Nature-based solutions proposed to mitigate urban flooding and heat

Experts and environmental agencies are focusing on urban planning strategies to mitigate the impacts of flooding and extreme heat. A practical guide has been released to promote Nature-Based Solutions (NBS) in urban environments. These strategies utilize vegetation, soil, and water to manage challenges such as runoff and thermal discomfort.

Key technical solutions include rain gardens, which promote soil infiltration, and bio-swales, which slow water flow and retain sediment. Other proposed methods include vegetated basins, ecological corridors, and the integration of orchards and vegetable gardens into urban spaces. The implementation of these measures requires careful consideration of terrain slope, soil type, and existing vegetation to ensure effective drainage and permeability.

Discussions in the field also highlight the intersection of engineering and urban planning in preparing cities for changing climate patterns. Experts emphasize that while flooding can be a natural phenomenon, effective drainage plans and infrastructure are essential to prevent urban inundation caused by heavy precipitation.
