Abstract
Background and Objective: With the rapid pace of urbanization and its associated environmental challenges, novel approaches such as the smart sustainable city and green infrastructure have become essential. However, the gap between theory and practice, particularly regarding the prioritization of interventions, persists. This study was conducted with the objective of analyzing the impact of green infrastructure on the realization of a smart sustainable city and providing a data-driven framework for spatial prioritization in the metropolis of Karaj.
Methodology: This is an applied study employing a descriptive-analytical method. Initially, 24 key variables were identified and distributed to 30 experts via a questionnaire. Subsequently, using a hybrid approach, the Cross-Impact Matrix Multiplication Applied to Classification (MICMAC) technique was utilized to identify key drivers, and the Combined Compromise Solution (CoCoSo) method was employed to rank the readiness of the 11 urban districts of Karaj.
Results and Findings: The results indicated that seven drivers, including "permeable surfaces," "ecological corridors," "investment," and "integrated governance," are the most powerful factors influencing the system. Furthermore, the CoCoSo analysis identified District 5 as the most suitable area for initiating projects. The findings emphasize that a successful transition to a smart sustainable city requires an integrated strategy that simultaneously focuses on physical infrastructure, governance factors, and economic incentives, and that policies must be formulated based on spatial priorities. Ultimately, this study shows that the realization of a smart sustainable city in Karaj is only possible through an integrated strategy that incorporates the key physical, governance, and economic drivers within specific spatial priorities.
