Top 3 runners
The 2024 Grand Marathon invited innovators using Earth Observation data to tackle climate change and public health challenges, with a particular focus on solutions benefiting children and adolescents. The winning solutions will collaborate with Save the Children to explore opportunities for implementing them in future initiatives.
1) EpiWise by GEOMATYS: climate-sensitive epidemic disease prediction maps and population risk characterisation, integrating real-time Earth Observation data.
2) PLASTIC-I: real-time intelligence on plastic pollution and its associated health risks, combining Earth Observation and AI.
3) AirCare by GRASP: monitoring and analysis of PM0.1 and PM2.5 levels, to improve air quality management, optimise emissions and support health initiatives.
