Jersey is set to spend £198 million over the next 100 years on sea defences to protect the coastline.
A new report says work is essential if homes and businesses are to be saved from rising seas and worsening weather.
Scientists have said that sea levels around the Channel Islands are rising by 3mm a year meaning by the end of the century sea levels could be half a metre higher.
The report says in the future some communities may have to be moved in a ‘settlement relocation’ process.
It highlights that new sea defences will need to be built in St Aubin’s bay. Despite previous defence work one in 20 homes in the area are at risk of flooding.
The north of the island will largely be left to nature as it is protected by large cliffs.
