The partitioning of the river due to the construction of hydroelectric power plants, excessive sediment extraction, the development of navigation and the development of the so-called grey infrastructure for flood defence are the biggest threats for the Sava River. Barriers in the river prevent the migration of aquatic organisms and the transport of sediment, which is why incision of the riverbed is happening and the groundwater level has been lowered by few meters. By disrupting the water's ecosystem, natural purifiers - organisms that feed on organic matter - disappear. If the trend of lowering groundwater continues, forests and agricultural areas will dry out even more. It will also seriously endanger water wells from which the city of Zagreb and other settlements get its drinking water. Not to mention the stability of buildings near the river, which would be greatly disrupted.
At the international level, the management of the Sava River is based on the Sava River Basin Management Plan
implemented by the International Sava River Basin Commission. All the states along the Sava's course have formed several national bodies that manage the river within their scope of activities and competencies.
Members of the SavaParks Network also participated in the development of different publications such as the Sava White Book and the Eco-Master Plan for Balkan Rivers, which provide recommendations for river management based on the latest knowledge and offer solutions for sustainable river management for the benefit of people and nature. The Sava White Paper is available on this website under the category "Publications", and the Eco-master plan for Balkan Rivers was developed by RiverWatch from Austria and EuroNatur from Germany and is available on their websites or at this link
