Spatio-temporal patterns of climate parameter changes in Western Mediterranean basin of Türkiye and implications for urban planning

In today's world, where the effects of climate change can be easily monitored, determining the resilience of cities and regions against climate crisis is a fundamental research area in terms of planning approaches. While producing spatial planning decisions, the effects of climate change should be analyzed in terms of time and integrated into the process. While the research reveals the change of spatial bioclimatic comfort zones according to climate change scenarios, it criticizes the position of planning practice within the framework of planning theory and a comprehensive planning approach. The research is carried out on the scale of the Western Mediterranean basin, one of the hot climate regions of Turkiye. The change between 2020 and 2100 is spatially revealed via the climate change scenarios. SSP 245 and SSP 585 are selected for this purpose. Discomfort Index (DI) and Effective Temperature-Taking Wind Velocity (ETv) techniques were used to classify bioclimatic comfort zones. As a result of the research, while the most common (20%) areas are between 16 and 18 degrees C, the most common temperature range rises to between 25% and 22-24 degrees C, according to SSP 585. According to DI simulations, 43% of the area is comfortable, and 38% is in cold areas. According to SSP 245, in 2100 forecasts, cold areas decrease to 9%, and hot areas that were not previously present occupy 13%. According to SSP 585, on the other hand, cold areas decrease to 2%, while hot areas reach 41%. With a more optimistic approach, the ETv index changes from a character dominated by slightly cool areas (35%) to mild (43%) and comfortable (26%) areas compared to SSP 585. However, some warm (7%) and quite hot (1%) areas do not exist. The increase in hot areas in the country, including coastal settlements with high tourism potential, is striking. While the research reveals the change of spatial bioclimatic comfort zones according to climate change scenarios, it criticizes the position of planning practice within the framework of planning theory and a comprehensive planning approach. Today, the position of spatial planning decisions based on long-term decisions in the country's legislation is discussed in the context of the climate crisis.

Automated summary

Determining the resilience of cities and regions against climate crisis is crucial in today's world. This research examines the change of bioclimatic comfort zones in the Western Mediterranean basin of Turkey, highlighting the need for comprehensive planning approaches that integrate climate change scenarios. The findings show an increase in hot areas and a decrease in cold areas, emphasizing the importance of considering climate change in spatial planning decisions.
