Bioeconomics of Managed Relocation
研究在气候变化下，如何通过管理性迁移（将受影响的物种移到历史范围外的新地点）来优化生物资源，使用空间动态生物经济模型求解最优迁移政策，并分析迁移对目的地生态系统的影响。
Managed relocation is a biological resource management intervention that moves a portion of a species negatively affected by climate change to sites outside of its historic range where the species’ productivity is expected to be higher. We numerically solve for the optimal managed relocation policy in a spatial-dynamic bioeconomic model. The model includes three sites where climate change causes the local productivity of a beneficial species to change over time. The optimal policy is characterized by complex transient dynamics that reflect productivity trends, the local benefit of the species, and the cost of relocation. Given concerns about the impact of a relocated species on destination ecosystems, we consider the implications of blocking relocation to a site. We also compare optimal managed relocation to the relocation policy that achieves a future population distribution with the least investment.
