Resources and Agriculture

Overview

Resources and Agriculture forms a core geography segment in PSTET Paper II Social Studies, testing your understanding of how natural endowments translate into economic activities. Questions typically link resource types with their distribution, agricultural patterns with climatic zones, and industrial locations with raw material availability—especially in the Punjab context.

This topic bridges physical geography (climate, soil, water) with human geography (farming practices, industrial development). Expect 3–5 questions that may ask you to identify crop-climate relationships, locate industries, or explain Punjab's agricultural prominence. Mastery requires knowing both all-India patterns and Punjab-specific details—the Green Revolution story, the five doabs, and the state's agro-industrial base.

Key Concepts

• **Resources are classified by origin** (biotic/abiotic), **exhaustibility** (renewable/non-renewable), **ownership** (individual/community/national/international), and **development status** (potential/actual/stock/reserve).

• **Sustainable development** means using resources to meet present needs without compromising future generations—a recurring theme in NCERT and exam questions.

• **India's major soil types**: Alluvial (Indo-Gangetic plains, most fertile), Black/Regur (Deccan, cotton), Red (Deccan plateau fringe), Laterite (heavy rainfall areas, poor fertility), Arid/Desert (Rajasthan), Mountain (Himalayan).

• **Punjab's agricultural dominance** rests on alluvial soils of the five doabs, canal irrigation, tube-wells, and Green Revolution technology (HYV seeds, fertilisers, mechanisation).

• **Cropping seasons in India**: Kharif (June–October: rice, maize, cotton), Rabi (October–March: wheat, gram, mustard), Zaid (March–June: vegetables, watermelon).

• **Green Revolution** (1960s onwards) transformed Punjab and Haryana into India's "food bowl," dramatically raising wheat and rice yields but also causing groundwater depletion and soil degradation.

• **Industries depend on raw materials, power, labour, market and transport**; agro-based industries (textiles, sugar, dairy) cluster near agricultural zones; mineral-based industries (iron-steel) near ore deposits.

• **Punjab's industries**: Textiles (Ludhiana—hosiery capital), sports goods (Jalandhar), hand tools (Jalandhar), dairy (Verka brand), agro-processing (rice mills, flour mills).

Formulas / Key Facts

| Fact | Detail | |------|--------| | India's rank in agriculture | 2nd largest agricultural land; employs ~42% workforce | | Punjab's contribution | ~2% of India's area but contributes ~15–20% of wheat, ~10% of rice to central pool | | Five Doabs of Punjab | Bist (Beas–Sutlej), Bari (Beas–Ravi), Rechna (Ravi–Chenab; now mostly in Pakistan), Chaj, Sindh Sagar (latter two in Pakistan) | | Major Punjab crops | Wheat (rabi), Rice (kharif), Cotton, Sugarcane, Maize | | Irrigation in Punjab | ~98% of cultivated area irrigated; tube-wells + canals | | Major minerals of India | Iron ore (Jharkhand, Odisha, Chhattisgarh, Karnataka), Coal (Jharia, Raniganj), Bauxite (Odisha), Mica (Jharkhand–Bihar belt) | | Punjab minerals | Limited; some limestone, silica sand—hence agro-based industries dominate | | Largest irrigation canal in India | Indira Gandhi Canal (Rajasthan) |
