(a) Historical morphology of Indian towns and the first planned city after independence

Urban morphology is a town's physical form: its plan, street pattern, land use and buildings. In Indian towns, successive historical periods have left distinct layers.

Historical stages

• Harappan (c. 2600–1900 BCE): Mohenjo-daro, Harappa and Dholavira were planned, with a citadel, a lower town, grid streets and covered drains.
• Early historic: fortified river capitals such as Pataliputra. The Arthashastra prescribed a walled grid with occupational zones.
• Temple towns of the south: Madurai and Srirangam grew as concentric rings of streets around the temple core.
• Medieval Indo-Islamic: Shahjahanabad (Delhi, 1639–48) set a planned fort, the Jama Masjid and the Chandni Chowk axis within an organic mesh of mohallas and lanes.
• Rajput grid: Jaipur (1727), planned for Sawai Jai Singh II by Vidyadhar Bhattacharya, has a grid of blocks and wide bazaars.
• Colonial dualism: presidency towns had a fort with a "white town" and a "black town". Civil lines, cantonments and hill stations formed low-density enclaves beside congested native towns. New Delhi (Lutyens and Baker) brought a radial imperial plan.

Chandigarh: the first planned city of independent India

Chandigarh was built as Punjab's capital after Lahore went to Pakistan. Albert Mayer and Matthew Nowicki drew the first plan, and from 1951 Le Corbusier's team, including Pierre Jeanneret, Maxwell Fry and Jane Drew, gave it its final form.

• Organic metaphor: the Capitol Complex is the "head", Sector 17 the "heart", the Leisure Valley the "lungs" and the roads the "circulation".
• Sector as neighbourhood unit: each sector, about 800 m × 1200 m, is self-contained, with its own school, market and green spine.
• Hierarchy of roads (the 7 Vs): from V1 regional arteries down to V7 footpaths, separating fast and slow traffic.
• Capitol Complex: the Secretariat, High Court and Assembly stand against the Shivaliks. Since 2016 they have been part of a UNESCO World Heritage listing.
• Green and blue structure: Sukhna Lake, the Rock Garden, and a periphery belt protected by a 1952 Act against sprawl.

Some accounts name Bhubaneswar, planned by Otto Koenigsberger from 1948, as the first planned city of independent India; Chandigarh (1951) is the more widely cited example.

Historic towns grew as dense, organic, mixed-use cores. Chandigarh introduced modernist, zoned, low-density planning, which Gandhinagar and Navi Mumbai later followed. Critics point to its low density, car-oriented layout and the unplanned growth of Panchkula, Mohali and villages beyond the periphery.

(b) Health as an outcome of physical setting, cultural traits and ecological connection

Medical geography sees health as the product of a "triangle of human ecology": habitat, population and behaviour interact through ecological links such as vectors, water and food.

• Physical setting: climate, relief, soil and water chemistry set the base. Excess fluoride in groundwater causes fluorosis in Nalgonda and parts of Rajasthan. Arsenic in the aquifers of the Bengal delta causes arsenicosis. Iodine-poor soils made the sub-Himalayan belt a goitre zone.
• Cultural traits: diet, hygiene, housing, occupation and social norms decide exposure. Heavy consumption of khesari dal caused lathyrism in Chhattisgarh and eastern Madhya Pradesh. Biomass cooking fuel causes indoor air pollution, open defecation spreads diarrhoea, and gender norms restrict women's nutrition.
• Ecological connection: vectors and hosts link the two. Japanese encephalitis around Gorakhpur links paddy fields (breeding ground for Culex mosquitoes), pig-rearing and ardeid birds. Kyasanur Forest Disease in Karnataka's Western Ghats spread when forest clearance brought people, cattle and ticks into contact. Kala-azar in north Bihar is tied to damp mud houses that harbour sandflies. Forest malaria afflicts tribal Odisha and Chhattisgarh.

Interaction: the three factors reinforce each other. Among central Indian tribes, the sickle-cell trait is a genetic adaptation to malarial ecology, and endogamy concentrates it. In urban slums, crowding spreads tuberculosis while stored water breeds Aedes and dengue. Health planning must therefore be place-based, through mapping of endemic zones and a "One Health" approach.

(c) Regional rapid transit systems in India and how they address urban problems

A regional rapid transit system (RRTS) is a fast, high-frequency rail service linking a metropolitan core with satellite towns 50–100 km away, filling the gap between metro and intercity rail.

Major systems

• Delhi–Ghaziabad–Meerut Namo Bharat corridor (NCRTC): 82 km long, with a design speed of 180 km/h and an operating speed of 160 km/h. It opened in stages from October 2023, and the full corridor was inaugurated in February 2026 together with the Meerut Metro, which shares its tracks and stations within Meerut. The Delhi–Gurugram–SNB–Alwar and Delhi–Panipat corridors are the other priority lines.
• Suburban rail performs the regional role in Mumbai, Kolkata and Chennai (including its MRTS), and a Bengaluru suburban project is under way.
• Metro networks now run over 1,000 km across more than 20 cities, including Delhi (with the Airport Express), Mumbai, Bengaluru, Chennai, Hyderabad and Kolkata. Bus rapid transit systems such as Ahmedabad's Janmarg complement them.

How they address urban problems

• Congestion and travel time: they move large volumes on dedicated tracks. Delhi–Meerut becomes a trip of under an hour, which takes cars off the roads.
• Pollution and emissions: electric traction and regenerative braking cut vehicular emissions in the airshed of the NCR.
• Decongesting the core: fast links let people live in Meerut, Panipat or Alwar and work in Delhi, which spreads housing demand and eases land prices and slum growth.
• Transit-oriented development: the Metro Rail Policy and National TOD Policy (2017) encourage dense, mixed-use development around stations and multimodal integration.
• Balanced regional growth: satellite towns become counter-magnets, in line with the NCR Regional Plan.

Limits: these systems are capital-intensive, fares can be unaffordable, and last-mile connectivity is weak. Several metros run below projected ridership. Integration with buses, feeders and land-use planning is essential if these systems are to solve urban problems rather than relocate them.
