摘要

Understanding social resilience can assist in the formulation of disaster management policies to help com-munities better prepare for,respond to,and recover from disasters.However,direct social resilience measurement methods such as household surveys are not always a practical option as they are a time-and resource-exhaustive process.Existing measures mainly utilize publicly avail-able census data,which often provide a poor and outdated assessment of current social resilience status.Another limitation includes a failure to capture multiple facets of indicators that are process-oriented and dynamic in nature such as mobility of people.These challenges can be addressed by employing a surrogate approach.Surrogates are alternative measures to depict the target indicator.The surrogate approach can capture key facets of a target indicator,which can be used as potential measures for the target indicator.A framework to conceptualize the surro-gate approach is presented,and operationalized using a case study approach on the southeastern coast of Sri Lanka to identify surrogates to measure mobility of people as a resilience indicator.Six higher-order themes were identi-fied as potential surrogates to measure mobility of people in a disaster context.The approach proposed to methodi-cally identify potential surrogates and their measurement protocols can help to improve the current knowledge base and understanding of complex interrelationships of social resilience.
