How agriculture, minerals, industry and transport are distributed across India — and why.
Economic Geography studies the spatial distribution of economic activities — agriculture, mining, industry and transport — and the physical/human factors that explain that distribution. It is a bridge topic connecting Physical Geography (climate, soil, relief) to the Economy syllabus (sectoral composition, regional disparity).
India's agricultural pattern is closely tied to soil type, rainfall and irrigation access:
Historic industrial concentration follows raw material and port access — the Hooghly Industrial Belt (jute, engineering, around Kolkata), Mumbai-Pune belt (textiles, chemicals, automobiles), Chota Nagpur belt (iron and steel, around Jamshedpur, Bokaro, Durgapur), and, more recently, IT/services-led corridors around Bengaluru, Hyderabad and the National Capital Region, reflecting a shift towards knowledge-economy geography.
India's transport geography spans an extensive rail network (one of the largest in the world under Indian Railways), the National Highways network (increasingly expanded under the Bharatmala programme), major ports (12 major ports including Mumbai/JNPT, Chennai, Vishakhapatnam, Kandla/Deendayal), and a growing civil aviation network under regional connectivity schemes like UDAN.
Prelims frequently tests matching crops/minerals to their leading producer states and industrial belt names. Mains rewards linking economic geography to regional development disparity and policy responses (e.g. why mineral-rich eastern states remain relatively less industrially developed despite resource abundance — the "resource curse" debate).
