Collaborative Research: Resilience, Experimentation, and Collapse in Small-Scale Fisheries

这项研究审查了小规模沿海渔业和这些渔业系统对全球环境变化的适应能力，包括海平面变化、土地使用的改变和鱼类种群密度的波动。该项目通过研究过去两千年来沿海红树林湿地捕鱼行为和产量的决定因素，提供了对渔业恢复力的纵向见解。该研究利用不同的考古方法来考虑古代渔业生产力急剧下降的多种假设。更广泛地说，该项目揭示了生态变量，政治因素以及人类人口的文化和人口统计之间潜在的复杂和动态关系。考古学方法得到了现代捕鱼行为的观察的补充，这为过去生存行为的长期弹性提供了全面的见解。多名学生为研究做出了贡献，该项目的中心目标是开发一个合作博物馆展览，将研究结果置于背景中。该项目还举办了一个讲习班，以促进渔业的可持续管理，从人类生态学的角度，研究探讨了红树林渔业生产力的波动作为多个相关变量的函数，包括泻湖生态结构的内在动态变化，当地社区的政治组织，以及相邻土地的农业活动的交替。考古发掘得到沉积物岩心的补充，为研究渔业生产力提供了各种证据。放射性碳样本确定了该遗址的年代，甲壳类动物和花粉的遗骸以及其他植物遗骸有助于描述随着时间的推移而发生的生态变化。动物考古学对贝冢的分析提供了对不同鱼类随着时间的推移而变化的收获的见解。陶瓷和石器工具的额外分析被用来评估社会和政治的变化和农业生存的动态模式的变化。总的来说，这些数据有助于深入了解小规模渔业生产力变化的原因和后果。除了对考古学理论的贡献外，这项研究的结果还为当代渔业的管理策略提供了信息。该项目还有助于不同的早期职业学者的培训和教育。该奖项反映了NSF的法定使命，并被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。

This study examines the small-scale coastal fisheries and the resilience of these fishing systems to global environmental changes, including changes in sea levels, land use modifications, and fluctuations in the densities of fishing stocks. This project provides longitudinal insights into the resilience of fisheries by studying the determinants of fishing behavior and outputs over the past two millennia in a coastal mangrove wetland. The research leverages diverse archaeological methods to consider multiple hypotheses for sharp declines in the productivity of the ancient fishery. More generally, the project reveals the potentially complex and dynamic relationships between ecological variables, political factors, and the culture and demography of the human populations. The archaeological methods are complemented by observations of modern fishing behavior, which provide holistic insights into the long-term resilience of past subsistence behavior. Multiple students contribute to the research, and a central aim of the project is to develop a collaborative museum exhibit that contextualizes the findings. The project also convenes a workshop to advance sustainable management of the fishery.Drawing on perspectives from human ecology, the research examines fluctuations in the productivity of a mangrove fishery as a function of multiple related variables, including intrinsic dynamic variation in the ecological structure of lagoons, the political organization of local communities, and the alternation of adjacent land for agricultural activities. Complemented by sediment cores, archaeological excavations yield diverse evidence for studying the productivity of the fishery. Radiocarbon samples establish the chronology of the site, and the remains of crustaceans and pollen and other botanical remains help to characterize ecological changes over time. Zooarchaeological analysis of middens provide insights into the varying harvests of different fish species over time. Additional analyses of ceramics and stone tools are used to assess variation in social and political variation and dynamic patterns of agricultural subsistence. Collectively, these data provide insights into the causes and consequences of changes in the productivity of small-scale fisheries. In addition to contributions to archaeological theory, the findings of this study inform management strategies of contemporary fisheries. The project also contributes to the training and educational of diverse early-career scholars.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.
