Abstract :The identification of locations for both municipal solid waste (MSW) landfill and construction and demolition waste (CDW) disposal necessitates a comprehensive spatial planning strategy, particularly in environmentally sensitive and physically constrained areas. Gökçeada, an island characterized by limited developable land and seasonal population variations due to tourism, requires integrated planning for MSW and CDW. This research utilized a multi-criteria decision-making model (MCDM) that integrates the Analytic Hierarchy Process (AHP) with Geographic Information Systems (GIS) to determine appropriate sites for both forms of waste. The findings indicate that merely 3.61% of the island is appropriate for municipal solid waste landfill and 3.67% for CDW disposal site, with extremely favorable regions accounting for 1.04% and 0.61%, respectively. 3 locations; Area 1, Area 2, and Area 3 were recognized as feasible choices, each presenting unique spatial and logistical benefits. Moreover, the designated locations align with the anticipated MSW accumulation volume by 2058. This dual evaluation facilitates optimal land utilization, mitigates environmental repercussions, and offers a reproducible framework for sustainable waste management in island regions.
