Light Pollution

      Suomi NPP image of Galicia and Northern PortugalLight pollution, i.e. the detrimental alteration of the natural levels of darkness due to artificial lights, has aroused in recent years a growing interest among the scientific community. Besides the widely known consequences of the increased skyglow for science, in particular for optical astronomy, the misuse of artificial light at night has been shown to have measurable and unwanted effects on global energy consumption, ecosystem dynamics, human and animal health and on the preservation of key aspects of humankind's cultural intangible heritage.

     The rapid pace of development of new lighting technologies based in solid-state devices opens interesting possibilities for light pollution reduction and control, but at the same time poses a non-negligible risk of increasing some of its most negative effects. Addressing this complex issue, which involves light generation, steering and detection, atmospheric propagation and scattering, visual and physiological optics, photochemistry, biological effects of light, public health, and energy, including economy and global change aspects, requires a multidisciplinary cooperation of researchers specialized in each of these fields.
