Scenario and policy assessments in socioeconomic and environmental studies face significant challenges in socio-ecological systems (SES). There are a limited number of studies that have looked at the impact of different scenarios within integrated approaches, and many have used a static approach with a single driver of change. The present work analyzes the SES dynamics for a strategic basin in the Colombian Andes when implementing and analyzing scenarios and policies related to land cover and land use change using a system dynamics simulation model. The model includes natural, ecosystem services, sociocultural, and economic components. Scenarios and policy options are analyzed both individually and jointly to identify synergies or trade-off effects between the different SES components. The results showed the different trajectories of the socio-ecological system according to the cases studied, and its impact on different variables in the analyzed components. Some counterintuitive effects were also identified, such as the importance of intrinsic motivations in decision-making processes, and determinants in land management and policy design.
在社会生态系统(SES)中,社会经济和环境研究中的情景和政策评估面临重大挑战。只有少数研究关注了综合方法中不同情景的影响,而且许多研究都采用了单一驱动因素的静态方法。本工作使用系统动力学模拟模型,分析了哥伦比亚安第斯山脉一个战略流域的 SES 动态,该模型包含自然、生态系统服务、社会文化和经济等组成部分。对情景和政策选项进行了单独和联合分析,以识别不同 SES 组成部分之间的协同作用或权衡效应。结果表明,根据所研究的案例,社会生态系统呈现出不同的轨迹,以及对分析组成部分中不同变量的影响。还发现了一些违反直觉的效应,例如内在动机在决策过程中的重要性,以及土地管理和政策设计中的决定因素。
