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.

Strengthening citizen science and sustainability monitoring in Europe

Researchers from the IIASA Novel Data Ecosystems for Sustainability (NODES) Research Group are part of the newly launched RIECS-Concept (Towards A Pan-European Research Infrastructure for Excellent Citizen Science), a project designed to develop a conceptual framework for a pan-European citizen science research infrastructure. The initiative aims to enhance the role of citizen science in data collection, validation, and policy engagement, ensuring long-term sustainability and broader participation in scientific research across Europe.
