Germany's dry rivers spark battle on engineering vs restoration

Germany finds itself in the midst of a heated debate over the future of its rivers as the country grapples with the impact of a severe heatwave and prolonged drought. Government ministers are divided on whether to invest in engineering solutions, such as deepening shipping channels and developing low-draft ships, or to restore rivers to their natural state, embracing a more environmentally-friendly approach.

Steffen Bilger, Germany's new transport minister, convened a crisis summit with industry leaders and proposed temporarily lifting a ban on Sunday and public holiday truck transports to mitigate the effects on cargo shipping. Bilger argued that the country needs to make its waterways more efficient while ensuring ships are suitable for periods of low water.

Meanwhile, Environment Minister Carsten Schneider of the junior coalition partner, the centre-left SPD, advocates for a shift back to natural rivers, featuring meandering branches and floodplains that retain water across the landscape. This vision aligns with environmental groups, who argue that deepening shipping channels and dredging rivers cause water to drain away faster, ultimately exacerbating the issue.

Critics warn that dredging is not a permanent solution, as rivers constantly fill the channels with new sediment. Environmentalists also express concern over the destruction of shallow-water zones where aquatic life and insects breed, as well as the loss of natural floodplains that act as sponges during periods of excess water. The opposition Greens accuse the Merz government of doing too little about the root cause of the problem, the climate crisis, and assert that the government's focus on engineering solutions instead of addressing climate protection is characteristic of their approach.
