Water scarcity is an escalating global crisis that affects billions of people, with profound implications for public health, ecosystems, and economic development. This problem is due to climate change, population growth, urbanization, and poor water management. Solving this challenge requires knowledge of its causes and ways of using water resources effectively and sustainably. Therefore, this study aims to identify measures for efficient water management at the technology, policy, and community levels. These approaches are meant to reduce the effects of water shortage and increase access to fresh water. The study includes a systematic literature review, case studies, and a conceptual model based on technology, policy, and community-based interventions. The study calls for enhanced Integrated Water Resources Management (IWRM), state-of-the-art water recycling, active community involvement, and effective adaptive governance to combat water scarcity conditions. However, the study also reveals challenges such as political will, lack of funds, and inadequate water governance. This research provides novel findings in sustainable water management by integrating theory and practice. The paper offers valuable suggestions for policymakers, water institutions, and local governments and stresses the multi-level and multi-agent governance approach. The results are timely as they are under the backdrop of the United Nations Sustainable Development Goals and, more specifically, the goal of clean water and sanitation (SDG 6). In filling the knowledge gap on sustainable practices, this study presents a framework for future research and practice addressing global water scarcity.
