FAIRE URBAN ECOSYSTEMS
This project has been realized for the call for ideas FAIRE organized by Paris municipality in collaboration with Perrine Frick, landscape architect, same architectes and boum boum, a collective that take care of building non standard architectures.
This project starts with two observations :
Ecological finiteness: planetary biomass exists in finite quantity. Man must be responsible for the good management of this biomass. In large cities, massive concreting, deterioration of air quality and soil depletion make it difficult for trees to grow in urban areas, even in the open. This observation imposes a reintegration of the green fabric in the city in other forms than that of the classical park.
The need to integrate the notion of progress at each stage of a recycling process to improve our environment in a very long-term circular economy approach.
Parisian trees are grown in an extra-mural nursery for an average of 8 to 10 years. The goal of the Paris City Hall is to plant 20,000 trees by 2020.
A tree produces between 6 and 20 tons of oxygen a year, 15 to 30 kg of which is surplus and fixes 4 to 5 tons of CO2 per year. The average oxygen consumption of an adult person equals the surplus produced by 10 trees in one year. Installing a large nursery in situ in the neighborhoods that have the least access to woodlands would significantly increase the quality of life in these neighborhoods.
Our long-term vision is to provide Paris with a new green lung whose implementation will follow a process of conception and realization of a new kind. A diffuse park such as a large urban nursery that provides areas of well-being throughout the growth of the plants that compose it; and whose mature organic matter can be used to design a sustainable public space project, a new large metropolitan park. The establishment of these ecosystems can be progressive and didactic, each new ecosystem is an event.
