La pollution lumineuse : passer de la définition d'un problème à sa prise en compte technique

Abstract : At night-time, artificial light is an essential requirement for certain functions and yet it has an adverse effect on the night, on darkness, or on what is commonly accepted as a shared natural resource. The health, social and environmental costs of this loss of darkness are only very rarely considered, leading to the overestimation of the benefits to be drawn from artificial night-time lighting in terms of heritage enhancement, urban image, social night-life, facilitating movement or security, for example. After looking rapidly at the negative consequences of artificial night-time lighting, we aim to show here, through a practical case study, how interdisciplinary dialogue between the different actors can work and result in all the issues raised by light pollution being taken into account in the renewal or installation of new public lighting. This awareness must encourage the competent authorities to look more globally at the situation in order to bring together the normal consensual functions of public lighting (road safety, the security of property and people, heritage development, night-time urban make-up) and the new requirements to be met by lighting in the context of the fight against light pollution.
