Where's the beef? A systems model for taming a wicked environmental problem

对牛肉的需求正在急剧增加，尤其是在亚洲。该项目旨在建立牛肉生产对当地环境影响的系统模型，并结合全球牛肉贸易模型来分析生产和政策情景。牛肉是生态足迹最大的食品，其产量的增加将对土地和水资源、生物多样性和气候产生全球性的重大影响。这些影响的程度取决于养牛生产的地点和方式。这项研究的成果包括一个框架，用于预测国内养牛生产政策的区域和全球生态影响，从而做出考虑并有利于环境和社会经济价值的明智决策。

Demand for beef is increasing dramatically, particularly in Asia. This project aims to build systems models of local environmental impacts of beef production coupled with models of global beef trade to analyse production and policy scenarios. Beef is the food commodity with the largest ecological footprint, and increased production will have globally significant impacts on land and water resources, biodiversity, and climate. The scale of these impacts depends on where and how cattle production occurs. Outcomes of this research include a framework for projecting regional and global ecological impacts of domestic cattle production policies, allowing informed decisions that consider and benefit environmental and socio-economic values.
