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 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.

Assesses the effect (balance or imbalance) of the present relationships between the natural resource base and human activities; examines the role of some potentially destabilising forces, i.e, international markets, government programmes and socio-economic stratification; and reviews government's role in terms of its contributions to prudent natural resource management and options for the promotion of sustainable rural development.

The animal science systems group at Texas A & M University (TAMU) has developed a computer based beef cattle production model for use in tropical countries. This model can be used to predict animal and herd productivity under a variety of management regions in diverse environments. Economic analyses can then be made, based on these predictions.

The project focuses on access and control of water/land, and the associated management and governance mechanisms. L4 seeks to provide the people and governments of the Limpopo Basin with:
1. A package of ways to better understand and organise access rights to water for multiple uses from farm level to the basin and regional level,
2. A package of ways to organise technologies for different physical and socio-economic contexts so as to improve the management and control of water for multiple uses from one or more water sources,
