- Abstract:
- Land degradation in semi-arid areas is a global problem which impacts on farmers and water supplies. In South Africa the 'desertification debate' is unresolved. Small headwater dams in the Karoo can be used to reconstruct erosion rates and to relate them to changes in stock numbers and climate. It is hypothesised that sediment yields to the dams have declined in the last fifty years with a substantial decline in stock numbers. Radionucleide, mineral magnetic and geochemical signatures will be used to examine the age and sources of sediments in the dams. Geophysical measurements together, with coring data, will allow reconstruction of temporal changes in sediment yields. The methodologies are widely applicable to similarly degraded areas.
