Les enjeux autour de la télédétection et la biodiversité

Bio : Jean-Baptiste Féret is a full-time researcher at INRAe. He is based at TETIS joint research unit, in Montpellier, France. Jean-Baptiste’s research focuses the assessment and analysis of vegetation properties using remote sensing techniques, with a particular emphasis on forest biodiversity metrics and vegetation biophysical properties accessible from optical data, for applications in ecology and environmental monitoring, and a bit of agronomy. These methodological developments involve imaging spectroscopy, multispectral images and time series, LiDAR data and various optical data acquired from leaf scale (field spectroscopy, close-range imaging spectroscopy) to satellite platforms.

Description intervention : Forests are essential ecosystems that harbor a vast array of biodiversity, playing crucial roles in ecological balance, carbon sequestration, and providing habitat for numerous species. Accurately mapping forest biodiversity is essential for effective conservation and sustainable management strategies. Remote sensing techniques offer a powerful toolset for assessing and monitoring forest biodiversity at various spatial and temporal scales. This presentation introduces methods for mapping forest biodiversity based on remote sensing technologies. I will discuss the challenges and opportunities associated with remote sensing-based approaches, and highlight case studies and applications demonstrating the utility of remote sensing in mapping floristic composition and traits in temperate and tropical forests. I will conclude by outlining future research directions and potential synergies between remote sensing and field-based biodiversity monitoring efforts to improve our understanding and conservation of forest ecosystems.
