definition | Examples |
|---|---|---|
| Individual | Owned by private persons | Farmland, houses, personal property |
| Community | Accessible to all members of a community | Village grazing ground, public parks |
| National | Belong to the NATION — government control | Roads, railways, minerals within territory |
| International | Beyond national boundaries — regulated by international bodies | Oceans beyond 200 nautical miles |
D. On the Basis of STATUS OF DEVELOPMENT
| Type | Definition | Examples |
|---|---|---|
| Potential | Exist in a region but NOT yet utilised | Rajasthan's solar/wind energy (partially untapped) |
| Developed | Surveyed, quality and quantity determined, being USED | Coal from Jharkhand, hydel power from Bhakra |
| Stock | Exist but we lack TECHNOLOGY to use them | Hydrogen as fuel (technology to use it is limited) |
| Reserve | Part of stock that can be used with EXISTING technology — but reserved for FUTURE | River water stored in dams, forests reserved for future |
4. Resource Planning
Why Needed?
- Resources are UNEVENLY distributed
- Some regions are RICH (Jharkhand — minerals) but economically POOR
- Some regions are economically RICH (Punjab — agriculture) but resource-POOR
- WASTAGE: resources used indiscriminately → depletion, pollution
Resource Planning in India — 3 Stages
- Identification and inventory: survey, map, measure resources (quantity, quality)
- Planning with appropriate technology: match technology to local resource conditions
- Matching with national development plans: coordinate local resource use with larger goals
Gandhiji's View
- Against MASS PRODUCTION overuse; for PRODUCTION BY MASSES
- Against CONSUMERISM; for NEEDS-BASED living
- 'There is enough for everybody's need, but not for anybody's greed'
5. Land Resources
Land Use in India
| Category | % of Total Area |
|---|---|
| Net sown area | ~44% |
| Forests | ~23% |
| Fallow land | ~8% |
| Non-agricultural (buildings, roads, etc.) | ~8% |
| Permanent pastures | ~4% |
| Culturable waste | ~4% |
| Other (barren, unculturable) | ~9% |
Land Degradation — Causes
- DEFORESTATION — cutting forests for agriculture, settlements
- OVERGRAZING — especially in Gujarat, Rajasthan
- MINING — especially in Jharkhand, Chhattisgarh, Odisha
- OVER-IRRIGATION — waterlogging, salinity (Punjab, Haryana)
- INDUSTRIAL WASTE — toxic chemicals pollute soil
- MINERAL PROCESSING — dust from grinding limestone, etc.
Land Conservation — Measures
- AFFORESTATION (planting trees)
- Controlled grazing
- Shelter belts (rows of trees to block wind)
- Proper waste management
- Mining: fill pits after extraction
- Regulated use of fertilisers and pesticides
6. Soil as a Resource
Why Soil Matters
- SOIL is the MEDIUM for plant growth
- Supports ALL terrestrial life
- Takes MILLIONS OF YEARS to form a few centimetres
- RENEWABLE but VERY slowly — must be conserved
SOIL EROSION
- Removal of fertile topsoil by WIND and WATER
- Causes: deforestation, overgrazing, improper farming, floods
- Sheet erosion: thin layer washed away by rainwater
- Gully erosion: deep channels cut into land (Chambal Valley — 'BAD LAND')
7. Major Soil Types in India
1. ALLUVIAL SOIL
- Formed by: Himalayan river systems (Indus, Ganga, Brahmaputra)
- Where: Northern Plains, river valleys, deltas
- Characteristics: VERY fertile, rich in potash, poor in nitrogen and phosphorus
- Two types: Khadar (newer, finer, more fertile — replenished by floods) and Bhangar (older, higher, has kankar nodules)
- Crops grown: Rice, wheat, sugarcane, pulses, oilseeds
2. BLACK SOIL (Regur)
- Formed by: Weathering of VOLCANIC (basalt) rocks
- Where: Deccan plateau — Maharashtra, Gujarat, Madhya Pradesh, Karnataka
- Characteristics: HIGH moisture retention (good for DRY farming); cracks in summer → aerates soil; rich in calcium carbonate, magnesium, potash; poor in phosphorus
