The interface between local communities and transfrontier parks has received considerable attention, yet the utility of the transfrontier concept in developing livelihoods and environmental sustainability in southern Africa remains questionable. This paper argues that the benefits of transfrontier parks at regional, national and community levels cannot be overstated; neither should the problems be underestimated. Transfrontier parks may be viable alternatives in achieving development that is sustainable by protecting southern Africa's fragile environments, generating more funds and bringing significant and major improvements to the lives of the rural poor. At the same time, transfrontier parks raise issues of sovereignty of national governments, create complexity in governance processes and can lead to the needs of rural communities being sacrificed. Therefore, there is a need to find ways to reconcile conflictual and sometimes controversial circumstances in the establishment of transfrontier parks and, inquire further into the programmatic blueprints for transfrontier initiatives. Keywords: transfrontier, transfrontier parks, development, sustainability, conflicts.
