The Okavango Delta, located in north western Botswana, is a renowned natural wonder of international biodiversity significance that also plays a key role in the economy of Botswana. A large inland delta, the sink of the Okavango River, the delta is listed as a wetland of international importance under the Ramsar Convention. The Okavango Delta Management Plan (ODMP) is being developed in order to ensure the delta's long term conservation and its provision of benefits to society. The ODMP project is trying to assess the fundamental linkages and interdependencies between the hydrological functioning of the Delta, its ecology and the economy these support. The World Conservation Union (IUCN) is supporting the development of the ODMP, as part of the Water and Nature Initiative in Southern Africa. This includes carrying out an economic valuation study of the Okavango Delta in conjunction with Botswana's Department of Environmental Affairs (DEA). The overall objective of this study is to determine the economic value of the environmental goods and services of the Okavango Delta in order to evaluate the implications of a number of management and resource allocation options for the area. The report also provides recommendations that have a sound economic basis, which will help ensure future sustainable use of the Okavango Delta. While this study is not comprehensive, it will provide much of the information required by building on the considerable existing volume of relevant work that has been carried out on the Okavango Delta.
