The NATURA Global Roadmap for Urban Nature-based Solutions is the most comprehensive effort to date to assess the state of knowledge and practice of nature-based solutionS (NbS) in cities and urbanized regions around the world. As cities face escalating challenges — from climate change and biodiversity loss to public health crises and social inequities — the need for sustainable, resilient solutions has never been more urgent. NbS offers a powerful, adaptable approach, working with nature to tackle these interconnected issues while enhancing urban livability and ecosystem health. Though NbS are not a panacea, cities around the world are embracing them as a key component of sustainability and resilience investments. The Global Roadmap is the first comprehensive global assessment of urban nature-based solutions, built from seven Regional Assessments spanning Africa, Asia, Oceania, MENA, Europe, US-Canada, and Latin America—alongside a Global Synthesis Report and Summary for Policymakers.By bringing together scientific research, expert insights, and real-world case studies, the Roadmap offers clear, actionable guidance for decision-makers at every level.Its structure highlights the diversity of urban contexts while providing a cohesive global perspective to guide effective, equitable, and sustainable NbS investments for the future.The Global Roadmap draws on the expertise of regional leads, multidisciplinary teams, and global practitioners. From literature reviews and case studies to expert workshops and rigorous peer review, the assessment process ensures the final insights are both grounded in evidence and reflective of real-world practices. The result? A vital resource empowering policymakers, urban planners, researchers, and communities to drive forward nature-based solutions that create greener, more resilient cities for generations to come.
