Cradle to Cradle, en wat (ecologische) duurzaamheid nog meer is

Prof.dr.ir. Taeke M. de Jong

Almere 20071021


Lagen in het afwegingskader


Paradox of scale


Levels of scale to be aware of

  • Different levels of scale mean different legend units, categories, views, approaches, conclusions


Contextanalysis


For example: 4 usual scenarios

Scale? Culture? Technology? Ecology? Space?


‘+!’ is only one of 1065 scenarios


Questionnaire of futures

  • Field of problems = Probable - Desirable

  • Field of aims = Desirable - Probable

Advertentietekst:

‘Aan het einde van een lang leven wordt je oude auto vakkundig gedemonteerd. 85% ervan wordt hergebruikt, en binnenkort is datzelfs 95%.

De vulling van de autostoelen wordt opnieuw gebruikt als isolatie en in sportmatten, autoramen en koplampen wordenflessen, en de banden bijvoorbeeld rubberen stoeptegels.

Vandaag recyclen we onze3 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’


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.


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.


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


Rarity and reparabilityevaluating alternatives by space and time


Continental vegetation types

Dutch rarity: water management

Bohn et al.(2001)


Water, secret of Dutch diversity

De Bruin (2007)


Different ecologies involved


Land water gradients R=100m


Land water gradients R=10m


Boundary richness,condition of diversity

Limes convergens, limes divergens, gradient


Ecologicaltolerance


Quality = f(variation)


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 thedistribution and abundanceof organisms, populations and communities.


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


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


The dispersion of two world-wide rare species

marsh fleawort (moerasandijvie)

black-tailed godwit

(grutto)


Autecology: dispersion of one population and its habitat

Gadwall duck

(krakeend)

04 Garland Weed Class (eendekroosklasse)


States of human dispersionon different levels of scale


Principles of urban extension


Built and open space


Interpreting H+N+S Pampus


Interpreting Hosper Pampus


Interpreting TKA Pampus


Interpolating plans to 50 000 inhabitants each(spatial scenarios)

to compare states of dispersion (form)


Open space


Possibilities for nature (H+N+S)


Possibilities for recreation (H+N+S)


Open space first
