METABOLISM AS PLANNING PRINCIPLE<br />

<strong>The</strong> ambitions <strong>of</strong> <strong>the</strong> territory are realised to <strong>the</strong> full when <strong>the</strong> systems <strong>of</strong><br />

agriculture, habitation, industry, nature, recreation etc. that lie alongside and<br />

superimposed on one ano<strong>the</strong>r start to cooperate and interact. Ra<strong>the</strong>r than<br />

simply creating a place for burgeoning collectivity, territorial collectivity in this<br />

instance organises itself around <strong>the</strong> sharing <strong>of</strong> services and amenities. This<br />

collective organisation thus shares <strong>the</strong> territory and organises its evolution and<br />

transformation towards a more sustainable state. If an agricultural activity<br />

produces surplus energy and is located alongside a residential community, this<br />

may be a reason to bring about greater efficiency by linking <strong>the</strong> two uses <strong>of</strong> space<br />

toge<strong>the</strong>r. Residual heat can be used for <strong>the</strong> surroun<strong>di</strong>ng housing so that <strong>the</strong> two are<br />

more closely connected to each o<strong>the</strong>r. <strong>The</strong> exchange <strong>of</strong> interests means that mutual<br />

win-win situations—or productive relationships—determine <strong>the</strong> organisation <strong>of</strong> space.<br />

Connecting society to <strong>the</strong> territory in a single spatial metabolism gives rise to<br />

a new logic for (spatial) organisation and planning. <strong>The</strong> work done by GRAU and<br />

Atelier Versailles takes <strong>the</strong> juxtaposition <strong>of</strong> landscape functions and urbanisation<br />

one step fur<strong>the</strong>r: <strong>the</strong> productive combinations between <strong>the</strong> elements <strong>of</strong> <strong>the</strong> territory<br />

help define <strong>the</strong> structure for future urbanisation. And no longer <strong>the</strong> o<strong>the</strong>r way<br />

around. For example, GRAU identifies those locations where industrial activity<br />

produces surplus heat and energy as <strong>the</strong> ideal places to set up new, energyintensive<br />

agricultural activity. Or else, on <strong>the</strong> basis <strong>of</strong> <strong>the</strong> essential intensification<br />

and increase in scale <strong>of</strong> glasshouse cultivation, <strong>the</strong>y present a vision <strong>of</strong> <strong>the</strong> structure<br />

<strong>of</strong> <strong>the</strong> residential fabric around <strong>the</strong> water, heat, and electricity networks. <strong>The</strong> sharing<br />

<strong>of</strong> energy (passing on superfluous energy), <strong>the</strong> reuse <strong>of</strong> water (consumption and<br />

reconsumption), or <strong>the</strong> recovery <strong>of</strong> heat (emission and reuse) give rise to a gui<strong>di</strong>ng<br />

principle for siting future programmes and functions in <strong>the</strong> most suitable locations.<br />

TOWARDS METROPOLITAN AND PRODUCTIVE TERRITORIES<br />

This is precisely what is being explored in <strong>the</strong> work done on <strong>the</strong> central part<br />

<strong>of</strong> Flanders between Antwerp and Brussels. This area is subject to <strong>the</strong> greatest<br />

pressure from urbanisation: rising land prices and <strong>the</strong> increasing demand for<br />

recreational landscapes are putting huge pressure on agriculture. In a strategy<br />

that GRAU developed in cooperation with <strong>the</strong> Boerenbond (Farmer’s Association),<br />

<strong>the</strong> various challenges are linked toge<strong>the</strong>r. <strong>The</strong> proposed landscape lobes in <strong>the</strong><br />

o<strong>the</strong>rwise urbanised territory will function as productive parks that accommodate<br />

agrarian and recreational activities. In this way <strong>the</strong> open space provides essential<br />

(life) services to urban society. Instead <strong>of</strong> opting for a defensive protection <strong>of</strong> <strong>the</strong><br />

open space in <strong>the</strong> face <strong>of</strong> advancing urbanisation, <strong>the</strong> strategy goes for protection<br />

by development: <strong>the</strong> organisation and productivity <strong>of</strong> <strong>the</strong> unbuilt space gives<br />

structure to future urbanisation. <strong>The</strong> landscape becomes productive in two ways:<br />

as a producer <strong>of</strong> services that enables urban society to survive, and as an organising<br />

system for its fur<strong>the</strong>r development towards a metropolitan territory.<br />
