he United Nations’ Johannesburg summit (2002) report, Agenda 21, calls for a philosophy of ‘integration of the environment and ecosystems on which we depend for our wellbeing’. Here in the UK, a report by the government agency English Nature (2003) asserts that measures of the impact of nature on the psychological and social wellbeing of people can be derived from a multitude of ‘social, community involvement and environmental indicators’. The Social Exclusion Unit (2004), the Department for Work and Pensions (2004) and the Neighbourhood Renewal Unit (2004) are all embarking on programmes to create opportunities for social networks and the employment of people with mental health problems. The Forestry Commission and the Urban Parks Forum are engaged in the regeneration of open spaces and public parks for the promotion of sustainable communities that are ‘fully inclusive and cut to the core of social exclusion and poverty’. The international conference Open Space, People Space, hosted by the Research Centre at Heriot-Watt University in October 2004 brought together researchers, organisations, individuals and academics from all over the world to discuss and share the practice and research taking place in the many strands of this rapidly evolving field. English Nature indicates that policies such as the National Service Framework for Mental Health (Department of Health, 1999) and the National Suicide Prevention Strategy (Department of Health, 2002) or initiatives such as From Here to Equality from NIMHE (2004) do not yet address the health-promoting benefits inherent in nature. Likewise the agencies involved with environmental sustainability and biodiversity ‘have not yet identified the purely mental health promoting elements of access to nature in urban, semi-urban and rural settings’. Social inclusion and psychological and physical wellbeing can be harnessed in natural settings and English Nature T recommends that social policy discourse needs to change towards the recognition that healthy people and healthy ecosystems are wholly interdependent. This change would derive from and be supported by three main areas of activity:
