Cradle to Cradle, en wat (ecologische) duurzaamheid nog meer is Prof.dr.ir. Taeke M. de Jong Almere 20071021
Levels of scale to be aware of • Different levels of scale mean different legend units, categories, views, approaches, conclusions
For example: 4 usual scenarios Scale? Culture? Technology? Ecology? Space?
Questionnaire of futures • Field of problems = Probable - Desirable • Field of aims = Desirable - Probable
Dutch cradle to craft Journals28 October 2007 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

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.
