More than five billion metric tons of agricultural residues are produced annually worldwide. Despite having multiple uses and significant potential to augment crop and livestock production, a large share of crop residues is burned, especially in Asian countries. This unsustainable practice causes tremendous air pollution and health hazards while restricting soil nutrient recycling. In this review, we examine the economic rationale for unsustainable residue management. The sustainability of residue utilization is determined by several economic factors, such as local demand for and quantity of residue production, development and dissemination of technologies to absorb excess residue, and market and policy instruments to internalize the social costs of residue burning. The intervention strategy to ensure sustainable residue management depends on public awareness of the private and societal costs of open residue burning.

作物残茬管理经济学

全球每年产生超过 50 亿吨农业残留物。尽管农作物秸秆具有多种用途，并且在增加农作物和牲畜生产方面具有巨大潜力，但仍有很大一部分农作物秸秆被焚烧，特别是在亚洲国家。这种不可持续的做法造成了巨大的空气污染和健康危害，同时限制了土壤养分的循环利用。在本次综述中，我们研究了不可持续残留物管理的经济原理。残渣利用的可持续性取决于多种经济因素，例如当地对残渣生产的需求和数量、吸收多余残渣的技术的开发和推广，以及将残渣燃烧的社会成本内部化的市场和政策工具。确保可持续残留物管理的干预策略取决于公众对露天残留物燃烧的私人和社会成本的认识。
