(a) Industrial complexes of Western India and the impact of SEZ policy

Western India (Gujarat and Maharashtra) constitutes the country's pre-eminent industrial corridor. Its primary characteristics include a dominant petrochemical and refining nexus along the Hazira-Dahej-Jamnagar belt (Jamnagar has the world’s largest single-site refining complex) and the Mumbai-Thane-Trans-Thane belt, leveraging deep-water port proximity (Kandla, JNPT, Mundra) for imported crude and bulk chemical feedstock. Traditional industrial inertia persists through the historical cotton textile clusters of Ahmedabad and Surat, alongside specialized diamond cutting and polishing in Surat. Over recent decades, the region has transitioned from conventional manufacturing into high-technology segments, including active pharmaceutical ingredients (API), specialty chemicals, precision engineering, and automotive clusters (Sanand, Pune-Chakan), now being tied together by the Delhi-Mumbai Industrial Corridor and its Dholera node.

The enactment of the Special Economic Zones (SEZ) Act of 2005 transformed this landscape, building on Kandla, Asia’s first export processing zone (1965). Coastal SEZs, notably Mundra and Kandla, drove large-scale private capital formation, boosted merchandise exports, and integrated local production into global value chains. Unlike pre-SEZ industrial growth, which often relied on inland, state-developed industrial development corporation estates, the post-2005 model created hyper-integrated, privately managed coastal mega-enclaves. However, this generated severe externalities: contentious agricultural and pastoral land acquisition, severe coastal and marine ecological degradation (such as the loss of mangrove ecosystems in the Gulf of Kutch), and acute infrastructure stress on surrounding municipal nodes lacking commensurate civic capacity. The SEZ appeal also faded after MAT and dividend-tax exemptions were withdrawn in 2011–12 and the income-tax holiday closed to units starting after March 2020, and many notified zones in the region were never made operational, while GIFT City’s IFSC has become the region’s new special zone for finance.

(b) Emergence of linguistic regions and states

Linguistic regionalism originated as an anti-colonial mobilization strategy, formalized in the 1920 Nagpur Session of the Indian National Congress through Linguistic Provincial Committees. Post-independence administrative anxieties over national unity led the Dhar Commission (1948) and the JVP Committee to caution against linguistic remapping. However, the martyrdom of Potti Sriramulu forced the creation of Andhra State (1953), precipitating the Fazal Ali Commission and the subsequent States Reorganisation Act of 1956. This established language as the primary basis of state boundaries, later leading to the bifurcation of Bombay State into Maharashtra and Gujarat (1960) and of Punjab into Punjab and Haryana (1966).

While linguistic reorganization enhanced administrative efficiency, deepened democratic participation, and stabilized the federal compact by aligning vernacular languages with provincial governance, it did not eliminate intra-state developmental inequalities. Over time, persistent economic neglect within linguistically unified territories spurred second-generation statehood demands rooted in developmental backwardness rather than language. This culminated in the creation of Chhattisgarh, Jharkhand, and Uttarakhand in 2000, and the bifurcation of Andhra Pradesh to form Telangana in 2014, while regional autonomy demands such as Vidarbha and Gorkhaland continue to test the federal framework.

(c) Drivers of urban sprawl and transport-led expansion

Urban sprawl across major metropolitan regions (Delhi NCR, Mumbai, Bengaluru, Hyderabad) is driven by steep land price gradients between city cores and peripheries, chronic shortages of affordable urban housing, speculative real estate investment, and unabated rural-to-urban migration. Furthermore, weak master plan enforcement and the outward relocation of land-intensive or polluting industries due to inner-city zoning restrictions have accelerated fragmented, leapfrog development across peri-urban fringes.

Large-scale transport investments have actively enabled this spatial dispersion. Peripheral expressways (Mumbai-Pune Expressway, the 158 km Hyderabad Outer Ring Road), sea links such as the Atal Setu (2024) opening Navi Mumbai and Uran, orbital ring roads, and rapid transit networks (Delhi NCR Metro and RRTS corridors, Bengaluru Namma Metro extensions) drastically compress travel times. While intended to decongest urban cores, these corridors convert distant agrarian hinterlands into viable commuter zones. In the absence of integrated land-use planning, transport investments inadvertently stimulate low-density, automobile-dependent ribbon developments that outpace basic municipal infrastructure like piped water and sewage networks.
