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 paper employs an historical analysis to consider some of the consequences of conflicting resource use and political friction on resource exploitation within and outside Turkana District during this century. Given this historical context, development alternatives tested to ameliorate food insecurity are reviewed.The article proposes that the stage for political conflicts, environmental degradation and food insecurity within the region was set decades ago.

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. The inherent problems with each approach are discussed in the light of a recent, wider debate, questioning the validity of CC as a range management tool.Methodological approaches for determination of CC, with inherent problems, are discussed.

This paper is based on a series of studies conducted by the author on the settlement problems, work roles and educational experiments among nomadic Fulani in Plateau, Bauchi and Kaduna States, Nigeria, from 1982 to 1984.The first part of this paper describes the land tenure system in northern Nigeria and the way in which it affects pastoral nomads and plans for their settlement. The second part discusses the Nigerian Government;s intention to educate nomads and gives the example of special schemes which have attempted to do this.

This article discusses the history of land reform in Namibia. The article indicates that at the time of writing (September 1991), it is still too early to comment on the implementation of land reform in Namibia, as it has not yet begun in earnest. Land policy has yet to be detailed and ratified, the institutions for implementing land reform and settlement programmes have to be appointed and in some cases created de novo, and large sums of money have to be found.

Attempts at settling or sedentarizing nomadic herders in semi-arid and arid regions have been largely unsuccessful, partly on account of the difficulty of restricting the movements of domestic livestock in areas where low and irregular rainfall lead to scant and unreliable sources of water and grazing. But for the herders in sub-humid regions, where both water and vegetation resources are much more reliable and substantial, there appear to be different possibilities.

This paper focuses on extracts from a recent comparative analysis of livestock and land use surveys across a range of agro-climatic conditions in sub-Saharan Africa, based on information from systematic low level aerial reconnaissance and complementary ground studies in Mali, Niger, Nigeria, Sudan and Tchad, between 1980 and 1993.

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.

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.
