India’s Urban Transition: Crossing the 500 Million Milestone and the Launch of Smart Cities 2.0

In response to these pressures, the Ministry of Housing and Urban Affairs (MoHUA) has launched 'Smart Cities 2.0'. Unlike its predecessor, which focused on foundational digital infrastructure in 100 cities, the 2.0 version emphasizes 'Climate-Resilient Urbanism.' Key pillars include integrated waste management systems to tackle the growing volume of urban solid waste, the expansion of affordable housing under revamped urban schemes, and the development of 'sponge city' infrastructure to mitigate the increasing frequency of urban flooding. From a policy perspective, the crossing of the 500 million threshold necessitates a rethink of urban governance. The financial and functional autonomy of Urban Local Bodies (ULBs), as envisioned in the 74th Constitutional Amendment Act, remains a critical bottleneck. For Smart Cities 2.0 to succeed, the government must focus on the devolution of powers and the enhancement of municipal revenue streams to ensure that cities can independently manage their growing populations. UPSC Relevance: This development is crucial for GS Paper I (Urbanization and associated issues) and GS Paper II (Government policies). It provides contemporary data for answers on migration patterns, the evolution of the Smart Cities Mission, and the challenges of sustainable urban development in the context of climate change and the 74th Amendment.
