“Optimizing Desalination for Regional Water Systems” by Prof. Mashor Housh, School of Environmental Studies, of the Faculty of Social Sciences, discusses the challenges faced by arid regions in managing water supply systems amid increasing demand and water scarcity. The article, published in the Journal of Cleaner Production, emphasizes the importance of integrating seawater desalination into these systems. It proposes a two-stage optimization approach to address decision timelines and uncertainty, using the Israeli national water supply system as a case study. The study also incorporates stakeholder preferences through multicriteria decision analysis, aiming to enhance sustainability and efficiency in regional water management.
