Investigation of cities’ spatiotemporal dynamics, including vegetation and urban areas, is of utmost importance for understanding ecological balance, urban planning, and sustainable development. This study investigated the dynamic interactions between vegetation, settlement patterns, and surface urban heat islands (SUHIs) in Istanbul using spatiotemporal hotspot analysis. Utilizing Landsat satellite imagery, we applied the Getis-Ord Gi* statistic to analyze Land Surface Temperature (LST), Urban Index (UI), and Normalized Difference Vegetation Index (NDVI) across the city. Using satellite images and the Getis-Ord Gi* statistic, this research investigated how vegetation and urbanization impact SUHIs. Based on the main results, mean NDVI, UI, and LST values for 2009 and 2017 were analyzed, revealing significant vegetation loss in 37 of Istanbul’s 39 districts, with substantial urbanization, especially in the north, due to new infrastructure development. On the other hand, hotspot analysis was conducted on normalized NDVI, UI, and LST images by analyzing 977 neighborhoods. Results showed a significant transformation of green areas to non-significant classes in NDVI, high urbanization in UI, and the formation of new hot areas in LST. SUHIs were found to cluster in areas with increasing residential and industrial activities, highlighting the role of urban development on SUHI formation. This research can be applied to any region since it offers crucial perspectives for decision-makers and urban planners aiming to mitigate SUHI effects through targeted greening strategies and sustainable urban development. By integrating environmental metrics into urban planning, this study underscores the need for comprehensive and sustainable approaches to enhance urban resilience, reduce environmental impact, and improve livability in Istanbul.

Climate change has emerged as a major challenge affecting urban sustainability. Increased population mobility due to social and economic factors has led to an expansion in urban density. This growth in urban space has resulted in the transformation of physical spaces into built environments lacking green areas. In the microclimate zones formed in dense urban areas, temperatures different from the current situation and thermal values that prevent the comfort level are observed. One of the most basic solutions that can prevent this temperature stress is the creation of recreational areas. In this study, the regulating effect of urban green spaces on microclimate is evaluated as a design element in urban planning. In this context, a study approach is proposed to develop climate-sensitive spatial design strategies. Micro-regions in the city center of Kırklareli are identified and comparative evaluations are made with recreation areas. The study aims to make two main contributions: (1) basic climatic conditions and problems are identified at the city and neighborhood scale, and (2) climate-sensitive spatial design strategies and recommendations are developed in urban and recreational themes.
