Sustainable Freight Networks and Urban-Regional Logistics: Lessons from European Transport Systems for Emerging Eurasian Corridors

Sustainable Freight Networks and Urban-Regional Logistics: Lessons from European Transport Systems for Emerging Eurasian Corridors

Abstract

The growing geopolitical significance of the Trans-Caspian International Transport Route (Middle Corridor) has intensified interest in alternative Eurasian freight routes connecting Europe and Asia. While existing literature largely examines geopolitical and infrastructural dimensions, limited attention has been devoted to the spatial-economic impacts of freight corridor development on intermediary regions and secondary cities. This article investigates how logistics networks reshape regional economies, transport accessibility, and territorial development along the South Caucasus section of the Middle Corridor. Combining economic geography, freight transport studies, and regional development approaches, the paper proposes an analytical framework for examining emerging logistics spaces. Particular attention is devoted to Georgia as a strategic transit country. The article argues that corridor development generates uneven regional opportunities and challenges requiring integrated governance approaches.

Keywords: Middle Corridor, freight transport, economic geography, logistics, regional development, South Caucasus, transport corridors.

1. Introduction

The global logistics system is experiencing profound transformations resulting from geopolitical tensions, supply chain disruptions, climate concerns, and changing trade patterns. The COVID-19 pandemic, the Suez Canal blockage in 2021, and the Russian-Ukrainian war have demonstrated the vulnerability of established Eurasian transport corridors (Notteboom et al., 2021).

As a consequence, policymakers increasingly promote alternative transport routes linking Europe and Asia. Among these, the Trans-Caspian International Transport Route-commonly known as the Middle Corridor-has emerged as a strategic alternative.

The corridor links China to Europe through:

• Kazakhstan
• the Caspian Sea
• Azerbaijan
• Georgia
• Turkey
• the European Union

European institutions increasingly recognize its strategic importance for transport resilience and supply-chain diversification.

However, most studies concentrate on:

• geopolitics,
• trade volumes,
• infrastructure investments,
• international relations.

Far less attention is devoted to:

• regional development impacts,
• logistics geography,
• spatial inequalities,
• local economic transformations.

This article addresses this gap.

2. Theoretical Framework

2.1 Transport Corridors and Economic Geography

Transport corridors have long been regarded as engines of regional development.

Taaffe et al. (1963) demonstrated how transport networks influence national development patterns.

Rodrigue et al. (2020) argue that freight systems shape:

• accessibility,
• investment,
• economic specialization.

Economic geography literature suggests that infrastructure creates uneven development effects (Martin & Sunley, 1998).

Corridors often generate:

• growth poles,
• logistics hubs,
• peripheral regions.

2.2 Logistics and Spatial Transformation

Logistics is increasingly recognized as a spatial process.

Hesse and Rodrigue (2004) introduced the concept of logistics sprawl.

Freight networks influence:

• warehouse location,
• industrial clustering,
• retail distribution,
• labor markets.

Janelle and Beuthe (1997) emphasize that freight mobility reorganizes economic spaces.

2.3 Regional Resilience

Regional resilience refers to the ability of territories to adapt to external shocks.

Martin (2012) identifies:

• resistance,
• recovery,
• reorientation.

The Middle Corridor offers countries such as Georgia opportunities to improve resilience by diversifying economic activities.

3. Literature Review

Research on Eurasian transport corridors has expanded considerably.

Pomfret (2019) discusses Belt and Road transport connectivity.

Vinokurov et al. (2018) examine Eurasian logistics integration.

The European Commission increasingly highlights transport diversification strategies.

However, three gaps remain:

Gap 1: Local Impacts

Most studies operate at international scales.

Gap 2: Freight Geography

Little attention is given to logistics systems.

Gap 3: Regional Development

Few studies investigate effects on intermediary regions.

4. The Middle Corridor as an Emerging Freight Network

The Middle Corridor has experienced rapid growth.

Container volumes increased significantly after 2022.

Several factors explain this:

• sanctions against Russia,
• supply-chain diversification,
• geopolitical risks,
• European strategic interests.

Georgia occupies a particularly important position because it hosts:

• Black Sea ports,
• railway connections,
• logistics centers,
• east-west highways.

Key infrastructure includes:

• Baku–Tbilisi–Kars railway,
• East-West Highway,
• Poti port,
• Batumi port.

5. Research Questions

1. How does the Middle Corridor reshape regional freight networks?
2. What spatial inequalities emerge along the corridor?
3. Which regions benefit most from logistics investments?
4. How can governance improve territorial outcomes?

6. Methodology

The research adopts a mixed-method approach.

Spatial Analysis

GIS analysis:

• accessibility measures,
• freight flows,
• infrastructure density.

Statistical Analysis

Indicators:

• employment,
• investments,
• logistics activities.

Interviews

Stakeholders:

• freight operators,
• municipalities,
• logistics companies,
• port authorities.

Policy Analysis

Review of:

• EU policies,
• Georgian transport strategies,
• corridor initiatives.

7. Case Study: Georgia

Georgia represents an ideal laboratory.

Its territory connects:

• Central Asia,
• the Black Sea,
• Europe.

Logistics hubs include:

• Tbilisi,
• Poti,
• Batumi,
• Kutaisi.

Yet development remains uneven.

Mountainous regions often remain disconnected.

Infrastructure investments concentrate along principal corridors.

8. Logistics Hubs and Urban Development

Urban logistics increasingly influences:

• land use,
• real estate,
• employment.

Tbilisi is emerging as:

• distribution center,
• consumption market,
• logistics node.

Poti serves as:

• maritime gateway.

Secondary cities may benefit from logistics decentralization.

9. Governance Challenges

Several challenges emerge:

Institutional Fragmentation

Multiple agencies operate independently.

Cross-border Coordination

International cooperation remains limited.

Environmental Sustainability

Freight transport contributes to emissions.

Social Equity

Benefits may concentrate among large firms.

10. European Lessons

Rather than presenting Europe as a separate section, comparison can strengthen the paper.

Examples include:

• Belgian logistics regions,
• Dutch freight corridors,
• German inland ports.

Antwerp provides an excellent example of:

• integrated freight planning,
• multimodal transport,
• logistics clustering.

Lessons include:

• governance integration,
• spatial planning,
• sustainable freight systems.

11. Policy Implications

Policy recommendations include:

• multimodal logistics planning;
• regional freight strategies;
• corridor governance institutions;
• environmental assessments;
• inclusive development policies.

12. Conclusion

The Middle Corridor represents more than an international transport route.

It constitutes a process of spatial transformation.

The South Caucasus offers an important laboratory for understanding:

• emerging freight geographies,
• regional development,
• logistics governance.

The integration of economic geography and transport studies provides new perspectives for both scholarship and policy.
