Among the ideas given by Prime Minister Lee Hsien Loong to sort out rising sea ranges throughout his 2019 National Day Rally was one which concerned reclaiming a collection of islands offshore from Marina East to Changi, connecting them up with barrages and creating a reservoir, comparable to Marina Reservoir.
Singapore has additionally already put in place some measures, together with the use of polders, that are tracts of land that lie beneath sea level and are reclaimed by the constructing of dykes, drainage canals and pumping stations.
There is an ongoing polder challenge on Pulau Tekong, led by the Housing and Development Board, that is greater than midway full and set to end by the finish of 2024.
Minister for National Development Desmond Lee mentioned final month that the challenge, the first of its form for Singapore, will assist the nation to acquire expertise in growing polders, which “could be an option for coastal protection and resilience against sea-level rise”.
There are additionally plans to construct infrastructure larger above the sea level. Professor Benjamin Horton, the director at the Earth Observatory of Singapore at the Nanyang Technological University, mentioned that Changi Airport, for instance, is constructing Terminal 5 at 5.5m above current sea level to defend in opposition to future rising sea ranges.
“We can further think about engineering advances that will enable buildings to float,” he added.
PUB’s coastal safety division is additionally different attainable options, with senior assistant director Sarah Hiong reiterating that it is “important to study all options, even long-term ones, comprehensively”.
Here are another options being studied by Singapore:
SEA WALLS AND ROCK REVETMENTS
Both are arduous buildings that defend in opposition to coastal erosion. At current, PUB says they line about 70 per cent of Singapore’s coastlines.
“Building sea walls around the entire Singapore is a simple and direct but not an entirely feasible solution, because we also have to consider the interactions between the land and sea,” mentioned senior engineer Eugene Lim from PUB’s coastal safety team.
For instance, this might embody pure coastal habitats, recreation and industries that require waterfront entry.
“It will also not be aesthetically pleasing for the public too. Try imagining having a great wall built around the entire coastline of Singapore,” he added.
NATURE-BASED HYBRID SOLUTIONS
Mr Lim mentioned PUB intends to discover hybrid options, which mix engineering options with nature-based parts, together with the planting of mangroves, seagrasses or vegetation.
A good thing about this selection, mentioned Mr Lim, is that it supplies a chance for Singapore to create habitats to improve biodiversity.
However, it won’t be attainable to rely solely on nature-based parts.
Taking mangroves for example, Associate Professor Koh Tieh Yong, a climate and local weather scientist from the School of Science and Technology at Singapore University of Social Sciences (SUSS), mentioned that when sea level rises, the larger seawater will nonetheless infiltrate mangrove lands.
“During a storm, mangrove tree roots serve to break up the waves and hold down the earth, thus reducing coastal erosion. In this way, mangroves can protect areas further inland until the sea rises beyond a level where even mangroves cannot thrive.”
Thus, there’ll nonetheless be a want to pair it with man-made buildings like sea partitions as the predominant answer to sea level rise, he mentioned.
Another draw back is that the majority of Singapore’s coastal land is wanted for residences, industries, maritime port, airport or leisure seashores and so can’t be changed by mangroves.
MULTIFUNCTIONAL COASTAL DEFENCES
Due to Singapore’s land shortage, multifunctional buildings resembling Marina Barrage, could be an excellent answer, mentioned Mr Lim.
The barrage not solely supplies a supply of water provide, it acts as flood management and even a venue for recreation — a “hot spot for families” to have picnics, fly kites and spend high quality time collectively, he mentioned.
One abroad instance that protects in opposition to sea level rise which Ms Hiong highlighted is the Katwijk underground parking storage in the Netherlands, the place a lot of the nation is beneath sea level.
Designed by the Royal institute of Dutch Architects, it was the winner of the Best Dutch Building of the Year in 2016.
Situated beside a well-liked seaside, the challenge is a automotive park that is not solely in a position to home 650 vehicles, but additionally performs a crucial function as a dyke to defend the small, eponymous city in opposition to future floods.
What is fascinating about the challenge, mentioned Ms Hiong, is that “you can’t even tell that it’s actually a coastal protection measure” as a result of it is hid inside a sand dune in order that it blends in with the beachfront.
“So this is an example that really inspired us… to build something that not only has such an important use for the nation, but also something that the public will actually come to enjoy,” she mentioned.
