jardins en fête – bibliothèque Pechère

40 tuinen te bezoeken op zondag 25 september 2011
Na het grote succes van de edities in 2008,2009 en 2010 en dankzij de steun van het Brussels Hoofdstedelijk Gewest (Leefmilieu Brussel), beleeft het initiatief Tuinen in Feesttooi dit jaar haar vierde uitgave. Het grote publiek zal nog eens de gelegenheid krijgen om 40 privé- en semi-private tuinen te bezoeken, de ene nog origineler dan de andere, vol verrassingen!
Er zullen enkele tuinen bezocht kunnen worden die van Natagora het label “Natuur in de tuin” gekregen hebben.
De eigenaars van deze tuinen, de ontwerpers of voor het evenement opgeleide gidsen zullen het publiek uitnodigen om de charmes van deze “geheime tuinen” te ontdekken.

TV Brussel, Vandaag – 25 september 2011

experimentele tuin op een plat dak:
De hedendaagse experimenten van het internationale project TIK (Time Inventors’ Kabinet), in Brussel, gesteund door OKNO, zijn geestelijke verwant met de antieke tuinen, tuinen uit de renaissance- en barokperiode waar wetenschappen, kunsten en filosofie zich vermengen tot één enkele kunst. Men heeft het mis om een tuin alleen maar te zien als een charmant plekje met bloemetjes en vogeltjes …. Volgens Michel Le Bris, “moeten de twisten van tuinmannen worden gezien als metafysische twisten” (Le Paradis perdu. Parijs, Grasset, 1981). Op het plat dak van een saaie garage in het centrum van de stad vindt u een moestuin met kolen, een honingbosje, oude olijfbomen, bijenkorven, jonge vijgenbomen,… die gedijen in een vulkanisch substraat met het stadhuis van Brussel als achtergrond, alles goed georkestreerd door enthousiaste kunstenaars.

desert numerique 2011

Annemie Maes participates in the workshops, presentations and experiments of the festival Desert Numerique. She will present okno’s OpenGreens project. Desert Numerique is an artistic event gathering media artists, curators, producers, scientists, activists and publics around practices linking art, science and technologies; an invitation to bring digital arts in a unusual place, the village of Saint-Nazaire-le-Deesert (Drome, in France). It aims to transform the village into an electronical oasis, an effervescent laboratory.Desert Numerique combines a summer’s professional network meeting in the countryside and an exhibition made as an extension of the host village itself.

wasteland soundwalk

A soundwalk in Thurn & Taxis + workshop: create your own OpenGreen and connect to the database.

In the morning Jonathan Prior guides us through the sounds of the city during a silent soundwalk on the wasteland of Thurn & Taxis. How does Brussels sound? Can sound create a space? These questions are asked and explained, while we listen to the ecological aspects of public spaces. During this guided tour Jonathan Prior lets us experience the public space in another way. Take your waterproof shoes and your camera to register the sounds as images.
In the afternoon Danielle Roberts and Annemie Maes introduce you to the OpenGreens database. With the image material of the silent soundwalk we ‘recreate’ the wasteland of Thurn & Taxis in the OpenGreens database in a collective way.

We gather at OKNO – Koolmijnenkaai 30/34 – 1080 Brussels at 9am.

international Seed Swap and exhibition on seeds

Through this seed swap we want to draw public attention to a practice that has become increasingly widespread throughout Europe over the past few years and that could be made illegal by the planned EU laws: http://www.seed-sovereignty.org/EN/

Tens of thousands of people throughout Europe are actively demanding that the right to produce seeds remains in the hands of small farmers and gardeners. A diversity of crops has nourished mankind for thousands of years. Seeds that we have inherited from past generations are the basis of life and are essential for food sovereignty.
The big seed trusts are determined to obtain worldwide control. This has been made clear by genetic engineering, patents on plants and animals, the introduction of seed reproduction fees… Add to that terminator technology that destroys the fertility of seeds and the prohibition of peasant varieties. We must prevent the very basis of our food supply from becoming a source of profit for multinational companies.


the bee monitoring workshop 3+4/2

A workshop in which we try to understand the distributed intelligence of social insects (here a bee colony) : their behaviour, ecology and sociobiology. By monitoring the bees and beehives with all kinds of sensors, we study the colony as a community. We will document this research with all kind of media (photo, film, audio, text, code) and we will use the extracted data to make artworks based upon the bees behaviour over time. We try to connect nature and technology in a new relationship of interconnections.

