This thesis discusses the sustainability of destocking as an intervention technique to reduce erosion in South Africa. Interventions to reduce erosion have been based on an equilibrium view on nature. This view supposes that the number of livestock should not exceed the carrying capacity of nature. Since the South African government believed the number of livestock did exceed the carrying capacity, it therefore decided to destock communal grounds. With reducing the number of cattle, the local people get more problems in making a living. It is therefore not a sustainable solution to reduce erosion. With this conclusion, the question remains which sustainable intervention strategies can be applied. In this thesis, the non- equilibrium theory is used in order to come to new, refreshing strategies. This perspective views nature as dynamic and changeable and show that it is better to let nature do its work. To get a better idea of alternative directions for future interventions a model is developed with four intervention-styles based on equilibrium and non-equilibrium viewpoints and on quality and quantity of livestock as dividing factors.
