Green space

Green space (or greenspace) is an area of vegetated land (grass, trees, shrubs, etc.) within an urban context, i.e. the countryside is generally not considered to be greenspace.

Green space is often set apart for recreational or aesthetic purposes to break up and provide contrast to the built environment.

Typical examples of green space include:

Green spaces play an important role in an urban ‘ecosystem’, providing a place for physical activity, relaxation, social interaction, community events, and so on. In high-density urban areas, or areas with a high concentration of traffic, green spaces can provide a place that is relatively free from air and noise pollution.

Access to green spaces is considered important for mental health and wellbeing. The World Health Organisation (WHO) has highlighted analysis suggesting that physical activity in a natural environment can help alleviate mild depression and reduce physiological stress indicators.

Green spaces, particularly those with water features, can also play a critical role in cooling cities, particularly mitigating the urban heat island effect (UHI), which is primarily caused by the replacement of natural surfaces with hard impervious surfaces that are generally dark and absorb large amounts of solar radiation. This has a significant impact on thermal comfort in city environments.

Landscape urbanism is the theory of urban planning through the medium of landscape. It promotes the general idea that cities are best planned and organised, not through building and infrastructure design, but through the design of landscape.

NB The green belt establishes a buffer zone between urban and rural land, separating town and country and preserving land for forestry, agriculture and wildlife where environmental conditions can be improved and conservation encouraged.
