Conflict Period

The main aim of our paper is to study peculiarities of two periods, i.e., the pre-conflict period (2004–2013) and conflict period (2014–2018), in the context of the impact of the demographic structure of the population on the economic growth and development of coastal regions of Ukraine. In the first step of the analysis, we investigate the relationship between the demographic shifts and selected economic indicators, using the Pearson’s correlation coefficient. In the next step of the analysis, we focus on the quantification of the impact of demographic indicators on the economic variables, based on the panel model with fixed effects. The received results confirm that the influence of the demographic stricture on the economic state of coastal regions changed significantly in the conflict period in comparison with the pre-conflict period, especially concerning income, unemployment, and the openness of the economy. Additionally, our findings show that while economic differences existed between the Azov Sea regions and the Black Sea regions in the pre-conflict period, they disappeared due to the economic deterioration of the Azov Sea regions during the conflict period. It is concluded that war affects adversely the population’s demographic structure, which inhibits the growth and economic development of Ukrainian coastal regions.

Abstract Adverse and dangerous natural processes are a deterrent factor in the economic, in particular, recreational use of the coastal territories of Russia. They significantly reduce their tourist potential. At the same time, a decrease in the recreational value of territories is one of the consequences of human impact on the natural landscapes of the coastal zone. It seems important to consider the impact of adverse and dangerous natural processes specifically for coastal recreational areas due to their exceptional importance for domestic tourism. It, in turn, plays a huge role both for the economy of Russia and certain regions of our country, and for Russians themselves: tourists and local residents. As a result of the research, for each of the seaside recreational areas available in Russia, the study revealed the most characteristic adverse and dangerous natural processes. Some of them are more or less manifested everywhere, for example, abrasion processes or storms. Others, in particular, seismic threat, are characteristic only for certain coastal territories. Measures to counteract dangerous natural processes are also somewhat similar for all the regions considered. However, when developing measures to counteract adverse and dangerous natural processes, the peculiarities of coastal regions should also be taken into account. Such features include climatic and relief characteristics, the landscapes of the region, the existing structure of human activity and the intensity of economic development of the region, the types of tourism that are characteristic of it, and the level of popularity of the region among recreants, as well as its recreational potential.

The Impact

The article is devoted to the identification of modern factors influencing the development of the cluster of Arctic coastal regions and the development of proposals to reduce the risks of economic security, taking into account the specific features of the development of these territories. A lot of research works have been devoted to aspects of the economic security of the Arctic coastal regions, and there is also an interest on the part of the state to address issues of balanced development of the Arctic territories, which is expressed in a systematic approach implemented through a number of strategic documents, including the Economic Security Strategy of the Russian Federation for the period up to 2030. Despite this, the change in modern realities requires constant adjustments to existing documents and forecasts affecting the regional specifics of economic security and Arctic coastal regions, from the perspective of the influence of various factors, such as, for example, sanctions, the COVID-19 pandemic, instability of world commodity markets, the introduction of green technologies, changing priorities in the development of Arctic regions.

Abstract. The western Baltic Sea is impacted by various anthropogenic activities and stressed by high riverine and atmospheric nutrient loads. Atmospheric deposition accounts for up to a third of the nitrogen input into the Baltic Sea and contributes to eutrophication. Amongst other emission sources, the shipping sector is a relevant contributor to atmospheric concentrations of nitrogen oxides (NOx) in marine regions. Thus, it also contributes to atmospheric deposition of bioavailable oxidized nitrogen into the Baltic Sea. In this study, the contribution of shipping emissions to the nitrogen budget in the western Baltic Sea is evaluated with the coupled three-dimensional physical biogeochemical model MOM-ERGOM in order to assess the relevance of shipping emissions for eutrophication. The input of bioavailable nitrogen impacts eutrophication differently depending on time and place of input – e.g. nitrogen is processed and denitrified faster in flat coastal regions. The shipping sector contributes up to 5 % to the total nitrogen concentrations in the water. The impact of shipping-related nitrogen is highest in the off-shore regions distant to the coast in early summer but is considerably reduced during blooms of cyanobacteria in later summer. Although absolute shipping-related total nitrogen concentrations are high in some coastal regions, the relative contribution of the shipping sector is low in the vicinity to the coast because of high riverine nutrient loads.
