Climate trends in southern Africa

Orbital-scale climate forcing of grassland burning in southern Africa.

Although grassland and savanna occupy only a quarter of the world's vegetation, burning in these ecosystems accounts for roughly half the global carbon emissions from fire. However, the processes that govern changes in grassland burning are poorly understood, particularly on time scales beyond satellite records. We analyzed microcharcoal, sediments, and geochemistry in a high-resolution marine ...

Rabies in southern Africa.

The first confirmed outbreak of rabies in Africa, believed to have followed the importation of an infected dog from England in 1892, occurred in the eastern Cape Province of South Africa, and was brought under control in 1894. An unconfirmed epidemic of rabies in dogs occurred in western Zambia in 1901. By the following year the disease had apparently spread along a major trade route, to cause ...

Impacts and Adaptations to Climate Change in the Biodiversity Sector in Southern Africa

Global climate change is predicted to have substantial impacts on South Africa’s unique and prolific biodiversity but consequences for conservation planning (adaptation) are poorly described. Five distinct technical innovations were developed to address the issue of adaptation of biodiversity to climate change. A case study approach was used to develop tools to better understand the likely resp...

Pediatric Asthma in Southern Africa

Pediatric asthma has been well researched and actively managed in Southern Africa for many years. From the earliest study of asthma prevalence in 1979 revealing a significant rural – urban asthma gradient to more recent studies suggesting that asthma now abounds in all population and socio-economic groups, Southern Africa has been the subject of a significant number of publications relating to ...
