Our night sky is heavily light-polluted which has a far-reaching impact on our ecosystem, changing daily and seasonal timing of a multitude of organisms we share our environment with. At the NIOO-KNAW, we team up with ecologists and chronobiologists all across the Netherlands to restore healthy rhythms for ourselves and in our natural environment.

Nocturnal illumination leads to a permanent disturbance of natural habitats and there is accumulating evidence for – often negative – impact of artificial light in an increasing number of species.
