International Transport Forum Warns Drought-Driven Low River Levels
International Transport Forum (ITF) warns that drought-induced low river levels disrupt inland navigation, reduce cargo capacity, and increase freight costs. The warning highlights impacts on major river systems and outlines adaptation strategies for inland waterways and multimodal transport.
ITF Warning:
| Dimension | Key Details |
|---|---|
| Major affected European rivers | Affected European rivers include the Rhine, Danube, Loire, and Po. |
| Rhine discharge projection | Under high-emission scenarios, Rhine summer discharge may decrease by up to 10% by 2050. |
| Recent barge capacity declines | In August 2026, Rhine barge capacity decreases to approximately 15% of normal levels, and Danube capacity declines to about 30%. |
| Amazon drought impact | Severe droughts disrupt navigation and limit access to food, fuel, medicines, and essential services. |
| Inland waterways freight share | Inland waterways account for 15 to 45% of freight transport, measured in tonne-kilometres, in Belgium, China, the Netherlands, and Romania. |
| United States river transport share | Approximately 92% of agricultural exports are transported via river systems. |
| Rhine freight categories | The Rhine serves as a major transport route for fuels, chemicals, and grains. |
| Supply chain impacts of low water levels | Low water levels reduce barge capacity, necessitate more trips, increase freight costs, cause delays, lead to port congestion, and result in economic losses. |
| Germany GDP and industry impact | In Germany, low-water conditions on the Rhine in 2018 are associated with a 0.4% decline in GDP, and industrial production is estimated to decline by approximately 1% during a month of severe low-water conditions. |
| Constraints in shifting to rail | Rail networks are often already heavily utilized and are vulnerable to disruptions caused by extreme heat. |
| Constraints in shifting to road | Shifting freight to road transport requires significantly greater capacity. |
| Capacity equivalence example | A single barge with a capacity of 1,500 tonnes is equivalent to approximately 60 trucks, each carrying 25 tonnes. |
| Adaptation strategies | Adaptation strategies include: enhancement of water-level forecasting capabilities; deployment of shallow-draft vessels; implementation of water retention measures during periods of high precipitation; regulated releases of reservoir water; execution of emergency dredging operations; pre-positioning of essential stocks and storage facilities; integration of inland waterways, rail, and road within multimodal transport systems. |
| Germany water-level forecasting | Germany offers water-level forecasts extending up to 6 weeks for the Rhine, Danube, and Elbe rivers. |
