The Kiribati Government wants people to eat healthy, traditional food, but their gardens are being ruined by salt water, says a local proponent.
Pelenise Alofa Pilitati holds public cooking demonstrations to teach people how to cook using beans, nuts and lentils.
She said the lessons were part of her "climate change adaptation programme" to help people whose gardens were threatened by tidal surges and sea-level rise.
Otherwise, "people live off rice and tinned food".
She said salt water was already seeping into the earth near her home, polluting the underground freshwater supply and affecting the roots of plants.