- Crops grown: COTTON (ideal), sugarcane, wheat, jowar
- Nickname: 'Black cotton soil'
3. RED AND YELLOW SOIL
- Formed by: Weathering of IGNEOUS and METAMORPHIC rocks
- Where: Eastern and southern Deccan — Odisha, Chhattisgarh, southern Ganga plain
- Characteristics: Red colour from IRON; yellow when HYDRATED; sandy, not very fertile
- Crops grown: Millets, pulses, groundnut (with irrigation/fertiliser)
4. LATERITE SOIL
- Formed by: INTENSE LEACHING in HIGH RAINFALL, HIGH TEMPERATURE regions
- Where: Western Ghats, Eastern Ghats (summits), NE India, Kerala, Karnataka
- Characteristics: Low humus; acidic; LOW fertility
- Suitable for: Cashew, coffee, tea, rubber, spices — with fertilisers
- Also used for: BRICK making (hardens on exposure to air)
5. ARID / DESERT SOIL
- Where: Rajasthan, parts of Gujarat
- Characteristics: SANDY, low moisture, HIGH SALT (saline); kankar layer below
- Suitable for: Drought-resistant crops (bajra, pulses, guar) — WITH IRRIGATION
6. FOREST / MOUNTAIN SOIL
- Where: Himalayan region — valleys, slopes
- Characteristics: Varies with altitude; rich in humus on upper slopes; acidic; shallow on steep slopes
- Valley soils: fertile (alluvial deposits) — suitable for rice, wheat, maize
7. Check the map! Soil types — a common map-based question.
8. Soil Erosion and Conservation
Types of Soil Erosion
- Sheet erosion: Thin layer of topsoil washed away by WATER
- Gully erosion: Deep channels → 'bad land' (e.g., Chambal valley)
- Wind erosion: Topsoil blown away by strong winds (Rajasthan desert)
Conservation Methods
- Contour ploughing: Plough along contour lines — reduces water flow speed
- Terrace farming: Steps cut into slopes — Western and Central Himalayas
- Strip cropping: Alternate strips of grass between crops — breaks wind
- Shelter belts: Rows of trees to reduce wind erosion in dry areas
- Afforestation: Plant trees → roots hold soil
- Check dams: Small dams in gullies → reduce water flow, collect soil
- Mulching: Cover soil with organic material → retain moisture
9. Exam Focus
High-Weightage Topics
- Classification of resources (all four bases)
- Resource planning — 3 stages, why needed
- Land use pattern in India (percentages)
- All soil types — characteristics, distribution, crops
- Soil erosion — types, causes, conservation methods
- Sustainable development — concept and principles
10. Common Mistakes
-
All renewable resources are unlimited — NO. Even renewable resources (water, forests) can be DEPLETED if used faster than they regenerate. Freshwater is a classic example.
-
Khadar and Bhangar are different soil types — They are SUB-TYPES of ALLUVIAL soil. Khadar = newer, finer; Bhangar = older, coarser with kankar.
-
Red soil = laterite soil — NO. Red soil forms from crystalline rocks; laterite forms from INTENSE LEACHING in hot/wet climates. Different origin, different properties.
-
Black soil is only for cotton — It's IDEAL for cotton, but also grows sugarcane, wheat, jowar. It's the MOISTURE RETENTION that makes it special.
11. Conclusion
Resources and Development is the FOUNDATION chapter of Geography:
- RESOURCES: not 'given' — MADE by technology and need
- CLASSIFICATION: origin, exhaustibility, ownership, development status
- RESOURCE PLANNING: essential because resources are UNEVEN
- LAND: India's land use pattern; degradation and conservation
- SOILS: 6 major types — know their DISTRIBUTION, CHARACTERISTICS, and CROPS
For CBSE:
- The 4-way classification of resources is a common question
- SOIL MAP — know where each type is. Map question is frequent.
- Soil conservation methods — practical and exam-relevant
- Gandhi's quote = guaranteed 1 mark somewhere
The earth has enough — if we plan wisely and live simply.
