CNH-L: Social-Ecological Dynamics of Recreational Fishery Landscapes

这一跨学科研究项目将探索淡水休闲渔业景观的动态，其中社会和生态过程以复杂的方式相互作用，以确定鱼类种群和依赖它们的人类种群的状况。该项目将加强对渔业系统动态以及对这些资源和其他类型的共用资源的管理的基本了解。它将为社会、生态和社会生态科学的理论发展做出贡献。该项目将对与设计原则有关的理论进行强有力的测试，这些原则允许成功的集体行动，以避免共用资源问题。它将对淡水和海洋渔业生态学的核心理论进行实证测试，并将探索新的经济模型，旨在研究空间复杂的开放获取系统中社会福利的消散。该项目将帮助决策者和公民更好地了解休闲渔业景观中的自然-人类动态，从而提高他们确定路径和克服成功管理渔业资源的障碍的能力。该项目还将为博士后研究人员、研究生和本科生提供宝贵的教育和培训机会。美国和世界其他地区的休闲渔业景观具有巨大的文化和经济价值，但它们很容易退化，在许多地区，它们正在遭受类似于困扰许多海洋渔业的崩溃。以前的研究表明，地方组织参与治理可能会改善共用资源系统的成果，但尚不清楚这种安排是否有效。研究人员将重点确定休闲渔业景观有效治理的途径和障碍，他们将研究这些系统，以检验和推广社会、生态和社会生态理论。研究人员将进行鱼类计数并进行大规模实验，以评估栖息地复杂性如何影响幼鱼死亡率，以及鱼类丰度与垂钓渔获量之间的关系。他们将采访垂钓者，并开发和测试经济模型，以了解垂钓者的偏好和信息来源如何决定整个地区的捕捞努力分配。调查人员将与当地组织进行面谈，并对其制度安排进行编目，以了解这些组织是如何就渔业质量投资做出决定的，他们将分析导致集体行动成功的组织特征。研究人员将结合阶段结构渔业模型和基于主体的社会模型，综合他们的工作，探索有效管理休闲渔业景观的途径和障碍。该项目得到了美国自然与人类耦合系统动力学(CNH)计划的支持。

This interdisciplinary research project will explore the dynamics of freshwater recreational fishery landscapes, where social and ecological processes interact in complex ways to determine the status of fish populations and the human populations that depend on them. The project will enhance basic understanding about the dynamics of fisheries systems and the governance of these and other kinds of common-pool resources. It will contribute to theoretical development in the social, ecological, and social-ecological sciences. The project will provide robust tests of theories related to the design principles that allow successful collective action to avoid common-pool resource problems. It will provide empirical tests of theories that are central to freshwater and marine fisheries ecology, and it will explore new economic models designed to examine the dissipation of social welfare in spatially complex, open-access systems. The project will help decision makers and citizens to better understand coupled natural-human dynamics in recreational fisheries landscapes, thereby improving their capabilities to identify pathways and overcome obstacles to successful governance of fishery resources. The project also will provide valuable education and training opportunities for post-doctoral researchers, graduate students, and undergraduate students.Recreational fishery landscapes across the United States and other parts of the world have tremendous cultural and economic value, but they are vulnerable to degradation, and in many regions, they are suffering collapses similar to the collapses that have plagued many marine fisheries. Previous research suggests that the involvement of local organizations in governance may improve outcomes in common-pool resource systems, but it is not clear whether this arrangement can be effective. The investigators will focus on identifying pathways and obstacles for effective governance of recreational fishery landscapes, and they will study these systems to test and extend social, ecological, and social-ecological theory. The investigators will conduct fish counts and engage in large-scale experiments to assess how habitat complexity influences juvenile fish mortality and the relationship between fish abundance and angler catch. They will interview anglers and will develop and test economic models to understand how angler preferences and information sources determine the allocation of fishing effort across the landscape. The investigators will conduct interviews with local organizations and will catalog their institutional arrangements to understand how the organizations make decisions about investments in fishery quality, and they will analyze the organizational characteristics that lead to successful collective action. The investigators will combine stage-structured fisheries models with agent-based social models to synthesize their work and explore pathways and obstacles to effective governance of recreational fishery landscapes.
