Implementation of Equivalence-Based Land Readjustment Model Using a Hybridized Multi-Criteria Decision Analysis

Land readjustment (LR) constitutes the foundation of orderly and sustainable urbanization, serving as the primary implementation tool for development plans. LR implementations are generally addressed within the framework of development implementation models—namely area-based, value-based, and hybrid models—based on the principle of redistribution. The present study aims to implement an equivalence-based LR model in the Davultepe Neighborhood of Mezitli, Mersin. In addition, it compares an equivalence-based LR implementation with an area-based LR implementation. The area-based LR implementation was conducted according to Article 18 of Law No. 3194 within the scope of Turkish Zoning Legislation. The equivalence-based implementation was performed using the hybridized multi-criteria decision analysis methods—specifically, SWARA and WASPAS. Cadastral and zoning criteria were determined separately. For data related to spatial criteria, walking distances were calculated using network analysis in Geographic Information Systems software. The weighting of the criteria was performed using the SWARA method. Cadastral and zoning parcels were treated as alternatives, and the WASPAS weight for each parcel was determined. The results indicate that, although allocated zoning parcel areas were generally smaller than the original cadastral parcel areas, in some cases, they exceeded the cadastral parcel areas due to the allocation of zoning parcels designated for agricultural use.
