URBAN PLANNING IMPACT ON OUTDOOR THERMAL COMFORT USING REMOTE SENSING TECHNIQUES IN QATAR

Abstract

Rapid urbanization has resulted in an unprecedented global rise in land surface temperatures (LST). Local climates and ecological systems are substantially altered by transforming natural landscapes into impervious surfaces, which is a significant factor in this transition. Due to their high thermal conductivity, impervious surfaces exacerbate surface energy imbalances, leading to an increase in LST and outdoor thermal discomfort, which negatively impacts both physical and mental health. This research examines the relationship between urban land cover changes and their impact on seasonal LST variations, particularly in arid regions such as Qatar, where conventional urban planning methods may be ineffective. The research utilized Geographic Information System (GIS) tools and remote sensing techniques to collect and analyze data. The findings reveal that conventional urban greening strategies may not be appropriate for arid climates, as non-native vegetation could exacerbate resource depletion without significantly improving LST or improving outdoor thermal comfort. The existing policies in Qatar addressing urban heat adaptation are reviewed, identifying gaps and opportunities for improvement. The results have significant implications for the sustainability of outdoor environments, urban planning, and climate adaptation in swiftly expanding developing countries, particularly in the Middle East, further contributing to the development of climate change mitigation strategies in arid regions.
