Red Social Innovation explores how shifting from traditional weather forecasts to impact-based forecasting empowers humanitarian organizations to act proactively before disasters strike. By focusing on the potential consequences of extreme weather events – such as damage to homes or threats to livelihoods – rather than merely predicting the events themselves, the Impact-Based Forecasting (IBF) Portal enables more targeted and timely interventions. The article highlights the collaborative efforts of the Red Cross Red Crescent Movement and the wider humanitarian sector in implementing anticipatory action programmes that utilize IBF to protect vulnerable communities. It also underscores the importance of partnerships between meteorological agencies and humanitarian actors to develop forecasts that are both accurate and actionable. Through case studies and practical examples, the piece illustrates how the IBF Portal is revolutionizing disaster preparedness and response, ultimately aiming to reduce the human and economic toll of climate-related hazards.
