NODES will mobilize the tools of citizen and data science combined with Earth observations to monitor, analyze, and foster progress towards the UN Sustainable Development Goals (SDGs).
To realize this vision, NODES will exploit novel data ecosystems in which several actors interact via infrastructure, analytics, and applications to produce, analyze, exchange, and consume data.
Three main cross-fertilizing pillars characterize the research focus of NODES:
- Advancing the field of citizen science: NODES will remain at the forefront of citizen science from conceptual advancements to innovations in citizen science practice, including the development of new means to acquire, analyze, and openly share citizen science data, as well as how citizen science can contribute to the SDGs and sustainability.
- Enriching Earth observation: NODES will utilize new types of Earth observation technology (e.g., high-resolution imagery, drones, and the Internet of things (IoT)) and develop applications that focus on the interplay between Earth observation and citizen science using Geo-Wiki tools, various forms of remote sensing, and on-site observation.
- Exploiting the digital revolution: NODES will harness the opportunities arising from the digital revolution by exploiting advancements in computing capabilities, data science (e.g., machine and deep learning), environmental informatics, and the geospatial sciences, among others, to enhance integrated systems science research and generate new and innovative data sets for further insights.

Project "G/ArtenLeben": Turning gardens into biodiversity hotspots together
How can private gardens help support biodiversity in Austria? The new IIASA citizen science project G/ArtenLeben brings science and gardening practice together. At three G/ArtenCafés in Lower Austria, hobby gardeners are invited to contribute their knowledge and experience to research and work alongside scientists to explore how gardening can help biodiversity thrive.

New citizen science campaign on mowing events launching in 2026
Starting this Friday, 31st of July, the Mowing Quest citizen science campaign invites people across Europe to help improve grassland monitoring. By using the free Geo-Quest app, participants can report mowing events directly from the field and support scientific research with their own observations. The campaign will be open during August and September to test the system capabilities in preparation for a larger 2027 campaign.

Tree-Quest: a citizen science tool for collecting single-tree information
Tree-Quest is a citizen science mobile tool that enables users to measure aboveground biomass related attributes (tree diameter, height and species) and estimate carbon stored in trees while contributing data for forest and urban tree mapping, supporting research on biomass and carbon storage. Engaged citizens can measure nearby trees in their local surroundings, such as parks and along the streets in urban areas, integrating science into their daily routines. This helps generate valuable ground-based observations on trees in urban environments that can be used for satellite-based carbon assessment.

Citizen science and the politics of measuring sustainability
How we measure sustainability matters. In a new World View article published in Nature Sustainability, IIASA researcher Dilek Fraisl explores why citizen science and other participatory approaches should play a greater role in developing the indicators and methodologies that guide international action on climate, biodiversity, and sustainable development.

Towards a pan-European research infrastructure for excellent citizen science
Citizen science is changing how research is done, but fragmented platforms and tools continue to limit its potential. Through the Horizon Europe-funded RIECS-Concept project, IIASA is helping to lay the foundations for a pan-European research infrastructure that will connect citizen science efforts across Europe and strengthen their scientific and societal impact.
