HARMONI · HAZARD ASSESSMENT AND RISK MANAGEMENT OF NATECH EMERGENCIES WITH CROSS-COLLABORATION OPPORTUNITIES

HARMONI addresses the growing complexity of NaTech disasters by developing a comprehensive platform to enhance prevention, monitoring, and response for critical infrastructures (CIs). The platform will integrate existing data and lessons learned into a unified Knowledge Graph (KG) and the information gathered will serve for the creation of a database of Standard Operating Procedures (SOPs). The tools that will be offered by HARMONI are: 1) PREVENTION: Digital Twins (DTs) for CIs, enabling the modeling of cascading effects and worst-case scenarios to inform prevention and mitigation strategies. 2) MONITORING: HARMONI combines advanced remote sensing algorithms, UAV-SAR imaging, and on-site data collection, to deliver real-time monitoring and early warnings of vulnerabilities, while 3) ACTION/RESPONSE: will be guaranteed by its Hybrid NaTech Decision Algorithm (HNDA) that integrates Federated Learning, human expertise, and SSH insights to recommend actionable SOPs tailored to evolving disaster scenarios. This ensures a holistic decision-making process, aligning technical capabilities with social and ethical considerations.The project includes six use cases, showcasing its technologies in diverse NaTech scenarios, including a cross-border collaboration use case to validate interoperability and scalability with existing systems. By fostering cooperation with ESA FutureEO initiatives and EU frameworks, HARMONI supports knowledge sharing and alignment with international standards. Ultimately, HARMONI aims to strengthen resilience, reduce disaster impacts, and provide innovative, interoperable solutions to NaTech crises, supporting safer, more sustainable management practices across Europe and beyond.
