Urban green spaces are important in cities due to the opportunities they provide to people to come in contact with nature and with each other. Contact with nature has psychological benefits by reducing stress restoring attention , reducing criminal and anti-social behaviour and by positively affecting self-regulation and restorative experiences. In addition to psychological benefits from contact with nature, there are direct physical health benefits such as addressing issues associated with obesity , increased longevity and self-reported health . In terms of social well- being urban green space contributes to social interaction and to bringing people together, reduces negative social behaviours such as aggression and violence, contributes to a sense of place and plays an important role in fostering social cohesion and identify. These psychological, physical and social health effects of urban green spaces make them an important component of public health provision
However, green spaces that are perceived to be unmanaged may have a negative effect on the well- being of people by increasing anxiety caused by crime and fear of crime . The occurrence of wild animals in cities, for example, large mammals such as fox , badger wild boar and bear , bring with them a need to address the changing relationships between people and wildlife. Urban and peri-urban ecological changes can affect the geographical range of diseases such as Lyme disease and West Nile Virus. Hence, further research will show whether it is possible to quantify environmental influences and subsequent positive or negative health outcomes from different types and configurations of urban green spaces.
