In line with its mandate, the IPBES task force on scenarios and models developed a methodological guidance to accompany the foundations of the Nature Futures Framework, a flexible tool to support the development of scenarios and models of desirable futures for people, nature and Mother Earth, welcomed by the IPBES Plenary in decision IPBES-9/1. The methodological guidance was further refined by the task force, and reviewed by the Multidisciplinary Expert Panel and the Bureau in May 2023. The current version was presented at IPBES 10 in document IPBES/10/INF/13 in August 2023. The methodological guidance document consists of two parts: Part I: The Foundations of the Nature Futures Framework, a flexible tool to support the development of scenarios and models of desirable futures for people, nature and Mother Earth, describing the rationale for, and concepts captured in, the Nature Futures Framework; and Part II: A living methodological guidance that introduces the various methods with which the Nature Futures Framework can be used, and points to examples and additional resources for readers who wish to explore further technical details.
