A LABORATORY ON CONNECTED ROOFS

For the artist, the empty rooftop is a blank canvas. It is embedded in the city and offers a perception without geographical limitations. It’s up to the artist to combine the artistic eye with scientific observation. The public has to travel to the location and has to put effort and time (= engagement) to discover the artwork.
New forms of sculpting the public space can be found in rooftop hacking and squatting, transforming rooftops into urban fields, short chain agriculture. These are interdisciplinary activities situated between art and the broader Continue reading

ECOSYSTEM OF THE ROOFTOP GARDEN

Ecosystems include living organisms, the dead organic matter produced by them, the abiotic environment within which the organisms live and exchange elements (soils, water, atmosphere), and the interactions between these components. Ecosystems embody the concept that living organisms continually interact with each other and with the environment to produce complex systems with emergent properties, such that “the whole is greater than the sum of its parts” and “everything is connected”.

STEP BY STEP BUILDING THE FARM, phase#2

During a few sunny spring weekends we work with a bunch of friends to install the farm on the parking rooftop Dansaert2, and to bring the farm to its full capacity: 44 containers of 125cm x 125cm. The containers are palox europallets, recycled from small fruit&vegetable companies. They are made of hard oad wood. We customize the containers on different heights, suitable for growing herbs, greens, roots and small trees.
The construction workers next doors help us to bring up soil and other materials with their crane. When the basic outline is nearly ready and the hardest work is done, Continue reading

THE DIGITAL GARDENER & THE VISIBLE WEATHER

We connect local OpenGreens in an international network of experimental gardens where artists work with natural processes.
These gardening situations serve especially to look into microsociological and ecological systems related to time as starting points for the development of new artistic practices. The OpenGreens allow us to study the implementation of contemporary art in an ecological context and to observe and draw content from eco-data and natural patterns and processes.
Using media technology and electronics as research tools in these shared laboratories, data from various ecosystems are collected over a period of time. Continue reading

BEE ANATOMY

Honey bees have 5 eyes. Two compound eyes, these are made up of many hexagonal facets, meaning that they can simultaneously see all around them (above, below, side to side, infront). Like humans, bees are trichromatic, but whereas humans base their vision on red, blue and green, bees base their colour vision on blue, green and UV. This means that some colour combinations visible to bees, are not visible to humans. However, bees cannot see red, however, they do visit red flowers because they can see the UV patterns within the petals. And they also have three ocelli: these are simple eyes positioned on top of the head. These eyes are sensitive to light, and aid the bee in its orientation. The Proboscis is a long tongue which the bees use to suck nectar from flowers into the mouth. Antennae are vital for touch and smell. They are used for communication within a honey bee colony , for locating food, for sensing predators, and even aid flight.
The thorax is the anchor for the legs – the hind legs also featuring pollen baskets. The forelegs are used for cleaning the antennae. The thorax contains the flight muscles and salivary gland. There are 2 pairs of wings attached to the abdomen. The abdomen contains the honey stomach which enables the bee to carry about 75 mg of nectar from a flower back to the nest or hive. The sting is a modified egg laying organ. Only females are able to sting, and do so only when they feel threat of attack.

HISTORY & URBANISM: SENSE OF THE CITY

I discovered that the location of the 2 rooftopgradens has a rich history, tracing back to 1235, when the convent of the ‘White Sisters’ was established. In 1456 Philip the Good integrated the White Sisters in the cloister of Jericho. The address was on the Oude Graanmarkt, right around my corner, and their land had a surface of 4 hectares. They had vegetable gardens and orchards and even their own brewery. It is great to know that we can add another layer on top of this wonderful history. Continue reading

KNOW YOUR SOIL: REQUIREMENTS FOR BIO-DYNAMIC VEGETABLES

Each different crop will be grown in a wooden palox box of 125×125. With 1m3 (1 cubic meter) of soil we can fill up 4 to 5 boxes with a layer between 12 and 30 cm of bio-soil, mixed with compost or ecoveen (along the needs of the plants). At dewinter groencompost, we ordered in januari 2012: 6 x 1m3 teelaarde + 2 x 1m3 edelcompost + 1 x fijne groencompost + 1 x ecoveen.
In februari 2012 we put a complementary order of: 12 x 1m3 teelaarde (from which 5m3 will be prepared in 10 bigbags Continue reading

STEP BY STEP BUILDING THE FARM, phase#1

Everything should be made as simple as possible, but no simpler. Einstein

December 2011 I made the first designs for the creation of an Urban ArtFarm.
The Urban ArtFarm (2012) is an extension of the existing edible rooftop garden (2009). The 2 intensive rooftopgardens are situated on top of adjacent parking lots and are physically connected. The edible rooftop garden is specialised in mediterrean and medicinal plants, herbs and flowers – all with an important nectar/pollen value. Continue reading

SITE SUSTAINABILITY & PERMACULTURE PRINCIPLES

Sustainable gardening: design, construction, operations and maintenance practices that meet the needs of the present without compromising the ability of future generations to meet their own needs. This can be reached by attempting to protect, restore and enhance the ability of landscapes to provide ecosystem services that benefit humans and other organisms.
Checklist: local climate regulation; air and water cleansing; water supply and regulation Continue reading

3 ECOLOGIES AND THE HUNGRY CITY

Can the creation of a rooftop garden be considered as an artproject?
I will formulate an aswer on this question later.
More and more people are living in the cities. We have to search for new modes of sustainable living, new ways of food production. Re-examine the link between the city as consumer and the countryside as provider. In this context, we are researching how to make a network of intensively cultivated city rooftopgardens where we can grow food for the neighbourhood. Continue reading
