Abstract
This chapter introduces the aim of the NBS Impact Evaluation Handbook as a
reference for evaluating the impacts of nature-based solutions (NBS). It provides
a general framework on the value of NBS to the community, investors, and policy
makers, and illustrates how the NBS impact evaluation framework can be used.
Chapter 1 describes the global context in which NBS operate. Two infographics
help visualise the definition of NBS and provide an in-depth explanation of the
concept’s origin and evolution. Another infographic describes the full life cycle of
NBS including monitoring, evaluation, and cost-benefit analysis. The chapter
concludes by describing the content of each section of the handbook.
