Figure 1.2 | Connecting key concepts in this report. The current coupled human and natural system is insufficiently resilient and does not meet societal goals of equity, well-being and ecosystem health. Meeting the objectives of the Paris Agreement, Sustainable Development Goals and other policy statements requires the system to move to a new and more resilient state. Key concepts used in this report help illuminate our current situation and potential solutions. These key concepts are usefully organised around the concepts of risk, solutions and transformation. Risk can prompt solutions and transformation. Both solutions and transformation seek to reduce some risks but may also generate others. Solutions can enable transformation, and transformation can expand the set of feasible solutions.
