La ZAN negotiates its landing in the territories, and it’s complicated. ZAN is the small name of “Zero net artificialisation”, introduced by the Climate and Resilience Law in the Town Planning Code a little over a year ago. At the moment, it occupies the days and haunts the nights of local elected officials and city manufacturing professionals.
Because yes, the ZAN poses several problems. the ” Zero “ first of all. The device bets on the collaboration of local actors to intelligently share an effort to divide by two the surfaces consumed to enlarge our cities. As much to say it frankly, nothing is won.
Some territories have created real collaboration practices in recent years, and are currently undertaking this difficult negotiation exercise. But others are going to apply the runoff theory to urban planning, and decline in an absurd way the rate of -50% on a municipal scale which no longer bears any relation to contemporary urban issues. But the A, for “artificialization”is also problematic.
Where and how to make the city?
Not only is the term unpronounceable – parliamentary debates have clearly demonstrated this – but the law and its decrees have still not allowed us to understand what it really means. In the minds two questions are mixed up in a confused way. On the one hand, “Where to do the city? »associated with the consumption of agricultural or natural spaces to develop new urban spaces, land, the long term, and planning documents.
The other, “How to make the city? », related to soils, their ecosystem functions, short time and operational town planning. The controversy will still go on before we share the same vision and manage to write texts that reach consensus, and that’s good: we haven’t had such rich debates on the making of the city for two good decades. .
stay the “clean”, with the idea that the artificialization of the soil could be compensated, but without us really knowing how. That’s a lot of trouble for a three-letter acronym, but if it were just that, it wouldn’t be so bad. Because by targeting the artificialization of the soil, the law has taken the wrong target: this “Zero artificialization” is only the symptom of a much deeper evil.
For half a century, agricultural soils have become the raw material of a model of urban development in impasse, based on automobile monoculture, the separation of functions and a handful of standardized real estate products.
