The contributions of forests, trees and other urban green areas to the quality of urban life and the environment can be significant. When existing good practices are built upon, urban forestry has shown significant contributions to the quality of urban life and the environment, together with other types of comprehensive green-space planning and management concepts. Through agroforestry systems, for example, urban forestry and urban agriculture join forces in supporting livelihoods. A review of the current status of urban forestry research and development, policy-making, implementation and education across the globe shows that advances have indeed been made. Urban forestry has been developed in response to the call for innovative, comprehensive concepts that promote the multiple benefits of urban green space. Sometimes named urban and peri-urban forestry, the concept encompasses the planning and management of forests and other tree resources in and close to urban areas and thus integrates different parts of urban green structures.
