Pyrenees La Nuit aims to improve the quality of transboundary ecosystems by protecting and improving a very specific aspect: the natural darkness at night.

The increase in light pollution means the loss of this natural value which is, at the same time, a determining natural factor in the state of biodiversity, ecosystems and people's health.

The final and main result is the development of a strategy for the protection and improvement of the quality of the nocturnal environment that also serves as a reference and roadmap for other enclaves or areas that want to address the same problem.



The general objective of the project is to protect and improve the natural darkness of the Pyrenees, as a quality factor for ecosystems and biodiversity.

The specific objectives are:

  • Understand the effect of alteration of natural darkness on the environment and determine standards and tools for monitoring and evaluation.

  • Transmit and raise awareness about the relevance and cultural and environmental value of the natural conditions of the night.

  • Develop a cross-border strategy that promotes good practices in the use of artificial light for the protection and recognition of the nocturnal environment.

  • In addition to preparatory actions (0) and project management (1), this includes the following
