In Europe, cities are confronting the challenge of adapting existing urban conditions to a changing climate and warming summers while improving access to nature, quality public spaces, and the resources of everyday routines. ReGreeneration, a Horizon Europe initiative working across nine European cities, approaches this challenge through urban renaturing at the neighborhood scale. Combining strategies for complete neighborhoods, communal spaces, and nature-based solutions for cities, the Barcelona project examines how climate adaptation is embedded within residual, peripheral spaces of daily life. As part of a series following ReGreeneration across the participating cities, this article turns to Barcelona, where the project is working in the Trinitat Nova neighborhood to explore how small, often overlooked, urban spaces contribute to broader models of regeneration.
