Britain’s canals and rivers are reportedly facing serious financial challenges and increasing pressures from climate change, as highlighted by campaigners from the Inland Waterways Association (IWA). The IWA indicates that approximately 75% of the nation’s waterways are at risk due to funding shortfalls, particularly as the country anticipates heavier winter rainfall and worsening summer droughts.
The IWA has released a climate risk map that estimates that 99% of navigable waterways will be under greater threat in a projected scenario of 2C global warming. Areas identified as vulnerable include the Pennines and the Midlands, where higher-altitude reservoirs supply several canal systems and where drought conditions are expected to escalate. Such conditions have previously led to the temporary closure of sections of the Leeds and Liverpool Canal due to low water levels.
The Canal & River Trust (CRT) states that waterways offer free public access to nature for over 10 million people, contribute an estimated £1.5 billion in annual savings for the NHS, and support more than 80,000 jobs. The CRT manages about 2,000 miles of waterways, accounting for roughly 80% of Britain’s navigable canals.
A notable incident occurred earlier this year when the Bridgewater Canal embankment at Dunham Massey collapsed, illustrating the vulnerability of the infrastructure. Despite maintenance, heavy rainfall caused significant damage, resulting in considerable emergency costs and evacuations.
The CRT receives government funding to assist with infrastructure maintenance but indicates that current financial support is not sufficient to maintain the network. The organization emphasized the financial impact of emergency repairs, which totaled £10 million last winter due to extreme weather events.
The IWA is advocating for a government review to establish sustainable, long-term funding for waterways. They urge that increased funding could strengthen infrastructure, mitigate flood risks, and support strategies for water management, ultimately protecting the economic and environmental benefits of the waterways.
