In recent decades freshwater lakes have seen an increase in human presence. A common byproduct of this human presence is eutrophication, which readily results in harmful cyanobacteria (CB) blooms. In this work we propose a model that couples the socio-economic and ecological dynamics related to cyanobacteria systems. The socio-economic dynamics considers the choices a human population makes regarding whether or not to mitigate their pollution levels. These choices are based on various costs related to social ostracism, social norms, environmental concern and financial burden. The coupled model exhibits bistable dynamics, with one stable state corresponding to high mitigation efforts and low CB abundance, and the other to low mitigation efforts and high CB abundance. Furthermore, we consider social interactions among a network of lakes and present dynamic outcomes pertaining to various associated costs and social situations. In each case we show the potential for regime shifts between levels of cooperation and CB abundance. Social ostracism and pressure are shown to be driving factors in causing such regime shifts.

近几十年来，淡水湖泊的人类数量有所增加。这种人类存在的一个常见副产品是富营养化，这很容易导致有害的蓝藻 (CB) 大量繁殖。在这项工作中，我们提出了一个模型，该模型将与蓝藻系统相关的社会经济和生态动力学相结合。社会经济动态考虑了人类在是否减轻其污染水平方面做出的选择。这些选择基于与社会排斥、社会规范、环境问题和经济负担相关的各种成本。耦合模型表现出双稳态动力学，一种稳定状态对应于高缓解努力和低 CB 丰度，另一种稳定状态对应于低缓解努力和高 CB 丰度。此外，我们考虑湖泊网络之间的社会互动，并呈现与各种相关成本和社会状况相关的动态结果。在每种情况下，我们都展示了合作水平和 CB 丰度之间的政权转变的潜力。社会排斥和压力被证明是导致这种政权更迭的驱动因素。
