Master Thesis Assessment of Spatial Temporal Variability of Urban Heat Island Effect: a Case Study in the Central Districts of İzmir(01. Izmir Institute of Technology, 2024) Ay, Filiz; Kurt, Deniz Gerçek; 01. Izmir Institute of TechnologyThe rapid increase in urban population leads to changes in land use/land cover (LULC) and environmental problems such as Urban Heat Islands. Temperatures in cities being higher than their rural surroundings is a climatic phenomenon known as Urban Heat Island (UHI). Besides direct measurements of air temperature, Land Surface Temperature (LST) that characterizes Surface Urban Heat Island (SUHI) is widely used to determine the impact of UHI. This study aims to determine the spatial/temporal variability of the SUHI effect in the central districts of İzmir for the years 1990, 2000, 2006, 2012, and 2018. Landsat satellite images were used for LST, Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), Normalized Difference Building Index (NDBI), Urban Index (UI), and albedo, while the CORINE land cover dataset was used for LULC maps. In the study, the relationship between LST and LULC, and spectral indices was analyzed using zonal statistics, correlation, and regression analyses. In 2018, the highest LST values were observed for pastures, industry, commercial areas, transportation units, and mines, respectively. There is a high positive correlation between LST and NDBI, UI, Albedo, and a negative correlation with NDVI, respectively, while there is a moderate positive correlation with NDWI. In the regression model, 60.4% of the variability of the dependent variable is explained by NDBI and NDVI. NDBI (71.3%) and NDVI (7.6%) indices were the most effective factors on SUHI formation. The SUHI effect was more comprehensively evaluated across five different regions adding built-up indices into the variable set. It is concluded that the changes in LST values, together with the built environment indices, are largely influenced by changes in LULC.Master Thesis Climate Neutrality in Local Municipalities' Action Plans: İzmir Case(01. Izmir Institute of Technology, 2024) Cihan, Ayşe Melike; Şenol, Fatma; Şenol, Fatma; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThis thesis investigates the integration of climate neutrality within the action plans of local municipalities, focusing on the relationship between these plans and the actions proposed to achieve climate neutrality in the literature. Addressing the uncertainty surrounding the commitment of local municipalities to climate neutrality and the effectiveness of their actions, the study aims to provide insights for enhancing the efficacy of policies and strategies for climate neutrality at the local level. Through a comprehensive literature review and a case study approach focusing on İzmir Metropolitan Municipality in Turkey, the research develops a checklist for evaluating local action plans, with a particular emphasis on mitigation and adaptation measures. Utilizing this checklist, the study assesses the alignment of the İzmir Sustainable Energy and Climate Action Plan (SECAP) and the Green City Action Plan (GCAP) with climate neutrality principles. The evaluation methodology involves scoring each plan based on the presence or absence of specific actions related to climate neutrality criteria, providing both quantitative findings and qualitative insights into the plans' relationship with climate neutrality actions in the literature. This research contributes to understanding how local municipalities prioritize climate neutrality in their efforts to address climate change and offers recommendations for improving the integration of climate neutrality principles into local policies and action.
