Competition for water resources is a growing concern especially in the context of climate change/variability and changing land-use patterns. There is little understanding of the human response to the dynamics of water-balance-evolution, including spontaneous or unexpected behaviours. Conflicts emerge as society adjusts with the changing hydrological conditions which affect the landscape/waterscape. The PhD research is coined under three pillars of knowledge; 1) River-Basin Management, 2) Socio-Hydrology, and 3) Gaming methodology. The overall objective is to explore the dynamics of human-water systems under pressure from climate and land-use changes. Serious games will be used as learning tools and in exploring decision-making processes among the local communities.
