Resources and Development
Why This Chapter Matters
This is Geography Chapter 1 in Class 10 — 4-6 marks in boards every year. Resource classification, land use, soil types, and conservation methods are the key topics tested.
Core Concepts
1. What is a Resource?
Everything in the environment which can be used to satisfy human needs — provided it is:
Resources are not static — something becomes a resource when humans find a way to use it.
2. Classification of Resources
On the basis of origin:
Biotic: living things (plants, animals, fish)
Abiotic: non-living things (rocks, minerals, water, metals)
On the basis of exhaustibility:
Renewable: can be regenerated (solar energy, wind, water, forests)
Non-renewable: formed over millions of years, cannot be quickly renewed (coal, oil, minerals)
On the basis of ownership:
Individual: owned privately (land, house, pond)
Community/Common property: accessible to all community members (common pastures, village ponds)
National: owned by the state (forests, rivers, minerals, ocean within territorial limit)
International: beyond national jurisdiction (open oceans, celestial bodies, Antarctica)
On the basis of development:
Potential: found but not used (Rajasthan wind/solar — vast potential)
Developed/Stock: surveyed and being used
Reserves: currently not being used but can be used in future
3. Resource Planning in India
Resources are not evenly distributed. India has:
Resource planning involves:
4. Land Resources
Land degradation:
Conservation:
Land use categories:
Forest land | Barren/uncultivable | Permanent pastures | Miscellaneous tree crops | Cultivable waste | Fallow lands | Net sown area
India's net sown area is highest in Punjab and Haryana. Net sown area has increased since independence but forest area has remained largely unchanged.
5. Soil Resources
Soil is the most important renewable natural resource — food grows in it.
Types of Soil in India:
| Soil Type | Where Found | Characteristics | Crops |
|---|
|---|---|---|---|
| Alluvial | Indo-Gangetic plain, river valleys, coastal | Most fertile, good water retention | Rice, wheat, sugarcane, cotton |
|---|---|---|---|
| Black/Regur | Deccan Plateau (Maharashtra, MP, Gujarat) | High moisture retention, self-ploughing, rich in Ca/Mg | Cotton (best), jowar, linseed |
| Red and Yellow | Eastern and Southern India | Red due to iron oxide, poor in nitrogen | Rice, wheat, millet on fertile patches |
| Laterite | Western Ghats, NE hills, Odisha, Chhattisgarh | Formed by leaching (heavy rain washes nutrients), acidic, poor in nutrients | Tea, coffee, cashew (after treatment) |
| Arid/Desert | Rajasthan, Gujarat | Sandy, poor in nutrients, high salt | Drought-resistant crops with irrigation |
| Forest soil | Mountain regions | Coarse, less fertile, acidic in upper slopes | Tea, coffee, spices |

PYQs
2023: Distinguish between potential resources and stock resources.
Potential resources: available in a region but not yet used due to lack of technology or capital (e.g., wind energy in Rajasthan, uranium in Ladakh). Stock resources: those that have been assessed for use but due to lack of technology cannot be utilised (e.g., hydrogen as fuel — exists but technology not yet cost-effective at scale).
2022: Why is resource planning essential in India?
India has unequal distribution of resources — some states are mineral-rich but poor, others have human resources but lack minerals. Resource planning prevents over-exploitation, ensures sustainable use, and makes sure development reaches all regions. Without planning, resources are wasted, degraded, or only benefit some people.
2021: What is black soil? State its characteristics and the crop best suited for it.
Black soil (Regur/Cotton soil) is found in the Deccan plateau. Characteristics: high moisture retention, deep cracks when dry (self-ploughing), rich in calcium, potassium, and magnesium but poor in nitrogen. Best suited crop: cotton (also called black cotton soil). Also supports jowar, linseed, and sugarcane.
MCQ Practice
Q1. Alluvial soil is most commonly found in: (A) Deccan plateau (B) Eastern coast (C) Indo-Gangetic plain (D) Rajasthan → C
Q2. Laterite soil is formed by: (A) volcanic activity (B) leaching (C) wind deposition (D) glacial action → B
Q3. Which soil type is known as "self-ploughing soil"? (A) Alluvial (B) Red (C) Black/Regur (D) Laterite → C
Q4. Resources owned by the community are called: (A) national (B) potential (C) common property (D) international → C
Q5 (Hard). The fact that Rajasthan has vast wind and solar energy potential but it remains largely untapped makes it an example of: (A) stock resource (B) developed resource (C) potential resource (D) reserve resource → C
