Policymakers must take action immediately to mitigate the risk of severe disruption at certain ports, maritime straits, and inland transport routes, which could have devastating knock-on effects for global food security.
Below we provide examples of disruptions and transit delays that have occurred in major food trade chokepoints since 2002. These examples were used to inform Table 2 in Section 3.4, which indicates the relative risk of disruption or passage restriction at each of the 14 chokepoints featured in this report.
The list of disruptions is far from comprehensive; instead, it is intended to be an illustrative overview of the heterogeneity and frequency of small- or medium-scale disruptions at key trade chokepoints over a period of 15 years. Our analysis classifies chokepoint hazards into three categories – weather and climate risk; security and conflict risk; and political and institutional risk – and further divides these into subcategories, such as ‘haze and fog’, ‘trade and transit controls’ etc. (see Table 10). The illustrative list of disruptions (Table 11) assigns each historical example of disruption to one of these 11 subcategories.
We identified and compiled examples of disruption through a desk-based review of news reports and open-source literature from industry, academia and civil society; in the absence of an existing framework for the reporting of chokepoint disruptions, there was limited potential for a more methodical approach. We believe that a robust, systematic approach to documenting chokepoint disruptions and quantifying their impacts on food trade is urgently needed to support the effective assessment and management of chokepoint risk.
A maximum of three incidents are noted for each hazard category. Key search terms were in English; foreign-language material was not included. Examples of weather- and climate-induced disruptions and of politically and institutionally induced disruptions are limited to those with a reported impact on freight operations. Examples of conflict- and security-related incidents, on the other hand, include attempted attacks and events that had no reported impact on traffic. The authors understand these incidents to be qualitatively distinct from those relating to weather and political effects. Terrorist activity, breakouts of armed conflict and state-led attacks on vessels are considerably less likely to affect chokepoint transit in the short term, but have broader and longer-lasting implications for food trade and prices (e.g. as a deterrent to commercial or humanitarian shipments, or as a source of upward pressure on transport costs and food prices if war insurance premiums are raised).
Some further general caveats and specific points merit explanation:

* Owing to the often high number of attempted or successful pirate attacks – small- or large-scale – individual incidents are not included in Table 11. Instead we note below those maritime chokepoints where many instances of piracy have been reported over the period 2002–17.
Piracy is a pervasive threat to trade through the Strait of Bab al-Mandab, the Strait of Malacca and, to a lesser extent, the Strait of Hormuz; countless instances of attempted and successful pirate attacks have been reported at each chokepoint over the period 2002–17. Details of the frequency and nature of these incidents are provided by the International Maritime Bureau (IMB)’s Piracy Reporting Centre.349 The UN Office on Drugs and Crime also provides analysis of the incidence of piracy.350
