Few tools exist to aid decision-making regarding the management of water, food, and energy resources at the watershed level. CGE-SyDWEM is developed to capture the cross-sector interactions and feedback among economic, energy, and water systems, which can help policymakers identify the possible co-benefits or trade-offs across different systems and design effective policies and measures.

Figure below illustrates the conceptual integration of the CGE and SyDWEM models. The IMED|CGE (Integrated Model of Energy, Environment and Economy for Sustainable Development | Computable General Equilibrium) model includes a production block; a market block with domestic, government, and household income and expenditure blocks; and international transactions. The CGE model can simulate GHG emissions from energy use, macroeconomic impacts (e.g., GDP, government expenditure, welfare, import, and export), detailed industrial outputs, and carbon intensity for each sector under carbon mitigation strategies.The System Dynamics and Water Environmental Model (SyDWEM) is used to simulate socio-economic subsystems, water infrastructures, and receiving water systems at the sub-watershed level. It includes five modules: (1) Population/GRP (Gross Regional Product, i.e., GDP for regional analysis) module; (2) Water demand/pollutant generation module; (3) Water supply module; (4) Sewer and WWTPs module; and (5) Receiving water module. More details of each module can be found in Su et al. (2018), Su et al. (2019) and Su et al. (2023).
