This article examines the impact of natural and anthropogenic processes on the development of the port city of Poti, with a particular focus on managing landscape dynamics in the context of interactions between marine, riverine, and lacustrine systems. The study aims to identify key ecological and infrastructural risks and to develop strategies for their mitigation, response, and recovery. The methodology includes cartographic and historical-comparative analysis, field surveys, data systematization on natural and engineering components, as well as scenario modeling of the city’s landscape-urban platform. The article presents risk classification tables, schemes, and maps that illustrate the interactions between natural and engineered systems. A conceptual framework is proposed for the creation of new port nuclei in transformed landscape conditions, alongside the development of adjacent urban infrastructure. The paper also provides recommendations for Integrated Coastal Zone Management (ICZM), green infrastructure development, and the involvement of local communities in the planning process. The results can be used to inform adaptive strategies for the sustainable development of small coastal port cities, especially under the conditions of climate change.
