GREEN FLOWS
Un nuovo modo di vivere la cittĂ A new way of living the city
Why biodiversity? What is hidden behind this word? How the future of the city can be involved in biodiversity issue? Why do we need a bio-city? What does it mean rethinking the relationship between ani- mals and men?
to the hu- man control, by leaving the marginal areas what is no more controlled by humans, like abandoned fields, buildings and undiscovered green areas unknown by the citizens. Dealing with a non-antrophocentric approach, the point is to enlarge the way of acting, in order to provide a new way of living in which mankind is no longer alone, but placed in a more complex and wide scenario, made by nature and animals too. At such a point the statement of Gilles ClĂŠment, regarding the Third landscape, was quite interesting for us. In this little book by the landscapist of the Ecole Nationale SuperiĂŠure pour le Paysage in Ver- sailles, plants, as nature device of expression and animal material, are real aids to observation, visibly showing change and serving as prompts for reflections on the landscape, actions and aesthetics. From this starting point the Third landscape, nei-
If on the one hand the Eden myth offers a clear idea of a communal life between men, animals and nature, on the other hand reality se- ems to be far away from natural world, not just as a matter of fact, but also as a matter of ethical background, and as a practical way of building the city of the future. Looking at the city of Milan, we often see a huge gap between the internal areas of the city, mostly characterized by a dense urban fa- bric, with little glimpses of green, and external areas full of big green spaces and agricultural fields, not always controlled by men. The ten- dency in our metropolitan cities is to undergo everything

ther a never exploited spa- ce, nor protected by human activity, become a place of refuge for na- tural bio-diversity: compared to the territories submitted to the con- trol and exploitation by man, the Third Landscape forms a privileged area of receptivity to biological diversity. In this sense it was useful for us to notice how biodiversitity, in its larger meaning , is autono- mous in its being and growing, without the need of human control. Those reflections led us to think about which degree of control human should have on animals and on their natural environment.
with the necessity of rebuilding the relationship between man and the natural world. By reversing this relation we want to let nature recapture this space,making men aware of the existence of different ecosystems in the world: not just those created by human for human, but those created by nature for animals too. Our vision of this green river would be to mix different kind of flows within the urban context, hosting different kind of floral and animal species as well as allowing the movement of humans among it. In this new kind of space, there’s gonna be a new dimension of urbanity lived both by humans and animals: we are letting a possibility for biodiversity to populate the city in order to enrich the environment and the urban landscape as we know it today; providing the land on which it can establish and build its own shelters.
Due to those reasons, our purpose was mainly focused on providing a new kind of connection between different areas of the city, using the power of water in Navigli. In particular the aim was to push towards the re-naturalisation of this anthropized part of the city , used just as a landmark of its old function as navigable place. What comes out is a new “green river� made by ecosystems into the city, able to connect different parts of the city, from the outer one of Parco Agricolo Sud, through the city centre of Milan ( the current cove- red part), till Naviglio of Martesana: from a monumental and human insfrastructure to a green infrastructure which allows the movement of species in the city.
This new ecosystem provides for humans the possibility to feel and experience biodiversity: to feel the natural world and all its species, to experience a new kind of landscape by walking through it ( Francesco careri, Walk- scapes). In order to enforce the natural settlement of biodiversity and increase its interaction within the urban context by using the canal and its surroundings, the project is going to exploit some abandoned buildings as well as refunction some industrial ones. These points can be considered like a nature reserve that allow nature to control also the most anthropocentric product of man intelligence: a building.
If - until now - this kind of linear space, characterized by the water flow, has been a typical anthropized one, it will become a sperimental space for the co-habitation of different species,

CARNET DU VOYAGE
From the outside to the inside
From the investigation to the study: six topics
Our concept deals with the theme of flows in the city of Milan. Why? Since our animals can mostly be founded in the external part of the city, in those big parks, rivers and ponds that provide the right environment for them, our aim is to bring them to the city by creating the right path which allows their movement into it. Because of this we chose the Navigli system, an old water system that is connected to the Ticino river as regars the east part of the city, and that brings water to Milan. In particular we decided to have the first survey among the Naviglio Pavese because it shows immediately how the city chenges from the ouside to the inside, from the outer part of the city, full of abandoned places, farmers, fields, wild vegetation or factories, till the inner part of the city, where you perceive
the change in section, activities, and in the all natural system. The investigation led us to focus on six main themes we are going to work on: water flow, vegetation, human activities, inter-sections, shelter and rest. So what about animals? They can only move when they have small places to rest, where to find protection and food. They only move when they feel safe to face this flow into the city. That’s way we called it Rest in Flows. The main purpose is to built artificial stations furnished with different kind of vegetation able to provide food and shelter as well as using built part of the canal like bridges in order to provide rest for both human and animals. This could be a way for a future coexistance between them. In this way animals own a part of the city: water means street, station means home.

