Foreword Many parts of the world are experiencing increasing climate risks. This is partly due to climate change, which drives the increased intensity and frequency of extreme weather events, combined with decision-making processes that place people and infrastructure in harm’s way. Managing these risks requires more effective discourse on what our societies value and greater emphasis on evidence- based decision-making to safeguard our environment, people, communities, culture, infrastructure and business operations. This latter group has not been adequately engaged regarding their emerging vulnerability to climate-driven impacts or their potential role in providing solutions. This white paper emphasizes the value of a transdisciplinary approach by engaging businesses in early warning systems (EWS). This can be achieved by bringing together scientific knowledge, advanced technological innovations and favourable policies to develop actionable solutions. Aligning with the priorities of the Australian National University (ANU), this paper provides a comprehensive approach to engaging businesses in EWS. It focuses on integrating diverse strategies and collaboration models to achieve the goals of the Early Warnings for All initiative. The paper demonstrates that catalysing business involvement in EWS goes beyond financial investments or supporting National Meteorological and Hydrological Services (NMHS) communication of warnings. It also encompasses effective knowledge sharing and the co-creation of innovative solutions to enhance the accuracy and reach of real-time warnings linked with action plans. Positioning businesses as partners and innovators in the EWS value chain enhances knowledge about hydrometeorological hazards and risk reduction, enabling businesses to make more informed decisions. This collaborative model also encourages businesses to explore market opportunities and cater to their operational needs while achieving broader societal goals. As we move forward, there will be substantial benefits from harnessing the knowledge, experiences and resources of different stakeholders to develop more effective and efficient EWS that protect people, the planet and the economy and hence contribute to the success of the Early Warnings for All initiative.Mark Howden Director, Institute for Climate, Energy and Disaster Solutions, Australian National University Catalysing Business Engagement in Early Warning Systems 5
