LIFE BAETULO: Integrated Early Warning System for Climate Change Adaptation in Urban Areas

Coastal cities face escalating threats from climate change, where extreme weather events—from flash floods to heatwaves—disrupt daily life, damage infrastructure, and endanger public health. Addressing this urgency requires real-time, adaptive solutions that bridge the gap between scientific forecasting and on-the-ground action. In the metropolitan area of Barcelona, a pioneering initiative has emerged to transform how urban centers predict, monitor, and respond to climate hazards, empowering both authorities and citizens with data-driven tools to build resilience.

Challenge: Fragmented Climate Risk Response in Vulnerable Urban Areas
Urban coastal regions like Badalona, near Barcelona, are on the frontlines of climate change, grappling with a convergence of hazards—fluvial flooding, storm surges, heatwaves, air pollution, and wildfires—that strain traditional emergency systems. The lack of integrated tools to anticipate and manage these risks leaves cities reactive rather than proactive, increasing exposure for residents, critical infrastructure, and local economies. Vulnerable populations, including the elderly, low-income communities, and outdoor workers, face disproportionate threats from extreme heat and flooding, while tourism-dependent areas like beaches suffer from pollution spikes and erosion.

Without a unified approach, risk managers struggle to prioritize actions during compound events (e.g., simultaneous heatwaves and floods), leading to delayed responses and higher recovery costs. The financial toll is staggering: climate-related disasters in European cities already cost billions annually in damages, with projections worsening as temperatures rise and sea levels creep higher. Existing systems often operate in silos—weather forecasts, flood models, and air quality alerts rarely communicate—leaving gaps that exacerbate crises. For coastal cities, where 40% of the global population resides, the stakes extend beyond immediate safety to long-term habitability, economic stability, and ecosystem health.

An Integrated Digital Platform with Real-Time Monitoring and Citizen-Centric Tools
The solution combines advanced weather forecasting, sensor networks, and historical modeling into a single digital platform to automate hazard detection and emergency protocols:

1. Planning & Hazard Identification: The project mapped out climate risks threatening urban areas, from floods and heatwaves to storm surges and wildfires, using historical data and hazard models. They designed an all-in-one early warning system to integrate these threats into a single platform, ensuring no risk slipped through the cracks.
2. Data Integration & Real-Time Monitoring: The team deployed network of sensors (weather stations, air quality monitors, wave gauges, cameras) and tapped into Catalan weather forecasts to feed live data into the system. Offline modeling tools (like flood-risk street maps and heat island simulations) were embedded to predict impacts—such as which streets would flood or how long pollution would linger after storms.
3. Automated Alerts & Emergency Protocols: A digital dashboard for risk managers was built to automate alert thresholds (pre-alert, emergency) and trigger checklist-style protocols, assigning tasks to city departments (e.g., evacuations, road closures). The system also logged past events, turning every crisis into a lesson for faster future responses.
4. Citizen Engagement via Mobile App: To empower residents, they launched a free public app that pushed real-time hazard alerts alongside actionable tips. The app’s gamified rewards boosted awareness, while a cost-benefit analysis proved the system’s 14x return on investment, making it a no-brainer for climate-resilient cities.

Unique Selling Proposition
What makes this project a game-changer is its real-time, all-in-one early warning system, which doesn’t just predict disasters but maps vulnerable zones and automates emergency responses, slashing reaction times when seconds count. The project’s 14:1 cost-benefit ratio proves that proactive adaptation isn’t just moral—it’s economically brilliant, saving 14 euros for every 1 euro spent by preventing damage rather than cleaning up after disasters. In a world where climate hazards are accelerating, BAETULO isn’t just a tool—it’s a lifeline for urban resilience, showing how tech and community action can outpace the chaos before it’s too late.
