EXPLORING THE RECYCLING OF MANURE FROM URBAN LIVESTOCK FARMS: A CASE STUDY IN ETHIOPIA
《农业科学与工程前沿(英文)》 2021年 第8卷 第1期
• Livestock manure was the main organic waste in urban and peri-urban areas.
• Manure production will increase by a factor of 3–10 between 2015–2050.
• Only 13%–38% of excreted N by livestock will be recycled in croplands.
• Intensification of urban livestock production greatly increased N surpluses.
• Reducing population growth and increasing livestock productivity needed.
Urban population growth is driving the expansion of urban and peri-urban agriculture (UPA) in developing countries. UPA is providing nutritious food to residents but the manures produced by UPA livestock farms and other wastes are not properly recycled. This paper explores the effects of four scenarios: (1) a reference scenario (business as usual), (2) increased urbanization, (3) UPA intensification, and (4) improved technology, on food-protein self-sufficiency, manure nitrogen (N) recycling and balances for four different zones in a small city (Jimma) in Ethiopia during the period 2015-2050. An N mass flow model with data from farm surveys, field experiments and literature was used. A field experiment was conducted and N use efficiency and N fertilizer replacement values differed among the five types of composts derived from urban livestock manures and kitchen wastes. The N use efficiency and N fertilizer replacement values were used in the N mass flow model.
Livestock manures were the main organic wastes in urban areas, although only 20 to 40% of animal-sourced food consumed was produced in UPA, and only 14 to 19% of protein intake by residents was animal-based. Scenarios indicate that manure production in UPA will increase 3 to 10 times between 2015 and 2050, depending on urbanization and UPA intensification. Only 13 to 38% of manure N will be recycled in croplands. Farm-gate N balances of UPA livestock farms will increase to>1 t·ha−1 in 2050. Doubling livestock productivity and feed protein conversion to animal-sourced food will roughly halve manure N production.
Costs of waste recycling were high and indicate the need for government incentives. Results of these senarios are wake-up calls for all stakeholders and indicate alternative pathways.

矿产资源的自然属性、经济属性和社会属性,决定了矿产资源安全涉及众多资源类型、宏大空间分布、超长产业链条、巨大产业规模、跨越时空配置、复杂因素影响、层次纷繁多样。矿产资源安全规模之大、层次之多、影响因素之复杂难以穷尽,是一个复杂巨系统。使矿产资源安全巨系统高效运转以服务经济社会发展,是一项复杂性科学难题。本文引入系统科学的研究思路,提出了矿产资源安全巨系统概念,刻画了矿产资源安全巨系统的结构和组成,揭示了自然资源、经济、社会等因素对矿产资源安全巨系统的驱动机理,形成了矿产资源安全巨系统理论。在此基础上,建立了涵盖以系统思维研究构建矿产资源安全保障的理论知识模型、构建基于大数据平台的仿真实验系统、积极推动政府决策与反馈三大环节的矿产资源安全系统工程学研究新方向,提出了建立矿产资源安全的总体设计部战略思想。研究成果已应用于国家资源安全保障工作实践,有效支撑了国家矿产资源安全保障工作。
