domestic stock grazing systems for commercial purposes to a continuous grazing system for large-scale wildlife management by a conservation entity is a great opportunity to learn about the complex responses of ecosystems to changes in land management .

In planning to develop an environmental observation research platform , NRF- SAEON collated relevant information on the area in a comprehensive environmental baseline report ( Milton et al . ( 2020 ). Using available information and possible future land-use scenarios , Van der Merwe et al . ( 2021 ) developed a conceptual model predicting trajectories of change under these scenarios and the factors influencing them ( Figure 2 ).
NRF-SAEON aspires to investigate the changes taking place in the larger SKA landscape and invites collaboration with researchers already present in the landscape , for example , the South African Radio Astronomy Observatory ( SARAO ) and SANParks , as well as researchers from a diversity of fields from other organisations wishing to contribute to our understanding of Karoo rangelands .
