Light pollution is one of the fastest growing forms of environmental pollution in the world today.
It is the result of excessive, misdirected, or unnecessary artificial lighting, especially at night. Such lighting can disrupt the natural cycles of light and darkness, which are essential for the functioning of living organisms, including humans.
In protected areas such as Krka National Park, preserving the natural cycle of day and night is of particular importance. The night landscape, marked by dark skies and natural light sources such as the moon and stars, is an integral part of the ecosystem. Many animal species move, feed, and reproduce in the dark, so artificial lighting can disrupt their behavior and life cycles.
Although the Park's working hours are adjusted to daylight, and the direct impact of light pollution within its borders is not significant, night time light in surrounding settlements, traffic, and the tourist infrastructure can significantly affect the environment. This is precisely why sustainable spatial management includes the responsible use of lighting, both by the community as a whole and by each individual.
Everyone can contribute to reducing light pollution by making simple changes in their daily behavior, such as:
- Using outdoor lighting only when necessary and avoiding unnecessary lighting of the area,
- Choosing lighting fixtures that are directed towards the ground and do not scatter light into the sky,
- Using warmer-toned, dimmer lighting that is less disruptive to natural processes,
- Turning off lights in rooms that are not being used,
- Encouraging the use of motion sensors and lighting timers,
- Planning lighting in accordance with the principles of energy efficiency and environmental protection, which applies equally to local residents and businesses,
- Respecting, in reference to visitors to the Park, the natural rhythms within it and avoiding using strong light sources in the evening hours in the surrounding areas.
Darkness in nature is not just a lack of light – it is an important ecological resource. By preserving the natural night, we preserve the health of the ecosystem, but also our own experience of space. Sustainable development refers to a balance between safety, functionality, and the preservation of natural features. By using light responsibly, we can all contribute to the protection of the unique night landscape.
