Editorial: Urban nature-based solutions and green infrastructure as strategies for climate change adaptation

Editorial on the Research Topic Urban nature-based solutions and green infrastructure as strategies for climate change adaptationThe consequences of climate change, such as flooding, urban heat island effects, heat waves, and air pollution, pose serious threats to urban environments, which are exacerbated by the significant increase in impervious surfaces.The European Union (EU) is committed to tackling these impacts and aims to become the world's first climate-neutral continent, in line with the key climate and energy targets launched last decade.Nature-based Solutions (NbS) are designed to use our environmental resources without significantly altering the natural habitat; this not only reduces our carbon footprint but also renders cost-effective solutions.NbS measures are proven to benefit our environment and are likely to increase urban resiliency to climate change.However, as an emerging concept, they need further investigation.This Research Topic focused on urban NbS research (rain gardens and green infrastructure, such as green roofs and green walls) and aimed to welcome a Research Topic of high-quality research outputs on minimizing climate change impacts.The published contributions will allow the scientific community to shed light on the technical solutions to improve urban sustainability and resiliency, with a focus on NbS solutions to mitigate the effects of climate change.Applegate and Tilt published an interesting paper on how the concept of urban resiliency is operationalized across spatial scales.This paper is an important contribution to the Research Topic, as much of the work about green cities falls under the concepts of urban resiliency, Green Infrastructure (GI), and Ecosystem Services (ES).This study seeks to understand the criteria considered for the planning, development, implementation, and maintenance of urban resiliency at the city and international levels.
