Society is nowadays facing unprecedented challenges for food and water security, ecosystem sustainability and resilience to major natural disasters. In addition, climate change represents an overarching and cross-cutting challenge exacerbating all these challenges. Remote Sensing and Earth Observations are necessary not only to monitor, to report and to model the climate change and to address these great societal challenges, but also to contribute to their solution.
The vision of the Remote Sensing and Natural Resources Modelling group is to conduct and to offer research and innovation of excellence, while contributing to the Luxembourg and European economies, the environment sustainability and the human welfare. This contribution is centred on the combination and exploitation of remote sensing information obtained by multiple and complementary sensors installed on spaceborne and airborne platforms, together with in-situ monitoring. The combination of physical and statistical modelling makes it possible to produce information ranging from local or regional to global scales, with unprecedented accuracy and spatio-temporal resolution.
