Despite accelerated rates of coastal erosion and growing coastal populations, global understanding of the relative resilience of communities to coastal erosion is limited yet social justice and climate justice are key emerging issues of concern for governments. For the first time in the UK, using Scotland as an exemplar, this work aims to couple anticipated erosion risk with consideration of the social vulnerability of Scotland’s coastal communities, to produce Coastal Erosion Disadvantage maps. A combination of Dynamic Coast erosion data, the latest Census data from 2011, the latest data from the Scottish Index of Multiple Deprivation (2016 & 2020) and academic and policy literature concerning coastal erosion and flooding vulnerability, were used to create a Social Vulnerability Classification Index (SVCI) using a series of deprivation and context-specific indicators. We report that coastal communities have a slightly higher proportion of more socially vulnerable groups compared with the Scottish average with spatial variations in Coastal Erosion Disadvantage (e.g. East Lothian, South Ayrshire and Argyll & Bute have higher vulnerability). The maps show that under an IPCC “High Emissions Scenario” (HES RCP8.5), and assuming no future maintenance of coastal defences, 37% of the residential property anticipated to be affected by coastal erosion are within the top three SCVI vulnerability categories. In addition, 67% percent of socially vulnerable properties that are anticipated to be at coastal erosion risk by 2050, are currently undefended. We recommend that this initial assessment is used by planners as a catalyst of further in-depth place-based assessments of social vulnerability to erosion for current and future planned developments in at risk communities, to help society become ‘sea level wise’.
