ORANGE–SENQU RIVER BASIN, Namibia
Forty years ago, Prosopis was introduced to areas of Namibia and South Africa as a fodder plant. However, it proved to be aggressively invasive in the drier, western areas of the Orange–Senqu River basin, outcompeting indigenous riparian vegetation, and impeding surface flow and groundwater recharge.
Prosopis is, however, a potentially valuable source of wood. Henk Kempen, who lives in Leonardville on the Black Nossob River, recognised that this pest could be turned into a profit and create much-needed employment, while addressing the environmental problems it causes. A small grant provided seed funding for community involvement and job creation through felling trees for charcoal, wood and construction timber.
Burning or treating the stumps of felled trees ensures, that they do not re-grow or coppice. Currently, his business keeps between 17 and 22 people employed and recently supplied wood used to reconstruct Swakopmund’s historical jetty.
