New EIVP / ECT symposium: “Urban soils: positive values for the city of tomorrow”.
On June 22 and 23, the Ecole des Ingénieurs de la Ville de Paris (EIVP) and ECT organized the “Valorisation des terres issues des chantiers urbains” chair, in partnership with L’Ecole Nationale Supérieure de Paysage de Versailles (ENSP) and with the participation of Cycle Terre, a new symposium. An opportunity for ECT and EIVP to explore and share ideas that place land at the heart of current debates on the sustainable city in a number of ways:- a vector for rehabilitating neglected sites, a structuring element for the new territorial landscape,
- environmentally-friendly building material
- an essential element in the urban integration of green spaces and biodiversity.
A multidisciplinary approach to sustainable urban development
These different focuses suggested that urban land could be a new, positive approach. They are an integral part of sustainable city policies. Through a dual approach of saving resources and reusing environmentally-friendly materials. This was illustrated by a wide variety of theoretical and historical examples and approaches, as well as international, national and Ile-de-France examples.
These four half-day sessions argued in favor of developing a multi-disciplinary approach to urban engineering, ecological engineering, urban planning and landscaping.
