Sarah Johnson, community development officer, London Borough of Hammersmith and Fulham "I am responsible for Normand Park, which received £3m in investment from the local authority. I'm trying to get a diverse range of users in the park so that everyone feels safe and enjoys it.
"We work closely with the local New Deal for Communities and we are piloting a green dog-walkers scheme, which involves a pledge to clean up after their dogs. We also look at diversionary activities such as sporting days."
Agnes Knoll, community gardener, Bankside Open Spaces Trust "There's a distinction between inappropriate play and antisocial behaviour, but some things look intimidating. We've been involving young people in volunteering and created extra activities for youths.
"It is early to say whether it's had an effect, but I believe it can help with public perception. When residents see young people looking after a green space, it might help them see they are not doing anything wrong. Partnerships with other groups are also important."
Tim Douglas, culture and leisure services policy and performance officer, Hounslow Council "When we look at developing parks, we try to do so in a way that minimises crime. This involves working with local police, which means they can feed in with statistics that help us work out how to best deal with problems in a targeted way.
"It is also key to work with the community. It is all about partnership and involving the right people. Working with a landscape architect at the design stage to integrate issues is also important."
Richard Gentry, constabulary and support manager, City of London "We are unusual because we have very different parks and open spaces, so we have to take different approaches. Hampstead Heath has more than five million visitors a year and we employ our own constables.
"We have a good relationship with the Met Police. We have been involved in initiatives with Camden Council, particularly on dogs. We work with the police on robbery and hope to work with Camden Lesbian, Gay, Bisexual & Transgender Forum on sexual litter."
