Managing the spread of Prosopis invasive species, a case of Southern Namibia
Prosopis invasion has tremendous negative effects on biodiversity and water resource management in Southern Namibia. There are three Prosopis species in Namibia, with the most occurring one being P. glandulosa found in riverbeds and along dry water courses. These species are known to be aggressively invasive as they outcompete indigenous species. As with bush encroachment,…
Namibia could benefit from bush control
Bush encroachment has increased significantly in Namibia. The scale is alarming. It is estimated that more than 30 million hectares (30 per cent) of farmland are affected by bush thickening. This has negative impacts on some of Namibia’s key ecosystem services, such as livestock production, groundwater recharge and tourism, as well as biodiversity. The GIZ Economics…
Bush thinning principles and guidelines
All bush thinning or harvesting projects should be implemented with environmental consideration to avoid or curb any anticipated environmental damage. Bush thinning should therefore aim to leave a heterogeneous, mix of trees and bushes. A rule of thumb is to harvest only 30-35% of total available biomass (Smit et. Al 2015). Moreover, all protected plant…
