to evolve, as does understanding of appropriate response options and the actors involved. In addition, norms, values and practices may change in response to changing conditions . Much learning by individuals, communities and organisations is unplanned , as is much current adaptation , which can reduce near-term costs and administrative complexity, but may prove maladaptive . Iterative risk management  and related concepts such as risk governance  describe a planned learning process of ongoing assessment, action and reassessment. Iterative risk management can be as simple as scheduling future updates of assessments and plans, as with the 5-year updates of the global stocktake after 2023 called for in the Paris Agreement, or encompass more elaborate learning processes, such as dynamic adaptive pathways  which include specific near-term actions, specific trends to monitor and specific contingency actions to take depending on the future conditions observed. While often more effective at meeting goals, such planned learning processes may pose implementation and governance challenges
