As Europe’s historically dry summer continues, Matthew Kenyon takes a trip on the barge Mezzoforte, and talks to skipper Dirk Pols about the challenges of navigating as river depths fall. We hear from Cornelis van Dorsser of the Dutch Inland Shipping Association about how the industry is preparing for the continued impacts of climate change. Economist Saskia Meuchelböck tells us about the economic effects of the last major dry period, just four years ago, when a month of low water on the Rhine knocked 0.4% off Germany’s GDP, and hydrologist Saskia Werners explains how barge captains, industry, importers and the public have to expect more of the same.
