Access to actionable information that outlines opportunities for nature-based solutions (NBS) investments at early stages of project design is essential for enabling the scale up of these solutions, which can effectively reduce climate risks, while bringing important socioeconomic benefits. This report summarizes how the Nature-Based Solutions Opportunity Scan (NBSOS) supports the World Bank, its clients, and development partners to identify NBS investment opportunities, understand the associated benefits, and integrate these interventions into projects. The NBSOS is a geospatial analysis and participatory process that provides an on-demand service tailored to each specific case in both cities and coastal areas, ensuring World Bank project teams have a clear understanding of available NBS investment opportunities in a given project area.
