可持续的畜牧业经济取决于生产和消费,在地方、国家和全球市场上有着不可分割的联系。在每一个规模上,技术创新和生产实践都需要对畜牧系统的市场和非市场属性的不断变化的需求作出反应。本次审查审议了最近和不断变化的需求方面的挑战,重点是与生产和消费产生的环境、饮食和健康影响有关的新出现的偏好。这表明,这些属性需要成为高生产力动物系统的任何定义的组成部分。这一讨论主要是使用新古典经济理论框架,该理论强调市场失灵以及消极和积极的外部效应或社会成本的作用。它探讨了我们对这些属性的需求的理解是如何演变的,在某些情况下导致市场分割,以及随着消费决策的变化对畜牧业生产的生存威胁,投资者寻求避免与温室气体排放和潜在的抗菌素耐药性相关的潜在责任,政府干预以控制其他不受欢迎的社会成本。讨论区分了高收入国家和低收入国家的市场需求,以及在一个超链接性更强的世界中,收入和消费轨迹如何可能不那么确定,在这个世界中,产品信息可能会加速对畜牧产品的偏好演变。审查承认新古典主义方法的局限性,提请注意增长和价值多元化的生物物理限制等更基本的概念,这表明价值(例如内在价值)超出了新古典主义的需求和价值框架。
A sustainable livestock economy depends on both production and consumption, inextricably linked in local, national and global markets. At each scale, technical innovation and production practices need to respond to evolving demand for both market and non-market attributes of livestock systems. This review considers recent and evolving demand-side challenges focussing on emerging preferences related to environmental, dietary and health impacts, arising from both production and consumption. It suggests that these attributes need to be integral to any definition of high-producing animal systems. This discussion is mostly framed using neoclassical economic theory, which highlights market failure and the role of negative and positive external effects or social costs. It examines how our understanding of the demand for these attributes is evolving, leading to market segmentation in some cases, and an existential threat to livestock production as consumption decisions change, investors seek to avoid potential liabilities related to greenhouse gas emissions and potentially antimicrobial resistance, and governments intervene to control other undesirable social costs. The discussion distinguishes between market imperatives in high- and lower-income countries, and how income and consumption trajectories may be less deterministic in a more hyperlinked world where product information may accelerate the evolution of preferences towards and away from livestock products. The review acknowledges the limits of a neoclassical approach, drawing attention to more fundamental concepts of biophysical limits to growth and value pluralism, which indicates values (e.g. intrinsic) that lie beyond the neoclassical framing of demand and value.
