Climate change resilience in South-European regions: data, services, indicators and gaps

Global warming, which has accelerated significantly since 1970, is driving rapid and observable climate change (IPCC AR6 2023). Southern European countries, particularly those in the Mediterranean region, are disproportionately affected due to their already hot and dry summer climates, making them highly vulnerable to rising temperatures and altered precipitation patterns. Climate change exacerbate the situation, leading to more frequent extreme weather events and critical challenges such as heatwaves, droughts, and both fluvial and pluvial flooding.

In the ClimEmpower project[1] [2], funded under the Horizon Europe program, five South-European regions characterized by high climate risk and low adaptive capacity were studied to strengthen climate resilience. To empower these regions, a comprehensive analysis of climate-related data, services, and resilience indicators was conducted and regional partners involved to understand their specific needs and primary climate-related challenges, and to identify critical gaps along with methodologies to address them. A key focus of this inter- and transdisciplinary approach was the development and study of resilience indicators, which are essential for assessing the current state of resilience in these regions and for monitoring progress towards improved resilience over time.

This paper presents key findings from the comprehensive analysis of existing datasets and services related to climate hazards, impacts, exposure, and vulnerabilities, as well as gaps identified through collaboration with regional stakeholders. Additionally, an overview of climate change resilience indicators is provided which is based on an extensive analysis of approximately 500 indicators across climate, socio-economic, and governance domains. The analysis reveals an uneven distribution of indicators across different sectors, with a predominant focus on environmental, economic, and governance topics, while critical areas such as water and waste management, food security, and urban planning are notably underrepresented. Significant gaps between available data and indicators for representing region-specific needs were identified, highlighting the importance of prioritizing indicators that are meaningful and actionable for localized adaptation efforts.

Concluding, the study demonstrates that not all indicators hold equal relevance across all regions and quality, and relevance should be prioritized over the sheer quantity of indicators. Thus, the emphasis should be placed on indicators with high significance and ability to support the development of region-specific pathways to enhance climate resilience in vulnerable South-European regions, ensuring that resources are directed toward the most critical areas of need.
