The ‘EU-Citizen.Science Stakeholders, Network & Community Mapping Report’ is Deliverable 2.1 (D2.1) within the Coordination and Support Action (CSA) EU-Citizen.Science. The ambition of EU-Citizen.Science is to build, fill, and promote a sustainable platform and mutual learning space providing different tools, best practice examples and relevant scientific outcomes that are collected, curated, and made accessible to different stakeholders, ranging from interested citizens over scientific institutions up to politicians and public media in order to mainstream citizen science in Europe. This deliverable maps and describes the key actors and interested parties whose support and involvement will ensure the success of the EU-Citizen.Science platform. This is accomplished by systematically reviewing the individuals and organisations who play a key role in citizen science activities in general, who are likely to also become the core users of the EU-Citizen.Science platform in particular. The main objectives of this report are to: - Deepen our understanding of the full range of stakeholders in citizen science, - Identify the key stakeholders for the success of the EU-Citizen.Science platform, as users, contributors, and/or supporters, - Expand our working definition of the relevant stakeholder categories and the relationship they are likely to have to the Platform - Form the foundation for other core tasks and activities within the EU-Citizen.Science project across a range of Work Packages. The primary stakeholder groups that we hereby identify, analyse, map and prioritise are: Academia, The Public, NGOs & CSOs, Industry & SMEs, The Press & Media, Educators, and Policy Makers & Funders.

The living Stakeholder Register documents are available upon request from the wider community, for all to make a contribution to.
