Coastal Environments: Threats to Investment Processes in the Coastal Area

One of the key problems humanity faces in this age of profound digitalization is globalization-related threats, which no longer affect just one country but pose a threat to a very large area, encompassing several or even a dozen countries, or, in the case of global warming, a threat to all of humanity worldwide. This topic inspired the investigation and verification of this threat in the Baltic Sea, along with other threats operating in the Baltic Sea region. This topic is highly topical, as estimates from maritime institutions indicate that the rate of sea level rise is an irreversible process, which, when combined with other threats, could lead to the degradation of the sea and the population living in the coastal zone. This led to the delegation clarifying the main objective of the article: to demonstrate the impact of potential global threats on the investment process in the Polish coastal belt. Based on this, an analysis of threats in the Baltic Sea region was conducted, preceded by a review of the literature and data from online resources, including data from industry portals in the maritime sector. This article presents a simulation of erosion-accumulation changes in selected areas of Poland’s Southern Baltic coast, focusing on the coastal real estate market and indicating the propensity to invest in these areas. Simulating erosion changes, using a cartographic base with a generated digital terrain model and interpolation tools to visualize the changes, represents an innovative approach to issues related to the outflow of investment land in the real estate market. This emphasizes the directionality of land changes, thus providing a predictive tool for decision-making and spatial planning in the coastal area.
