[ B 1,1] [ ⋇ ] Ecopolis isn’t a brand, it’s a theoretical position

Ecopolis appears to be just another word for ecocity, but it harbours some profound, albeit subtle, differences. Simply put, the concept of ecopolis (that I favour and have promoted publicly since 1989) is broadly shared by Russian, Chinese, Italian, and other European researchers and protagonists and refers to a “city plus its region”. Thus, an ecopolis is not just bricks-and-mortar, steel, glass, and concrete, but includes its essential hinterland. Its ideal model would be that of urban systems embedded in their bioregion in an interdependent relationship.
From “eco”, to do with ecology and “polis”, a self-governing city, I take ecopolis to mean city plus region (like Magnaghi and Wang) but that clearly isn’t the definition adopted by Vincent Callenbaut who would have well-heeled “climate refugees” living on self-contained, hi-tech ocean-roaming Lilypads each claiming to be an “ecopolis”. Register prefers ecocity to ecopolis, arguing that as a word it is more readily understood (and is easier to render in the plural). To include the region, he favours “ecotropolis”. But we’re all trying to say pretty much the same thing.
