This paper explores the integration of R-IO Suite, a knowledge-based decision support system, with GAMA, a multi-agent simulation platform, to improve situational awareness and crisis response in a changing climate. This approach enables decision-makers and local communities to better understand, anticipate, and mitigate crisis impactsby combining real-time data modelling and predictive simulation.Although the proposed framework has been conceptually defined, its implementation and validation remain openkeychallenges. The French ANR-funded ATEsT project aims to overcome major technical obstacles?interoperability, semantic alignment, andtemporal synchronisation?through concrete use cases. Future work will focus on implementing and testing this integration in realistic crisis scenarios,such as mega-fires and flash floods across different territories,to assess its effectiveness in improving decision-making processes and citizen engagement. 120 ; 021 ; 122
