Discover this strategic intelligence note to learn more about the urban heat island phenomenon and discover a range of solutions already available to the city-making stakeholders to make public spaces more liveable
The strategic intelligence note "Urban Heat Islands: How to Make Public Spaces More Livable?" examines the challenges posed by rising temperatures in urban areas and presents innovative solutions to mitigate this phenomenon. With 56% of the global population living in cities and a projected 70% by 2050, urban heat islands are a major concern for public health and urban quality of life.
Urban heat islands, characterized by higher temperatures in urban areas compared to surrounding rural zones, are exacerbated by urbanization, the loss of green spaces, and human activities. This phenomenon, observed since the 19th century, is worsened by factors such as building densification, reduced vegetation, and increased greenhouse gas emissions.
To combat urban heat islands, a range of solutions is being implemented. Green solutions, such as greening public spaces and reintroducing water, naturally cool the ambient air. Cities like Santiago and Singapore are planting thousands of trees to create shaded, refreshing areas. Grey solutions, including permeable pavements and misting systems, provide effective alternatives in constrained urban environments. Finally, soft solutions, such as adapting individual behaviors and reducing motorized transport, complement these approaches.
