A site selection model proposal for sustainable urban regeneration: case study of Karşıyaka, İzmir, Turkey

Cities that have become the most crowded living spaces in all over the world are facing numerous problems and challenges such as environmental pollution, heavy traffic, urban dilapidation, lack of facility provision, and economic decline. Urban regeneration, which is an important agenda for both academia and politicians, aims to address these urban problems which are mostly caused by overpopulation. As the urban regeneration is a complex issue that requires to consider numerous components, regeneration initiatives cannot always achieve sustainable urban applications, which are causing new urban and social problems. Previous research have mainly focused on one aspect of urban renewal, in which a comprehensive perspective is lacking by just considering the physical aspects of the regeneration areas while lacking the social aspects and current global issues such as climate change and urban adaptation. A multi-criteria decision-making process for site selection and sustainable regeneration plan would contribute to better regeneration outcomes. Therefore, this study proposes a multi-criteria decision-making process which combines the analytical hierarchy process (AHP) and geographical ınformation system (GIS) at site selection phase of urban regeneration on a case study that includes all the physical and social components of the study area as well as focusing on sustaining ecological, economic, and social features.
