PART 2 — Detailed Notes

Settlement Patterns

Key Term

Where do settlements form?

The location of settlements is determined by:

  1. Water availability: Nearly all ancient settlements are near rivers (Nile, Ganga, Indus, Mesopotamia, Yangtze, Thames)
  2. Fertile land: Agricultural societies settle where soil is good for farming
  3. Defence: Many historical settlements on hilltops, inside bends of rivers, on islands (Mumbai — originally islands; Delhi — on the Yamuna; Agra — Yamuna)
  4. Trade routes: Junctions of trade routes grew into towns (Varanasi, Agra, Lahore — all on ancient routes)
  5. Resources: Settlements near coal (Jharkhand), minerals, forests

Rural settlement patterns:

  • Nucleated (clustered): Houses close together; common in areas with limited water or where defence needed
  • Dispersed: Houses spread out; common in hilly areas or where land holdings are large
  • Linear: Along a road, river, or railway line

Urbanisation in India (Census 2011):

  • Urban population: 377 million (31.16% of total); Urban India = 3rd most populous urban population after China and USA
  • Census 2021 (delayed — expected data ~2025–26): Urban population estimated ~35–40%
  • Primate city: City far larger than the next city in a country — Delhi and Mumbai are India's "primate cities"

Transport Networks

Prelims trap: Smart Cities = 100 cities (AMRUT = 500; both June 25, 2015 — same date is a trap); PMAY-U verticals 2.0 = 4 (BLC + AHP + ARH + ISS; ISSR dropped and CLSS replaced — candidates often cite the 1.0 list); MPC = Article 243ZE (NOT 243S — that's Ward Committees; MPC = 243ZE for metropolitan areas); 74th Amendment = 1992 (73rd Amendment = same year, for Panchayats; both 1992); SVAMITVA = Ministry of Panchayati Raj (NOT MoHUA — urban housing is MoHUA; SVAMITVA is for village land = Panchayati Raj).

Exam Strategy

Prelims traps:

  • Golden Quadrilateral = 4 cities (Delhi, Mumbai, Chennai, Kolkata); ~5,846 km; NOT a pentagon or triangle
  • PMGSY = rural roads (to villages, not national highways)
  • NW-1 = Allahabad to Haldia (Ganga-Hooghly system); NW-2 = Brahmaputra — both frequently asked
  • India Post = world's largest postal network (by number of post offices) — NOT USA or China
  • DFC: Two dedicated freight corridors — Eastern and Western — separate tracks for freight trains
  • 95% of India's trade (by volume) = by sea — NOT railways or roads (weight/volume not value)
  • UDAN scheme = aviation + regional connectivity (Civil Aviation Ministry) — NOT rail scheme
