This article looks at the changes which are taking place in the Syrian semi-nomadic bedouin flocks' feeding and migration patterns, and the historical reasons for these changes.
Recent arguments have stated that the new livestock development policy will carry a high social cost, that the reality of range degradation in Botswana has been ignored, and that there is no basis for assuming that de-stocking would decrease the productivity of rangeland.
A useful debate is developing over carrying capacity and the degradation of communal rangelands in sub-Saharan Africa.
Paper attempts to dispel some of the confusion surrounding the application of the range degradation concept in Botswana. It has three objectives. First, to present the current thinking of range ecologists vis-a-vis range degradation.
The paper begins with a literature review of the basic theories which underpin range science. Two major approaches for determining carrying capacity (CC) are described, animal or plant oriented.
This thesis examines water quality status and deterioration in the Upper-
Athi-Nairobi sub-catchments which covers an area of 1154.4 km2 with an annual
discharge rate of 99242 m3/year (9.9 X 104 m3/yr). It is based on field and
laboratory analysis of water quality parameters.
This paper describes the environmental degradation that has occurred in Kenya since early this century, initially due to the introduction of plantation farming. Forests have been further targeted for farmland, fuel wood, building materials and hardwood species.
