Research Article // SD-DSS model of sustainable groundwater resources management using the water-food-energy security Nexus in Alborz Province
By Mehdi Rahmani, Seyed Habib Musavi Jahromi and Hossein Hassanpour Darvishi. This study conducted dynamic modelling of sustainable ground water resources management based on the Water-Food-Energy Security Nexus (WFESN-SD) and analyzed sustainable groundwater resources management solutions considering the pattern of variations in population, economic growth, and renewable energy resources development on water stress and groundwater resources security. To this end, after identifying the complications in Water-Food-Energy Nexus and quantifying them using time series data, the dynamic model of WFE was designed.

Unbalanced development of Alborz Province in recent years has amplified groundwater security crisis as well as water stress. This study conducted dynamic decision support system modelling of sustainable groundwater resources management based on water-food-energy security Nexus (WFESN-SD-DSS). Using the results, the scenarios were designed in three categories of solutions: 1- Groundwater resources security; 2- Groundwater resources security; and 3- Groundwater resources security. The WFEN-SD-DSS model findings implied that combined policies represented the best solution and these included: Aquifer artificial recharge of 10 million cubic meters per year; control of well water usage; exploitation and reuse of graywater to supply 10% of agricultural water; 10% development of irrigation efficiency using novel irrigation systems; 10% reduction of agricultural waste; 10% development of the performance of agricultural products by modifying seeds, conserving plants; 5% reduction of electrical energy dissipation in combined cycle power plants; and development of solar water pump systems in agriculture sector.
