Abstract

This paper investigates how introducing explicit spatial features alters phase-transition dynamics in economic land-use models. Building upon a recent hybrid agent-based and equation-based model of agricultural land-use transitions, we incorporate real-world geographical constraints (irreversible urbanization, coastal development bias, and river valleys) observed in the Alpes-Maritimes region of Southeast France. Our simulations show that while coastal urbanization dampens the potential for agricultural resurgence, natural valley corridors counteract this effect by fostering new agricultural clusters. These findings highlight the complex interplay between economic dynamics and spatial constraints, suggesting that policies fostering agricultural revival must account for territorial heterogeneity.
