When you walk through your local park or along the pavement, you might not think much about how the weeds are kept under control. But behind the scenes, councils across the country are rethinking their approach, moving away from chemical pesticides and exploring greener alternatives.
This shift is part of a national effort. The UK Pesticides National Action Plan sets out how we're working to minimise reliance on chemical pesticides across the board, including in our public spaces. This approach is called Integrated Weed Management, and it's all about finding smarter, more sustainable ways to look after our green spaces.
Learning from Cambridge Council
Last month, Emma Hardy MP, Minister for Water and Flooding, visited Cambridge City Council to see how pesticide use was being reduced and more sustainable approaches to weed management.
Cambridge has been on this journey since 2019, when the council declared a Biodiversity Emergency. Since then, they've been working to cut herbicide use on highway verges, pavements and public spaces, testing out different methods to see what works best.
During her visit, the Minister saw some of these techniques first-hand, including mechanical, thermal and hot water methods, alongside discussions of trial results, operational learning, and challenges involved in moving away from herbicides.

This was alongside community groups such as Pesticide Free Cambridge and On the Verge Cambridge, who offered their perspective on how local people can play a part.
Julia Shaw and Ben Greig, the founding members of these organisations, have been working collaboratively with Cambridge City Council, community groups, schools, businesses and local residents to drive various local pesticide-free campaigns. This includes the Happy Bee street scheme, a community initiative where local residents get involved with weeding in their neighbourhoods without the use of pesticides.
The council provides tools, equipment, advice on planting and training for volunteers who apply in groups. The scheme has helped pollinators like bees survive, reduced chemical use and encouraged greener streets while building community involvement.
Why community involvement matters
One of the key takeaways from Cambridge's experience is just how important local knowledge and public engagement are. Every community is different, and what works in one area might not suit another.
There's also a balance to strike. We want to encourage biodiversity and protect the environment, but we also need to make sure our public spaces are safe, accessible and well maintained.
Getting that balance right takes collaboration between councils and the people who use these spaces every day.
