In an era marked by escalating environmental issues, the convergence of sustainability and energy efficiency becomes a promising avenue for solutions. This research delves into this intersection, with specific emphasis on Iraq and the wider Middle East region. In these arid environments ensuring food security, managing water scarcity, and addressing energy demands are pressing priorities, the current work examines three crucial domains that present innovative approaches to address these challenges. The practice of indoor vertical farming has the potential to address future concerns regarding food insecurity by simultaneously decreasing land utilization and reducing reliance on the environment. Nevertheless, the substantial challenges lie in its elevated energy consumption and consequential environmental impact. This research examines the feasibility of utilizing Concentrating Solar Power (CSP) to power vertical farming in the arid regions of Iraq, taking advantage of the ample solar resources available. The study employs the system advisor model (SAM) to analyze the potential relocation of a commercial CSP plant from Seville, Spain, to six different locations in Iraq. The evaluation takes into consideration various factors, including implementation costs, energy production, and water usage. It is worth noting that the zones of Haditha and Ar Rutba demonstrate the highest annual energy output, exceeding that of Seville's original plant. In addition, the practice of vertical farming, particularly when focusing on Romaine lettuce as a representative crop, showcases the possibility of achieving significantly greater yields in arid regions when compared to traditional farming methods. The subsequent points outline the significant findings of this research segment: ● Vertical farming is a sustainable solution for agriculture, maximizing space and water efficiency. ● CSP can address the high energy consumption of vertical farming. ● Six locations in west Iraq are suitable for CSP plants due to favorable conditions. ● Techno-economic analysis showed that Iraq's CSP outperforms Spain's in some locations. ● Vertical farming in Iraq can significantly increase lettuce yields, but it has higher energy requirements. ● The study can aid in reducing food insecurity and dependence on fossil fuels in arid regions. The findings highlight the significance of CSP technologies in promoting sustainable agriculture in Iraq and provide valuable insights for policymakers and stakeholders who are interested in cost-effective and energy-efficient solutions. It is crucial to reduce the reliance on fossil fuels in the agricultural sector. This research additionally examines the economic viability of incorporating solar energy photovoltaic (PV) into irrigation systems in the Middle East. Simulation models were used for four different locations, demonstrating that Egypt and the United Arab Emirates are particularly suitable for solar-powered irrigation. In Egypt, there is a quick return on investment, indicating its profitability, while access to solar power greatly benefits the United Arab Emirates. The integration of solar energy into irrigation networks in Egypt proves both feasible and financially rewarding, potentially serving as a blueprint for sustainable practices throughout the region.Type
