| Abstract: | As part of a natural resource accounting project undertaken in Namibia, livestock accounts have been drawn up and are being used to analyse the relationship between numbers of livestock, rainfall, land degradation, and economic and policy variables. Part of the analysis concerns an investigation into trends in cattle numbers, changes in cattle biomass and the productivity of livestock in commercial areas. Cattle numbers increased from 1914 until 1960, then declined steadily to half that number. This decline was at least partly due to deliberate actions by farmers to improve herd productivity and production efficiency. Although beef production did not decline over this period, productivity is still lower than potential industry standards. Range degradation (bush encroachment) may have contributed to this curtailment. This investigation has implications for an understanding of long‐term carrying capacity, land degradation and rangeland management, and for agricultural development policies in Namibia and similar regions in southern Africa. |
