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.

Une étude a été lancée à la fin du mois de mars 2022 dans trois quartiers de la ville pour mesurer l'effet écologique de l'extinction de l'éclairage nocturne.Rouen Naturellement, le plan de renaturation de la ville, comprend un volet limitation de l’éclairage artificiel : en effet ce dernier entraîne la dégradation et la disparition d’habitats naturels. Afin de restaurer un réseau de corridors écologiques propice à la vie nocturne (on parle de « trame noire »), il est impératif de réduire la pollution lumineuse.

L'éclairage nocturne représente un enjeu économique et écologique auquel la région veut s'attaquer

Recent reports of drastic declines in insect populations have raised global concerns about their conservation. Light pollution is a near inseparable feature of human-altered landscapes and is a potential contributing factor to insect declines.
