Increasing Infrastructure Resilience with Nature-based Solutions (NbS): A 12-Step Technical Guidance Document for Project Developers is specifically for public and private project developers in Latin American and the Caribbean, but other audiences may also find it useful. This guidance helps developers consider how to incorporate nature-based solutions into their project planning from its earliest stages, also emphasizing opportunities for stakeholder engagement and adaptive planning and management throughout. It addresses not only engineering aspects of nature-based-solutions initiatives (i.e., technical assessments, design, implementation, and operations and maintenance [O&M]) but also steps related to governance, economic assessment, financial structuring, and permitting.
