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.

This article investigates the encroachment on pastoralist grazing land in Sudan (as a result of the mechanised farming in the Sudan).

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.

This article discusses what is the best means of managing the commons. The article stresses that these are critical questions in the current wave of decentralisation and tenure reform taking place in many Sahelian states.

Over ten million people have been displaced from protected areas by conservation projects. Forced displacement in developing countries is a major obstacle to reducing poverty. It should no longer be considered a mainstream strategy for conservation and only applied in extreme cases following international standards.

Land policies in Africa have often overlooked the interests of certain social groups. In some areas, traditional access and ownership rights for women, migrants and pastoralists have been ignored or reduced. The rise of HIV/AIDS in the region has created new social groups who are vulnerable to discrimination by land policies. As new policies are formed in the region, it is important to consider why these groups have been excluded. This will help to ensure that future policies represent these groups more fairly.

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).
Library Resourcejanvier, 2001Italie, Europe
This article discusses the transhumant pastoralists of the Abruzzo highlands of central Italy. The article indicates that this system of production depended, and still depends, on the availability of communal grazing areas where access is open to all local residents and management is joint. The article discusses the relationship between herders, common property regimes and the State.The article concludes that:as a pastoral system increases in complexity, from being a self contained CPR to an outward-looking one, with moveable assets and flocks, transaction costs increase.
