Livestock are important assets in Africa, helping improve the nutritional status of their owners, and contributing to economic growth. Can these roles continue and can livestock production systems be further developed so that they will be sustainable? A key feature of livestock in Africa is that they fulfill multiple roles, ranging from draught power, to providing manure, milk, and meat. Constraints to increasing productivity include both physical and institutional. In the former category, constraints to adopting draught power include insufficient numbers (...) at the individual household level. Lack of adequate pasture is probably the most important constraint. Diseases are also notable constraints to improving productivity, particularly those categorized as Group I (highly contagious — e.g., rinderpest) or Group II (vector-borne parasitic and viral—e.g., trypanosomiasis). Institutional constraints include lack of research and market distortions. To improve productivity, at the macroeconomic level, governments must continue or start policies aimed at liberalizing markets and revaluing exchange rates. Also, research institutions need an increase in funding for periods of ten or more years. Research and other livestock institutions may be able to leverage limited resources by forming more collaborative relationships at the regional level. Research priorities include breeding on specific aspects, such as increased milk production. However, it must be realized that breeding programs have an inherent problem in disseminating improved breeds in a rapid and equitable manner. Quality of pasture may be improved by further research on more accurately calculating stocking rates and on developing mechanisms to control numbers on pastures (e.g., community controlled grazing schemes). Other research priorities include new technologies to improve animal health, funding of micro-enterprises to add value to livestock products, and market information systems for small-scale farmers. Schemes to increase livestock production in Africa will only occur if innovations closely match the local sets of circumstances. Given the multiple roles of livestock, research into innovations that local communities will readily adopt must take a systems approach. (shrink)
