International Symposium

Multidisciplinary symposium as part of the ANR (French National Research Agency) Project “Contemporary Challenges of Straits” – DéCoDé

DUNKIRK (FRANCE) 09 - 11 December 2025

Argument

Straits—narrow maritime corridors connecting two larger bodies of water bordered by closely situated landmasses—occupy a strategic position within global geography due to their essential role in maritime transit (Lasserre, 2010). While often functioning as boundaries between states or even continents, straits also serve as liminal spaces—interstitial zones (Mareï & Baron Yellès, 2013) or terraqueous frontiers (Picouet & Renard, 2002)—which both divide and connect (ibid.).

By shortening transit times and streamlining commercial exchange, straits have become central nodes in the maritime dimension of globalization—simultaneously acting as hinges and borders between territories (Semmoud, 2009). This centrality has generated multifaceted geopolitical and power-related stakes of interest to all maritime powers, past and present—states, empires, and beyond (DelfourSamama, 2016; Lebreton, 2016; Rodier, 2021). However, the role of the strait should not be reduced to longitudinal transit alone. Though less frequently studied or publicized, transversal exchanges represent a significant, if underexplored, dimension of strait-based navigation.

The geographical narrowness of straits and the need to structure and intensify transversal connections have led littoral states to conceive—and sometimes construct—major transport infrastructures such as bridges and tunnels. What technical, political, environmental, or economic obstacles have these projects encountered? Why have some remained unrealized? What are, or could be, the consequences of such infrastructures for strait dynamics and the relations between neighbouring states? Other infrastructural elements—particularly ports, undersea cables, and pipelines—also play a crucial role in shaping straits' functionality and strategic character.

These are some of the central questions to be explored in this conference, which invites contributions from a wide range of disciplines (Urban Planning, Geography, International Law, History, Economics, Sociology, and Management Sciences, among others). Drawing upon diverse empirical objects and employing varied but complementary methodologies, the colloquium aims to provide a multidisciplinary analysis of straits through the lens of their infrastructures—emphasizing their historical significance, governance challenges, and dynamic transformations.

The organizing committee has identified three primary thematic axes, although submissions outside these categories will also be welcomed.

Thematic area 1: Crossing and Controlling Maritime Straits – an Historical perspective

The historical study of infrastructure in straits reveals persistent tensions between engineering challenges, geopolitical imperatives, and commercial ambitions. From Xerxes’ floating bridge across the Hellespont (480 BCE) to the contemporary Channel Tunnel (1994), from historical visions of a Bosphorus crossing to ongoing debates surrounding projects in the Bering and Gibraltar straits— including the Øresund Bridge—these infrastructures embody both scientific achievements and evolving international relations. They reflect shifting perceptions of strait traffic (longitudinal vs transversal, cooperation vs conflict, gateway vs bridge, real vs virtual, functional vs aesthetic).

Port infrastructure evolution further illustrates this trajectory: the Strait of Hormuz, for instance, has transitioned from 16th-century Portuguese feitorias to state-of-the-art terminals (Baronnet, 2022). Similarly, the development of Singapore at the Strait of Malacca and the rise of TangerMed at the Strait of Gibraltar are emblematic examples.

 This thematic area examines how, across different historical periods, infrastructure projects have not only met substantial technical challenges but have also reshaped and, at times, redefined global commercial, geopolitical, and technological relationships.

Thematic area 2: Technical and Logistical Complexity of Strait-Based Infrastructures

Straits represent areas of heightened engineering and logistical complexity. Submarine cable networks, pipelines, bridges, and tunnels face unique design, installation, and maintenance challenges. For example, deploying telecommunications or power cables necessitates detailed pre-installation studies of bathymetry, sediment composition, and marine currents, typically conducted via geophysical and geotechnical surveys (De Alte Riis et al., 2016). The strait’s width, water depth, and shoreline profile for above-surface infrastructure determine foundation type and material choice (e.g., high-performance concrete, high-strength steel).

Logistically, transporting construction components demands rigorous maritime and fluvial convoy planning, specialized vessels, and synchronized heavy-lift operations—often constrained by tidal cycles, weather conditions, and longitudinal and transversal traffic.

This thematic area invites analysis of the technical and logistical intricacies of strait infrastructures, from initial conception and construction to operational maintenance, within the navigational and environmental constraints specific to these unique maritime zones.

Thematic area 3: Vulnerability of Strait-Related Infrastructures in a reconfiguring World

This thematic axis focuses on the vulnerability of strategic infrastructures in or around straits, particularly in the face of geopolitical tensions, environmental threats, and global economic shifts. As critical nodes in international trade and maritime networks, straits host vital infrastructures such as bridges, tunnels, ports, pipelines, and surveillance or communication systems. The global submarine cable network, responsible for over 99% of Internet traffic, exemplifies its infrastructural centrality.

However, such cables raise significant issues of digital sovereignty due to their transnational routes, ownership structures, and susceptibility to external threats (Ganz et al., 2024). They are particularly exposed to mechanical damage and hybrid warfare activities, including surveying by hydrographic vessels or deliberate sabotage—highlighting the urgent need for international governance and protective frameworks (Bueger & Liebetrau, 2021). Similarly, bridges and tunnels are subject to persistent concerns over their vulnerability to a spectrum of threats: terrorism and sabotage (UN General Assembly Resolution A/65/37, 2011; Jenish, 2012), sea level rise, ecological disruption, migratory flow control, touristic development, and the aesthetic experience of built landmarks—frequently discussed in political, economic, environmental, and societal discourse.

This thematic area thus aims to foreground questions surrounding the resilience, security, and governance of strait-related infrastructures—analyzing how states and private actors navigate the management of critical, high-risk assets under conditions of uncertainty and transformation.

Proposal Guidelines

Proposals may relate to one or more of the three themes and focus on infrastructures in straits— ports, tunnels, bridges, submarine cables, and pipelines. They may adopt diverse geographical contexts and methodological approaches, from case studies to interregional or international comparisons.

Virtual sessions will be organized if necessary to facilitate broad participation.

Particular attention will be given to proposals by early-career researchers (PhD students, postdocs, recent graduates).
