US - Combining global economics, geography, ecology and environmental sciences is essential to understanding how changes in trade and natural systems in one part of the world affect those in another, a review concludes.
Tom Hertel, professor of agricultural economics, collaborated with an interdisciplinary team of experts led by Jianguo Liu of Michigan State University to determine how systems integration - using holistic frameworks to model many components of both human and natural systems - could shed insights on how activities in one part of the world can have significant impacts on distant regions. Hertel said these multivariable models could help policymakers make better-informed decisions, further scientists' understanding of the links between trade and the global environment, and aid natural resource managers in making management choices that will sustain resources such as clean water and air for future generations.
美国——了解贸易和自然系统是如何变化，结合全球经济、地理、生态学和环境科学是必需的，一个世界的一部分可能影响另一个世界的另一部分，某综述总结。
农业经济学教授汤姆· 赫特尔(Tom Hertel)与一个由密歇根州立大学刘建国(Jianguo Liu)领导的跨学科的专家团队来确定系统的集成，使用整体框架构建许多人类和自然系统的组件——可以深入了解在一个世界的一部分如何可以在遥远的地区产生重大影响。赫特尔说这些多变量模型可以帮助决策者作出更明智的决定，使科学家们进一步了解贸易和全球环境之间的联系，帮助自然资源管理者为后代保持资源，比如干净的水和空气，做出管理方面的决定。
