A recent study highlights that industrial areas in Telangana, India, are responsible for nearly 70% of the state's thermal hotspot expansion, with significant increases in heat stress over the past two decades. The mean Urban Heat Index (UHI) in industrial zones doubled from 1.35 in 2003 to 2.7 in 2023, indicating a concerning trend linked to urbanization and industrial development.
- 01The mean Land Surface Temperature (LST) in industrial zones rose from 33.8°C in 2003 to 39.8°C in 2023.
- 02Thermal hotspot areas within industrial zones expanded from 420 sq km in 2003 to 1,120 sq km in 2023.
- 03The study identified the Hyderabad–Medak corridor as the main industrial hotspot, with Warangal showing a significant rise in UHI from 1.2 to 2.4.
- 04Machine-learning models pinpointed industrial land use and built-up density as major contributors to heat variability.
- 05Implementing green buffers around industrial areas could reduce the mean UHI by approximately 0.15 units.

A study published in Scientific Reports reveals that industrial zones in Telangana, India, have experienced a significant increase in heat stress over the past two decades, accounting for nearly 70% of the state's thermal hotspot expansion. The mean Urban Heat Index (UHI) in these areas doubled from 1.35 in 2003 to 2.7 in 2023, while non-industrial regions saw a smaller increase from 1 to 1.82. The research, which utilized satellite data and machine-learning models, highlighted the Hyderabad–Medak corridor as a primary industrial hotspot and noted that Warangal's UHI also doubled during this period. The study found that industrial land use, built-up density, and high near-surface air temperatures were key drivers of heat variability. To mitigate heat stress, the researchers recommend increasing green buffer coverage around industrial areas and adopting reflective roofing materials. Overall, the findings underscore the urgent need for effective urban planning and environmental management in rapidly industrializing regions.
