Nairobi is a large rapidly-growing city whose demand for beef, mutton and goat products is expected to double by 2030. The study aimed to map the Nairobi beef, sheep and goat systems structure and flows to identify deficiencies and vulnerabilities to shocks. Cross-sectional data were collected through focus group discussions and interviews with people operating in Nairobi ruminant livestock and meat markets and in the large processing companies. Qualitative and quantitative data were obtained about the type of people, animals, products and value adding activities in the chains, and their structural, spatial and temporal interactions. Mapping analysis was done in three different dimensions: people and product profiling (interactions of people and products), geographical (routes of animals and products) and temporal mapping (seasonal fluctuations). The results obtained were used to identify structural deficiencies and vulnerability factors in the system. Results for the beef food system showed that 44–55% of the city's beef supply flows through the ‘local terminal markets’, but that 54–64% of total supply is controlled by one ‘meat market’. Numerous informal chains were identified, with independent livestock and meat traders playing a pivotal role in the functionality of these systems, and where most activities are conducted with inefficient quality control and under scarce and inadequate infrastructure and organisation, generating wastage and potential food safety risks in low quality meat products. Geographical and temporal analysis showed the critical areas influencing the different markets, with larger markets increasing their market share in the low season. Large processing companies, partly integrated, operate with high quality infrastructures, but with up to 60% of their beef supply depending on similar routes as the informal markets. Only these companies were involved in value addition activities, reaching high-end markets, but also dominating the distribution of popular products, such as beef sausages, to middle and low-end market. For the small ruminant food system, 73% of the low season supply flows through a single large informal market, Kiamaiko, located in an urban informal settlement. No grading is done for these animals or the meat produced. Large companies were reported to export up to 90% of their products. Lack of traceability and control of animal production was a common feature in all chains. The mapping presented provides a framework for policy makers and institutions to understand and design improvement plans for the Nairobi ruminant food system. The structural deficiencies and vulnerabilities identified here indicate the areas of intervention needed.

内罗毕牛肉、绵羊和山羊食品系统图——政策制定和结构脆弱性和缺陷识别框架

内罗毕是一个快速发展的大型城市，其对牛肉、羊肉和山羊产品的需求预计到 2030 年将翻一番。该研究旨在绘制内罗毕牛肉、绵羊和山羊系统结构和流向图，以确定缺陷和易受冲击的脆弱性。横断面数据是通过焦点小组讨论和采访在内罗毕反刍牲畜和肉类市场以及大型加工公司的人员收集的。获得了有关链条中人、动物、产品和增值活动类型及其结构、空间和时间相互作用的定性和定量数据。地图分析在三个不同的维度进行：人和产品分析（人和产品的相互作用）、地理（动物和产品的路线）和时间映射（季节性波动）。获得的结果用于识别系统中的结构缺陷和脆弱性因素。牛肉食品系统的结果表明，该市 44-55% 的牛肉供应流经“当地终端市场”，但总供应量的 54-64% 由一个“肉类市场”控制。确定了许多非正式链，独立的牲畜和肉类贸易商在这些系统的功能中发挥着关键作用，并且大多数活动在质量控制效率低下以及基础设施和组织稀缺和不足的情况下进行，造成浪费和潜在的食品安全风险低质量的肉制品。地理和时间分析显示了影响不同市场的关键区域，较大的市场在淡季增加了市场份额。部分整合的大型加工公司拥有高质量的基础设施，但高达 60% 的牛肉供应依赖于与非正规市场类似的路线。只有这些公司参与了增值活动，进入了高端市场，但也主导了牛肉香肠等热门产品向中低端市场的分销。对于小型反刍动物食品系统，淡季供应的 73% 流经位于城市非正规住区的一个大型非正规市场 Kiamaiko。没有对这些动物或生产的肉进行分级。据报道，大公司高达 90% 的产品出口。缺乏对动物生产的可追溯性和控制是所有链条的共同特征。所呈现的地图为决策者和机构提供了一个框架，以了解和设计内罗毕反刍动物食品系统的改进计划。此处确定的结构性缺陷和脆弱性表明需要干预的领域。
