The Kavango-Zambezi Transfrontier Conservation Area (KAZA TFCA) in southern central Africa covers an area of c. 400,0001 km2 – an area slightly larger than that of Zimbabwe, and 1.6 times the size of Great Britain. The Victoria Falls forms a well known central point in the TFCA and is near the meeting point of four of the five participating countries (Angola, Botswana, Namibia, Zambia, and Zimbabwe). Two major river basins, the Zambezi and the Okavango contribute major wetlands, including the Okavango Swamps, to the generally flat to gently undulating KAZA-TFCA landscapes. In palaeo-evolutionary terms the two basins are closely interlinked – a feature that has influenced the biodiversity of the area and which has important implications for wetland species and their conservation.
