Island nation invests in innovative solutions to combat climate threats.
For decades, Singapore has expanded its territory through land reclamation, adding more than a quarter of its original size. However, with roughly one-third of the country less than 16 feet above sea level, rising seas now pose a serious threat to S$70 billion worth of prime real estate, including the Marina Bay financial district and industrial zones like Jurong Island.
To safeguard its future, the government has committed to spending S$100 billion over the next century on coastal protection. Already, S$5 billion has been allocated to a flood protection fund. Marina Barrage, a S$226 million dam, plays a crucial role in managing excess water, while 70% of Singapore’s coastline is already fortified with some form of barrier.
Ongoing initiatives include building storm surge barriers, raising coastal defenses, and developing high-ground infrastructure. Advanced computer models are being developed to predict the impact of sea-level rise and extreme rainfall. Nature-based solutions, such as mangrove restoration, are also being explored alongside traditional engineering measures.
Singapore is even adopting Dutch-style polders—low-lying land protected by sea walls and drainage systems. The first such project on Pulau Tekong will be completed by the end of 2024, adding 1% to the nation’s landmass.
With its unique economic and geographic challenges, Singapore’s climate resilience efforts are being closely watched by other coastal cities worldwide.
