Spatial Management of Invasive Species: Pathways and Policy Options
研究构建了一个两区域生物经济模型，分析不同传播途径下检查、清除和可持续土地管理等措施对入侵物种控制的影响，发现区域、途径和控制措施间的非线性交互显著影响最优管理策略。
In addressing the problem of invasive species, decision makers have a variety of options, each targeting different aspects as it evolves over time and space. We develop a 2-region bioeconomic model that includes several transmission pathways that spread the invader. Within each region, inspections, removal efforts, and sustainable land management practices, including habitat restoration and less damaging production activities, are available to the regulator. We investigate the implications of different transmission pathways and second-best policies on the control patterns and invasive populations. Second-best settings where certain controls are not available to the regulator result in large distortions on the optimal use of the land. Overall, we find that non-linear interactions between regions, pathways, and controls are significant determinants of the optimal management of invasive species.
