6 Urban Green as an amenity: Accessibility urban green spacessettlement area  Our research approach focuses on the accessibility of urban green spaces (in terms of “green infrastructure”).  This is hardly displayed only by the pure amount of green spaces.  Idea: settlement area within a 300m radius („as the crow flies“) around urban green spaces total urban settlement area „Greenness“ = 6

7 Urban Greenness = 84,2 % Urban Greenness – GIS approach 7

11 11 Input-Output Tables: Basis of analyses Source: Wang et.al (2006)  Input-Output-tables are a statistical tool to show the complex interrelations between economic sectors.  For each value in output the table lists the amount of input needed from each relevant sector. selling to buying from

12 12 Input-Output Tables: Rationale of economic Stimulus 1 direct effect 2 indirect effect 3 induced effect Regional Economy 1. Investments bring external money into the regional economy. Contractors are paid for their work (direct effect). 2. To do their work, contractors need to buy intermediate goods and pay their employees (indirect effect). 3. Employees spend their income for consumption goods (induced effect). 4. An iterative, but diminishing circle continues.

13 The VALUE investments Bruges - Land Use Plan “A Green Cycle Belt for Bruges” 2. Verviers - Terraces of “Grandes Rames” Street and “Marie- Henriette” Park 3. Sheffield - The Wicker, Urban Green Improvements 4. Manchester - Whithworth Street West Tree Planting 5. Esslingen - Cycle and Pedestrian Path along the Neckar River

16 Conclusions Quality of Life:  Urban greenness has a significant and positive impact on urban Quality of Life.  People value green open spaces as an urban amenity and they are willing to pay for it.  It became also evident, that the pure amount of urban green is not a sufficient measure of peoples’ perception of green infrastructure. Input-Output Analysis:  Investments in green infrastructure show significant stimuli for regional economies.  Every Euro investment induces additional economic activity. 16
