The associate climate change co-ordinator for Palau says his country is desperate for ways to fight climate change.
Xavier Matsutaro is leading a team visiting Tonga to study an EU-funded project constructing foreshores in eastern Tongatapu.
Mr Matsutaro says the use of structures called groynes to trap sand and address coastal eroision is a concept that could be used in Palau.
He says they have used other methods to combat sea level rise and erosion in the past with mixed sucess.
"It's a new issue that we are faced with and so we are trying to think outside the box in how we can best deal with the issue. Obviously this won't be a permanent solution but it will at least buy us some time in that we can figure out what to do in terms of relocating our communities more inland."
