Green Cities as Biodiversity Hubs

Global biodiversity decline is dramatic. Urbanization is a global trend that is often driving biodiversity loss. At the same time urban green spaces can maintain high levels of biodiversity. However, for urban Nature-based Solutions to maintain biodiversity they have to be designed and managed with this goal in mind. Furthermore, there are certain risks to biodiversity associated with the urban green infrastructure. These risks merit consideration when urban planning is undertaken. Approaches to green infrastructure planning and design can differ depending on whether it is being integrated into existing cities or into new cities at the planning stage. Social and economic considerations can play an important role in determining whether the Nature-based Solutions projects are sufficiently supported in order to be capable of maintaining biodiversity. The presence of both ecosystem services and disservices can shape public attitude towards the solutions. This is a multi-dimensional question requiring thorough consideration to inform policymakers. Here we conduct a multi-factor analysis and based on it propose recommendations to policymakers and practitioners.
