The WaterTransformation emphasizes the critical role of water as a finite resource facing various challenges such as droughts, pollution, and climate change. It calls for a global shift in water management towards systematic, circular, and robust strategies, termed as “water transformation.” The initiative, involving experts from Europe and Japan, seeks to redefine water as a social, economic, and dynamic growth engine. The focus is on creating value for businesses and communities by optimizing water resources, promoting circular economy principles, and engaging with stakeholders. The ultimate goal is to contribute to achieving Sustainable Development Goals (SDG) and environmental objectives through innovative water governance models. Key strategies include leveraging digital technologies for smart water management, promoting sustainable practices, advocating data-driven decision-making, supporting water reuse, implementing sustainable infrastructure, and fostering collaboration between IT, industry, and communities. The aim is to increase awareness and acceptance of responsible water resource management within the local economy and society.
