About: The Sperrgebiet: Namibia's Least Known Wilderness

Many people helped compile The Sperrgebiet: Namibia's Least Known Wilderness, an environmental profile of the Sperrgebiet. The first step taken by the editors was to solicit a number of specialist reports from a variety of people who had worked in the Sperrgebiet or who were otherwise familiar with aspects of the history or environment of Diamond Area 1. This surprisingly rich assemblage of information was then condensed into its present form. The Sperrgebiet: Namibia's Least Known Wilderness presents information on the natural resources of the Sperrgebiet and the potential that the area holds.

It is intended to lay the basis for future planning and management, and to direct attention to the valuable historical and biological resources that remain largely unknown to the Namibian public and tourists. Because of the wide scope and large area covered in the profile, information is broadly based. It is not intended as an environmental assessment, although some impacts of current mining and other potential uses are highlighted. It should certainly not act as a substitute for any assessment of a development project that, by Namibian law, is required before commencement.

Any specific area that is targeted for prospecting, mining, agriculture, tourism or other development must therefore be investigated in more detail. Recommendations are given with the long-term, sustainable use of the natural resources in mind. The limited knowledge and awareness of the Sperrgebiet emphasizes a need for further work. This lack of information and appreciation of the area hampers decision-making and hinders planning. These deficiencies need to be addressed urgently to prevent irreversible loss of the potential that the Sperrgebiet holds for Namibia.
