Caprivi wildlife-proof fence, Namibia. Veterinary cordon fences have been erected across southern Africa to prevent the movement of wild animals, especially buffalo, from wildlife areas to agricultural zones where cattle production is common.

The TFCA concept and current, internationally accepted approaches to the management of transboundary animal diseases (TADs) are largely incompatible. The present approach to the control of important TADs (such as foot and mouth disease, FMD), relies on the use of extensive fences to prevent movement of susceptible animals between areas where the disease occurs and areas where it does not, and to similarly restrict trade in commodities derived from these animals. This approach is incompatible with the vision of vast conservation landscapes, the longterm success of which depends largely upon the unrestricted movement of wildlife.
