This document discusses smart cities in India and related challenges and opportunities. It notes that urban populations are growing rapidly and will reach 900 million by 2050. Current urban infrastructure faces deficits, with many households lacking basic services. Significant investments estimated between $645 billion to $1.5 trillion will be needed through 2030 to modernize cities. The Smart Cities Mission aims to develop 100 cities by focusing on governance, infrastructure, quality of life, and economic growth. Selected cities will need master plans and use technology to improve services, transparency, and efficiency.
