2 Lagen in het afwegingskader

3 Paradox of scale

4 Levels of scale to be aware of Different levels of scale mean different legend units, categories, views, approaches, conclusions

5 Context analysis

6 For example: 4 usual scenarios Scale? Culture? Technology? Ecology? Space?

7 ‘+!’ is only one of 10 65 scenarios

8 Questionnaire of futures Field of problems = Probable - Desirable Field of aims = Desirable - Probable

9 Journals 28 October 2007 Advertentietekst: ‘Aan het einde van een lang leven wordt je oude auto vakkundig gedemonteerd. 85% ervan wordt hergebruikt, en binnenkort is dat zelfs 95%. De vulling van de autostoelen wordt opnieuw gebruikt als isolatie en in sportmatten, autoramen en koplampen worden flessen, en de banden bijvoorbeeld rubberen stoeptegels. Vandaag recyclen we onze 3 miljoenste auto. Daar kunnen we met z’n allen trots op zijn! De autobranche zegt wel eens: ‘Was iedereen maar zo netjes op het milieu.’ Auto Recycling Nederland is een onderneming van BOVAG, FOCWA, RAI en STIBA. www.arn.nl, email: info@arn.nl’ Dutch cradle to craft

10 Cradle to cradle extending R=1m From recycling into upgrading beforehand Leaving more possibilities Choice for future generations supposes –not only our choice. Freedom of choice supposes –diversity, opportunity to choose (risk cover for life) ; –health, ability to choose.

11 Declining biodiversity and health No other environmental problems –even energy is no durable problem if it does not affect biodiversity or health at last –solar power = 6000 x current human use of energy after all. Complex on itself –local, regional, continental or global diversity? –within a year, a decade, a century? –the same applies for health.

12 Rarity measures the uniqueness of location drives evolution, biodiversity, surprise motivates technical innovation determines economic scarcity, value determines cultural identity, pride touches the electorate of governance touches all layers

13 Rarity and reparability evaluating alternatives by space and time

14 Continental vegetation types Bohn et al.(2001) Dutch rarity: water management

15 Water, secret of Dutch diversity De Bruin (2007)

16 Different ecologies involved

17 Land water gradients R=100m

18 Land water gradients R=10m

19 Boundary richness, condition of diversity Limes convergens, limes divergens, gradient

20 Ecological tolerance

21 Quality = f(variation)

22 The ecologist’s view Andrewartha (1961):Ecology is the scientific study of the distribution and abundance of organisms. Krebs, C.J. (1972, 1992): Ecology is the scientific study of the the interactions that determine the distribution and abundance of organisms. Begon; Harper; Townsend (1996): Ecology is the scientific study of the the interactions that determine the distribution and abundance of organisms, populations and communities.

23 The designer’s view: state of distribution(form)

24 Alternatives of form: states of dispersion on one level of scale

25 The dispersion of two world- wide rare species black-tailed godwit (grutto) marsh fleawort (moerasandijvie)

26 Autecology: dispersion of one population and its habitat Gadwall duck (krakeend) 04 Garland Weed Class (eendekroosklasse)

27 States of human dispersion on different levels of scale

28 Principles of urban extension

29 Built and open space

30 Interpreting H+N+S Pampus

31 Interpreting Hosper Pampus

32 Interpreting TKA Pampus

33 Interpolating plans to 50 000 inhabitants each (spatial scenarios) to compare states of dispersion (form)

34 Open space

35 Possibilities for nature (H+N+S)

36 Possibilities for recreation (H+N+S)

37 Open space first
