Abstract

Urban areas increasingly face climate-related challenges such as extreme heat, flooding, and biodiversity loss, that demand innovative, resilient solutions. Nature-Based Solutions (NBS) have emerged as a transformative approach for adapting urban areas, by integrating natural processes into urban planning process to enhance resilience and sustainability. In this paper, the role of NBS in promoting urban resilience is examined, aligning closely with the United Nations Sustainable Development Goals (SDGs), particularly SDG 11, which is intended to alter cities to become inclusive, safe, resilient, and sustainable. Key NBS strategies—such as green roofs, urban forests, bioswales, permeable pavements, sustainable building materials having high solar reflectivity— offer climate adaptation benefits such as temperature regulation and stormwater management, improved air quality, carbon sequestering, encouragement of biodiversity, and the promotion of social well-being. The implementation of NBS faces however, multiple challenges, including policy, financial, technical, and social barriers. In this paper each of these obstacles are addresses and the need for a paradigm shift is emphasized to overcome such barriers that would involve policy incentives, hybrid solutions, and community-driven strategies. Through a review of case studies, taken from Toronto, Detroit, Singapore, Malmö, and Rotterdam, are used to illustrates how hybrid NBS approaches, in which ecological processes have been combined with traditional engineering, have successfully used to address specific urban challenges. These cases demonstrate the potential of NBS to deliver multifunctional benefits, especially when implemented through cross-sector collaboration and supported by adaptive management frameworks. By providing useful outcomes that can be turned directly into actionable insights for policymakers, urban planners, and stakeholders, the results described in this permit advocating for the integration of NBS as a pathway to sustainable, resilient urban landscapes. Indeed, it is shown that the implementation of NBS enhance urban adaptability and contribute significantly to global sustainability goals, offering scalable models for cities worldwide.
