More than half of Ayetoro, a coastal settlement in Nigeria’s Ondo state, has been lost to Atlantic tidal surges over the past two decades, with hundreds of homes, schools, and churches washed away. Residents describe the sea’s accelerated advance: on 15 February 2019 a retired midwife lost her shop, in 2023 a 79-year-old man lost his 10-room house, and the primary health centre and Happy City College now stand just steps from the shoreline, threatening immunisation programmes and education.
