Nature-based solutions for climate-resilient cities

Can your city weather a changing climate? Cities are challenged to deliver sustainable, resilient infrastructure and services in an increasingly volatile climate.

Key facts

The increased frequency and intensity of extreme weather events drives global climate adaptation efforts. 

Nature-based and integrated blue-green-grey solutions use natural features and ecological processes to address societal challenges. 

VTT creates innovative, customised nature-based solutions to climate- and water-related challenges within an integrated urban ecological framework. 

The increased frequency and intensity of extreme weather events drives global climate adaptation efforts. Urban areas are particularly vulnerable to flooding because water cannot infiltrate the underlying soil where the soil surface is covered by impenetrable materials like roads, parking lots, sidewalks, and buildings. Surface sealing in urban areas increases surface runoff, which in turn increases water pollution, reduces recharge of groundwater resources, and places increased pressure on ageing infrastructures. 

Innovating with nature

The integration of green and blue elements with conventional grey infrastructure provides a cost-effective solution to increased urban climate and water resilience. Local and regional ecosystems provide essential natural capital for climate change adaptation. Nature-based solutions (NbS) re-connect urban areas with the biosphere, improving urban areas’ resilience to climate change through provision of ecosystem services that mediate the impacts of climatic stressors.

Nature-based solutions enhance water and climate resilience by re-connecting cities with the biosphere.

NbS and integrated blue-green-grey solutions (Stormfilter project, CLASS project) use natural features and ecosystem-based processes to address societal challenges such as flooding, environmental pollution, biodiversity decline, and human well-being. A unique aspect of NbS is their ability to simultaneously provide multiple environmental, social and economic co-benefits while building resilience to the impacts of climate change. Some of the more common NbS include multifunctional green spaces, rain gardens and green roofs used to manage stormwater runoff, attenuate urban heat islands and abate pollution.  

Collaborate with us

VTT’s multi-disciplinary experts apply advanced know-how to create innovative NbS and integrated blue-green-grey concepts tailored to specific environments and customer needs. We work with our clients to deliver smart, reliable solutions whilst optimising the multiple potential co-benefits. When it comes to NbS, there is no one-size fits all solution. Let VTT provide the expert guidance needed to successfully design, implement and evaluate the impacts of your unique NbS.
