Cruise tourism is expanding everywhere, despite the pandemic; CLIA (2021) reports that, in 2020, the economic damage was around 77 billion dollars, but records a significant increase in travelers who aspire to join a cruise. Cruise ships and their economic impact have been the subject of research for many years and the data, which can be obtained from various sources, denote the importance of this particular sector. Through the MSC case study, this contribution aims to partecipate in the reflection on the theme of sustainability, to look at the possibility of directing cruise tourism towards a new way of introducing Man into the landscape.

The purpose of this work is to illustrate the didactic usefulness of the Congo-Nile Divide. The cartographic analysis (at the appropriate scale) of some important geographical objects allows to analyze the action of unification of the territory, action carried out by the objects themselves. This action, in fact, even when it seems to divide, generates a connecting hinge (as in the case of the Congo River, that partially marks the border between the two States of the same name). Inspired by Buache river basin theory, we could, therefore, propose a theory of unifying river basins.
