Abstract

Livestock production in sub-Saharan Africa (SSA) is not matching the annual 2.5 % growth of its population. Regional per capita meat and milk production corresponds, respectively, to about 13 and 8 % of developed countries indicators. Livestock performances in this region have decreased within the last 30 years. In fact, SSA, with a 12 % bovine extraction rate against a world average of 21 %, includes about 16 % of world cattle, only producing 6 and 2.6 % of global meat and milk, respectively. These low performances have economic and environmental consequences reflecting the necessity for upgrading livestock managing skills in the region. This effort includes various components such as sanitary prophylaxis, reproduction, nutrition, and in particular, substantial increase in livestock yield for human consumption. This will allow for an improved animal and pasture management and soil preservation, enhancing meat production and decreasing methane and nitrogen emissions from enteric fermentation and manure processing. These environmental gains due to increased livestock off-take rates can represent relevant credits in the global Environmental Carbon Market under the United Nations Framework Convention on Climate Change Kyoto protocol. These credits can be used for investments in livestock essential services and marketing facilities leading to improved productivity.
