00. politics of change



UrbanFarm-[Original] or UF-[O]
UrbanFarm-[Original] or UF-[O] is an experimental station for Urban Agriculture on a rooftop in the center of Brussels

  Today we no longer have the right to pretend that we command a unique position 
  from which we can view the truth about the world. 
  We must learn not to judge different areas of knowledge, culture, or art, 
  but to combine them and to establish new ways of coexistence with those 
  who enable us to meet the unique demands of our time.
  Ilya Prigogine & Isabelle Stengers, Man’s New Dialogue With Nature,1979

01. the Urban ArtFarm project

The Urban ArtFarm is an experimental station for Urban Agriculture. It researches and analyses the pro and contra's of growing food in the city on rooftops of bigger buildings, with the help of green DIY technology. How does a rooftop ecosystem deal with energy, water, soil and green technology? What does the project represent financially? How do plants and animals (city honeybees) interact with this artificial ecosystem?
UAF (Urban ArtFarm) is an open air laboratory that interacts with the city. The base station is built on connected rooftops in the historical center of Brussels, connections or nodes to this location can be setup on any other rooftop that is suitable for the purpose. The groundlevel location of UAF is the place on the Brussels'map where a network of medieval market places and monasteries intermingle. The UF-[O] farm, set on the 6th floorlevel of this place, on the roof of a parking lot, is a place where artists and urban gardeners can develop new strategies for sustainable living in the city. An artistic approach, green DIY technology and a permaculture philosophy should present new opportunities to the citizens to connect to food, food security and sustainability.

growing food for the hungry city : is it still art?

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 our own food for the neighbourhood.

Besides the food-function, the UrbanFarm-[O] is set up as our open-air laboratorium. In this project, we want to blend the natural and the digital in one and the same nature. We study and document how to set up a middle sized rooftopgarden (± 700 m2), all with recycled materials.
Artists occupy the public space and develop activities with a specific ecological focus: hack the top level of city and give it another destination. Connect different rooftops in a network of OpenGreens with city honeybees as connectors and bio-indicators.
The UF-[O] project blends nature and technology. By digital means it explores how the growth, blossoming and decay of plants occur while they are submitted to different abiotic elements as wind, rain, sun, etc.
Can we learn something from the data resulting from the monitorings? Is our environment programmable? Does the fusion of natural and artificial matter produce new organisms, new environments, new natures? Elements of the garden, plants as well as technology, become nodes in wireless networks. This happens both on rooftop level as on city level.
The connections between people, plants, sensornetworks and utilities of the rooftopgardens are mapped for further study. We research the collected data in the context of the 3 ecologies (Guattari, 1969) : ecological, social and political.

artistic research: 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 social and political world. Their aim is to provoke a change. It are forms of site-specific art. The natural environment as in a process of a constant change, the city layers overwritten by various urban systems: socio-political and historical but also industrial and economical systems. The work involves natural processes, but as well elements of technology.
Important is the recultivation of the land/location, the historical act of rewriting, of adding new layers, with the help of earth/art methods, DIY instruments and technology. This new world is perceived from the perspective of the 3 ecologies as stated by Guattari: social, mental and environmental. The eco-logic can be found in everydays’ life. The existence for the art world is confirmed as covered by film, audio recordings, photographs, maps, diagrams, drawings and storytelling.

Open Greens : marginal zones where culture and nature overlap and enter into a symbiotic relationship.
The project researches different bottom up approaches for designing human environments that have the stability and diversity of natural ecosystems. Integration of renewable energy systems, energy efficiency, food/gardening systems, natural building, rainwater harvesting and urban planning along with the economic, political and social policies that make sustainable living possible and practical.
The Kabinet of the OpenGreens (padma, COG and other databases) is a repository for all the documentation materials on city gardens, abandoned agricultural and industrial spaces, miniature parcs on balconies and window sills, participating in the OpenGreen project.

urban ArtFarm : stadslandbouw als artistiek project

De UrbanFarm/Original (UF/0) is een onderzoeksstation voor stadslandbouw. Het is een openlucht laboratorium van 750m2 dat gebouwd is bovenop platte daken van grote gebouwen. Hier onderzoeken we de interactie met de stad op verschillende niveaux: sociaal, politiek, economisch en ecologisch, en dit alles vanuit een artistieke invalshoek.
Hoe gaat een artificieel opgezet ecosysteem om met natuurlijke resources als energie, water, grond en hoe wordt groene technologie hierbij betrokken? Het project test de pro en contra's, de voordelen, problemen en knelpunten om voedsel te verbouwen in de stad, en maakt de resultaten publiek via artistieke interventies.

