Assessing the Evolution of Research on Mediterranean Coastal Cultural Heritage Under Climate Extremes and Crisis: A Systematic Literature Review (2000–2024)

Mediterranean coastal cultural heritage sites are increasingly threatened by the impacts of climate change, including sea-level rise, coastal erosion, and extreme weather events, which endanger both their physical integrity and their cultural and economic value. Safeguarding these vulnerable cultural assets requires approaches that integrate technological innovation with effective governance and management strategies. This study presents a systematic review of research published between 2000 and 2024, conducted in accordance with PRISMA guidelines to ensure methodological rigor and transparency. Searches were conducted in Scopus, Web of Science, and Google Scholar, limited to English-language studies explicitly addressing coastal cultural heritage in the Mediterranean. A total of 77 studies were analyzed using bibliometric and spatial techniques to examine thematic trends, methodological orientations, and regional patterns. Results reveal a sharp rise in scholarly output after 2014, with Italy, Greece, and Cyprus emerging as dominant contributors. The literature demonstrates a strong emphasis on tangible cultural heritage, particularly archaeological sites and monuments, while cultural landscapes and nature–culture systems receive comparatively limited attention. Methodologically, the field is dominated by digital and technology-driven tools such as GIS, remote sensing, 3D documentation, and climate modelling, with socially grounded and participatory approaches appearing in less than 5% of studies. More than 70% of the reviewed works adopt case study designs, which constrain comparative and generalizable insights. In contrast, a predominance of future-oriented assessments highlights a persistent lack of present-day monitoring and baseline data. Collectively, these findings clarify the paper’s exclusive focus on coastal cultural heritage, underscore the need to broaden geographical coverage, integrate socio-institutional dimensions with environmental diagnostics, and prioritize empirical, present-focused approaches. In this direction, future research will advance an integrated framework for assessing coastal vulnerability at both site-specific and regional scales, supporting proactive and evidence-based conservation planning.
