The Royal Town Planning Institute defines Green Infrastructure as follows:
“Green infrastructure is a phrase used to describe all green and blue spaces in and around our towns and cities. The term allows us to refer to – and consider the collective value of – all of these spaces at once. Elements of green infrastructure include parks, private gardens, agricultural fields, hedges, trees, woodland, green roofs, green walls, rivers and ponds. The term covers all land containing these features, regardless of its ownership, condition or size.
The term green infrastructure is a description of what the land is, but also reflects what the land does. The emergence of the term green infrastructure was combined with a heightened understanding of the numerous benefits to be gained from providing and maintaining a healthy green infrastructure resource; including reducing flood risk, improving psychological health & well being, boosting local economic regeneration and providing a habitat for wildlife.
In the past, green spaces have often been valued for single uses, such as for sport/recreation, or simply for their aesthetic appeal. The term green infrastructure reflects the fact that green spaces can perform a number of functions, often simultaneously. One site could be providing several
functions at once, providing us with multiple benefits from one site.”
