THE EUROPEAN CITY DOES NOT HAVE ONE NATURE: THERMAL FIELDS, ECOLOGICAL SCALES, HEALTH EFFECTS AND PLANNING DEVICES IN MADRID, ROME, PARIS, BERLIN, LONDON AND OSLO · LAPIEZA LAB · ANTO LLOVERAS · SOCIOPLASTICS · 2026

European metropolitan nature becomes legible only when the category “green space” is broken into the spatial, ecological, social and institutional relations that make environmental capacity operative. The ten studies assembled across Madrid, Rome, Paris, Berlin, London and Oslo do not converge on a universal green metric; they progressively dismantle one. Madrid first shows that landscape performance exceeds cadastral boundaries. Aram and colleagues measure the cooling influence of a 125-hectare urban park through mobile observations and perceived thermal comfort, demonstrating that distance from the park is associated with changes in air temperature, physiological equivalent temperature and bodily perception. The park is therefore a thermal field rather than an isolated polygon.
