A System Dynamics model of the rural socio-environmental system of the SW Messinia and Gialova lagoon

This System Dynamics model describes interactions between different sectors of the rural social ecological system and the land sea interactions of Southwest Messinia and Gialova coastal lagoon, in Greece. The model allows simulation of the current situation as well as scenario projections and possible policy solutions identified through a participatory process with stakeholders from all involved sectors. Model output is presented as impacts on multiple Key Performance Indicators of sustainability including environmental, social and economic aspects. Through these simulations, the model aims to support integrated planning and better informed decision making.<br> The structure of the System Dynamics model was co-developed through a series of consecutive workshops with representatives from all sectors, which fostered shared learning and validation throughout the development process Throughout the participatory process which also included, expert interviews and questionnaires between 2018 and 2022, representatives from all sectors identified the main interactions between sectors and developed a vision for the area that could help stir the SW Messinia into a sustainable and resilient pathway. The Mental maps of the interactions between sectors that were developed during this participatory process formed the starting point for the System Dynamics model and can be found here.本系统动力学（System Dynamics）模型刻画了希腊西南梅西尼亚与吉亚洛瓦沿海泻湖区域乡村社会生态系统各部门间的相互作用，以及该区域的陆海交互关系。该模型可模拟当前现状，开展情景预测，并对通过与各涉利部门利益相关方开展的参与式流程所确定的可行政策方案进行推演。模型输出以对可持续性多维度关键绩效指标（Key Performance Indicators）的影响形式呈现，涵盖环境、社会与经济三大维度。通过此类模拟，本模型旨在助力一体化规划与基于充分信息的科学化决策。 本系统动力学模型的架构通过与各部门代表开展的一系列连续工作坊协同开发而成，在整个开发过程中促进了共享式学习与成果验证。在2018至2022年间开展的、包含专家访谈与问卷调查的参与式流程中，各部门代表明确了部门间的核心相互作用关系，并为该区域制定了可持续且具备韧性的发展愿景，助力西南梅西尼亚走上可持续韧性发展路径。本次参与式流程中形成的部门间相互作用心智地图（Mental maps），为本系统动力学模型的构建提供了初始基础，相关内容可在此处查阅。
