Developing indicators for sustainable urban regeneration in historic urban areas: Delphi method and Analytic Hierarchy Process (AHP)

Abstract

This paper presents a comprehensive evaluation model comprising indicators spanning four dimensions: social, economic, environmental, and governance. Extensive indicators were gathered from the literature and subsequently subjected to a rigorous screening, validation, and finalization process by a panel of 25 international experts through a Delphi survey. The relative weights assigned to each indicator were determined utilizing the Analytic Hierarchy Process (AHP). The findings reveal that the social dimension carries the greatest significance in achieving sustainable urban renewal (SUR), closely followed by the environmental dimension. In terms of assessment categories, the highest priority and weight (0.1186) were attributed to "building and land use," while "economic viability" (weight=0.1049), "policymaking" (weight=0.0982), "community involvement" (weight=0.0882), and "housing provision" (weight=0.850) were also identified as significant areas. The paper emphasizes that these proposed indicators can serve as valuable tools to inform the review and enhancement of urban planning guidelines and policies at the local, state, and national levels, fostering sustainable urban regeneration.
