Nature‐based Solutions to Climate Change Adaptation in Urban Areas

The document provides a comprehensive analysis of nature-based solutions (NBS) as a means to address urban climate challenges. It evaluates the efficacy of various NBS—such as urban wetlands, green roofs, and sustainable urban drainage systems (SUDS)—in regulating temperature, managing stormwater, and improving air quality. Beyond environmental benefits, the report examines the positive impacts of urban green spaces on public health and social cohesion, while critically addressing issues of environmental justice and the risk of 'green gentrification'. It also explores the governance and financial barriers to NBS implementation, proposing a 'mainstreaming' framework to integrate these solutions into municipal planning and policy.

• Nature-based solutions (NBS) are conceptualized as an umbrella term that incorporates urban green infrastructure (UGI), ecosystem-based adaptation (EbA), and ecosystem services (ESS), with a specific emphasis on the deployment of actions on the ground.
• Urban parks typically provide a cooling effect of approximately 1 °C during the day, and larger parks or those with more trees tend to have a more significant impact.
• Green walls can significantly reduce temperatures in hot and dry climates, with some instances showing a reduction of nearly 10 °C in street canyon temperatures during the day.
• Sustainable urban drainage systems (SUDS) are often more cost-effective than traditional piped drainage, with some estimates showing cost savings between 10% and 85%.
• Regulating ecosystem services, such as carbon sequestration and air purification, often have a marginal impact at the city or metropolitan scale, but can be highly effective at the site scale, such as in street canyons or around specific green spaces.
• Urban green spaces provide significant mental health benefits, including reduced levels of depression, anxiety, and stress, and are particularly beneficial for disadvantaged groups.
• The implementation of NBS can lead to 'green gentrification' or 'eco-gentrification', where environmental improvements increase real estate prices and result in the displacement of lower-income residents.
• Urban gardens, including allotments and community gardens, serve as multifunctional NBS that provide food security, support biodiversity, and foster social cohesion and resilience.
• Effective adaptation mainstreaming requires a combination of four local risk-reducing approaches: reducing exposure, reducing vulnerability, preparing an effective response, and preparing an effective recovery.
• Municipalities often face financial barriers to NBS because their revenues are frequently tied to specific mandatory tasks, leaving little discretionary funding for 'self-determined' functions like urban greening.
• Hybrid approaches that combine 'grey' engineered infrastructure with 'green' and 'blue' NBS are often the most effective strategy for disaster risk reduction in dense urban contexts.
• In Poland, the diffusion of NBS is hindered by a preference for 'hard' infrastructure and a lack of strong institutional controllers to enforce greening regulations.
