  1. 1. 5/8/2010 OutlineUrban Harvesting as planning approach Problem definitiontowards productive urban regions Concepts:Wouter LeducLandscape Architecture and Urban Environmental Management and Technology Urban metabolismGroup – Wageningen University Industrial Ecology – industrial ecosystemFerry Van KannFaculty of Spatial Sciences – University of Groningen Urban harvest approach SCUPAD 2010, May 7 Low-exergy Planning 7-step method and results (case Kerkrade-West) ConclusionsProblem definition Aim Growing urbanization increasing pressure on available resources Waste production To develop method for an urban metabolism conscious spatial planning, emphasizing on Cities disconnected from sources distances do not energy, towards productive urban regions matter (fossil fuel based system) Lack of integration between urban planning & resources management 1
  2. 2. 5/8/2010Urban Metabolism Industrial ecology Industrial system in which consumption is optimized; waste minimized; effluents serve as raw materialLinear Harvesting of water, wind and energy Ecosystems principles apply: Roundput: recycling & cascadingNon-renewable energy, water, materials Emissions to soil, water and air Reused and recycled waste Diversity: in actors, in inter-dependency and co- materials, gases and liquids operation Locality: use local resources, respect local limiting factors Urban Harvest Gradual change: evolution, transition to sustainable Sources-and-sinks Circular system, no sudden change/shockUrban Harvest Low-exergy planning Capture all renewable and residual primary and Multi-functional land-use & multi-functional structures secondary resources Each flow has a remaining quality credit: no waste, Connectivity & proximity only resources in different qualities Aim to use, re-use, re-cycle Distances Closed cycle resource management Densities System sizes Valid for the different urban flows 2

Inventory of spatial functions and land-use distribution 2. Identify large consumers of energy 3. Inventory of existing energy demand and categorize (quality and quantity) & identify local energy potential 4. Identify and localize clusters 5. Identify energetic linkages and missing links 6. Connect clusters and explore network patterns 7. Develop smart spatial policies 4
