Green infrastructure for cities: the spatial dimension. In (2007)

by J. Ahern


Summary: Planning for sustainable cities is a complex process addressing the fundamental areas of economic, environmental and socially-equitable sustainability. This chapter focuses on the environmental area, with theories, models, and applica-tions illustrating possible spatial configurations of a green infrastructure to support ecological and physical processes in the built environment including: hydrology, bio-diversity, and cultural/human activities. Green infrastructure is an emerging planning and design concept that is principally structured by a hybrid hydrological/drainage network, complementing and linking relict green areas with built infrastructure that provides ecological functions. Green infrastructure plans apply key principles of landscape ecology to urban environments, specifically: a multi-scale approach with explicit attention to pattern:process relationships, and an emphasis on connectivity. The chapter provides theoretical models and guidelines for understanding and com-paring green infrastructure approaches. International examples at multiple scales are discussed to illustrate the concepts and principles introduced.
