Coffee bushes support mosses, birds, flowering plants
Biologists Sileshi Nemomissa and Anteneh Shimelis from Addis Ababa University in Ethiopia say coffee shrubs have a positive impact on plant and animal diversity in deforested agricultural land and gardens, particularly if cultivated in the shade of large trees. Forest-grown coffee, however, had a negative ecological impact. More>>
Mozambican–South African carbon trading under scrutiny
African synthetic fuels producer Sasol has applied for carbon credits to replace South African coal with piped-in Mozambican natural gas, under the Clean Development Mechanism.

Circumcision a ‘risky’ HIV prevention method
A Kenyan study warns that the high risk of complications in both traditional and medical circumcisions in regions with limited post-operative care will negatively affect efforts to combat HIV through mass male circumcision campaigns.

Satellites keep an eye on crops
Satellite monitoring of Southern Africa predicts decreased maize yields due to dry weather in Angola, Malawi, Swaziland and Zambia, above average maize production in Botswana and normal yields in Lesotho, South Africa and Namibia. The programme, which uses remote sensing to assess factors such as crop growth and also forecasts sorghum and millet, plans to expand to West and East Africa this year. More>>

Nigeria doesn’t blink at glaucoma surgery
Ophthalmologists Adeyinka Ashaye and Opeyemi Komolafe from Ibadan’s University College Hospital conducted a year-long follow up study of eye surgery on glaucoma patients who risked blindness from the excess pressure inside the eye and found, despite risks, a considerable success rate using more modern techniques such as guarded filtration in operations.

Penicillin-resistant bacteria threatens car accident victims
Microbiologists from the Nigerian universities of Uyo and Calabar have found a high rate of bacterial infection in people injured in automobile accidents. Most of the microorganisms they identified were highly resistant to penicillin and a number of other antibiotics — suggesting drug choices should be made carefully if sensitivity tests are not available.
