Infrastructure Development: Balancing Growth with Resilience

Infrastructure is the backbone of urban life, yet coasal cities must build it under thee constant threat of natural hazards. Miami and Mumbai have taken different approvaches to o infrastructure, reflecting their different governance systems, financial capacities, andd risk profiles.

Mumbai: Informal Economy and Health Crisis

Mumbai 's urbanization is drisn by migration from poorer parts of India.
