Multi-Temporal Analysis of Urban Heat Island Phenomenon Distribution in the Special Region of Yogyakarta (2018-2022) Using ArcGIS Story Map

Abstract

Abstract Rapid urban development in the Special Region of Yogyakarta over the last 5 years has resulted in significant temperature variations, impacting urban areas. The study, presented through a Story Map, focuses on the Urban Heat Island (UHI) phenomenon, showcasing temperature changes from 2018 to 2022. Despite a general decline of around 1°C during this period, the year 2022 witnessed a notable 4°C increase in urban temperatures. The dynamics of urbanization, coupled with land use alterations, contribute to the fluctuating surface temperatures. The Story Map serves as a comprehensive medium, incorporating multimedia elements to effectively communicate these variations, the contributing factors, and potential mitigation strategies. The Special Region of Yogyakarta’s urbanization has led to a transformation of its design into a metropolitan area, resulting in increased land conversion and demand for residential purposes. The UHI phenomenon is influenced by factors such as changes in land use, building materials, and human activities. The narrative map provides detailed insights into the temperature changes, emphasizing the significance of addressing UHI in regional and spatial planning. It highlights practical measures like tree planting initiatives and sustainable development planning to mitigate the impact of elevated temperatures. The Story Map, designed to be accessible to a broad audience, serves as a valuable reference for government and planning agencies, encouraging informed decision-making to address the challenges associated with urban climate phenomena in the Special Region of Yogyakarta.
