London Rivers Week

London Rivers WeekWould you like to become involved in river conservation? Do you understand its importance? Are you looking for an activity that will boost your health and wellbeing? Do you want to take practical steps to combat climate change but don’t know where to start?

Then come and learn how rivers can help YOU as well as London at large, during London Rivers Week 2021, taking place between October 23 and 31. Our list of London Rivers Week 2021 events has something for everyone! 

The Catchment Partnerships in London (CPiL), through the London Rivers Restoration Group, has lined up a fantastic array of events to inspire a love of the capital’s rivers.

Guided walks, talks, practical participation events and online seminars are underpinned by three main themes for the sixth annual London Rivers Week.

This year, there’s also a fabulous chance for budding photographers of all ages and standards to ‘capture the magic of London’s waterscapes’ in a #PictureBlueLondon competition run by CPRE London, the countryside charity. With fabulous prizes to top London attractions, judges will be looking for uplifting images from around the capital in a competition that runs from October 1 to November 26.

The themes for London Rivers Week 2021 are:

  • Access to nature: Demonstrating where you can join in river conservation projects across a wide area. Restored waterways have created more spaces for people – as well as wildlife – to enjoy and thrive.
  • Health and wellbeing: Outling why it is good for you to access blue (and green) spaces, and how different communities appreciate rivers and waterspaces for culural / artistic reasons. Open spaces have been a blessing to many as we emerge from the Covid-19 pandemic.
  • Climate resilience: Showing how river restorations help species and humans cope with extreme weather events, such as drought and flooding, plus pollution, by making them more resilient to possible impacts; joining together fragmented sections of waterways also help species thrive.

Did you know London has 400 miles (about 640km) of waterways – from rivers to wetlands, streams and canals? Since 2000, about 28 miles (45km) has been restored. We’ll be celebrating some of those successes. But CPiL has set the target of raising the rate from about 3km on average per year to 5km by 2025 and beyond. If we did that, we could transform a third of the capital’s waterways by 2050.

London Rivers Week events list 2021Come and learn about rivers! Among our London Rivers Week 2021 events is a chance to educate the family with a visit to a Sewage Treatment Works. Or you explore the wonderful biodiversity of rivers, wetlands and canals from Enfield to the Ravensbourne and across to Dagenham and the Hogsmill, courtesy of our various partner organisations. How about a guided walk along the Illuminated River route of the Thames? Or learning about mudlarking at Southwark Cathedral? And what is the significance of rivers to communities such as those from Africa?

Perhaps you would prefer discussions, seminars and learning opportunities about why the Catchment Partnerships in London carry out river restorations. We’ll be unveiling a map charting future opportunities for river restoration across the capital and outlining why they can help with climate resilience.

If you can’t wait, why not explore some of London’s great blue green spaces by enjoying our self-guided walks that were put together for London Rivers Week 2020?

London has nearly 400 miles of waterway – that’s the same distance as from Brighton to Edinburgh. Over the past 20 years, more than 20 miles has been ‘rewilded’ or restored. Rewilding can involve simple actions such as adding woody material to a river, or removing concrete and metal from its banks. It can also mean giving rivers more space to flood over water meadows, or creating new wetlands beside them. It can even mean daylighting stretches of rivers – bringing buried rivers into the light once more. London has examples of all of these, and you can find them through the map below.

Now in its sixth year, London Rivers Week raises awareness of London’s network of rivers, how they benefit us and how we can protect them. We look forward to seeing you for London Rivers Week 2021!

London Rivers Week is organised for the Catchment Partnerships in London Group (CPiL) by its London Rivers Restoration Group arm. The principal organisations running London Rivers Week are the Environment Agency, Thames21, the South East Rivers Trust, London Wildlife Trust, ZSL, CPRE London, the Thames Estuary Partnership, Berkeley Homes and Thames Water, which also sponsors the week. Many other groups run and contribute to events, walks, talks and seminars to demonstrate the value of rivers.
