河流三角洲地区连接着流域、土地、沿海地区、海洋和人类住区，对环境治理和可持续发展提出了特殊的挑战。以亚马逊河口三角洲地区（AD）为重点，我们反思了塑造三角洲地区社会生态动态的高度功能相互依赖性所带来的挑战。本文介绍了一个概念框架的初步设计，用于分析三角洲地区作为耦合的社会生态系统（SES）。该框架的第一部分用于根据问题和/或集体行动困境定义增量SES。可以用五个组成部分来定义三角洲社会经济系统：社会经济系统、治理系统、生态系统资源系统、地形水文系统和海洋气候系统。这些组件与六种类型的远程耦合条件结合使用：社会人口、经济、治理、生态、物质和气候水文。该框架的第二部分提出了分析三角洲地区集体行动问题的策略，从次三角洲/局部到三角洲再到流域层面。该框架旨在支持案例研究和比较分析。本文提供了该框架在 AD 中的示例性应用。首先，我们应用该框架将 AD 定义和表征为耦合的 SES。然后，我们利用该框架来诊断与城市增长以及城市和工业污染对小规模渔业资源的影响相关的集体行动问题的例子。我们认为，三角洲地区的功能相互依赖特征需要新的方法来理解、诊断和评估社会生态变化当前和未来的影响以及三角洲地区可持续发展困境的潜在解决方案。
At the nexus of watersheds, land, coastal areas, oceans, and human settlements, river delta regions pose specific challenges to environmental governance and sustainability. Using the Amazon Estuary-Delta region (AD) as our focus, we reflect on the challenges created by the high degree of functional interdependencies shaping social-ecological dynamics of delta regions. The article introduces the initial design of a conceptual framework to analyze delta regions as coupled social-ecological systems (SES). The first part of the framework is used to define a delta SES according to a problem and/or collective action dilemma. Five components can be used to define a delta SES: social-economic systems, governance systems, ecosystems-resource systems, topographic-hydrological systems, and oceanic-climate systems. These components are used in association with six types of telecoupling conditions: socio-demographic, economic, governance, ecological, material, and climatic-hydrological. The second part of the framework presents a strategy for the analysis of collective action problems in delta regions, from sub-delta/local to delta to basin levels. This framework is intended to support both case studies and comparative analysis. The article provides illustrative applications of the framework to the AD. First, we apply the framework to define and characterize the AD as coupled SES. We then utilize the framework to diagnose an example of collective action problem related to the impacts of urban growth, and urban and industrial pollution on small-scale fishing resources. We argue that the functional interdependencies characteristic of delta regions require new approaches to understand, diagnose, and evaluate the current and future impacts of social-ecological changes and potential solutions to the sustainability dilemmas of delta regions.
