Dépollution des sols : la Chine cultive les plantes" accumulatrices" Les premières mentions de fougères utilisées comme accumulateurs d’arsenic remontent à 2001, année de la publication d’un article dans Nature. Le 3 juin 2009, le China Daily a publié un long entretien avec Chen Tongbin, spécialiste des sols à la CAS (Académie Chinoise des Sciences). Ce chercheur explique qu’après de longues années de travaux, il a mis au point une remédiation des sols pollués à l’arsenic dès 1999. Chen continue ses recherches sur le sujet mais ses découvertes sont aussi utilisées opérationnellement, par exemple dans le Hunan, à proximité de sites miniers. Ils ont entraîné, dans un rayon de 30 à 40 km, de fortes pollutions. La fertilité des sols cultivés est réduite à néant. Phytoremédiation : une technique "améliorée" Les sols peuvent être dépollués en 5 ans par la culture de Pteris vittata L ( Ptéris rubané), une fougère de la famille des Pteridacae.

The Urb – Urban Beehive for Homes by Chris Weir. Urban Beehive The reddot award winning Urban Beehive from Philips Design shows us that ant farms are obsolete and we should be gunning our attention on bees. The Urb is in line with the concept and makes beekeeping a ‘less daunting and more attractive process for novices.’ The biggest advantage is that you don’t need to adorn the protective garb when you handle the bin. You can observe the colony and use the technology implements to extract the honey easily.
Designer: Chris Weir. [INFOHIGHTECH] Istanbul: City of Seeds. It was generous of the The Building Information Centre (YEM) and 34Solo to host an xskool event in their city last week. Our starting premise, after all, was that Turkey’s 30 year long construction boom is losing momentum. True, the sound of jackhammers was pervasive in Istanbul during our visit – but the cold winds of the global crisis are making themselves felt. An estimated 600,000 dwellings stand unsold in the city and, in January, a first attempt to raise private funding for a third bridge across the Bosphorous failed.
Not a single company showed interest. Back in 1995, Mayor Erdogan of Istanbul declared that a third bridge would be “murder” for forests and reservoirs around the city. What drives this ecocidal policy? Trouble is, just because a property bubble is Too Big To Fail does not mean it will not fail. A next economy: already here This is where xskool comes in – as a kind of social seed exchange of the next economy. Centre and hinterland But a reality check is in order.

Maison. Projets Greenroofs.com - Changi General Hospital. The Changi General Hospital website states, "The hospital has made caring for the environment a priority, because the long-term benefits and savings help both people and the surroundings we live in. Patients are often worried and frightened when they come to a hospital. By beautifying the hospital with lots of plants and trees, we wish to create a more serene and restful environment for patients. Similarly, planting hydroponics on the rooftops provides food for the hospital, but also absorbs the heat from the roof, cooling the wards facing it. At the hospital, we also faced huge utility bills. The hospital started to look into ways of reducing energy and water consumption to eliminate wastage. Environmentally friendly practices all around the hospital were employed, such as recycling and management systems for energy and water. Générer des rendements plus élevés | VertiCrop.

Planters and urban gardening tools at Kennedy Greenway in central Boston, the site of the Occupy Boston encampment. Last spring, after attending a panel about urbanism in Mumbai, I wrote a blog post about what I called the "entropic city" — one that is constantly changing and re-imagining itself. “Entropy,” I argued, “is a cultural and an economic necessity. Restricting and channeling change imposes a dominant idea of what change should be, and what existing conditions are undesirable. But it also stifles innovation and creates monocultural economic environments that are vulnerable to dramatic changes. This post got a lot of attention, which got my attention. But there is a lot more potential to tactical urbanism than placemaking.

Multifonctionnalité de l’agriculture urbaine à Montréal : étude des discours au sein du programme des jardins communautaires. 1Depuis 2008, plus de la moitié de la population mondiale habite en ville (UNFPA, 2007).
Face aux problèmes soulevés par le phénomène de l’urbanisation, l’ONU propose, à travers de nombreux rapports, la notion de ville viable. Cette notion s’inscrit dans un champ plus large, celui de développement durable. Ce dernier tend à corréler les dimensions économique, sociale et environnementale et se dote d’un outil de mise en application avec l’Agenda 21 local. Le recensement des écrits portant sur la notion de ville viable depuis Rio 92 montre qu’il existe une bonne connaissance des problèmes et des solutions soulevés par le contexte urbain mais, qu’au-delà de la rhétorique, les actions concrètes pour une mise en œuvre d’une ville viable ne sont pas à l’image des discours et peuvent être même qualifiées de décevantes (Brunet, 2006).

