Shipping Trade and Geopolitical Turmoils: The Case of the Ukrainian Maritime Network

Fabio Cremaschini, César Ducruet, Marc-Antoine Faure, Bárbara Polo Martin

Abstract

Conflicts, whether political, commercial or military, affect transport networks. Operators seek to avoid the most tense areas or reconsider certain routes. Certain links can be disrupted in case of local geopolitical tensions, which can have a significant global impact. The article is devoted to studying Ukraine’s maritime network and identifying changes in these structures because of the conflict that started in 2014. The purpose of the paper is to measure and visualise the main changes in the Ukrainian seaport system and maritime forelands from 2010 until the most recent data available (December 2023), from a network models, bilateral trade and route simulation framework. The principal results confirm the huge impact of military conflict on port connectivity, thereby contributing to the recent literature on shipping network vulnerability.

Abstract

Despite the skyrocketing growth of environmental studies in recent decades about ports and shipping, the local health impacts of ports remain largely under-researched. This article wishes to tackle this lacuna by statistically analyzing data on global shipping flows across nearly 5,000 ports in 35 OECD countries between 2001 and 2018. The different traffic types, from containers to bulks and passengers, are analyzed jointly with data on natural conditions, air pollution, socio-economic features, and public health. Main results show that port regions pollute more than non-port regions on average, while health impacts vary according to the size and specialization of port regions. Three types of port regions are clearly differentiated, of which industrial, intermediate, and metropolitan port regions.
