Climate change and the historic environment of Wales: a summary of potential impacts

This report summarizes the potential impact of climate change on the historic environment of Wales and is intended to support the production of a sectoral adaptation plan. The principal areas identified from the report are: (i) areas below the one metre contour, affected by predicted sea-level rise; (ii) coast edge and foreshore; (iii) floodplains and valley bottoms; and (iv) peats. Compiled by experts from the Historic Environment Group (HEG), the report warns that a huge amount of Welsh heritage could be lost unless steps are taken to adapt to climate impacts.

The report indicates that 12,000 archeological sites are vulnerable to flooding, many of which are either near rivers or are situated near the coast and less than 1 meter above sea level. It also warns that the 18,000 sites on Wales’ extensive peat bogs are at risk from increased rates of evaporation and erosion, which can both cause severe damage. It summarizes a 2012 report on a strategic approach for assessing and addressing the potential impact of climate change on the historic environment, produced for HEG by the University of Gloucester and Dyfed Archaeological Trust.
