Short summary

We present a new modelling framework that combines simulations of environmental change and human decision-making in an integrated approach. It allows researchers to explore how farming decisions affect land, water, and climate, and how these environmental changes influence future decisions. By connecting people and nature, it helps investigate food security, climate adaptation, and sustainability challenges, and supports the development of more realistic scenarios of future environmental change.
