Chapter 1: Geography - Complete Study Guide | NCERT Class 10 Notes & Questions 2025
Comprehensive Chapter Summary - Resources and Development Class 10 NCERT
Overview
- Chapter Purpose: Explains resources as everything in environment satisfying needs if technologically accessible, economically feasible, culturally acceptable. Involves interaction between nature, technology, institutions. Humans transform materials into resources. Fig. 1.1: Interdependent relationship. Not free gifts; function of human activities. Key Insight: Resources vital for survival, quality life; indiscriminate use leads to depletion, inequality, ecological crises. Sustainable development essential.
- Classification of Resources: (a) Origin: Biotic (living, e.g., flora/fauna), Abiotic (non-living, e.g., rocks/minerals). (b) Exhaustibility: Renewable (replenished, e.g., solar/wind), Non-renewable (finite, e.g., fossil fuels). (c) Ownership: Individual (private land), Community (village commons), National (minerals), International (ocean beyond EEZ). (d) Development Status: Potential (undeveloped, e.g., Rajasthan wind), Developed (utilized), Stock (known but not usable, e.g., water hydrogen), Reserves (subset of stock, extractable). Fig. 1.2: Classification flowchart.
- Expanded Relevance 2025: With global warming, focus on sustainable use; India’s resource planning addresses diversity/shortages. Update: Link to SDGs, Agenda 21.
- Exam Tip: Use figures for classification; distinguish renewable/non-renewable with examples.
- Broader Implications: Resources drive development but overexploitation causes crises; equitable distribution key for peace.
Development of Resources
- Problems: Depletion for greed, Accumulation in few hands (rich/poor divide), Ecological crises (global warming, ozone depletion, pollution, land degradation).
- Sustainable Development: Development without damaging environment, not compromising future needs. Rio Earth Summit 1992: 100+ heads signed Climate Change/Biodiversity declarations, adopted Agenda 21 for 21st-century sustainability.
- Agenda 21: UNCED declaration at Rio for global cooperation on environment, poverty, disease; local governments draw own Agenda 21.
Resource Planning
- Need in India: Diversity in resources; some regions rich (e.g., Jharkhand minerals) but deficient others (e.g., Ladakh water/infrastructure). Balanced planning at national/state/regional/local levels.
- Process: (i) Identification/inventory via surveying/mapping/estimation. (ii) Planning structure with technology/skills/institutions. (iii) Matching with national plans. India’s efforts from First Five Year Plan.
- Factors for Development: Availability alone insufficient; need technology, human quality, historical experiences. Colonization example: Rich colonies exploited due to invaders’ tech superiority.
- Conservation: Irrational use leads to problems; Gandhiji: Enough for need, not greed; against mass production. Club of Rome 1968, Schumacher “Small is Beautiful” 1974, Brundtland Report 1987 (“Our Common Future”).
Land Resources
- Importance: Supports vegetation, wildlife, human/economic activities; finite, use carefully. Relief: Plains (43%, agriculture/industry), Mountains (30%, perennial rivers/tourism/ecology), Plateaus (27%, minerals/fuels/forests). Fig. 1.3: Land under relief.
- Land Utilization: Forests; Not available (barren/waste, non-agri uses); Uncultivated (pastures, tree crops, culturable waste); Fallow (current/other); Net Sown Area (NSA), Gross Cropped Area (GCA).
- Land Use Pattern: 3.28 million sq km total; data 93% (NE states/J&K incomplete). NSA ~54% incl. culturable waste. Varies: Punjab/Haryana >80%, Arunachal <10%. Forest <33% desired (NFP 1952). Pastures decreased; consequences on cattle. Fig. 1.4: Pie charts 1960-61 vs 2019-20; marginal changes in NSA/forests.
Land Degradation and Conservation
- Causes: Deforestation, overgrazing (Gujarat/Rajasthan/MP/Maharashtra), Mining (Jharkhand/Chhattisgarh/MP/Odisha), Overirrigation (Punjab/Haryana/UP - salinity/alkalinity), Mineral processing dust, Industrial effluents.
- Measures: Afforestation, grazing management, shelter belts (arid areas), thorny bushes for sand dunes, mining control, effluent treatment.
Soil as a Resource
- Formation: Relief, parent rock, climate, vegetation, time; forces like temperature, water, wind, glaciers, decomposers; chemical/organic changes. Consists humus/inorganics. Fig. 1.5: Soil Profile (topsoil, subsoil, substratum, bedrock).
- Classification: Alluvial (fertile, northern plains/deltas; Bangar/Khadar); Black (regur, cotton; Deccan trap); Red/Yellow (iron diffusion; low rain areas); Laterite (leaching; acidic, tea/coffee); Arid (sandy/saline; irrigation cultivable); Forest (hilly, acidic/low humus).
- Soil Erosion: Denudation/washing; balance disturbed by human (deforestation/overgrazing) or natural (wind/water/glacier). Types: Gully (channels/ravines), Sheet (topsoil wash), Wind (loose soil). Defective farming worsens.
- Conservation: Contour ploughing, Terrace farming, Strip cropping, Shelter belts.
