Results from this study show that the over-used but under-researched association between grazing and land degradation in the Kalahari has been oversimplified. In typical Kalahari conditions, the ecological changes that have been brought about by grazing cannot be linked with more fundamental changes in ecosystem function. Basic soil processes appear relatively unaffected by grazing pressure outside the sacrifice zone, and there is no evidence to suggest that the resilience of the system has been affected through soil degradation.

Carrying capacity (CC) is a term often talked about in relation to livestock in the communal areas (CAs). It is the source of much confusion. This discussion paper will hopefully clarify some of the issues and make the implications for the policy debate clearer. It is based on the preliminary findings of field work carried out in Zvisharane District during 1986 and 1987.

Library ResourceJanuary, 1990Zimbabwe, Sub-Saharan Africa
In their recent paper, de Leeuw and Tothill (1990) discussed the shortcomings of estimating carrying capacity (CC) of pastoral systems in Africa. They noted the difficulty of determining available forage per animal due to high annual and spatial variability in plant production, seasonal changes in forage quantity and quality, livestock species mix, and the use of supplemental feeds.

Paper explores the relationships between the following concepts under the conditions of Middle Eastern semi-arid ecosystems. Paper states that there are two apparent contradictions in the title of this paper. First, grazing by domestic livestock is often considered to be hostile to nature conservation, especially in semi-arid areas (the ongoing conflict between ranchers and environmentalists in western USA is just one contemporary example of this).

The present paper is based on a participatory survey carried out in order to establish baseline information on a little known livestock production system and its role in local ecology and economy.The study is based on research in El Kala National Park (North East Algeria).This paper draws attention to some of the problems that arise in understanding the cost and benefit flows in pastoralist systems.

Library ResourceJanuary, 1989Morocco, Northern Africa, Western Asia
In Morocco's Western High Atlas Mountains, Berber agropastoralists are oblivious to the ideological debate over land tenure occurring in the rangeland development community. Berber producers of sheep and goats use a continuum of tenure institutions, from private ownership, to communal control, to uncontrolled, open range. Far from being ideological opposites, these different types of land tenure are complementary tools.

This article discusses the enclosure of rangelands and registration of exclusive rights to grazing by individuals or groups of pastoralists. This trend has been increasing greatly over the last twenty years. This occurs because:it is encouraged by governments, planners and multi-lateral donor agencies in an attempt to 'rationalise'the use of rangelands.
