The Clim4Cast project developed a transnational strategy for raising awareness about compound drought, heatwave, and wildfire (DHF) events in Central Europe. A key part of this work was the creation of a unique database documenting DHF events and their impacts between 2000 and 2023 across the partner countries. The database helps illustrate how climate extremes affect society, agriculture, forests, water resources, and other sectors, making climate change impacts more understandable for stakeholders and the public. It also provides an important scientific basis for evaluating how climate change influences the occurrence and severity of compound climate events across Central Europe. To improve understanding of DHF impacts, the project developed a new severity index allowing comparison of events across countries and sectors. Additional activities focused on climate change attribution analyses and stakeholder surveys exploring public perception and communication of climate risks. Together, these outputs support more effective climate communication, awareness raising, and preparedness strategies tailored to different regional contexts across Central Europe.

The Clim4Cast project has developed a solution for integrated multi-temporal forecasting of drought in Central European countries, leveraging partners' expertise in drought monitoring. This solution enhances existing national platforms by providing regionally-specific, multi-temporal forecasts, helping to improve preparedness and response to drought events across the region.

The heatwave forecasting system integrates numerical weather prediction with real-time data to provide accurate heatwave predictions. It features a digital toolbox with open-source data and models, enabling spatially explicit forecasts that are accessible to all participating countries. By incorporating these forecasts with national weather monitoring platforms, the system facilitates timely early warnings and enhances regional cooperation and preparedness.

The proposed solution focuses on a collaborative effort to develop an integrated forecasting model for fire weather in Central Europe. By leveraging multidisciplinary expertise and resources, the project creates a comprehensive tool tailored to the diverse climatic conditions of the region. The cooperative approach addresses the complex, interconnected nature of fire events, enhancing resilience and preparedness across Central European countries.

The Clim4Cast project established a cross-border operational framework for monitoring and forecasting droughts, heatwaves, and wildfire risk across Central Europe. Project partners jointly harmonized methodologies and developed an operational system for the daily calculation, sharing, and visualization of DHF forecasting products. The final regional platform, available at https://clim4cast.eu, provides real-time visualization of climate extremes with a strong focus on cross-border regions and harmonized interpretation of risks. The platform integrates monitoring and forecasting products, interactive mapping tools, multilingual content, and regularly updated information on major DHF events across partner countries. All project partners contributed to testing, validation, national customization, and translation of the platform outputs. Pilot activities confirmed the operational applicability of the forecasting products under different climatic and institutional conditions. The project significantly strengthened cross-border cooperation, data sharing, and operational collaboration among meteorological institutes, research organisations, and stakeholders, creating a long-term basis for regional climate resilience and coordinated response to compound climate extremes.

The Clim4Cast project developed National Action Plans focused on improving preparedness and proactive responses to droughts, heatwaves, and wildfires (DHF) across Central Europe. The action plans were created through close cooperation with national stakeholders, including public authorities, operational institutions, sectoral agencies, and experts from different fields. National consultations organized in all partner countries helped identify country-specific vulnerabilities, implementation barriers, and priority measures reflecting different legal, institutional, and environmental conditions. Based on this feedback, each partner country prepared a tailored National DHF Action Plan adapted to its own needs and operational context. The final Action Plans include recommendations for improving climate resilience, risk prevention, communication, and preparedness related to compound climate extremes. Together, they provide a practical framework supporting long-term adaptation efforts, stronger cross-border cooperation, and more coordinated responses to climate-related risks across Central Europe. As part of the Clim4Cast activities, a scheme for proactive responses to droughts, heatwaves, and wildfires (DHF) has been developed and is now available as project deliverable D.3.2.1. This deliverable presents a conceptual framework for proactive actions in response to DHF events, based on early warnings. It also proposes an institutional setup to address all stages of DHF response. The scheme will serve as a foundational resource for discussions during national stakeholder consultations to be organized in each participating country.
