The GROW Observatory has a vision to support the emergence of a movement of citizens generating, sharing and using information on growing and the land. Whilst there is an overarching vision to address land use and management issues, a key scientific objective is to ground-truth sentinel 1 products using insitu crowdsourced soil moisture data. To do this we have run a series of Missions, defined a model and co-design approach to support citizens to measure land and soil parameters at high spatial resolution over large geographical areas, generating a unique soil and land data repository. This deliverable, reports on mission outcomes around the adoption of sustainable land management practices, land use change, and validation of new land management and cultivation practices. Missions are at-a-scale citizen science activities and mass online social learning programmes, which are designed to engage thousands of growers, scientists, policy makers as well as strengthening connections with citizen associations, NGOs, scientific and academic institutions. We describe the process of development of the methods used for the design approach to Citizen Science activities and Missions, i.e. the GROW Framework, which reflects the ambition to increase public awareness and learning, but also to move beyond this by providing information and to support citizens to be agents of change. We include an in-depth and visual review of activity evidencing GROW missions’ impacts. This includes evaluations and outcomes from the final mission insights workshops sessions carried out with communities and stakeholders. This report comprises five sections: Section 1 Describes the context for GROW, to move beyond state‐of‐the‐art citizen science by scaling up and bridging issues for stakeholders involved. We present the iterative development of the final GROW Framework, and describe the values that sit alongside it. Section 2 presents The Changing Climate Mission. Evaluation methods and results are presented, this includes an overview, new tools developed to support citizen science evaluation in GROW Places. Evaluation tools and case studies that were co-created with Community Champions to capture feedback and the experiences of participating communities.
