Multiscale scenarios for nature futures Targets for human development are increasingly connected with targets for nature, however, existing scenarios do not explicitly address this relationship. Here, we outline a strategy to generate scenarios centred on our relationship with nature to inform decision-making at multiple scales.

Achieving the policy and practice shifts needed to secure ecosystem services is hampered by the inherent complexities of ecosystem services and their management. Methods for the participatory production and exchange of knowledge offer an avenue to navigate this complexity together with the beneficiaries and managers of ecosystem services. We develop and apply a knowledge coproduction approach based on social-ecological systems research and assess its utility in generating shared knowledge and action for ecosystem services. The approach was piloted in South Africa across four case studies aimed at reducing the risk of disasters associated with floods, wildfires, storm waves, and droughts. Different configurations of stakeholders (knowledge brokers, assessment teams, implementers, and bridging agents) were involved in collaboratively designing each study, generating and exchanging knowledge, and planning for implementation. The approach proved useful in the development of shared knowledge on the sizable contribution of ecosystem services to disaster risk reduction. This knowledge was used by stakeholders to design and implement several actions to enhance ecosystem services, including new investments in ecosystem restoration, institutional changes in the private and public sector, and innovative partnerships of science, practice, and policy. By bringing together multiple disciplines, sectors, and stakeholders to jointly produce the knowledge needed to understand and manage a complex system, knowledge coproduction approaches offer an effective avenue for the improved integration of ecosystem services into decision making.natural hazards | regulating services | resilience | participatory research | boundary work

Scenario development has been recognized as a potential method to explore future change and stimulate a reflective process that can contribute to more informed decision-making. The assessment process under IPBES (the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) has however shown that the current predominantly biophysical and economic models and scenario processes for exploring the future of biodiversity, ecosystem services and their contributions to human wellbeing are insufficient to capture the complexity and context-specific nature of the problems facing these sectors. Several important challenges have been identified that require a more in-depth analysis of where more imaginative scenario efforts can be undertaken to address this gap. In this paper, we identify six key characteristics necessary for scenario processes: adaptability across diverse contexts, inclusion of diverse knowledge and value systems, legitimate stakeholder engagement that foregrounds the role of power and politics, an ability to grapple with uncertainty, individual and collective thinking mechanisms and relevance to policy making. We compared four cases of imaginative, arts-based scenario processes that each offer aspects of meeting these criteria. These approaches emphasise the importance of engaging the imagination of those involved in a process and harnessing it as a tool for identifying and conceptualising more transformative future trajectories. Drawing on the existing literature, we argue that there is value in fostering more inclusive and creative participatory processes that acknowledge the importance of understanding multiple value systems and relationships in order to reimagine a more inclusive and just future. Based on this, we reflect on future research to understand the transformative role that imagination can play in altering and enhancing knowledge-making for global assessments, including IPBES. We conclude that creative scenario co-development processes that promote imagination and create an opening for more empathetic responses should be considered as complementary tools within the suite of methodologies used for future IPBES scenario development.
