Ecosystem services and the biodiversity that supports them directly provision food and livelihoods to millions around the world within environments increasingly facing multifaceted changes. Yet the perspectives of resource users on the value of those resources and the challenges they face amid social-ecological change are still too often poorly understood. In this study, we use Photovoice methodology and a social-ecological systems perspective to understand the value of access to fish resources and the impacts of changing access for small-scale fishing communities in Cambodia. Contrasting the perspectives of households in different ecological settings, including adjacent to the Tonle Sap Lake and within its floodplain, revealed stark differences in the experiences of regulation enforcement and fisheries management for communities that had viable alternatives to fishing compared to those without options beyond fishing. The study addresses the need to understand both the lived experiences of those on the frontlines of environmental changes, and to disentangle the heterogeneous experiences across and within communities to improve resource management and community support in complex, changing social-ecological systems.

在日益面临多方面变化的环境中，生态系统服务和支持它们的生物多样性直接为世界各地数百万人提供粮食和生计。然而，人们对资源使用者对这些资源的价值以及他们在社会生态变化中面临的挑战的看法仍然知之甚少。在这项研究中，我们使用 Photovoice 方法和社会生态系统视角来了解获取鱼类资源的价值以及改变柬埔寨小规模渔业社区获取鱼类资源的影响。对比不同生态环境中的家庭的观点，包括洞里萨湖附近及其洪泛区内的家庭的观点，发现有可行的捕鱼替代方案的社区与除了捕鱼之外没有其他选择的社区相比，在法规执行和渔业管理方面的经验存在明显差异。该研究解决了了解环境变化前沿人们的生活经历的需要，并理清社区之间和社区内部的异质经历，以改善复杂、不断变化的社会生态系统中的资源管理和社区支持。
