ABSTRACT
Defining the geomorphology of a landscape in terms of regions can be problematic. The occurrence and distribution of landforms are not constrained by any human demarcations or political boundaries. Nevertheless, central southern Africa, here defined as the catchment of the Orange River and its major tributaries (Figure 1),
provides a reasonably well defined region in terms of its characteristic, but varied suites of landforms and landscapes. From a geomorphological perspective, what evidence has this region yielded which might contribute to our understanding of, in particular, late Quaternary environmental change in the region, and how might it continue to do so in the future?