CANALS NETWORK IS STAGNATING AND OVERTAKEN BY RAILWAYS
1929-1930 Coverage of canals After railways, cars have begun biggest concurrent of transportation by water. Navigli was abandoned. Most of them were covered in the town like the Cerchia dei Navigli in 1929. The general disinterest of citizens approves a period where towns were dominated by the use of the automobile. Nowadays, some projects are in process for the reopening of underground Navigli.

Biodiversity Engineered wetlands are artificial wetlands, marsh or swamps created as new restored habitat for native and migratory wildlife. Additionally they are suitable for anthropogenic discharge such as wastewaterm stormwater runoff, or sewage treatment: Natural wetlands act as a biofilter, removing sediments and pollutants such as heavy metals from the water, and constructed wetlands can be designed to emulate these features.

Biological Infrastructure The navigli will be straightened out, and there is grass lawns in the area. We propose to re-establish the natural conditions of nature river, creating a biodiversity flow crossing urban Milan. The flow could not only become a constructed piece of real of nature with wetlands and shallow match attracting different birds and other animals to the surrounding greens, but also be developed as green bank in first row towards the nature.

ECOS YSTEM
INFORMATION
CHARACTERISTICS
the cultivation of animals, plants, fungi, and other life forms for food, fiber, biofuel, medicinal and other products used to sustain and enhance human life. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization MAIN VEGETATION spiraea arguta, cotoreaster saliciflia
AGRICULTURAL FIELD
CHARACTERISTICS
One of the most important features of ponds is the presence of standing water, which provides habitat for wetland plants and animals. Often, the pond is fringed by wetland, and these wetlands support the aquatic food web, provide shelter for wildlife, and stabilize the shore of the pond. Ponds often have a large number of different animal species using the wide array of food sources. MAIN VEGETATION : water-lilies, lotus plants, floating plants, submerged aquatic ANIMALS: frogs, turtles, herons, fish, dragonflies, amphibians
POND
CHARACTERISTICS
Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important natural biofilters, protecting aquatic environments from excessive sedimentation, polluted surface runoff and erosion. They supply shelter and food for many aquatic animals and shade that is an important part of stream temperature regulation. MAIN VEGETATION : Thuja plicata, Abies grandis, Salix lasiolepis, Alnus rubra, Populus fremontii ANIMALS: Aquatic animals, frogs, turtles, herons, fish
RIPARIAN WETLANDS
CHARACTERISTICS
Rocky shores are biologically rich environments, and are a useful “natural laboratory� for studying intertidal ecology and other biological processes. Due to their high accessibility, they have been well studied for a long time and their species are well known MAIN VEGETATION : Thuja plicata, Abies grandis, Salix lasiolepis, Alnus rubra, Populus fremontii ANIMALS: Aquatic animals, frogs, turtles, herons, fish
ROCKY SHORE
CHARACTERISTICS
Because flowers bloom at varying times of the year, the design of flower gardens can take into consideration maintaining a sequence of bloom and even of consistent color combinations, through varying seasons. Besides organizing the flowers in bedding-out schemes limited to annual and perennial flower beds, careful design also takes the labour time, and the color pattern of the flowers into account. VEGETATION: Jasmine, Crocus, Cyclamen, Bluebell, Violets, Periwinkles, Alpine Pasque Flower, Spring Gentians, Aquilegia, Aster Alpinus, Convolvulus, Cornflower, Cosmos Bipinnatus
FLOWER FIELD
CHARACTERISTICS
forestry and ecology comprises plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. VEGETATION: Plants in the understory comprise an assortment of seedlings and saplings of canopy trees together with specialist understory shrubs and herbs.
UNDERBUSH
CHARACTERISTICS
f the wearing away of land and the removal of beach or dune sediments by wave action, tidal currents, drainage or high winds. Waves, generated by storms, wind, or fast moving motor craft, cause coastal erosion, which may take the form of long-term losses of sediment and rocks, or merely the temporary redistribution of coastal sediments; erosion in one location may result in accretion nearby. VEGETATION: planting or maintaining native vegetation, such as mangrove forests and coral reefs.

in the so called “cerchia interna” the naviglio has usually a narrow section, due to the greater density of the city fabric.

STRATEGY 4
Rochy shore
This strategy is used at locks and the hight difference points along the system of Naviglio. The locks were used in ancient times for the boats, and are important in the history point of view. They make a high slope which block the continuity. This helps for providing a continuity alon the chanal, in the way that rocks are used and make a downward and upards slope and step.

stop from city flow and get in contact w i t h nature.
low vegetation fields are implemented in the darsena basin, to create a contrast with the city contest which allows an overview on the area.
the darsena basin is treated as a natural pond which serves as habitat of a large variety of species, from large to small birds and fishes of any size. This creates the possibility to have a complete alimentation circle

It relates to a vaste number of spontaneous arboreal species which naturally grows in not-human territories. In some situations the third landscape can expand and occupate bigger areas as parks.
abandoned buildings are used as condensators of biodiversity. Here human cannot access and a grater possibility for nature to grow in a more wild contest like continental forest is given.
