"Surface water resources (the Vaal River and its tributaries) in the Vredefort Dome World Heritage Site (VDWHS), South Africa, have been over extended and future development will rely solely on groundwater. Hence, being at a critical point in the water balance, groundwater resources in the VDWHS require careful management and protection to ensure sustainability and equitable access. An assessment of the geohydrological character of the VDWHS was therefore done in order to develop a groundwater resource management plan. Five groundwater resource management units were delineated and resource measures for each management unit were developed based on physical and anthropogenic attributes. Due to the importance of groundwater in the VDWHS, it was determined that geohydrology should play a major role in the alignment of the environmental, spatial and statutory development frameworks, in order to ensure good governance. A geohydrological-based land use management guideline and spatial development framework was developed to optimize the integration between the water sector, the environmental sector and land use and spatial planning sector. It was concluded that a geohydrological assessment needs to form the basis of all future land use management and spatial planning activities in the VDWHS."
