Citizen Science is a rapidly expanding and diversifying field of innovation with significant implications for, and potential benefits to, society, policy, and various academic research areas. This heterogeneity leads currently to a fragmented and not fully coordinated European Citizen Science landscape. 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 breakthrough will be pursued through three interconnected lines of activity: (i) coordination of citizen science actions and leveraging of existing resources in the presently fragmented landscape of Citizen Science in Europe, (ii) engagement of quadruple helix stakeholders at all levels (local, national and European), and (iii) creation of a mutual learning space and a set of comprehensive co-designed training modules for the different target audiences. Moreover, following a transparent, open and inclusive approach, EU-Citizen.Science will promote interdisciplinary, cross-border, cross-sector collaboration, and give rise to significant social innovation and new business models through the creation of new partnerships and the provision of novel sustainability-supporting tools. The EU.Citizen.Science project involves 14 partners and 9 third parties, representing 14 European Member States and a variety of stakeholders ranging from universities, NGOs, local authorities, CSOs and natural history museums, along with several other project supporters. Many of the partners are already engaged in other SwafS projects related to RRI, co-creation and citizen science, as well as numerous initiatives at national or local level.

THE MICS project brings together a transdisciplinary team to address a scientific and policy priority area where citizen science has the potential to promote a paradigm shift. Nature-based solutions (NBSs) are actions to protect, sustainably manage and restore natural or modified ecosystems that address societal challenges and provide human well-being. NBSs have increasingly become policy and planning objectives, but major knowledge gaps in NBSs science have hindered their implementation and acceptance. This is largely due to a lack of locally specific information about the influence of: climate, location, condition and management on NBS function and impact. Furthermore, the sustainability of NBSs often depends on the perceptions and needs of stakeholders, including user groups, local communities, conservation bodies, farmers, land managers, policy makers and practitioners. Due to their systemic complexity and embedding in local context, NBSs offer a unique potential for citizen science to make a major contribution. The MICS project will support NBS research by developing strategies and tools to evaluate impacts on science and society resulting from the integration of citizen science. These tools will foster citizen science approaches that increase both scientific knowledge, and how scientific evidence is taken up by communities and policy makers. MICS will use novel impact-assessment metrics and instruments that measure costs and benefits of citizen science in relation to the NBSs, with particular attention in the domains of society; democracy; the economy; NBS science, and citizen scientists. These instruments will be grounded in a comprehensive conceptual framework and integrated into an open platform following rigorous validation in key pilot sites along a West-East EU axis. This will test the applicability of the MICS impact-assessment tools in regions with differing opportunities and constraints for NBSs, and with different levels of citizen science uptake.

MONOCLE innovates and develops sensor, platform, and data handling technologies to increase coverage and lower the cost of in situ sensors in inland and coastal water bodies. These ecosystems are particularly vulnerable to direct anthropogenic impacts but of high economic importance and crucial to sustainable food, energy, and clean water supply. At the same time, these water bodies represent areas of the weakest performance in present EO capability to date. The MONOCLE system will reduce uncertainties in Earth Observation (EO) by characterising atmospheric and water optical properties. MONOCLE will deploy new and improved sensors on autonomous platforms (buoys, ships, drones), and further fill information gaps by developing low-cost complementary solutions for citizen scientists. This will provide essential reference observations needed to further improve and grow EO-based water quality services. MONOCLE will be requirement-driven and implemented by sensor and platform developers, sensor-data infrastruct

ILIAD builds on the assets resulting from two decades of investments in policies and infrastructures for the blue economy and aims at establishing an interoperable, data-intensive, and cost-effective Digital Twin of the Ocean (DTO). It capitalizes on the explosion of new data provided by many different earth sources, advanced computing infrastructures (cloud computing, HPC, Internet of Things, Big Data, social networking, and more) in an inclusive, virtual/augmented, and engaging fashion to address all Earth Data challenges. It will contribute towards a sustainable ocean economy as defined by the Centre for the Fourth Industrial Revolution and the Ocean, a hub for global, multistakeholder co-operation. The ILIAD DTO will fuse a large volume of diverse data, in a semantically rich and data agnostic approach to enable simultaneous communication with real world systems and models. Ontologies and a standard style-layered descriptor will facilitate semantic information and intuitive discovery of underlying information and knowledge to provide a seamless experience. The combination of geovisualisation, immersive visualization and virtual or augmented reality allows users to explore, synthesize, present, and analyze the underlying geospatial data in an interactive manner. The enabling technology of the ILIAD DTO will contribute to the implementation of the EU?s Green Deal and Digital Strategy and to the achievement of the UN Ocean Decade's outcomes and Sustainable Development Goals. To realize its potential, ILIAD DTO will follow the System of Systems approach, integrating all existing EU Earth Observing and Modelling Digital Infrastructures and Facilities To promote additional applications through ILIAD DTO, the partners will create the ILIAD Marketplace. Like an app store, providers will use the ILIAD Marketplace to distribute apps, plug-ins, interfaces, raw data, citizen science data, synthesized information, and value-adding services derived from the ILIAD DTO.

In the past decade, citizen science has become a proven and accepted methodology across a wide range of scientific disciplines, able to collect new and complementary data which both enhances and adds context to existing data collection methods. By upscaling to a transnational level, citizen science could collect, analyse and exploit a vast amount of data across the ERA and beyond, achieving a higher impact through creating a multinational community of citizen scientists. However, many citizen science initiatives start at a small-scale, facing technical, practical and conceptual changes when attempting to upscale to a wider level, with current EU mechanisms and other networks not providing the support, coordination or resources required to assist their effort. CROPS aspires to inform and evolve the EU Research & Innovation system so that it can adequately support the transition of citizen science from small-scale to a Europe-wide level, moving it towards a modern, open-science approach. It will identify the most suitable citizen science initiatives for upscaling to the Europe-wide level, and in doing so will develop protocols, resources and examples of best practice for the upscaling of citizen science activities, helping practitioners to fully realise the potential impact of their activities towards the Horizon Europe EU Missions. This support will be tailored to all different types of citizen science, and the different stakeholders that are involved and participation taken.
