Scaling Nature-Based Solutions (NbS): Lessons from Global Progress and Indonesia¡¯s Path to Sustainability
Nature-based Solutions (NbS) have emerged as a transformative approach to addressing climate change, biodiversity loss, and sustainable development. Despite growing global recognition, the implementation of NbS remains uneven, particularly in countries like Indonesia, which possess high ecological potential but face several challenges. This study critically reviewed the global recognition and implementation progress of NbS in achieving international sustainability and climate agendas, with a particular focus on identifying key enabling factors and hindering risks, and deriving globally informed lessons tailored to Indonesia¡¯s context. This study presents a comprehensive systematic review of 219 peer-reviewed articles from the Web of Science (WoS) and Scopus, conducted following the PRISMA 2020 protocol. The review identifies three primary typologies of NbS¡ªIntrinsic, Hybrid, and Artificial¡ªeach associated with specific ecosystem types and functions. It maps their alignment with major global agendas, including the Sustainable Development Goals (SDGs), the Paris Agreement, Nationally Determined Contributions (NDCs), the Sendai Framework, the Nature-Positive 2030 initiative, the Kunming-Montreal Global Biodiversity Framework (GBF), and the Climate Resilient Development Pathway (CRDP). Intrinsic NbS, such as forests, wetlands, and peatlands, dominate the literature due to their critical roles in carbon sequestration, biodiversity conservation, and disaster mitigation. Findings reveal a significant research gap in Indonesia, with only four studies explicitly linking NbS to national climate commitments of the NDC. Key barriers to implementation include fragmented governance, lack of standardized frameworks, limited stakeholder engagement, and insufficient financial mechanisms. Conversely, enabling factors such as regulatory reforms, green financing instruments (e.g., green sukuk, ecological fiscal transfers), and the integration of traditional ecological knowledge (TEK) offer promising pathways for scaling up NbS. This study contributes a novel typological framework and a synthesis of enabling and hindering factors contextualized for Indonesia. It underscores the need for localized, evidence-based NbS strategies that are aligned with global frameworks yet tailored to national socio-ecological realities. By bridging global lessons with local contexts, the findings provide a strategic foundation for policymakers, researchers, and practitioners to enhance the effectiveness, scalability, and equity of NbS in achieving climate resilience and sustainable development.
