Abstract
This paper explores the issue of light pollution in Croatia with a focus on its impact on astrophotography. Light
pollution, defined as the alteration of natural light levels at night due to artificial sources, has been increasing globally by 7–
10% annually. Croatian cities, particularly Zagreb, exhibit levels of light pollution comparable to major global metropolises,
severely impacting the quality of astrophotography. The study identifies Croatia’s darkest areas suitable for astrophotography
(e.g., Lika, the islands of Lastovo and Vis, and Vrani Kamen), as well as those with the highest light pollution. It also examines
current legislation and implementation challenges, including concrete violations of the Light Pollution Protection Act. Special
attention is given to the potential of developing astrotourism as a sustainable economic activity. The paper proposes
technological, regulatory, and educational measures to reduce light pollution, such as implementing lighting curfews,
modernizing public lighting, and establishing dark-sky parks. Ultimately, the paper underscores the need for a systematic,
collaborative approach involving the scientific community, local authorities, the tourism sector, and civic initiatives to preserve
the night sky as a valuable natural and cultural resource.
