HORIZON-CL3-2026-01-DRS-05: Modeling Climate Security and Cascading Crisis Scenarios

1. Bridging the Gap Between Climate Risk and Civil Security

The HORIZON-CL3-2026-01-DRS-05 call forces a crucial paradigm shift in disaster management funding: the transition from calculating isolated climate risks to confronting comprehensive climate security emergencies. As extreme weather events systematically degrade critical infrastructure across borders, European preparedness requires an evolution beyond static, single-hazard modeling. Droughts instigate agricultural collapses, which inevitably compound into supply chain disruptions and acute social unrest. Civil defense mechanisms, public institutions, and NGOs desperately need methodologies to navigate these complex, compounding emergencies.

This €4.5 million Innovation Action (IA) mandates the creation of sophisticated pre- and post-crisis scenario architectures. It requires multi-disciplinary consortia to integrate high-level climate models with tangible civil security mechanisms. Success depends perfectly on an unyielding adherence to actionable outcomes—transforming advanced data into operational decision-support platforms.

Strategic Call Snapshot: Unfiltered Mandate

"HORIZON-CL3-2026-01-DRS-05: Climate security and civil preparedness – new ways to develop pre- and post-crisis climate-change related scenarios for a more resilient Europe. Call: Civil Security for Society 2026 (Horizon Europe Cluster 3) Type of Action: Innovation Action (IA) Opening Date: 6 May 2026 (indicative) Deadline: 5 November 2026 at 17:00 Brussels time Indicative Budget: €4.5 million. Expected Outcome: Improved understanding and modelling of compound and cascading climate-related risks and their interactions with other hazards. Enhanced civil preparedness through innovative scenario development and stress-testing methodologies. Scope: Proposals should develop and demonstrate new approaches, tools, and methodologies for creating, validating, and using pre- and post-crisis climate-change related scenarios. This includes multi-hazard, compound risk, and cascading effect modelling that links climate science with security, governance, and societal dimensions. Strong involvement of end-users (civil protection, local authorities, NGOs) and clear pathways to operational uptake are required. Projects should address inclusivity, equity, and the needs of vulnerable populations."

2. Deconstructing the Multi-Phase Scenario Architecture

Developing isolated, pre-crisis assessments will guarantee evaluation failure. The DRS-05 framework demands integrated temporal integration across three distinct timelines. Evaluators require dedicated work packages for each respective phase.

Pre-Crisis Operations (Risk Assessment)

Spanning a 1-to-10-year horizon, this phase asks highly probable hazard queries based upon rigorous modeling structures. Consortia must merge sophisticated multi-variate modeling outposts—utilizing CMIP6 or analogous datasets—to ascertain probability distributions mapping complex phenomena, such as intersecting droughts and subsequent wildfire events throughout critical European geographies.

Acute Crisis Operations (Active Response)

Transitioning from long-term models to an acute hour-by-hour trajectory. Planners must simulate rapid-onset infrastructure collapse. Establishing stress-test parameters—such as modeling real-time power grid failures amidst simultaneous localized flooding and isolated communication blackouts—provides civil defense authorities with unparalleled functional visibility.

Post-Crisis Operations (Recovery Dynamics)

Assessing timelines expanding from initial recovery weeks to multiple years, this phase defines long-term systemic rehabilitation. Methodologies must define land-use restructuring programs, incorporating critical socio-psychological modeling to gauge community acceptance toward permanent relocation paradigms avoiding perpetually vulnerable regions.

3. Mastering Cascading Effects and Security Thresholds

The central innovation engine of DRS-05 operates upon cascading failures. The traditional, isolated hazard report provides minimal utility. A funded application identifies the exact tipping points dictating when a manageable localized flood evolves into an interstate logistics blockade forcing extreme macro-economic disruptions.

Analyzing Threat Multipliers

Your proposal must evaluate explicit security metrics deeply connected to civilian protection:

• Demographic Displacement: Assessing immediate storm-surge evacuation timelines while mapping progressive, slow-onset rural-to-urban migrations triggered by agricultural desertification.
• Resource Friction: Defining severe interstate tensions generated through sudden water-sharing shortages traversing multiple sovereign national borders.
• Socioeconomic Fracture: Implementing granular evaluations detailing how compounding events disproportionately burden linguistically isolated groups or elderly municipal populations.

