Urban nature-based solutions have the potential to offer cities a range of opportunities to build climate resilience, improve people’s health and wellbeing, foster social cohesion, enhance biodiversity and develop nature-based enterprises that contribute positively to local economies, all while making our cities more beautiful and comfortable to live in. This requires a new way of working to embed nature-based solutions across cities. However, we have found that a key barrier to realising the potential of nature-based solutions in cities is often silo-working. This means that a typical hierarchical structure has people working on one issue or sector without having the opportunity to work with colleagues in other departments or institutions to combine efforts and achieve more. This guide aims to help you with that journey. It is for people working in city governments who want to develop nature-based solutions that deliver multiple benefits for their city. It has been developed by EM|Path with input from five years’ work with 10 cities across Europe, together with academic partners and enterprises who were part of the Horizon 2020-funded Connecting Nature project.
