An analysis of insecticide-impregnated bednet usage in 40 African countries over seven years, using the Global Rural Urban Mapping Project, has identified poverty-stricken Nigerian children as a priority for the rollout of free bednets to prevent malaria. Other priority countries include Cameroon, the Democratic Republic of Congo, C

THE global price of basic food commodities and products has increased rapidly over the past three years resulting in increased food insecurity. In Africa, for example, social cohesion, peace and stability, as well as the encouraging economic gains among others, are at risk.

Some countries in West Africa are considering the potential adoption of insect resistant cotton. Burkina Faso has already approved commercial cultivation of this technology. This paper presents the results of a socio economic impact assessment of the potential adoption of insect resistant cotton in West Africa using an augmented economic surplus model to consider risk and parameter uncertainty.

Climate change in Africa is expected to lead to a higher occurrence of severe droughts in semi-arid and arid ecosystems. Understanding how animal populations react to such events is thus crucial for addressing future challenges for wildlife management and conservation. We explored how gender, age, mother's experience and family group characteristics determined calf survival in an elephant population during a severe drought in Tanzania in 1993. Young males were particularly sensitive to the drought and calf loss was higher among young mothers than among more experienced mothers.
