An agent-based simulation testing the impact of water allocation on farmers’ collective behaviors

Many negotiations take place between farmers, water suppliers, public servants, and environmental-ists to allocate water resources between users in different areas. However, few negotiations quantify the consequences of alternatives solutions. Models that are used are often oversimplified and only take into account elements that are easy to calculate, or they are too complex to be used for negotia-tions in real time. In all cases, they do not consider the heterogeneity of decision makers.The authors demonstrate that agent-based modeling could help these negotiations by showing the consequences of water allocation rules with respect to different criteria
