    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.

    The objective of this study was to determine the practicality of using linear body measurement traits to predict live weight of goats and sheep under communal grazing in three districts of Botswana, namely Central, Kweneng, and Kgalagadi. Pairwise (Pearson) correlations were estimated using bodyweight (BW) and morphological trait measurements, namely heart girth (HG), shoulder height (SH), and body condition score (BCS) for a sample of 1447 goats and 588 sheep. These ranged from 0.19 to 0.94 for goats and 0.44 to 0.94 for sheep, and were statistically significant.

    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 discusses the zoning of 'Communual Areas' on tribal grazing land in Botswana, in which communities retain collective land rights.From the experience gained during six years of attempting to establish and operate communal grazing cells a number of conclusions can be drawn in relation to co-operative action and development project approaches and in the communal areas of Botswanahe communal grazing cell scheme was badly designed.

    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.
