Ecosystem-based management (EBM) addresses the fundamental need to account for cumulative impacts of human activities with the aim of sustainably delivering ecosystem services. The Saronikos Gulf, a large embayment of the Aegean Sea, provides a wide range of ecosystem services that are impacted by multiple human activities, deriving from the metropolitan area of Athens (situated at the northeast part of the Gulf). The anthropogenic impacts affect the status of several marine ecosystem components, e.g., seagrass meadows. Cymodocea nodosa meadows are only present at the most confined western part of the Gulf, whereas Posidonia oceanica meadows are mainly distributed in the inner and outer part of the Gulf. The aim of this study is to assess the cumulative impacts from multiple human activities on the seagrass meadows in the Gulf. The main results indicated that most impacted meadows are P. oceanica in the inner part of the Gulf, adjacent to the most urbanized coastal areas, and near port infrastructures. Land-based pollution, as well as physical damage and loss seem to be the main pressures exerted on the meadows. Understanding cumulative impacts is crucial for informing policy decisions under an EBM approach.
基于生态系统的管理（EBM）旨在考虑人类活动的累积影响，以可持续地提供生态系统服务，从而满足这一基本需求。萨罗尼克湾（Saronikos Gulf）是爱琴海的一个大型海湾，提供了多种生态系统服务，这些服务受到来自雅典大都市区（位于海湾东北部）的多种人类活动的影响。人为影响影响了多个海洋生态系统组成部分的状况，例如海草草甸。Cymodocea nodosa 草甸仅存在于海湾最狭窄的西部，而波西多尼亚海草主要分布在海湾的内部和外部。本研究旨在评估多种人类活动对海湾海草草甸的累积影响。主要结果表明，受影响最严重的草甸是海湾内部靠近城市化程度最高的沿海地区和港口基础设施的 P. oceanica 草甸。陆基污染以及物理破坏和损失似乎是对草甸施加的主要压力。了解累积影响对于在基于生态系统的管理方法下为政策决策提供信息至关重要。
