Researchers worldwide register continuous socio-spatial polarization connected with the effect of coastalization. It reputedly has the perceptible impact on the increasing regional divergence with the coastal areas exceeding inland territories on a number of socio-economic indicators. A few studies analyze the change in strength of the coastal (marine) influence depending on the distance of the coast, but none focus on the issue of regional segregation to explore the cross-influence of other geospatial particularities. Article presents the results of the statistical analysis of European territories at regional level with regards to the impact of proximity to both the coast and border on regional development. The study refuted a hypothesis on the prevalence of coastal regions in terms of population and GRP. However, our results do confirm the existence of the coastalization effect and its significant impact on the socio-economic development of all types of regions identified, dominated by both coastal and border proximity. A significant impact of the coast over the development of inland regions has predetermined the allocation of a special regional subtype – coastal hinterland, characterized by increased economic efficiency values. The coastal border regional subtype displays a number of distinctive features stemming from a simultaneous impact of coastal and border proximity. Article concludes with policy implications for implementing coastal zone management in coastal border regions.

Coastal areas represent complex environmental systems, as they are controlled by a high number of interacting variables (forcing factors, processes), acting over different time scales. Relevant factors enhancing global and local coastal trends are also the local scale boundary conditions, such as those related to the watershed dynamics and anthropic load.
Coastal plains are sensitive to the combined effects of subsidence and extreme events, such as storm surges, that can trigger erosional and flooding processes and cause rapid land modifications. Climate change effects can increase the intensity of these processes, enhancing the susceptibility of such areas.
Coastal cliffs represent the main part of the world’s coastline (Emery and Kuhn 1982). Active coastal cliffs are exposed to a continuous geomorphic evolution mainly controlled by wave action. Beside wave action, wind, rain, salt spray, wetting and drying cycles, changes in temperature, bio-erosion, are among the most effective weathering agents that contribute to the geomorphological evolution of cliffs.
Different retreat rates through time are reported worldwide. The knowledge of retreat rates is important because it allows one to assess the level of risk for coastal assets (Lee 2002), to mitigate the potential impacts of cliff instability and erosion through various adaptation measures (Moore and Davis 2015), and to predict future trends even without sea level rise (Bray and Hooke 1997).

This article explores the arguments for expanding deliberation in the Intergovernmental Panel on Climate Change (IPCC) and scrutinizes their implications for the deliberative capacity of global environmental governance (GEG). An analysis of the IPCC is presented that builds on a systematic literature review and thus a broad set of scientific debates concerning the IPCC. Based on this analysis, two different paths are outlined, one moderate and one radical; these paths ascribe different democratizing functions to the IPCC and rely on different epistemologies. The moderate path emphasizes decision capacity, whereas the radical path strives to create deliberative space and to identify the value inherent in different claims. It is argued that the IPCC cannot accommodate the aspirations of these different pathways in a single assessment. Parallel assessments must be developed in complementary subject areas with different science-policy relations.
Keywords: IPCC; Deliberative capacity; Global Environmental Governance (GEG).
