Revising Green Infrastructure

Abstract

Throughout the history of urbanism, there has almost always been an interweaving of structures of plantation with urban armatures and tissues. In Europe and Asia, forests have traditionally formed the counter-figure of the city (from Karlsruhe to the Barcelona plan of Cerda-although that plan is usually represented without the unrealized forest), embedded the city (from Versailles to Suzhou), or complemented the city (from Paris to Dalat). In an attempt to locate Islamabad in a "natural environment," its foundation (plan of Doxiadis, 1960) was developed hand in hand with the systematic afforestation of the Margalla Hills, a previously barren mountain chain. In Europe, the Forêt de Soignes in Brussels, Epping Forest in London, Bois de Boulogne or de Vincennes in Paris, and Wiernerwald (Vienna Woods), among others, bear witness to how forests have become an essential identity of the city (Figure 21.1) (Forrest and Konijnendijk 2005). In many parts of Asia, cities historically developed in relation to a worldview that included geomancy (feng shui) and divination, which limited the activities of man; beliefs in land gods, river kings, and forest spirits were both practical and mystical (Cuc 1999;Yu et al. 2006). The central highlands Vietnamese city of Dalat is known as the "city of thousands pine trees" (De Meulder and Shannon 2012), Suzhou, known as "Venice of the East" and famous for its canals and garden, yet it is embedded in an equally awe-inspiring forest setting.

Leveraging the No Net Land Take Policy through Ecological Connectivity Analysis: The Role of Industrial Platforms in Flanders, Belgium

“…The ecological connectivity of the green network (habitat types and size) was analysed using the Patch-Corridor-Matrix (PCM) model [25]. The model allows for identifying and representing landscape elements in a categorical map pattern [26][27][28] and identified three types of landscape elements (see Figure 2): the matrix, the dominant element of a landscape characterised by a certain uniformity of land use; patches, relatively homogeneous areas that differ from their environment; and corridors, strips of a particular kind of habitat that differ from adjacent lands on both sides. A pattern created by overlapping patches, corridors, and a landscape matrix is identified as a mosaic.…”
