ABSTRACT
Good quality greenspace plays a vital role in enhancing the quality of urban life. In many cities the quality of greenspace declined during the second half of the twentieth century. After 2000, greater emphasis on the role of open air recreation in improving health and the role of green areas in adapting to climate change led to signs of improvement in some countries. The emphasis on biodiversity in urban areas, green infrastructure and blue-green corridors are changing the faces of cities from Riyadh to Murmansk and Los Angeles to Shanghai. Urban greening is a vibrant reality, but there remains a great deal to be done to make that urban greening accessible to all city dwellers. Urban greening: In the sense of urban ecology generally, urban greening is an integrated approach to the planting, care and management of all vegetation in cities, towns, townships and informal settlements in urban and peri-urban areas.
