The document outlines the significance and methodologies of agent-based modeling (ABM) in economics, tracing its origins from cellular automata and its emergence as a popular modeling tool for complex systems. It details various approaches to ABM, including deductive, methodological, and phenomenological, and emphasizes its application in fields like small-scale irrigation and drought adaptation. The conclusion stresses the need for further research to enhance ABM's calibration and validation in socio-hydrological contexts.
