Paper II

Story hook

In March 2024, in a green-field plot at Dholera Special Investment Region (Gujarat), the Tata-PSMC consortium broke ground on India's first commercial-grade semiconductor fabrication plant — a 28-nm logic fab with 50,000 wafer starts per month capacity, ₹91,000 crore investment. The Tata- PSMC ceremony was attended by the Prime Minister, the Chief Minister of Gujarat, the President of Powerchip Semiconductor Manufacturing Corporation (Taiwan), and the chief economist of the Ministry of Electronics and Information Technology. The location was anything but accidental. Dholera SIR sits on a flat, low-cost coastal plateau, 100 km from Ahmedabad's international airport, served by the new Mumbai-Ahmedabad-Delhi DFC, fed by a dedicated 750 MW solar park, and within 80 km of two future deep-water ports (Hazira, Pipavav).

That single decision — Tata semiconductor at Dholera — is a live demonstration of every classical and modern industrial location theory UPSC Geography Optional Paper II expects you to handle: Alfred Weber's transport-labour minimisation, Walter Isard's interregional input-output, Hotelling's locational duopoly, Krugman's New Economic Geography (1991), Porter's diamond model of clusters (1990), and Storper- Walker's labour-control regimes. India's industrial geography since 1956 — Hindustan Steel's Bhilai-Rourkela-Durgapur, then Maruti at Gurugram, then Bangalore IT cluster, now Dholera chips, Sri City automobile, Sanand auto — has been one long case study in evolving location calculus.

UPSC Geography Optional Paper II asks two distinct genres of industrial question: (a) location theory applied to specific Indian industries (iron-steel, cotton textile, sugar, petrochemicals, IT), and (b) regional industrial geography (eight industrial regions of India per Spate/Singh, plus the new PLI/SIR mega-zones). This file builds both.

Why this matters for UPSC

UPSC Geography Optional Paper II Section A carries at least one industry question every year since 2014; in 2017 and 2022 there were two industry questions in the same paper. Mains GS-III on infrastructure, GS-I on industrial development, and Essay also draw on industrial geography. Industry sits at the heart of India's regional inequality debate, the Mahalanobis controversy, the PLI strategy, and the manufacturing share question (target 25% of GDP by 2025; current 14%).
