Climate change threatens coastal archaeology through storm flooding (extreme sea-level: ESL), long-term sea-level rise (SLR) and coastal erosion. Many regions, like the Middle East and North Africa (MENA), lack key baseline evidence. We present initial results from a climate change threat assessment of MENA's coastal heritage using the Maritime Endangered Archaeology inventory: a geospatial database of MENA maritime archaeological sites incorporating a disturbance/ threat assessment. It informs two analyses of past disturbance and future threat: (1) using the integral threat/disturbance assessment, and (2) geospatial extraction of information from external coastal change models. Analysis suggests <5% of documented coastal sites are definitely affected by coastal erosion but up to 34% could also have experienced past flooding, erosion, or storm action. Climate change-related threats will increase over the 21st Century and accelerate post-2050 if carbon emissions remain high. SLR and ESL could impact 14–25% of sites by 2050 and 18–34% by 2100. Over 30% to 40% of sites could be impacted by erosion by 2050 and 2100 respectively. Whilst documentation is ongoing and there remain modeling uncertainties, this approach provides a means to redress the absence of baseline data on climate change threats to coastal cultural heritage in MENA.

Urbanisation, comprising development, land reclamation and population growth along coastal margins, continues to place significant pressure on the maritime cultural heritage (MCH), particularly in the Middle East and North Africa (MENA) region. Thus, there is a growing need for ascertaining the extent of the affected MCH resource and its condition. One such assessment is being undertaken by the Maritime Endangered Archaeology (MarEA) project, which is generating a unique informed database of the maritime resource in the MENA region. Through a regional overview combined with focused assessment on two case studies – Marsa Matruh (Egypt) and Bahrain – this paper demonstrates the threat urbanisation poses and the damage it has inflicted on MCH. The analyses and documentation that MarEA produces via remote sensing, desk-based and field-based assessments, constitutes a valuable resource that, at the very least, exists in digital perpetuity. It establishes a record that can be drawn upon to formulate targeted strategies and initiatives inclusive of the maritime cultural heritage resource. [ABSTRACT FROM AUTHOR]

The Middle East and North Africa have witnessed a surfeit of geospatial data collection projects, resulting in big databases with powerful deductive capacities. Despite the valuable insights and expansive evidentiary record offered by those databases, emphasis on anthropogenic threats to cultural heritage, combined with a limited integration of local perspectives, have raised important questions on the ethical and epistemological dimensions of big data. This paper contextualizes maritime cultural heritage (MCH) in those debates through the lens of the Maritime Endangered Archaeology in the Middle East and North Africa project (MarEA). MarEA is developing a unique for the region database for MCH designed to amalgamate a baseline record emphasizing spatial location, state of preservation, and vulnerability. This record will form a stepping stone toward finer-grained research on MCH and its interdisciplinary intersections. It is also developed as an information resource to facilitate local collaborators in prioritizing site monitoring and developing documentation, management, and mitigation strategies.
