Project – Impact of Global Shipping Disruptions on Inflation and Food Security in Sub-Saharan Africa

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Global shipping systems form the backbone of international trade, with over 80% of world merchandise trade by volume transported via maritime routes. These shipping networks are highly concentrated in a few strategic chokepoints such as the Suez Canal, Panama Canal, Strait of Malacca, and major port hubs across Asia, Europe, and the Middle East. Any disruption in global shipping—whether caused by geopolitical tensions, pandemics, piracy, port congestion, or climate-related shocks—has immediate and far-reaching consequences for global supply chains (UNCTAD, 2024).

In recent years, global shipping disruptions have become more frequent and severe. Events such as the COVID-19 pandemic, the blockage of the Suez Canal in 2021, the Russia–Ukraine conflict, and ongoing Red Sea insecurity have exposed the fragility of global logistics systems. According to the World Trade Organization (WTO, 2024), these disruptions have led to increased shipping costs, longer delivery times, and volatility in global commodity markets, especially food and energy.

Sub-Saharan Africa is particularly vulnerable to such disruptions due to its heavy reliance on imported food commodities. Many countries in the region depend on global markets for wheat, rice, fertilizers, edible oils, and processed food items. As a result, disruptions in global shipping routes directly affect food availability and pricing in domestic markets. The World Bank (2023) notes that imported food accounts for a significant share of caloric consumption in urban populations across Sub-Saharan Africa, making the region highly sensitive to global supply chain shocks.

Inflation in Sub-Saharan Africa is also strongly influenced by external supply-side shocks. When global shipping costs rise, import prices increase, leading to higher domestic food prices. Food inflation constitutes a large portion of overall inflation in most African economies, often exceeding 40% of the consumer price index in some countries (IMF, 2024). This means that disruptions in maritime logistics quickly translate into rising cost of living and reduced household purchasing power.

Food security is defined by the availability, accessibility, utilization, and stability of food supplies. Global shipping disruptions undermine all four pillars of food security. Reduced shipping capacity leads to delays in food imports, shortages in local markets, and increased price volatility. In conflict-affected or low-income regions, these disruptions can result in acute food insecurity and malnutrition. The Food and Agriculture Organization (FAO, 2024) reports that global supply chain shocks have significantly increased the number of food-insecure people in Sub-Saharan Africa over the past decade.

Furthermore, climate change and infrastructural inefficiencies in African ports exacerbate the impact of global shipping disruptions. Poor port logistics, limited storage facilities, and weak transport networks increase the time and cost required to distribute imported food across inland regions. This creates localized scarcity even when global supply is sufficient.

In essence, global shipping disruptions are not only a trade issue but also a major macroeconomic and humanitarian concern for Sub-Saharan Africa. They influence inflation dynamics, food availability, and household welfare. Understanding this relationship is critical for developing resilient food systems and effective policy responses in the region.

1.2 Statement of the Problem

Despite globalization and improvements in international trade systems, Sub-Saharan Africa remains highly exposed to external shocks due to its dependence on imported food and weak domestic agricultural productivity. The increasing frequency of global shipping disruptions poses a serious threat to economic stability and food security in the region.

Recent global events have demonstrated how fragile maritime supply chains can significantly affect food prices. For instance, disruptions such as port congestion, container shortages, and geopolitical conflicts have led to increased freight rates and delays in food imports. According to UNCTAD (2024), global shipping costs in some periods increased by over 300% compared to pre-disruption levels, with significant spillover effects on food-importing developing countries.

In Sub-Saharan Africa, these increased shipping costs are quickly transmitted to domestic markets, leading to higher food inflation. The IMF (2024) reports that food price inflation is a major driver of overall inflation in many African economies, often accounting for more than half of headline inflation rates. This reduces real incomes and disproportionately affects low-income households, who spend a large share of their income on food.

Food insecurity is also worsening as supply chain disruptions limit the availability and affordability of essential food commodities. Delays in shipments of grains, fertilizers, and edible oils reduce food supply stability and increase reliance on emergency imports. The FAO (2024) highlights that millions of people in Sub-Saharan Africa are facing acute food insecurity due to a combination of climate shocks, conflict, and global supply chain disruptions.

Another key problem is the limited resilience of African logistics and storage systems. Weak port infrastructure, inadequate cold storage facilities, and poor inland transportation networks worsen the effects of global shipping disruptions. Even when food imports arrive, inefficiencies in distribution often lead to localized shortages and price disparities across regions.

Despite the severity of these challenges, there is still limited region-specific empirical research that examines the direct link between global shipping disruptions, inflation, and food security in Sub-Saharan Africa as an integrated system. Most studies treat inflation and food security separately, without adequately capturing the role of global logistics shocks as a transmission mechanism.

This gap in knowledge limits policymakers’ ability to design effective interventions that strengthen supply chain resilience and stabilize food markets. Therefore, a comprehensive analysis of how global shipping disruptions affect inflation and food security in Sub-Saharan Africa is necessary.

1.3 Objectives of the Study

The main objective of this study is to examine the impact of global shipping disruptions on inflation and food security in Sub-Saharan Africa.

Specific objectives include:

1. To assess the effect of global shipping disruptions on food import costs in Sub-Saharan Africa.
2. To examine the relationship between shipping disruptions and inflation rates in the region.
3. To evaluate the impact of food price inflation on food security outcomes.
4. To identify policy strategies for improving supply chain resilience and food system stability.

1.4 Research Questions

1. How do global shipping disruptions affect food import costs in Sub-Saharan Africa?
2. What is the relationship between shipping disruptions and inflation in the region?
3. How does food inflation influence food security outcomes?
4. What measures can improve resilience in food supply chains?

1.5 Research Hypothesis

H₀: There is no significant relationship between global shipping disruptions and inflation and food security in Sub-Saharan Africa.

H₁: There is a significant relationship between global shipping disruptions and inflation and food security in Sub-Saharan Africa.

1.6 Significance of the Study

This study is significant to policymakers, economists, and development agencies working in Sub-Saharan Africa. It provides insights into how global logistics disruptions affect inflation and food security, helping governments design better trade policies, food import strategies, and emergency response mechanisms. It also contributes to academic literature on global supply chain resilience and macroeconomic stability in developing economies.

1.7 Scope of the Study

The study focuses on the impact of global shipping disruptions on inflation and food security in Sub-Saharan Africa. It covers major transmission channels such as freight costs, import dependency, food price inflation, and household food access.
