The natural resources and cultural heritage of Deçan area are very important for the preservation of the natural environment. These properties include wonderful natural landscapes such as cliffs, forests and rivers, which provide shelter for a wide range of fauna and wild hair. The cultural heritage of the area, including the Orthodox churches and monasteries of the 14th century, as well as the architectural values of the authentic villages, are irreplaceable and must be protected for future generations. The preservation of these natural and cultural assets is important to ensure that income and resources from tourism and other economic activities in the area are sustainable and expandable over time. In addition, the preservation of the natural environment and cultural heritage is part of our shared responsibility towards cultural heritage and ensures that future generations have the opportunity to enjoy and breathe in the valuable assets of Deçan. The study in this paper focuses on the importance of sustainable use of natural resources - surface water resources and the need for their effective management to preserve the integrity of this important natural and cultural area of Nemuna Mountains National Park. The purpose of this paper is to inform about the reality we have in this field, to promote these resources we have, their importance for the region, as well as to somehow influence the mobilization of citizens and all actors - responsible for preserving, using and promote these natural assets that are important to us in general. Therefore, strategies must be created by the Government of Kosovo to preserve and promote these natural and cultural assets for the benefit of our country.
