The urban fringes are experiencing a significant surge in surface temperature during the transition from rural to urban, inducing imperceptible disturbances. The present study analyses the temperature modulations from 2000 to 2022 in Kalarahanga and Raghunath­purjali fringes in North Bhubaneswar to understand the relationship between spatiotemporal changes and land-surface temperature in the fringes. The investigations reveal a consistent decrease in the area under water bodies and crops, with an increase in the built-up area. Besides, there exists an inverse correlation between the area under high and medium temperature with the area under cropland (–0.820) and the area under water bodies (–0.799), and a positive correlation coefficient (0.813) with the built-up area/impervious surfaces. This insists on eco-sensitive planning of the urban fringes with consistent monitoring of land use and thermal dynamics for apt control of the changes in the urban microclimate.

Abstract


The urban fringes are experiencing a significant surge in surface temperature during the transition from rural to urban, inducing imperceptible disturbances. The present study analyses the temperature modulations from 2000 to 2022 in Kalarahanga and Raghunath­purjali fringes in North Bhubaneswar to understand the relationship between spatiotemporal changes and land-surface temperature in the fringes. The investigations reveal a consistent decrease in the area under water bodies and crops, with an increase in the built-up area. Besides, there exists an inverse correlation between the area under high and medium temperature with the area under cropland (–0.820) and the area under water bodies (–0.799), and a positive correlation coefficient (0.813) with the built-up area/impervious surfaces. This insists on eco-sensitive planning of the urban fringes with consistent monitoring of land use and thermal dynamics for apt control of the changes in the urban microclimate.
