Corridors and ring strategy
Framed explosive megacity growth
The Karachi Development Plan, prepared by the Karachi Development Authority with United Nations assistance from the early 1970s and extended in a later plan horizon to 2000, sought to structure the explosive growth of Pakistan's largest city and port. It proposed a framework of development corridors and ring roads, the decentralisation of employment, large serviced-land programmes for housing, and improvement approaches for the katchi abadis, the city's informal settlements.
The plan is a significant example of internationally assisted master planning for a rapidly urbanising postcolonial megacity, and its corridor-and-ring framework continues to underlie Karachi's road structure. Its partial implementation amid land speculation, institutional fragmentation and informal growth has made Karachi a much-cited case in critiques of comprehensive planning under conditions of weak governance.
