Nature-based solutions (NbS) in mitigating urban warming: evidence from a highly urbanised city

Urban warming is becoming a critical issue for many major cities, with particularly severe impacts in the Global South. Ashraf Dewan will present his study that uses Earth observation and microclimate data to demonstrate the effectiveness of nature-based solutions in mitigating urban heat. Seasonal and annual datasets were collected and analyzed using both spatial and statistical methods.

The findings indicate that rooftop gardens are especially effective at reducing temperatures during the winter and monsoon seasons in rapidly urbanizing cities. However, their effectiveness significantly declines during the pre-monsoon season – when cooling is most needed. Additionally, correlations between urban planning indicators and surface temperatures reveal that water cover plays a key role in reducing daytime temperatures, while the building cover ratio has a greater influence on nighttime temperatures.
