Guinea, in West Africa, has been hosting hundreds of thousands of refugees from Liberia and Sierra Leone since the early 1990s. When the Secretary General of the United Nations, Mr. Annan, visited Guinea he was impressed by the efforts made to host all these refugees, but he was also shown the environmental impacts of this. He asked UNEP (United Nations Environment Programme, the principle environment body of the United Nations) to assist Guinea in assessing the environmental impacts of the refugees in Guinea. This website gives an overview of UNEP’s progress in the assessment project.