4. Evaluation Excellence: Methodological Requirements

Meeting the stringent standards of Horizon Europe Cluster 3 demands that qualitative concepts effectively translate into robust quantitative delivery systems.

Science of Scenarios: The Storyline Approach

Evaluators expect a rigorous storyline approach combining climate output algorithms and participatory validation workshops. Proposals failing to accurately reproduce historical macro-events (e.g., the 2025 Central European Floods) utilize inadequate algorithmic scaffolding. Do not attempt to formulate entirely new climate prediction systems. Rather, utilize existing Copernicus Earth Observation architectures to craft a highly developed translation layer specifically optimized to convert complex data into immediate operational directives for frontline NGOs and emergency services.

Designing the Impact Pathway

Integrate the generated scenarios into national or regional risk planning blueprints. Produce highly accessible tabletop exercise systems allowing isolated rural civil defense directors to effortlessly stress-test hypothetical cascading vulnerabilities without requiring excessive external technical facilitation. Providing undeniable economic rationale—such as quantifying exact infrastructural savings achieved by preemptively modifying logistical networks—drastically enhances the overall impact evaluation.

5. Mini Case Study: Modeling Transboundary Crisis Systems

Project Analogue: "CLIMSEC-Scenarios – Continental Transboundary Security Matrices" Composition: Central European Research Institute (Lead), Pan-Regional River Commission, Two Transnational Ministries of Civil Protection, Cross-border Private Hydro-Electric Operator.

The Conceptual Gap: Isolated national security simulations failed to accurately calculate the downstream shockwaves generated by intense localized climate events along extensive multinational waterways.

The Innovative Intervention: The consortium avoided constructing redundant weather forecasting systems. They engineered a dynamic transboundary cascade matrix tracking a precise timeline: upstream precipitation failure causing immediate river-level declines, leading directly to a mandated transport embargo triggering localized energy shortages and subsequent major civil protests concerning power rationing inside adjacent bordering territories.

The Evaluated Outcome: The macro-regional River Commission officially integrated the system directly into their 2027 Flood Risk Mandate. Evaluators highly prioritized the structure because the coalition specifically utilized trained climate data researchers alongside active civil defense commanders tasked with executing real-world intervention protocols along the established timelines. The project effectively translated vast climatic raw data into uncompromising security intelligence.

6. Strategic Implementation and Consortium Structuring

Executing complex scenario creation requires strict implementation viability spanning 36 intensive months of coordination.

Work Plan Execution

Establish explicit task delineations. Allocate preliminary phases strictly toward advanced climate hazard cascade mapping utilizing defined parameter limits. The central operational timeline must feature intense, co-creation laboratories alongside local public authorities tasked with interpreting the localized scenario narratives. The concluding phase requires widespread dissemination, finalizing open-source replication toolkits, and delivering direct strategic briefings to European regulatory commissions.

Formulating Resilient Consortia

You cannot model transnational infrastructure failures effectively focusing strictly upon a solitary territory. Consortia must encompass an absolute minimum of three sovereign member states. Engaging transboundary mountain partnerships or extensive river commissions validates large-scale operational integrity. Every simulated hazard scenario must inherently terminate upon a critical decision nexus, explicitly documenting exactly what a designated civil protection director must authorize at crucial hour-based vulnerability intersections.

7. The Outlook for Future Scenario Readiness

The funding architecture for civil preparedness continuously aligns with near-real-time synchronization systems and expansive financial safety frameworks. Integrating dynamic, AI-assisted scenario engines capable of digesting and reorganizing live satellite telemetry far outclasses static risk reporting formats. Proposing integration methodologies exploring future alignment with multi-national defense mandates and large-scale, scenario-driven parametric insurance policies proves critical forward-looking sophistication, ensuring evaluators recognize your framework defines the long-term methodology of European disaster resilience.
