Update on Plans and Timeline for Projects to Protect Singapore's Coastlines from Impact of Climate Change

Speakers

Summary

This question concerns Mr Murali Pillai’s and Mr Saktiandi Supaat’s queries regarding updated timelines for sea-level rise and the progress of coastal protection projects like polders. Minister for Sustainability and the Environment Grace Fu Hai Yien stated that sea levels may rise by one metre by 2100 and noted that IPCC findings are being localised for adaptation planning. PUB has initiated site-specific studies for the City-East Coast, Jurong Island, and the North-West coast to evaluate polders, seawalls, and nature-based solutions. Furthermore, an ongoing pilot polder project at Pulau Tekong will guide the feasibility of using polders as a long-term coastal protection solution. The Government maintains a nimble approach to adaptation, ensuring measures remain responsive to evolving climate science and sea-level projections.

Transcript

40 Mr Murali Pillai asked the Minister for Sustainability and the Environment (a) in light of recent global climatic changes, whether there needs to be a revision to estimated timelines of sea-level rise that may affect Singapore in future; and (b) whether he can provide an update on the plan to build polders and implementation of other measures to deal with sea-level rise.

41 Mr Saktiandi Supaat asked the Minister for Sustainability and the Environment (a) whether the Ministry can provide an update on Singapore’s polder development project; and (b) how have the findings affected Singapore’s current plans and timeline to protect our coastlines from the impact of climate change.

Ms Grace Fu Hai Yien: Sea-level rise poses an existential threat to Singapore. By 2100, sea levels are expected to rise by up to one metre in Singapore due to climate change. We have started work to protect our coastlines to ensure that Singapore remains climate-resilient.

In developing coastal protection plans, the Government refers to the latest climate projections and risks, such as the recent findings by the Intergovernmental Panel on Climate Change (IPCC). These findings will be further localised to inform Singapore’s climate adaptation plans.

Coastal protection is a long-term and large-scale endeavour. Hence, even though there are uncertainties in climate projections, we have begun planning for coastal protection, beginning with the more vulnerable parts of our coasts. In May 2021, PUB, which is the national coastal protection agency, embarked on a site-specific study at the coastline of City-East Coast, which will consider possible protection measures, including the use of polders, seawalls as well as hybrid solutions that integrate nature-based elements such as planting mangroves. Similar studies to protect Jurong Island and the North-West coast will commence in 2022. These studies will develop coastal adaptation pathways and measures that are adaptive to climate uncertainties and the evolving climate science, drawing on international best practices.

HDB has also piloted a polder project at Pulau Tekong and its construction is ongoing. The learning points from this pilot will guide us on the feasibility of building polders as a coastal protection solution.

MSE will keep our adaptation measures nimble to account for the latest developments in climate science and projections of sea level rise. This will ensure that Singapore remains resilient to the long-term effects of climate change.
