[1] The Southern African Regional Science Initiative (SAFARI 2000) was a major surface, airborne, and spaceborne field campaign carried out in southern Africa in 2000 and 2001 that addressed a broad range of phenomena related to land-atmosphere interactions and the biogeochemical functioning of the southern African system. This paper presents a thematic analysis and integration of the Journal o...

The histories of the two swine fevers in southern Africa differ widely. Classical swine fever (hog cholera) has been known in the northern hemisphere since 1830 and it is probable that early cases of ‘swine fever’ in European settlers’ pigs in southern Africa were ...

The present article is a review of a palaeobiogeographic analysis of Jurassic Ostracods from East Africa, India and Madagascar and includes also some general remarks on palaeobiogeography, biodiversity and Ostracod ecology.The palaeobiogeographic study shows the high significance of this microfossil group for the reconstruction of palaeogeographic processes, particularly plate tectonic developm...

BACKGROUND Pretreatment drug resistance in people initiating or re-initiating antiretroviral therapy (ART) containing non-nucleoside reverse transcriptase inhibitors (NNRTIs) might compromise HIV control in low-income and middle-income countries (LMICs). We aimed to assess the scale of this problem and whether it is associated with the intiation or re-initiation of ART in people who have had pr...

To the Editor: Ehrlichia ruminantium, the causative agent of heartwater, is transmitted by Amblyomma spp. ticks. Amblyomma variegatum ticks, which are found in the Caribbean and sub-Saharan Africa, except in certain areas of southern Africa, are major vectors of E. ruminantium (1–3). A. lepidum is also an important vector of heartwater, especially in eastern Sudan (4). However, few epidemiologi...

The present international approach to management of transboundary animal diseases (TADs) is based on the assumption that most can be eradicated; consequently, that is the usual objective adopted by international organizations concerned with animal health. However, for sub-Saharan Africa and southern Africa more particularly, eradication of most TADs is impossible for the foreseeable future for ...

Livelihoods in southern Africa are in crisis. One of the worst ever food crises has hit the region, with over 14 million reported to be at risk. Newspapers carry appeals from charities for support, and TV images of food queues and malnourished children are commonplace. Yet, southern Africa is the region where the development success story was supposed to unfold. This was the bread basket of the...

Projections show that the effects of climate change in Africa will not be uniform over the region. The region is extremely vulnerable to the impact of climate change because of poverty, a high pre-existing disease burden, fragmented health services and existing water and food insecurity. Despite the consensus that locally relevant information is necessary to inform policy and practice related t...

Regional differences in neurovirulence have been documented among subtype/clade-C HIV-1 isolates in India and Southern Africa. We previously demonstrated that a C31S substitution in Clade-C Tat dicysteine motif reduces monocyte recruitment, cytokine induction and direct neurotoxicity. Therefore, this polymorphism is considered to be a causative factor for these differences in neurovirulence. We...
