    Savannas are extremely important socio-economic landscapes, with pastoralist societies relying on these ecosystems to sustain their livelihoods and economy. Globally, there is an increase of woody vegetation in these ecosystems, degrading the potential of these multi-functional landscapes to sustain societies and wildlife. Several mechanisms have been invoked to explain the processes responsible for woody vegetation composition; however, these are often investigated separately at scales not best suited to land-managers, thereby impeding the evaluation of their relative importance.

    A useful debate is developing over carrying capacity and the degradation of communal rangelands in sub-Saharan Africa. With a few lonely exceptions, scientists and policy-makers have in the past claimed that degradation is universal and livestock productivity lowered because of overstocking on communal range. This position has been mainly dogmatic. More recent research has not supported dogmatists; hence the debate, which impinges on livestock development policy in Botswana.A new livestock development policy is being promoted by the Government of Botswana (Ministry of Agriculture 1991).

    This article suggests that communual rangeland management policies in Botswana and Zimbabwe are based on incorrect technical assumptions about the stability of semiarid rangelands, the nature of rangeland degradation, and the benefits of destocking. Consequently, inappropriate policies, stressing the need to destock and stabilise the rangelands, are pursued.Acknowledgement of the great instability but intrinsic resilience of rangeland would encourage the Governments to more favourable regard the opportunistic stocking strategies of the agro-pastoralists of the Communual Areas.

    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.

    The objective of this study was to determine the impact of livestock grazing management systems on soil and vegetation dynamics under different environmental conditions of Botswana. Soil and vegetation were randomly sampled along transects located in three ranches and adjacent communal grazing land in 2009 and 2010. Our results showed that grazing management systems did not consistently affect soil texture, organic carbon, pH and bulk density.

    The aim of this paper is to discuss the role of existing policies, programmes and legislation in promoting sustainable land management and livelihoods in mid‐central Botswana. The paper is based on data from the survey of relevant literature, analysis of policy and legal documents, field observations and a series of stakeholder workshops held in the villages of Mopipi, Mokobaxane and Rakops in Boteti Sub‐District between 2008 and 2009.

    Les terres arides couvrent près de la moitié de la surface terrestre et abritent un tiers de la population mondiale. Elles sont confrontées à des défis hors du commun, notamment ceux posés par la désertification, la perte de biodiversité, la pauvreté, l’insécurité alimentaire et les changements climatiques. Quelque 20 pour cent des terres arides de la planète sont dégradées, et les personnes qui vivent sur ces terres sont souvent piégées dans un cercle vicieux de pauvreté, pratiques destructrices et détérioration de l’environnement.
