The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) released their Methodological Assessment of Scenarios and Models of Biodiversity and Ecosystem Services, for which CORU Leader William Cheung was a coordinating lead author, as well as a contributing author for Chapter 5 “Modelling consequences of change in biodiversity for nature’s benefits to people” (p 200-243). The chapter describes the current state of ecosystem service models and modelling approaches for IPBES assessments and other users, and highlights strengths and weaknesses of different approaches to modelling ecosystem services in the context of policy and decision-making.
