MSP EU Legend 8

This map was compiled from different international sources such as EMODnet, EEA or Marine Regions. Information obtained from these sources was cross-checked with data from national sources. While compilation was carried out by the European MSP Platform, validation and quality assurance remain the responsibility of the primary data sources.

Basic facts on Marine Waters

  • Slovenia's internal waters cover 46.3km² and its territorial sea, out to 12 nautical miles (as defined by UNCLOS) cover 166.9 km²
  • On 29 June 2017, the Arbitral Tribunal rendered its “Final Award” in the arbitration concerning a territorial and maritime dispute between the Republic of Croatia and the Republic of Slovenia.

MSP legislation

The EU MSP Directive is transposed into naional legislation through the Spatial Planning Act adopted in 2017 (OG no. 61/17 – ZUreP-2). The Spatial Planning Act requires the MSP plan to be prepared in the form of the Action Programme for the implementation of the Slovenian Spatial Development Strategy at sea. The latter is a strategic document which applies to both land and sea. 

Currently, the Ministry of the Environment and Spatial Planning is coordinating the preparation of a new Spatial Development Strategy for Slovenia in 2050.

National MSP authority

Slovenia's competent authority for MSP is the Ministry of the Environment and Spatial Planning; Spatial Planning, Construction and Housing Directorate.
