An estimated 45 million hectares of Namibia are considered 'bush encroached': local bush species have turned once open savannah into thicket. Bush encroachment reduces grass growth, biodiversity and the water-holding capacity of the land, posing a problem for farming and conservation alike. Counter-intuitively, the bush also provides a huge opportunity - farmers looking to restore their rangelands can generate economic returns by joining the dynamic bush biomass industry.
