Coastal vulnerability analysis to support strategies for tackling COVID-19 infection

The recent COVID-19 pandemic has constrained world governments to impose measures of restraint and social distancing which also involves coastal areas. One of the most affected activities is tourism due to travel restrictions imposed by precautionary measures. This is also reflected in the recreative use of the coastal strip. Consequently, beaches and coastal stretches of small municipalities can potentially become contagious outbreaks of COVID-19 if adequate control and management measures are not promptly implemented. During the 20th century, several factors, both natural and human induced, caused alterations to coastal processes and consequently to the services they were providing. Coastal environments are very vulnerable and sensitive to change. This raises the need for careful assessment prior to any intervention or strategy involving the coastal system. Several literature studies have been focused both in the past and in recent years on examining the main factors affecting coastal vulnerability highlighting critical issues and shortcomings. The present paper, addressing all critical issues from literature review, illustrates a consistent methodology to support coastal management which combines both physical and socio-economic aspects and provides for the quantification of two different coastal vulnerability indices. The approach adopted has led to a distinction of different coastal peculiarities and a mapping of risk levels providing, in addition, the basis for the implementation of strategies risks related to COVID-19. The methodology proposed can be a useful reference in several areas, in demonstrating its effectiveness it has been applied with respect to a coastal area in southern Italy. •Consistent procedure to assess coastal vulnerability based on some key parameters, both physical and socio-economic.•Combine a geographic information system (GIS) with an analytical hierarchical process (AHP) to develop vulnerability maps.•Collecting parameters to define a complete coastal framework able to manage pandemic risks such as the current COVID-19.
