Drought is a frequent occurrence in contemporary sub-Saharan Africa, and the existence of periodic drought can be documented over hundreds of years. As a consequence of the routine rainfall shortages that affect them, agricultural and pastoral societies have developed a number of social institutions and mechanisms for bridging temporary food production shortfalls caused by drought. Drawing on the literature and field data from southeastern Kenya, this paper discusses a number of regular...

The Boksputs and Upington sequences of the Areachap Group, present along the eastern margin of the Namaqua mobile belt in southern Africa, contain amphibolites with chemical properties which suggest that they are the metamorphic products of arc related precursors. The amphibolites, which form the predominant rock type of the Jannelsepan Formation of the Areachap Group, are subdivided on mineralogical grounds into massive and pyroxene amphibolite. The massive amphibolite of the Boksputs...

A retrospective review was undertaken of the records of 725 children who attended the neurodevelopmental clinic at the Baragwanath Hospital in Soweto, South Africa. Most children presented at an early age (less than 2-6 years). The etiological factors were prenatal, 4 per cent; perinatal, 41 per cent; postnatal, 21 per cent. Seventy-one per cent of the perinatal factors were a result of birth related problems in full-term infants; only 22 per cent of this group were represented by premature...

SEVERE drought, the worst in 70 years, hit the Sahel and East Africa beginning in 1979. The lives of 14 million people have since been affected; hundreds of thousands have died from famine and related disease. The Sahara Desert continues to creep southward, claiming an area the size of New York State every decade. Human suffering in the hardest hit areas has received extensive media publicity. But the actual impacts extend much further into the African continent than the belt of land...

Veterinary science is, if not the last, at least one of the last sciences, the application of which has been recognized to be an important factor in the development of the stock-breeding resources of South Africa. The rough and ready methods used in the past to deal with plagues and diseases in stock have gradually given way to treatment based on scientific principles. As a result of this, the serious epizootics have been brought under control, and stock farming, which in earlier times was...

Nigerian primary school teachers have been observed to entertain a phobia towards educational technology by avoiding the use of equipment in teaching. This study was designed to investigate the causes of teachers’ apathy towards equipment and to verify possible links with technophobia. Results have yielded only...
