This study analyzed the relationship between Local Climate Zones (LCZ), Land Surface Temperature (LST), and water usage in Tehran (2015–2019) to inform urban water management. UWC data was spatially matched to urban areas to calculate per capita consumption. An LCZ map for the base year 2017 was generated using the Random Forest (RF) algorithm, achieving an accuracy of 88.88 %. LST data for the five years was derived using the single-channel algorithm. LCZ2 of dense midrise buildings exhibited the largest area, while LCZG of water had the smallest area. Annual per capita UWC showed a consistent upward trend, with 2019 experiencing the most significant increase. The highest UWC was in LCZG and LCZ2, respectively, while LCZ7 of low dense single buildings recorded the lowest. Most of the city's area had neighbourhoods with an average LST ranging between 30 °C and 35 °C throughout the study period. The correlation between population density, LST, and UWC was 10 % to 17 %. Modelling accuracy, measured by Root Mean Square Error (RMSE), ranged from 1.4 to 9.9. This research highlights the need for climate-sensitive urban design and sustainable water management, providing a foundation for policies to address water scarcity in vulnerable urban areas. Additionally, analyzing annual population dynamics and improving UWC modeling will help better reflect future urban water consumption patterns.</div></div>","PeriodicalId":48659,"journal":{"name":"Sustainable Cities and Society","volume":"127 ","pages":"Article 106438"},"PeriodicalIF":10.5,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This challenge is particularly severe in the global south, where rapid urban expansion leads to the loss of green and blue spaces, essential for temperature mitigation. This study investigates how the spatial configuration of urban blue spaces affects summer temperatures, using remote sensing and field data from a rapidly growing urban agglomeration i.e., English Bazar Urban Agglomeration (EBUA) in Eastern India. The study applied ANOVA and Tukey’s HSD tests to assess temperature differences across urban core, transitional, and rural zones, comparing remote sensing and field data. Bayesian regression analyses further explore relationships between temperature and various explanatory factors, including vegetation and built-up density. Results indicate elevated land surface temperature (LST) in the urban core, reaching a peak of 63.08 °C at 80 m from blue spaces. In the transitional zone, LST shows moderate increases, from 62.21 °C at the blue space edge to 63.06 °C at 100 m. In rural areas, LST starts lower at 60.83 °C, showing minimal variation due to cooling effect of vegetation cover. ANOVA results reveal no significant variation across zones of temperature in remote sensing data (<em>p</em> = 0.144), possibly due to spatial averaging, while field data shows significant differences (<em>p</em> = 0.00045), capturing localized temperature changes. Bayesian regression highlights percentage of vegetation cover, normalized difference water index (NDWI), normalized difference built-up index (NDBI), and area of blue space as key LST predictors, with an R² of 0.875. The findings of the study on the investigation the impact of the spatial configuration of blue spaces on temperature mitigation is crucial in order to facilitate sustainable urban planning.

Taking the built-up area of Shenyang, China, as an example, the compactness index containing spatial, functional and socio-economic dimensions and the TC index were first constructed based on multi-source data. Afterwards, different types of compactness-optimized areas, dominant compactness in different regions, and trade-off and synergy patterns among various dimensions of compactness were revealed using a geographically weighted regression model (GWRM) and local bivariate spatial autocorrelation analysis. The results show that compactness decreases from the center to the periphery of the built-up area, while TC follows the opposite trend.
