Economic Analysis of Invasive Species Risk Using A Spatial Integrated Model

点击翻译按钮获取中文摘要

Invasive species often compete with native species causing various economic and ecosystem loss such as damages to agricultural crops. Therefore, efficient and effective invasive species management is an important issue for achieving a sustainable society. Once invasive species invade and establish, they spread to neighboring areas over time and cause extended damages. However, an appropriate management for controlling their spread, can slow down the speed of spread or can stop their spreading at least temporally. Therefore, in order to control their spread cost efficiently, it is necessary to apply dynamic and spatial management allocation problem framework. We integrate management allocation model and a Cellular Automaton model that project the spread of invasive species and search for the efficient management strategy for mitigating the spread of invasive species.
