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.

作物残留物管理经济学


全球每年产生超过 50 亿公吨的农业废弃物。尽管具有多种用途和增加作物和畜牧业生产的巨大潜力，但很大一部分作物残留物被焚烧，尤其是在亚洲国家。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。在这篇综述中，我们研究了不可持续的残留物管理的经济原理。残渣利用的可持续性由几个经济因素决定，例如当地对残渣生产的需求和数量、吸收过剩残渣的技术的开发和传播，以及将残渣焚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焚烧的私人和社会成本的认识。
