Résumé
Drought management in France is implemented locally. Due to discrepancies between assessment of drought situation by managing agency on one hand and water users on the other hand, as well as to uncertainty in measures and benchmarks, its efficiency is limited. We propose in this paper an agent based model designed to represent the suitable indicators of drought at the suitable spatial scale for any category of stakeholders. Initial test of the model show its suitability to explore sensitivity of efficiency of drought management setting according to its context: population of water users and their attitudes to water restriction rules as well as practical details of implementation.
