The FORager dynamics in Global Ecosystems (FORGE) model is a cutting-edge computational tool designed to simulate the intricate interactions between hunter-gatherer populations and their surrounding environments. This innovative Earth system model provides a global, gridded framework to understand how human activities, such as hunting and gathering, influence and are influenced by non-human ecosystem components. It represents a significant advancement in human-environment modeling by directly coupling physically-resolved human dynamics with ecological processes, offering a unique perspective on long-term human-ecosystem co-evolution and sustainability research.
