CNH2-L: Integrating Cross-scale Socio-Ecological Feedbacks in Freshwater Fisheries

淡水渔业为数百万人提供食物、收入和娱乐。这些系统的常规管理通常依赖于基于鱼类种群评估的管理规则的执行。很少考虑机构执行管理规则的能力或影响渔民遵守这些规则的动机的社会因素。因此，淡水渔业往往管理不善和过度捕捞。该项目与一个基于社区的淡水鱼管理系统合作，将综合鱼类生态学、种群动态、机构分析和社会心理学，以了解影响淡水渔业可持续性的社会和生态因素。研究结果将为以社区为基础的鱼类资源管理的综合动态的政策提供信息。除了研究生教育和同行评议的研究发表外，我们还将在我们的案例研究的基础上，开发一个针对高年级本科生的开放访问的、基于网络的渔业自然和人类系统耦合培训计划。该计划将使用书面、视频和基于项目的材料，以满足高等教育对开发和共享人与自然耦合系统中的教材的日益增长的需求。该项目将研究泛滥平原生态系统、淡水鱼的运动及其对湖泊的利用之间的相互作用，在生态方面，以及在社会方面，文化、社区、机构和渔民规则遵守之间的相互作用。该小组将使用一种综合建模方法，在三个分析尺度上纳入社会和生态因素，以对渔业综合动态提出新颖和一般性的见解。为此，他们将收集广泛的社会生态数据，并利用与渔民和管理者的知识联合生产来解决四个主要研究问题：生境和连通性如何影响湖泊之间的鱼类移动，以确定鱼湖利用的驱动因素，从而解释其在整个生态系统中的丰富程度；考虑到社区文化、领导层和机构安排，渔民对鱼类丰富度和他们从捕捞中获得的收入的看法如何影响他们对机构规则的遵守；规则遵守如何受到区域因素、市场和政府规则的影响；最后，由于可持续发展的新特性来自社会和生态因素的相互作用，生态系统生境和连通性以及渔民遵守规则如何影响鱼类种群的动态。该方法将通过对淡水渔业和其他常见池塘资源(如海洋渔业或野生动物)的自然和人类系统耦合研究的理论、方法和应用的开创性贡献，推动知识前沿。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Freshwater fisheries provide food, income, and recreation to millions of people. Conventional management of these systems typically relies on the implementation of management rules based on assessments of fish populations. Little consideration is given to the capacity of institutions to enforce management rules or the social factors that affect the motivations of fishers to comply with them. Consequently, freshwater fisheries are often poorly managed and overfished. Working with a community-based management system for freshwater fish, this project will integrate fish ecology, population dynamics, institutional analysis, and social psychology to understand the social and ecological factors affecting the sustainability of freshwater fisheries. Research results will inform policy on the integrated dynamics of community-based management of fish resources. In addition to education of graduate students and peer-reviewed publication of the research, we will build on our case study to develop an open-access, web-based training program on fisheries as coupled natural and human systems aimed at senior-level undergraduate students. This program will use written, video, and project-based materials to contribute to fill the growing demand in higher education for development and sharing of teaching materials in coupled human and natural systems. This project will study interactions between floodplain ecosystems, movement of freshwater fish, and their use of lakes on the ecological side, and culture, community, institutions, and fisher rule compliance on the social side. The team will use an integrated modeling approach that incorporates social and ecological components at three scales of analysis to produce novel and general insights on the integrated dynamics of fisheries. To do this, they will collect extensive socio-ecological data and use knowledge co-production with fishers and managers to address four overarching research questions: how habitat and connectivity affect fish movement among lakes to identify drivers of fish lake use, and thereby explain their abundance across the ecosystem; how fishers’ perceptions of fish abundance, and income they derive from fishing, affect their compliance with institutional rules, given community culture, leadership, and institutional arrangements; how rule compliance is affected by regional factors, markets, and government rules; and finally, because the emergent property of sustainability arises from the interplay of social and ecological factors, how ecosystem habitat and connectivity and fishers’ rule compliance affect the dynamics of fish populations. The approach will push knowledge frontiers by pioneering contributions to the theory, methods, and applications of coupled natural and human systems research to freshwater fisheries and other common pool resources such as marine fisheries or wildlife.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
