Information about natural and economic conditions in the Vistula lagoon together with directions of development of municipalities around the lagoon is presented in the report. The review of directions of development show that all municipalities aim to develop tourism, harbours and land transport. Moreover, Polish municipalities give large attention to environmental protection. In the future the development towards these strategic directions will continue together with an increased role of environmental protection and consequences of climate changes. Assessment of tolerance of Vistula Lagoon municipalities’ development strategies to climate changes have shown that directions of Polish municipalities’ development is less tolerant to consequences of climate change because of a large area disposed to possible flooding, and therefore possibly high expenses for prevention of territory flooding. The Vistula Lagoon is a subject of high anthropogenic pressure and some consequences due to climate changes were discussed. Obviously, due to different economic experience, economic systems and future plans the pressure will not be equal in Polish and Russian parts of the lagoon. Complex measures on modernization of monitoring climate changes and adaptation as well as strong cooperation between all municipalities around the Vistula Lagoon are essential.
