This project aims to elucidate how sensitive and to which extent soil properties respond to different rangeland management in the grassland and savannah biome of semiarid South Africa, and to figure out to which degree changes of the ecosystems are perceived and caused by farmers’ decisions. We hypothesise that both ecosystems respond differently to rangeland degradation: in the savannah biome bush encroachment leads to an improvement of the soil quality, whereas in grasslands degradation of the soils proceeds with intensified management.

该项目旨在阐明南非半干旱草原和稀树草原生物群的土壤性质对不同牧场管理的敏感度和程度，并弄清农民的决定在多大程度上影响和导致了生态系统的变化。我们假设两个生态系统对牧场退化的反应是不同的：在稀树草原，灌木入侵导致土壤质量的改善，而在草原，土壤退化是通过强化管理进行的。