Atelier d'architecture autogérée. Atelier d'architecture autogérée (aaa - Studio for Self-managed Architecture) is a practice based in Paris co-founded by architects, Constantin Petcou and Doina Petrescu in 2001. aaa acts as a platform for collaborative research and action on the city and much of their work is carried out with other specialists, artists, researchers and institutional partners such as universities, arts organisations and NGOs, as well as the eventual users of their spaces. Whilst the founding members of aaa remain, the practice operates as a collaborative network that forms around each project. aaa's projects are experiments in the temporary reuse of leftover urban space through the setting up of an enabling infrastructure that is slowly taken over by local residents and transformed into self-managed spaces.

Un tempo oggettuale dunque succede a un tempo dei grandi simboli urbani. Esperienze teoriche hanno origine dentro a una idea di industrial design e non certo a quella di composizione architettonica tradizionale.
Una sorta di diffusione planare dei processi costruttivi corrisponde alla logica di una civiltà senza cattedrali, agricola più che industriale. Le nuove frontiere del design si muovono oggi nella direzione che va a collocarsi nell'estensione del sistema oggettuale alla scala del territorio metropolitano. Una direzione teorica e progettuale che vede oggi la città come un sistema di micro-strutture di servizi e di relazioni, che solo in minima parte possono essere attribuite all'architettura tradizionale, compositiva e metaforica, e in grande parte sono di competenza di attitudini progettuali diffuse, deboli, oggetto di un urban management capace di gestire e sviluppare la concorranza urbana, ma non di produrre scelte irreversibili.

Urban Agri_Polis er en fusion mellem to verdner; en verden hvor urbanitet møder rural landbrugsproduktion, hvor det grå beton møder den grønne natur og hvor byboerens pulserende liv møder bonemandens hverdag. Urban Agri_Polis forsøger at fremme et afbalanceret forhold mellem den byggede by og landbruget, som formodes at ville understøtte hinanden i harmoni og med respekt for hinandens eksistens. Tiltel Urban Agri_Polis beskriver kombinationen af urbanitet, defineret som byens tætte struktur, landbrug, defineret som kommerciel landbrugs produktion og Polis som referer til storbyens pulserende liv.
Urban Farming. The practice of cultivating food and raising animals in an urban environment is referred to variously as urban farming or urban agriculture. Whilst small-scale and localised food production has a long history, including individual allotments which have been popular in Europe since the late C18, it is the integration of such farming practices within the economic and ecological system of towns and cities that is a newer development.
This means that urban resources such as compost from food waste and waste water from urban drainage is made use of, whilst urban problems such as the pressure on land and development also have to be negotiated. The recent of example of Cuba has proven the effectiveness of urban agriculture, where it played a critical role in ensuring food security after the collapse of the Soviet Union in 1989.

Some days ago we published the first of a serie of projects from the the President’s Medals for Students Projects organized by theRoyal Institute of British Architects (RIBA).
The winning entries will be published on December 2, so in the meanwhile, we continue publishing some of the students projects that are participating. This time the project is called SERVER and it was presented by Alastair Parvin from The University of Sheffield Sheffield UK. We have talked before about food problems in cities and the different solutions that can be developed, such as vertical farming or urban farming.
This time Parvin’s proposal has more similities to MVRDV’s Pig City than with skyfarming and the project speculates upon whether we can redefine what is actually meant by the term ‘local’.

Le mode alimentaire américain basé sur une très forte consommation de viande de boeuf est une catastrophe écologique pour la planète - voir là et là, et risque de dévenir un enjeu d'aménagement urbain essentiel dans les décennies à venir - voir là. D'autres vont plus loin en imaginant carrément des immeubles associant en plein coeur de villes des élevages verticaux couplés à des abattoirs.
C'est notamment le cas d'Amir Yousefi avec son projet "Carnivore Factory". On peut trouver cela terrifiant. On peut aussi imaginer que le visage des fermes évolue dans les années qui viennent pour donner naissance à une nouvelle "farmitecture"- voir les explications sur l'image ci-dessous là.

I will share here a low cost solution for the recycling of organic waste, appropriate for apartments and urban housing that do not have a piece of land or an outdoor area. This construction is inspired by the Cadico earthworms nice project. The photos are from the composter I made here at home : ) It’s called a Vermi composter because we use worms in the process, uhuuuuu big thanks to the worms, they deserve!
To make this kind of composter, it is important to use stackable supports to separate the different stages of composting. In this case, I used 3 buckets of margarine 15L reused. You can ask for them for free at local businesses such as coffee shops, bakeries, juice houses, etc.. The first step is to cut the center of the lids that stands between the buckets. Then we will make holes into the bottom of the 2 buckets that will stay on top and receive the organic waste. We also make small holes in the lid that will stay on top and was not cut: We use the California red worms. . . . . .