To schedule our research and for purposes of documentation, we devide the work into 4 parts, which all will have their pages on the wiki where participants can add information:
1. The Theory + Reading List
2. The new BeeHives
3. The Data Harvesting (Technology)
4. The Artworks and Projects
You can find all info here:

wednesday 19.01.11 – compost – recycle day, spring cleaning
thursday 20.01.11 – the connected OpenGreens database
friday 21.01.11 – gift economy, the Kanal euro – complementary currency
saturday 22.01.11 – bee monitoring, enhanced beehives
sunday 23.01.11 – collaps

You can download the connected OpenGreens catalog (v.1.0):
The catalog will function as a basis for discussions at the OpenGreens corner.

bee-world: micro images

vijg03 varroa-color bij08-contrast vijg02
Enter the fascinating world of micro photography.
Check the minuscule fleshy parts on the ovary of a fig. Inspect a varroa-destructor mite, recovered between the thorax-fur of a honeybee. Calculate the cubitalindex on the wings of a bee, to determine her exact race and lineage. Be surprised to discover the fur cover of this little wild animal.

just a perfect day – 10.10.2010

Just a perfect day. Indian summer. The bees bring in pollen in abundancy. I just discovered the immense ivy covering the whole wall of la Bellone. Winterfood for my bees.
Today I started to note down the inside hive t° every hour, and compared it to the outside t° and the outside humidity.
In the sun, reading Indeterminacy. Cage was a well-known mycologist. Crazy about fungi. Short stories and mesostics about mushrooms. And later in the afternoon I met Thoreau. Walden & the civil disobedience. Wild is exiting, he says. And tame is dull.
Writing the wilderness. Can a poem give expression to nature?
Later, before sunset, cleaned out the rotten tomatoes but took their seeds for next year… and sown some winter lettuce in the cold greenhouse. The olives are slowly ripening and the figues are big and sweet.

The day and night of 2010/10/10 I did some measurements inside and outside hive#01. On the document you can see that the in- and outside t° are running up- and down on a proportional basis.
The t° sensor was placed at the outer inside of the hive, not in the broodnest itself. On saturday, october 16th, I expanded the observation by adding a digital thermometer to the hive#03, which is situated next to hive#01. I put the sensor in both hives in the broodnest itself. The average outside t° is much colder yet, at night the t° often falls down towards 4°.
I noticed the immediate rise of inside-hive t°, now that the sensor is in the center of the broodnest.
In daytime (no immediate sun) the hive t° was rising till 36°, at night the t° fell down to 23°. There is a difference of ± 3° in the average inside hive t° of hive#01 (less) and hive@02 (more). I don’t know (but should find out) if this t° difference is due to the (still) high varroa contamination of hive#01, even after 2 treatments with Thymovar.

The drawing on the rooftop is part of an art project by GOeART.

Following the Nazca lines, let’s turn the roofs of buildings and unused, abandoned spaces into works of art that can be seen from space! This is not just about being creative and artistic, but also making gestures on invisible, unknown and unused areas of our heritage. Being able to access aerial views of these areas is an unprecedented opportunity to practice a monumental art which says something about us, where we live or don’t live, how we relate to a globalised world, our intimacies, these holes, these windows which hide and reveal us … How? Let’s use the roofs of our city as something to draw on. You can’t see these drawings from terra firma, only from the sky. New works can be seen each time the satellites that take aerial views of our cities and areas pass overhead. Find our hidden guides, get up on the roofs and help create the first work of art visible from space.
