偏远地区的土地使用变化越来越受到国际农业贸易的影响，但大多数影响和反馈仍然未知。远距离耦合框架是一种分析工具，用于研究远距离的社会经济和环境相互作用，可用于概念化农业贸易对土地使用变化的影响，以及进出口国边界之间和土地系统时空尺度之间的反馈。我们应用该框架来设计一个基于代理的模型（TeleABM），代表土地利用的变化，在电信耦合系统，调查当地的土地利用变化是如何受到流量的影响。巴西-中国的远距离耦合大豆系统被用作示范。通过研究问题的例子，我们探索了这个模型在评估农场收入、肥料使用、森林砍伐和农业集约化方面的可能应用，作为量化遥远地方之间社会生态影响的工具，并全面告知跨系统边界的可持续土地实践。
Land-use changes across distant places are increasingly affected by international agricultural trade, but most of the impacts and feedback remain unknown. The telecoupling framework - an analytical tool for examining socioeconomic and environmental interactions over distances - can be used to conceptualize the impacts of agricultural trade on land-use change and feedbacks across borders of importing and exporting countries and across spatio-temporal scales of land systems. We apply the framework to design an agent-based model (TeleABM) that represents land-use changes in telecoupled systems to investigate how local land-use changes are affected by flows. The Brazil-China telecoupled soybean system is used as a demonstration. With examples of research questions, we explore the possible applications of this model for assessing farm-level income, fertilizer usage, deforestation, and agricultural intensification, as a tool to quantify socio-ecological impacts between distant places and holistically inform sustainable land-practices across system boundaries.
