An integrated biophysical and ecosystem approach as a base for ecosystem services analysis across regions

In an interconnected world, the ‘food system’ sustainability of any given region is increasingly dependent on ecosystem services originated from supporting regions in different parts of the world. However, commonly used research approaches, such as place based ecosystem service assessments and interregional biophysical accounting, have limited capacity to capture the complex interactions across regions. This research addresses this gap by integrating a global biophysical accounting of food crops with its related local ecosystem dis-services. It combines agricultural and ecosystem indicators to describe different classes of biophysical pressures and potential dis-services from growing 4 key agricultural staples exported to Israel from different agricultural areas around the world. Each class stands as a ‘functional region’ in which either a trade-off or a synergy exists between agricultural efficiency and environmental impact. The research finds that over half of Israel’s crops supply was produced in areas with high soil loss potential, and almost 15% of it originates from areas with high water scarcity. It implies that changes to Israel’s supply sources have the potential to reduce consumption related impacts on ecosystem services. The functional regions typology may be used as a global road map mediating interregional flows assessments with place-based ecosystem service assessments.

综合的生物物理和生态系统方法,作为跨区域生态系统服务分析的基础

在一个相互联系的世界中,任何给定区域的“粮食系统”可持续性越来越依赖于源自世界不同地区支持区域的生态系统服务。但是,常用的研究方法,例如基于地点的生态系统服务评估和区域间生物物理核算,在捕获跨区域复杂相互作用方面的能力有限。这项研究通过将全球粮食作物的生物物理核算与相关的当地生态系统服务整合在一起,解决了这一差距。它结合了农业和生态系统指标,描述了不同类别的生物物理压力和来自全球不同农业地区出口到以色列的4种主要农业主粮的潜在危害。每个类别都代表着一个“功能区”,在其中农业效率与环境影响之间存在着权衡或协同作用。研究发现,以色列一半以上的农作物供应是在土壤流失潜力较高的地区生产的,其中几乎有15%来自缺水率很高的地区。这意味着改变以色列的供应来源有可能减少与消费有关的对生态系统服务的影响。功能区域类型学可以用作全局路线图,将区域间流量评估与基于地点的生态系统服务评估进行中介。其中近15%来自缺水率高的地区。这意味着改变以色列的供应来源有可能减少与消费有关的对生态系统服务的影响。功能区域类型学可以用作全局路线图,将区域间流量评估与基于地点的生态系统服务评估进行中介。其中近15%来自缺水率高的地区。这意味着改变以色列的供应来源有可能减少与消费有关的对生态系统服务的影响。功能区域类型学可以用作全局路线图,将区域间流量评估与基于地点的生态系统服务评估进行中介。
