Key insight

The Panama Canal crisis demonstrated that a single weather event (drought) can simultaneously trigger a global supply chain disruption — showing the systemic nature of climate risk in transport infrastructure beyond the asset itself.

Transferability to UK: LowLimited direct UK transport applicability.

Severe 2023 drought reduced Panama Canal reservoir levels to near-record lows, forcing the Panama Canal Authority to restrict daily transits from 36–38 to 24 and limit vessel draft — disrupting global shipping. Water-savings basins (capturing 60% of lockage water for reuse), cross-filling protocols, and a new fresh water surcharge were activated to manage reduced water availability while maintaining canal viability.

Adaptation measures

  • Water-savings basins in locks (60% water recovery)
  • Cross-filling between lock chambers
  • Fresh water surcharge for high-draught vessels
  • Draft and transit restrictions

Delivery period

—

  • The Panama Canal Authority (ACP) experiences severe drought conditions that have reduced water levels in Gatun and Alhajuela Lakes, vital for canal operations and water supply to 2.5 million people .
  • In 2023, rainfall dropped by 30%, leaving only 50% of the water needed for the 2024 dry season .
  • With each canal transit consuming significant freshwater, efficient water management has become essential to sustain operations and support local communities.
  • The longer term solution is to build a reservoir along the Indio River to increase the availability of fresh water however, this will flood some communities such as Limon, displacing local communities .

Transferability to UK: Low

Limited direct UK transport applicability. The water-savings basin technology and drought management protocols are of interest to UK inland waterway operators (Canal & River Trust) and water resource planners facing combined transport and water supply challenges.
