Tóm tắt: Water is essential for all aspects of life. Its finite availability requires an efficient and equal water allocation for different uses, particularly when there is a growing competition from increasing population and unprecedented climate change impacts. During drought periods when water supply is unable to meet the business-as-usual demand, an equitable water allocation priority order is essential to ensure that priority needs of society are met. This study proposes a basin water allocation framework (BWAF) based on the Analytical Hierarchy Process (AHP) and Decision Analysis Module for Excel (DAME) to provide an evidence-based toolset, supporting decision-making processes in determining how to optimally allocate water among different water users. The framework allows the users to customize the scenarios, criteria and variants that produce fair priority order results in accordance to the identified objectives. The framework is examined in a transboundary Vu Gia Thu Bon River basin, Vietnam where two provinces QuangNam and DaNang share the same river basin. Considering only surface water resources and evaluating the economic efficiency of four different sectors – cultivation, animal husbandry, industry and aquaculture, the framework provides different priority orders for each province and the entire basin in water shortage months. Findings can not only further contribute to the literature on drought risk management frameworks but also provide a useful and easy-to-use toolset for decision makers to respond and adapt to droughts in practice.
