In 2007 the Italian architect Stefano Boeri designed 'Bosco verticale', the vertical urban forest. He became welknown worldwide by this project. 'Vertical Forest' is a tower with 1500 trees. This vertical forest project is a plan for biological architecture with an area with a high density of residents and trees. This plan allows the vegetation within it to absorb dangerous dust particles in the air, and aims to create a suitable microclimate to allow the sun to filter through. Meanwhile it is under construction in Milano. [more about Bosco verticale click here] One of the most exiting buildings of this time!

Meanwhile Stefan Boeri is preparing a project for the Expo 2015: a global kitchen garden.
The project for EXPO 2015 is based around a model for new forms of local agriculture which surround Milan. A vast global kitchen garden will be created, as well as a large space for agro-food production which will produce food for a cosmopolitan metropolis.

He has been going on with thinking about mega cities and came with six ideas for a bio-diverse metropolis:
Six transitional states between the city, nature and agriculture and
Six energy sources for a new model of urban economics.
In februari 2011 an exhibition at Rome was dedicated to his ideas. Worth to have a look at it.

These six ideas has been worked out on the example of Milano, his home base.
Stefano Boeri describes it like this:
"Milan, like every city in the world, today, is at a crossroads.
It can continue growing by eating up agricultural land, woods, natural space, and thus reducing biodiversity and the space available to other species.
Or it can choose to become a bio-diverse metropolis, starting with a new agreement between the city, the natural world and agriculture.
BioMilan provides a vision of a city which stops expanding into rural areas and choose to grow by regeneration and by increasing the presence of natural and biological spaces.
BioMilan has at is heart the idea of a new kind of agriculture which surrounds the city, provides work and produces for local agro-food markets.
BioMilan allows nature to find spaces where it can express forms of biodiversity, both inside and outside of the city’s borders.
BioMilan is a political project which aims to increase the number of businesses which, working together in areas linked to agriculture, forestation and renewable energy, can regenerate the urban economy and provide forms of integration and work for thousands of citizens.
BioMilan’s six projects which can be seen in this exhibition outline the economic and territorial energies which are needed in order to arrive at a new balance between the urban sphere, rural areas (cultivated forms of nature) and the natural world."

Wood House: social housing and the tree cycle
The Wood House project aims to build low density and low cost social housing by using prefabricated forms of architecture and wooden panels recycled after conservation work on the trees which run along the Ticino river.

Courtyard Farms. A constellation of epicentres within systems of neighbourhood agriculture
The project for the restoration of 60 publicly owned and abandoned courtyard farms around Milan has its origins in the plan to create a new relationship between the city and new forms of agriculture. This kind of agriculture is more varied than in the past (fruit and vegetables, cereal crops, productive woods, bio-mass) and produces for the city as well as allowing for different kinds of research, training and work.

Metrobosco: a forest around Milan
The Metrobosco project will develop a ring of trees around Milan which can encourage animals to settle there from those non-domestic species which are common in the hinterland areas close to the city.

Biological and plant decontamination of polluted urban areas
The cleaning up of ex-industrial areas and obsolete structures in the city through biological and plant cultivation creates new possibilities for public open space. Through the cultivation of polluted land, they can be cleaned-up and biomass is also created, and in this way the city can regain lost spaces which were seemingly lost forever.
