Commenting on how Singapore can strengthen its coastal defences to protect its shores from the rising sea level, SMU Associate Professor of Science, Technology and Society Winston Chow said that in addition to protecting Singapore's coasts with 'hard' infrastructure like seawalls, dykes, or polders along its exposed coasts, natural forms of defence should also be deployed. "We can also accommodate for sea-level rise using 'natural' coastal features, such as managing mangrove coasts that can potentially adapt to rising sea levels 'naturally' to protect against erosion," he said.
