Jordan Water Project
In arid regions throughout the world, water system security is at a tipping point due to a confluence of drivers that include severely limited water supplies, rapid population growth and demographic shifts, climate change and variability, transboundary competition for shared freshwater resources, and institutional dysfunction. The overarching challenge is to sustain the human-natural system in the presence of rapid environmental and socioeconomic change. This interdisciplinary effort is aimed at developing a new approach to evaluate policies to enhance sustainability of freshwater resource systems. Our research is focused on Jordan, which is one of the ten water poorest countries in the world.
Past policy evaluation modeling efforts to identify effective interventions in stressed water systems have been limited. Notably, such models have largely ignored institutional complexity in management decision-making with results divorced from reality. Our work will adopt a multi-agent modeling framework to allow for the incorporation of institutional complexity in evaluation of policy instruments aimed at improving water security in Jordan. The model will employ a modular approach, integrating biophysical modules that simulate natural and engineered phenomena (e.g., groundwater-surface water flow, reservoir storage, network routing, salt balance, and crop yield) with human modules that represent behavior at multiple scales of decision making. The human modules in turn will adopt a multi-agent simulation approach, defining agents as autonomous decision makers at the government, administrative, organizational, and user levels. Our ultimate goal is to construct a suite of policy intervention scenarios that will form the basis for analysis of freshwater sustainability.
