 Emerging Infectious Diseases: Canine rabies ecology in Southern Africa.(PERSP... @ HighBeam Research   (Site not responding. Last check: 2007-10-11)
In southern Africa, rabies virus affects many host species, but rabies cycles are sustained by carnivore hosts (5,6), particularly by canine species (family Canidae), which are the focus of this paper, and by mongooses (family Herpestidae) (5,7), which will not be considered here.
In southern Africa, jackals (C. adustus, C. mesomelas) are also hosts, although their role has been controversial; some studies indicate that they can support rabies cycles (8), and other studies indicate that they cannot maintain rabies independently of the disease cycle in dogs (9-12).
The ecology of many ecosystems has changed dramatically in recent centuries because of the increase in human populations, the introduction of large-scale commercial agriculture, urbanization, loss of biodiversity within the human biosphere, and other changes.

 Charcoal ecology Africa
In 2000, nearly 470 million tons of wood were consumed in homes in sub-Saharan Africa in the form of firewood and charcoal, more wood per capita than any other region in the world.
The results of the study show that the best situation in Africa would be to transition from biomass fuels to petroleum-based fossil fuels such as kerosene and liquid propane gas, which can prevent between 1.3 and 3.7 million premature deaths, depending on the speed of transition.
"Most charcoal is produced in Africa by one or two guys going out in the woods, almost always without a permit and on somebody else's land, cutting down a tree or two, chopping it up, lighting it, covering it with dirt, and then hovering around it for 2-4 days while it becomes charcoal," Kammen said.

 Eroding the Commons - Politics of Ecology in Kenya
Eroding the Commons examines Baringo’s efforts to contend with the problems of erosion and describes how they became a point of reference for similar programs in British Africa, especially as rural development began to encompass goals beyond economic growth and toward an accelerated transformation of African society.
It provides an excellent focus for the investigation of the broader evolution of colonial ideologies and practices of development.
Anderson (Univ. of London), author of articles on African ecology, first "reconstructs pastoral landuse patterns of the nineteenth century to illustrate that the Baringo lowlands formed part of a wider ecological system, seasonally exploited by transhumant herders."

Can you speak further on the issue of GMO and its potential impacts on the ecology of east africa in particular.
Also, as you probably know, there is a great deal of debate and division of opinion as to whether GMO's will have a negative or positive impact on the ecology in countries such as the USA.
However, in my view it is unlikely that there will be a very large-scale use of GMO's in east Africa in the near future so that the potential impact on the ecology will be marginal.
