This document aims to guide the design, implementation, and use of studies to value the benefits and costs of Nature-Based Solutions (NBS) for climate resilience projects. Reliable quantification of the costs and benefits of NBS for climate resilience can facilitate further mainstreaming of these interventions by articulating the value proposition of NBS across sectors, improve impact evaluation, and for identifying additional funding and financing for projects.
This report provides an overview of methods and approaches, along with a decision framework to guide the design of NBS cost and benefit assessment. The decision framework presented should enable project developers to come up with a cost-effective approach for quantifying the benefits and costs of NBS that is effective and convincing in the context of climate resilience projects. To illustrate this in practical applications, eight case studies from World Bank projects are also included to better show how different valuation methods are applied in the field.
