• National Planning Policy Guidance 17: Planning for Open Space, Sport and Recreation (2002) identifies the contribution of open spaces, sport and recreation to people’s quality of life. Green spaces in urban areas perform vital functions as areas for nature conservation and biodiversity. By acting as ‘green lungs’ they can assist in meeting objectives to improve air quality. Well planned and maintained open spaces and good quality sports and recreational facilities can play a major part in improving people’s sense of well being in the place they live. As a focal point for community activities, they can provide opportunities for people to socially interact. Open spaces, sports and recreational facilities have a vital role to play in promoting healthy living and preventing illness, and in the social development of children of all ages through play, sporting activities and interaction with others.
