The conference which will hear from leading thinkers in the sector including Professor John Handley, Professor Chris Baines and designer Chris Beardshaw, and will be hosted by BBC's Mark Easton, aims to "explore the models, networks and alliances" that will be needed "to keep the green spaces in all communities thriving, productive and accessible", organiser Groundwork said.
Noting the progress that has been made in the past three decades in terms of understanding the benefits of connecting people with nature and how ecosystem services underpin our economy, organisers warn there is now a risk of that progress being eroded as progressive cuts in public spending bite.
"Our challenge is to find new arguments to justify investment and new ways of getting things done," said Groundwork.
As well as Groundwork, the conference is also supported by Manchester City Council, Keep Britain Tidy, the Federation of City Farms and Community Gardens, the Land Trust and Marks & Spencer and was inspired by John Davidson, the founder of the Groundwork movement who died earlier this year.
