Climate Change Adaptation through Blended Finance Models for Urban Flood Resilience in India: Assessing Viability Gap Funding and Performance Linked Guarantees in Smart Drainage Systems
Abstract: Urban flooding is an increasing climate adaptation challenge in Indian cities due to extreme rainfall, rapid urbanization, and degraded drainage systems. This study examines how blended Public-Private Partnership models can improve urban flood resilience through smart drainage infrastructure. It focuses on Viability Gap Funding and performance-linked operation and maintenance guarantees as key financial instruments. Using policy analysis and case studies from Kolkata, Chennai, Nagpur, and Bengaluru, the study evaluates financial feasibility and resilience outcomes. Results show that VGF support reduces capital burden and improves project viability, while performance-linked guarantees lower operational risks and promote technology adoption. The findings suggest that blended PPP models can enable scalable climate-resilient infrastructure if supported by clear risk allocation, institutional capacity, and outcome-based contracting.
