Protecting Coasts, Protecting Lives: Surat’s Climate Resilience Breakthrough

Why It Matters

The seawall safeguards millions, protects critical infrastructure, and demonstrates a replicable climate‑resilient model for coastal economies.

Key Takeaways

• Surat builds Dumas Seawall to shield against rising sea levels.
• Project combines nature‑based design with climate‑responsive engineering for coastal protection.
• Expected to protect half of Surat’s 8 million residents by 2050.
• Funded by UNEP, ADB, and Global Environment Facility.
• Model can be replicated across India and South Asia.

Summary

Surat, Gujarat, is constructing the Dumas Seawall, a large embankment designed to protect the city’s coastline where the Tapti River meets the Arabian Sea.

The project responds to escalating flood risk: 2024 monsoon floods displaced thousands, and a study projects four million residents—half the city’s population—could be affected by sea‑level rise by 2050. The seawall integrates nature‑based solutions and climate‑responsive engineering to curb erosion, flooding, and saltwater intrusion.

Backed by the Sustainable Cities Integrated Program, the initiative is funded by UNEP, the Asian Development Bank and the Global Environment Facility. Officials highlight ancillary benefits such as boosted tourism and new economic activity once the barrier is in place.

If successful, the Dumas Seawall offers a scalable template for other rapidly growing coastal cities across India and South Asia, marrying development goals with climate adaptation and reducing future disaster costs.

Original Description

In Surat, rising seas and stronger storms are putting a fast-growing coastal city at increasing risk.

The Dumas Sea Wall Project is helping to protect vulnerable coastlines through a combination of climate-resilient infrastructure and nature-based solutions. By reinforcing embankments, preserving mangroves, and integrating green public spaces, the project is reducing flood risks while supporting tourism and local livelihoods.

Designed with sustainable materials and minimal impact on the surrounding ecosystem, it shows how cities can adapt to climate change while working with the environment.

Building resilience is not just about defence—it’s about creating stronger, more sustainable coastal communities for the future.
