Abstract: Harsh sea-states and sea level rise brought about by climate change will exacerbate the risks of flooding and erosion on coastlines around the world. In recent years, nature-based solutions have been gaining popularity as coastal protection structures. Oyster reefs have been utilised in various parts of the world for their wave breaking ability, marine biodiversity enhancement and improvement of water quality, among many other benefits. This study is the first of its kind to assess the feasibility of oyster reefs in Singapore. Using 130 kg of discarded oyster shells, a pilot artificial oyster reef was created with the help of local restaurant partners, student volunteers, citizen scientists and other stakeholder groups. Over six months, the oyster reef not only enhanced the site’s biodiversity (species richness and diversity), unassisted oyster larvae recruitment also demonstrated its potential to be a self-sustaining coastal protection solution.
