Urban livestock keeping is increasing in many sub-Saharan African cities, but detailed contextual information on its extent, challenges, and potential is limited. A cross-sectional household study was done in 2010 in Bamako, Mali. Thirty-two of 67 quarters were randomly selected with selection probability proportional to the size of the human population of the communes. Questionnaire interviews were done with a head of household in 1141 households, comprising 19,816 people in total. Sheep were kept by 16% (95% CI 14-18), while 21% (95% CI 17-24) kept poultry. The sheep to human ratio was 4:100, with an extrapolated city-wide population of 67,636 sheep (95% CI 61,018-75,595). The poultry to human ratio was 11:100, with an extrapolated city-wide population of 191,802 chickens (95% CI 176,212-208,772). For urban livestock holders, household-level enterprise gross margins were calculated for sheep production at USD 103 and poultry production at USD 50 annually. The annual gross margin was estimated at USD 35 per sheep and USD 17 per chicken. Based on these figures, the city-wide urban livestock total gross margin for Bamako in 2010 was estimated at USD 5.6 million. Detailed population data help clarify the urban livestock animal human interface in diverse contexts and highlight the important contributions that urban small-holder production adds to food security and resilience. The potential for urban livestock production informs decision-makers in developing adapted, sustainable policies in resource-constrained environments.
在撒哈拉以南非洲的许多城市，城市家畜饲养量正在增加，但关于其规模、挑战和潜力的详细背景信息有限。2010年在马里巴马科进行了一项横断面家庭研究。从67个街区中随机选取了32个，选取概率与各社区人口规模成正比。对1141户家庭的户主进行了问卷调查，这些家庭共有19816人。16%（95%置信区间14 - 18）的家庭饲养绵羊，21%（95%置信区间17 - 24）的家庭饲养家禽。绵羊与人的比例为4:100，据此推算全市绵羊数量为67636只（95%置信区间61018 - 75595）。家禽与人的比例为11:100，据此推算全市鸡的数量为191802只（95%置信区间176212 - 208772）。对于城市家畜养殖户，家庭层面企业的毛利润计算得出，绵羊养殖每年为103美元，家禽养殖每年为50美元。每只绵羊的年毛利润估计为35美元，每只鸡为17美元。基于这些数据，2010年巴马科全市城市家畜总毛利润估计为560万美元。详细的人口数据有助于在不同背景下阐明城市家畜与人的关系，并突出城市小农户生产对粮食安全和恢复力的重要贡献。城市家畜生产的潜力为决策者在资源受限环境中制定适应性强、可持续的政策提供依据。
