Water, energy, and food (WEF) securities are sensitive keys for building a sustainable economy. In fact, a high level of interconnectedness exists between the three resources. These resources form a nexus which itself is affected by external factors such as a growing population, changing economies, international trade, governance, health impacts, environmental impacts, and climate change. Recognizing the intimate connection between these resources is necessary to move to more integrative approach for resource management. QEERI is currently engineering a comprehensive tool, specifically tailored for Qatar, that is aimed at identifying sustainable resource management strategies governed by the water-energy-food (WEF) nexus. This tool will incorporate the following features: -The tool will allow the creation of multiple scenarios composed of different variations of local food production levels, water sources, energy sources, and food import sources. -The output will include a holistic summary of resource needs for a given scenario, including water, energy, land and financial requirements, as well as identify environmental impacts. Current and foreseen bottlenecks could thus be recognized, leading to the initiation of resource management action plans. With this tool in place, QEERI offers an innovative sustainability model that could be adopted locally as well as in similar arid environments.
