Coastal erosion is one of the gravest natural threats to our shared heritage. Although climate change predictions suggest that things will worsen in the future, the problem is already with us. In Scotland, the SCAPE (Scottish Coastal Archaeology and the Problem of Erosion) Trust and the University of St Andrews have been working with the public for many years. Their latest project, SCHARP, works with the public to update previous surveys and to nominate and undertake practical projects at locally valued sites. The project is increasing public knowledge about how climatic events are altering coastlines and informing management decisions, while providing the public a stake in their coastal heritage.
