Nature-Based Infrastructure Key to Building Climate Resilience Across Asia

Recent catastrophic flooding in Nepal has underscored a pressing reality facing policymakers across the region: the protection offered by forests and water systems cannot be overlooked in climate adaptation planning. These natural barriers have historically shielded communities from extreme weather, yet degradation and mismanagement have left many areas increasingly vulnerable.

The emerging concept of "blue-green" infrastructure—encompassing wetlands, forests, rivers, and water retention systems—represents a paradigm shift in how governments approach disaster resilience. Unlike traditional concrete-based solutions, these nature-based approaches work with ecological processes to absorb excess water, stabilise soil, and regulate local climate patterns.

For policymakers across India and neighbouring nations grappling with intensifying monsoons and erratic weather patterns, implementing such strategies offers both environmental and economic advantages. Protecting existing forests, restoring degraded wetlands, and maintaining natural water courses prove considerably more cost-effective than post-disaster reconstruction while providing additional benefits including improved water security and biodiversity conservation.

Experts emphasise that a comprehensive policy framework integrating blue-green infrastructure into urban planning, agricultural management, and watershed development is essential. Countries must balance development imperatives with ecosystem preservation, viewing natural systems not as obstacles to progress but as foundational infrastructure for long-term community survival and prosperity in an increasingly unpredictable climate.
