Water challenges are complex, requiring integrated solutions and a social legitimate planning process. Assuming water flows as physical, social, political, and symbolic matters, it is necessary to entwining these domains in specific configurations in which water users, managers, and decision-makers could be directly involved to lead to one of the current main challenges: climate change.

The ModFaBe project (Modelling individual farmers behaviours in Coupled Human Natural Systems under changing climate and society) aims to increase the robustness of decision-making processes in Coupled Human-Nature Systems (CHNS) by modelling farmers’ perception and adaptation capacity to climate change. Considering that climate change and water resources management represent two necessarily interdisciplinary topics in which the natural and social sciences must be integrated, the MODFABE’s core is to combine observational data (farmers’ perception) into simulation models to increase the rationality of farmers’ interventions in the decision-making processes based on multiple competing purposes and a multiobjective context.

By combining qualitative and quantitative methods and evidence-based analysis from social learning process, new knowledge about (1) increasing adaptive capacity, (2) building trust and collaborative problem solving, and (3) ensuring better co-working will be highlighted in the Muzza system as a test zone.

A key question in today climate change adaptation research will be addressed: Can behaviour modelling help farmers to promote actions and anticipate decisions to adapt to climate change and become more sustainable and resilient? Modelling human behaviour can be used as a safe laboratory for policy experimentation, testing the effectiveness of strategies and policy measures on climate change.
