Regional integration and maritime connectivity across the Maghreb seaport system

Models and empirical studies of port system evolution dominantly focus on land-based dynamics. Hence, it is traditionally recognized that such dynamics condition the evolution of ports and their relations as well as wider regional integration processes. The Maghreb region (Algeria, Morocco, and Tunisia), which is currently responsible for no less than one-third of all African port throughputs, offers a fertile ground to test the possibility for regional integration to occur through maritime linkages despite limited trade integration and land-based transport connectivity. Main results highlight the increase of trans-Maghreb maritime connectivity but this occurs mostly at the periphery of the system based on transit flows. Logistical integration versus trade integration is discussed in light of the recent evolution of Maghreb ports and of the region in general.

Development of seaport–dry port dyads: two cases from Northern Europe

An increase in sea freight flows generates an almost proportional increase in inland freight flows, and what takes place inland will influence the ability of intermodal transport systems to further accommodate the growth of international trade. This could be facilitated by dry ports, which have been developed to support seaport operations as well as the overall operations of intermodal transport systems.The aim of this paper is to develop the Wilmsmeier et al. (2011) framework of directional development by taking into account development over time. The purpose is to contribute to the understanding of the development of seaport–dry port dyads by the analysis of two in-depth case studies from Northern Europe. A qualitative research strategy is applied to increase understanding of the development. The results contribute to earlier studies of spatial development of seaport–dry port development by taking into account development over time and by increasing the understanding of the actors, the types of dry ports and the services influencing the development of the dyads.     

Governing inland ports: a multi-dimensional approach to addressing inland port–city challenges in European transport corridors

Inland ports have been put forward as crucial linkages for efficient global freight transport and corridor development. However, the present understanding of inland ports appears to be limited to network-based views with a maritime port focus (Outside-In), in which inland ports play second fiddle. We argue that inland ports as independent structures (Inside-Out) deserve equal consideration and that in addition to the transport dimension, the spatial, economic and institutional dimensions of inland ports are vital and should not be neglected. The goal of this paper is to apply the concept of port–city challenges to inland ports. The results of an institutional analysis of Dutch case study evidence show that challenges facing inland ports and cities take many forms but that all share a commonality in the trade-offs between positive and negative externalities. We observe different governance strategies in coping with these trade-offs and find that a proactive stance towards zoning contributes to efficiently accommodating mutually exclusive dimensions of inland port development.     

Going West? Spatial polarization of the North Korean port system

This paper analyzes North Korean ports in light of existing models of port system evolution. It reviews the economic and political factors shaping port concentration in developed, developing, and socialist countries. A database on vessel movements allows for the analysis of individual North Korean port traffic by total capacity circulated, cargo type, fleet nationality, immediate origin and destination, and berthing time. While ideological factors and military control hamper port modernization and trade openness, traffic concentration at the Pyongyang–Nampo gateway highlights the spatial polarization in the capital region at the expense of Eastern ports for which inland transport limitations and industrial decline have become major issues. The North Korean case only partly fits general models because traffic concentration occurs due to geopolitical isolation and internal limitations rather than economic and trade growth.
