A small Native American tribe in Louisiana whose land has nearly vanished into the sea has moved a step closer to relocating its community further inland after authorities acquired new land for the move, part of a first-of-its-kind project.

The 515 acres (208 hectares) of farmland will be made available to members of the Biloxi-Chitimacha-Choctaw tribe and other inhabitants of the Isle de Jean Charles to relocate after their village was nearly wiped by erosion and rising seas.

"I'm happy that finally, after three years, we have property bought," Chantel Comardelle, the tribal executive secretary of the Biloxi-Chitimacha-Choctaw, said on Thursday.
