Explain the impact of Jawahar Lal Nehru Urban Mission on the challenges of urban development in India.

Urban Development Challenges in India and the Strategic Role of JNNURM:

1. Core Urban Development Challenges:
   • Rapid demographic urbanization outpacing municipal capacities, proliferation of informal slums, critical deficits in sewage treatment, and vehicular traffic paralysis.
2. Strategic Architecture of JNNURM (Launched December 2005):
   • A landmark national urban renewal mission across 65 mission cities combining capital infrastructure financing with municipal governance reforms.
   • Two Principal Sub-Missions:
     1. 1. Urban Infrastructure and Governance (UIG): Upgrading municipal water supply pipelines, storm-water drainage networks, and mass transit (BRTS).
     2. 2. Basic Services to the Urban Poor (BSUP): In-situ shelter rehabilitation, community toilets, and secure civic entitlements for slum populations.
   • Legacy: Laid the institutional foundation for succeeding flagship missions including Smart Cities Mission, AMRUT, and PMAY-Urban.
