Singapore Faces Billions in Coastal Damage from Rising Seas, Responds with $100B Coastal Defense Plan Combining Sea Walls and Nature
-
Singapore is vulnerable to sea level rise with 1/3 of the country less than 5m above sea level. Valuable coastal property worth billions is at risk.
-
The government plans to spend $100B over 100 years on coastal protections like sea walls, tide gates, and storm barriers.
-
Natural solutions like mangrove forests are also being used. Experiments combining mangroves and rock barriers are underway.
-
Singapore is reclaiming land below sea level using Dutch polder technology to create new usable land.

A 3 sq mile polder on Pulau Tekong will add 1% to Singapore's land mass by 2024 for military use.
