A leading US environmental group is opposing the planned purchase of 325,000 hectares of land in Tanzania by an American company. Tanzania’s parliament is debating the government’s willingness to lease the land in the Rukwa and Kigoma regions to Agrisol Energy Tanzania Ltd, which is backed by a consortium of US investors. Opponents charge that the deal amounts to a 'land grab' that would result in the displacement of 160,000 refugees from Burundi, some of whom have lived on the land for 40 years.
