DISPLACE California

DISPLACE is an open-source, agent-based, spatially explicit bioeconomic modeling framework designed to simulate the behavior of individual fishing vessels, developed by François et al. (2014).

Here we present an specific DISPLACE application used to evaluate the potential impacts of California’s offshore wind energy development lease areas on the DTS fisheries operating off the coast of California. You can access the repository notebook here.

Note: The data in this repository are entirely example-based and do not represent real fisheries information. They are provided solely to demonstrate methods and workflows that can be adapted for real-world applications.

Quick Setup & Run

1. Adjust the installer directory in the directory parameter of the generate_dis_run_files function within functions_routines.R.
2. For a quick execution and model run to test whether it can run on your machine, execute:

   source(here::here("r/functions_routines.R"))

3. We recommend reviewing the entire repository to understand the inputs and processes in more detail before executing.
