Rainfall variability over southern Africa
Southern Africa is subject to high inter annual rainfall variability and the factors influencing southern African rainfall are not fully understood. The variability has been linked with various sea surface temperature anomalies (SSTAs) in each of the three major ocean basins as well as variability …

Bantu pottery of Southern Africa
The Bantu people of Southern Africa entered this region from the North in successive migratory waves and advanced to the regions which they, now inhabit. The first of the immigrants crossed the Zambezi at about the beginning of the Christian era. Pottery of a type belonging to the earliest Iron Age …

Decadal rainfall variability over Southern Africa
Southern Africa is a region of vulnerability, with high seasonal and interannual rainfall variability combined with rain-dependent agriculture. This variability is underpinned by influences from ENSO and other oceanic forcing, and known to exhibit quasi-decadal variability at 16-20 years (Tyson, …

An assessment of resettlement programmes in Southern Africa
… programmes in Zimbabwe, Namibia and South Africa aim to provide secure access to natural resources and infrastructure for landless people within rural areas, in order for them to achieve self sufficient livelihoods through the production of agriculture. Resettlement programmes are a …

Intra-seasonal oscillations of convection over southern Africa
… over the summer rainfall region of South Africa. Spectral analysis of a precipitation minus evaporation index (P-E) compiled from 16 rainfall stations in the western Transvaal region of South Africa has shown that two dominant spectral peaks occur in the water budget or convection as …

Systematics of the Gracilariaceae (Rhodophyta) of southern Africa
Southern Africa has an extremely rich and diverse seaweed flora with a wide variety of marine habitats. Increased commercial interest in these seaweed resources has been the stimulus for biodiversity studies. The Gracilariaceae (Rhodophyta) has emerged as one of the families that possess economic …
