Across Europe, adaptation practitioners and decision makers often draw inspiration from existing adaptation solutions by searching the European Union’s knowledge platforms, such as Climate-ADAPT. However, many adaptation solutions already implemented across Europe are not yet represented on the platform.
The REGILIENCE+ project aims to fill in the knowledge gaps of the European adaptation landscape by collecting information on adaptation solutions from recently finished or ongoing European adaptation projects and initiatives, in particular from Mission Projects. Ideally, these solutions will cover a broad range of climate hazards, sectors, adaptation approaches and countries of implementation.
To guide this work, REGILIENCE+ assessed the solutions available on Climate-ADAPT in August 2026, specifically case studies, adaptation options and tools, while also identifying where the most significant gaps remain. These gaps help identify a set of priorities for expanding the European adaptation knowledge base. Below are some of the insights that the assessment revealed.
Country-Level Gaps
Nearly half of European countries are underrepresented across Climate-ADAPT case studies (Figure 1). Several countries currently have no case studies represented on the platform, including Albania, Estonia, Georgia, Kosovo, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Montenegro and Türkiye. Other countries are represented by only one or two case studies (Figure 1). Strengthening geographical coverage will ensure that practitioners can access solutions reflecting a wider diversity of social and economic contexts.
Missing Solutions for Emerging Hazards
Adaptation solutions in Climate-ADAPT (Figures 2 and 3) addressing Wildfires, one of the most pressing and emerging hazards, are barely represented, alongside solutions for low-temperature hazards such as Extreme Cold and Ice and Snow. In contrast, solutions addressing Flooding, Extreme Heat, Droughts and Storms are the most represented. When comparing tools and case studies, Sea-level Rise and Water Scarcity remain less covered. The increase in frequency and intensity of extreme weather events, both cold and heat, reinforces the need to improve the knowledge base of solutions for the underrepresented hazards.
Sectors falling short
Across Climate-ADAPT’s different types of solutions, several sectors are consistently underrepresented, particularly Business and Industry, Financial, Information and Communication Technology (ICT) and Cultural Heritage (Figures 4 and 5); therefore, these are identified as priorities for further development under the REGILIENCE+ list of solutions.
There are also gaps specific to each solution type. Case studies are particularly limited in Marine and Fisheries, and Tourism. Tools are scarce for Tourism, Mountain Areas and Land-use Planning, while adaptation options are least represented in Energy and Land-use Planning.
Replication, Monitoring, and Evaluation Gaps
Considering the adaptation approaches assessed across all three Climate-ADAPT solution types, Just Resilience and Sector Policies stand out as common gaps (Figures 6 and 7). By contrast, approaches focused on Adaptation Measures and Actions, and on Plans and Strategies, are generally better represented.
Case studies, adaptation options and tools also differ in their thematic coverage, partly reflecting their distinct roles within the adaptation cycle. Case studies and adaptation options tend to focus more strongly on the implementation of adaptation measures and therefore show comparatively less coverage of Observations and Scenarios, Climate Services, Vulnerability Assessment, and Monitoring, Reporting and Evaluation. These earlier stages of the adaptation cycle are more commonly supported by tools. Within the tools category, however, relatively limited coverage is observed for Monitoring, Reporting and Evaluation and Nature-based Solutions, which may indicate areas where additional resources could be valuable.
Filling the gaps
REGILIENCE+ goes beyond compiling a list of adaptation solutions: it helps identify where knowledge is already plentiful and where important gaps remain. By highlighting these gaps, the project aims to build a more comprehensive European adaptation knowledge base that better supports practitioners and decision-makers in planning and implementing climate adaptation measures.
