Biodiversité

Anthropogenic light is ubiquitous in areas where humans are present and is showing a progressive increase worldwide. This has far-reaching consequences for most species and their ecosystems. The effects of anthropogenic light on natural ecosystems are highly variable and complex. Many species suffer from adverse effects and often respond in a highly specific manner. Ostensibly surveyable effects such as attraction and deterrence become complicated because these can depend on the type of behavior and specific locations. Here, we considered how solutions and new technologies could reduce the adverse effects of anthropogenic light.

Animé par Mathieu Vidard, journaliste à France Inter, ce colloque a permis de présenter les dernières connaissances acquises sur les micropolluants et sur le lien entre les activités menées à terre et la qualité des eaux, continentales et marines. Des pistes et leviers ont aussi été proposés pour accompagner l’action publique et réussir la transition écologique.
