Water resources management needs true understanding of food and energy management with focus on extraction of groundwater. It should be tried to manage these resources in sustainable framework and due to impact have on each other. Water-Food-Energy nexus is based on sustainability concepts and supply and demand of resources exploitation water-energy-food and should be quantified with scenario analysis. six different Indexes have been accounted in this paper. In addition to the four sustainability indexes virtual water trade and CO2 emissions are other indexes have been accounted. Virtual water trade in scale of all Crops and each individual crop varies. In all crops it doesn’t affect the Lenjanat sub-basin and it has less important factor. But for each individual crop it could be analyzed in more detail. CO2 emission is another important factor that should be mentioned. GHG emissions generally and CO2 emission in particular that comes from the exploitation of fossil fuels can be mentioned as environmental costs and the impact that they have on ecosystem. Despite of the indexes evaluated and, on the fact, that the potential of creating solar PV farms of Lenjanat it had been tried to make scenarios. 8 scenarios where be established in combination and singular manner that focuses on sustainability and utilization of the resources. One of the most important issues in in ordering and selection of the scenarios is to use multicriteria decision making (MCDM) methods to have better understanding of the selection. Two important aspects in this method should be considered, First the determination of the Criteria/indexes weights and in manner Objective and Subjective fashion. After determining the weights, utilizing the appropriate method to rank the scenario is inevitable fact. Also, it has been some endeavor to take MCDM method that shows the interactivity between Indexes. Lenjanat Sub-basin is one
