The need to prioritize activities aimed at increasing the use of inland waterway transport to support seaports and their staging is of primary importance for ports that have natural conditions (direct access to inland routes), but do not meet the basic requirements for their development (access to high-quality inland waterway connections). Due to the cost- and time-consuming nature of many of the recommended activities, it is crucial to properly plan internal and external measures by placing them on a timeline and assigning responsibility for their implementation to various stakeholders, including port authorities and waterway managers. Revitalizing the linear waterway infrastructure of these ports will be of paramount importance.
