Abstract title


The pesticide-free cities trend : creative ways to healthier landscapes




Most cities face environmental issues that are both complex and hard struggle. Locally, green space managers can play a positive role to spare and enhance biodiversity and public health.

Over the last 15 years, consideration to stop pesticide use in public space has spread among french cities. Pionneers faced many challenges to make this idea a reality. To get rid of these strong habits, cities have worked on alternatives and biocontrol solutions. Many research supported this trend. But after so many years with “zero weed” as a standard, the main challenge was, and still is, social acceptance of unwanted plants. Hundreds of cities experiences taught us that the change of perception is a key for long term effects.

These new sustainable practices have other benefits. Cities stakeholders must re-design public space to consider ecological services and to offer inhabitants a new urbanism from “parks in city” to “city within parks”.
