Social changes such as growing population, urbanization, globalization, and economic growth, compounded with uncertainties due to climate change are expected to result in substantial shifts in the demand for food, energy, and water. Food, energy and water resource systems are tightly interconnected. Addressing challenges facing any of these resource systems requires a holistic understanding and quantification of the existing interdependencies and trade-offs. This study is aimed at analyzing FEW nexus modeling tools with a specific focus on addressing issues of water management through a nexus lens. In particular, an exploratory approach is taken to assess available FEW nexus modeling tools to determine their accessibility, knowledge gaps, and potential for including aspects that provide better insight into the nexus such as water quality, futuristic scenarios due to climate change, and varying scales within the nexus. A case study in an agricultural watershed in northeastern Indiana is presented which builds on the WEF Nexus Tool 2.0 framework and assessment criteria. For this case study, spatial and temporal analysis based on SWAT was implemented. This provided a water quality component to the framework enabling a more representative analysis of the FEW nexus.
