In the Maldives, A.I. Helps Rebuild Beaches Threatened by Rising Seas
An experimental system with origins at M.I.T. is being tested in the Maldives, using artificial intelligence to read coastal erosion patterns and redirect sand so it accumulates on beaches instead of washing away.
In the Maldives, where rising sea levels pose a direct threat to low-lying islands, an experimental technology is being tested to help preserve eroding beaches. The system, which traces its roots to the Massachusetts Institute of Technology, uses artificial intelligence to assess patterns of coastal erosion — the way waves and currents move sand along a shoreline.
Using this analysis, the technology aims to work with natural coastal processes rather than against them, encouraging sand to build up in place instead of being carried away by the sea. This differs from conventional approaches, where erosion often results in a steady, long-term loss of sand and shoreline.
The Maldives is one of the lowest-lying nations in the world, making it especially vulnerable to the effects of rising seas driven by climate change. Beach erosion there has consequences not only for residents but also for the tourism industry, which is a major part of the country's economy.
The experimental system represents an emerging category of technology-driven responses to coastal erosion, combining data analysis and artificial intelligence with physical interventions in natural processes. While the scale of its deployment and results are not yet widely detailed, the approach is being presented as a possible model for other island nations confronting similar climate-related challenges to their coastlines.
