Climate adaptation involves strategies and actions aimed at reducing vulnerability to the impacts of climate change and building resilience in communities and ecosystems. In this field, we examine how urban vegetation can contribute to building resilience to extreme weather, such as extreme heat, within cities, particularly in vulnerable communities. We explore the lived experiences of these communities with heat and other climate pressures, and investigate the effectiveness of urban vegetation in supporting adaptation across various scales and built environments, with the goal of creating more liveable and equitable urban environments.
