A Single-Agent Urban Coastal Adaptation Model: Adaptive decision-making within the VIABLE modeling framework

We develop a single-agent-based model in Netlogo of a coastal city facing climate change, using the VIABLE framework. The coastal city is threatened by damages from sea level rise and subsequent extreme sea level events. The agent, representing an urban planner, uses capital generated by the city to mitigate these damages by investing into one of two adaptation options available to it- developing coastal defenses or relocating the vulnerable coastal territories of the city inland. As the simulation progresses, gradually rising sea levels and randomly occurring extreme sea level events incur damages, and the agent alters its investments to optimize its value, resulting in dynamic reactive behavior. We track the response of this agent to the changing system through its investment patterns.