De locatie van UF/0 kent een rijk verleden: tijdens de middeleeuwen was de plaats een belangrijk knooppunt in een netwerk van kloosters, kruidentuinen, boomgaarden en stadsmarkten. Voor het UF/O-project hebben we echter de begane grond verlaten en hebben we ons openluchtlaboratorium ingericht op een knooppunt van aaneengrenzende daken. Hier ontwikkelen kunstenaars, DIY-wetenschappers en stadstuiniers nieuwe strategieën voor duurzaam leven in de steden van vandaag en morgen. Een creatieve benadering, groene technologie en een filosofie die haar oorsprong vindt in de permacultuur liggen aan de basis van dit project. Het netwerk van daken wordt omgevormd tot OpenGreens. Artistieke interventies maken onverwachte verbindingen tussen de stad en haar bewoners en creeëren nieuwe invalshoeken met betrekking tot voedselzekerheid en duurzaamheid.

Meer en meer mensen leven in de steden. Daarom moeten we zoeken naar nieuwe vormen van duurzaam leven, maar ook naar nieuwe manieren van voedselproductie. Het verband tussen de stad als consument en het platteland als leverancier moet herbekeken worden, uitgaande van een creatieve samenwerking. In dit kader onderzoeken we hoe we een stadsnetwerk kunnen opzetten van intensief gecultiveerde rooftopgardens, waar we ons eigen voedsel verbouwen voor de buurt.
Maar de UF/0 is meer dan enkel voedsel. De UF/0 is opgezet in een artificiële omgeving, met gerecycleerde materialen, biologisch zaaigoed en respect voor de natuurlijke bronnen als water en energie. Tiijdens de duur van dit project willen we deze processen monitoren, archiveren en beschrijven. De 4 seizoenen worden gelinkt aan data en timelines, er wordt gewerkt met DIY meetapparatuur, de dagen worden beschreven in klank en beeld. Het natuurlijke en het digitale gaan deel uitmaken van 1 geheel.
Kunstenaars bezetten en connecteren de daken en ontwikkelen activiteiten met een specifieke ecologische focus. Ze hacken het hoogste niveau van de stad en geven het een andere bestemming. De verschillende daken vergroeien tot een netwerk van OpenGreens.
Deze OpenGreens schakelen aaneen tot bio-corridors. Ze worden druk bezocht door stadsbijen die tevens ageren als bio-indicatoren. Met digitale en analoge middelen onderzoekt het UF/0 laboratorium de cycli van groei, bloei en afsterven van planten en honingbijen in dit specifieke ecosysteem, terwijl deze zijn blootgesteld aan de tijd en aan elementen als wind, regen en zon. Biotische en abiotische elementen worden knooppunten in onze groene observatie- netwerken.

Wat kunnen we leren uit de resultaten van deze observaties? Is onze omgeving programmeerbaar? Kan de fusie van natuur en techniek leiden tot nieuwe omgevingen, nieuwe materialen, nieuwe oplossingen? Kan dit onderzoek bijdragen tot het ontwikkelen van duurzame steden?

een kunstproject op een dak in de stad

De daktuin in het midden van het stadscentrum is het resultaat van een mix van disciplines: een kunstinstallatie, landschapsarchitectuur, poëtica, stadslandbouw, tegencultuur, transitie en duurzaamheid. Deze zijn de basisconcepten voor een nieuwe benadering van een ongewone plaats en van de mogelijkheden die deze lege ruimte in zich draagt.
De experimentele tuin op het dak van de parkeergarage etaleert een complexe esthetische en formele gevoeligheid die in harmonie is met zijn omgeving.
Het project wordt gedocumenteerd en beschreven in termen van zijn compositorische modaliteiten, maar ook de technische realisatie, de biotische en abiotische factoren en het proces van transitie komen aan bod.
Het boek beschrijft de creatie van een nieuwe en totaal andere ruimte voor deze ongebruikte plaats; de transformatie van leeg dak naar openlucht laboratorium symboliseert een nieuwe aanpak die bijdraagt tot het onderzoek naar duurzame steden en het creëren van biocorridors in het stedelijk landschap.

Dit stukje kunstmatig gecreëerde natuur, opgebouwd door een collectief van kunstenaars, denkers en doeners, transformeert de ongebruikte dakruimte tot een locatie die een intensieve dialoog uitlokt met de gebruikers.
De subtiele aanpak van de kunstenaars formuleert een ecologisch bewustzijn dat focust op het geheel van nieuwe mogelijkheden. De experimentele tuin is een installatie die laat zien hoe kunst een broedplaats kan zijn voor andere invullingen van de stedelijke ruimte. Een ecologische visie waarin kunst en (landschaps)architectuur hun mogelijkheden combineren.
Deze installatie maakt het onzichtbare zichtbaar: dit is de missie van kunst en tegelijkertijd de rol van de architectuur. De vraag wat natuurlijk en wat kunstmatig is verliest haar absolute betekenis.
In de loop van het proces maken de kunstenaars de verborgen schoonheid en kwaliteiten van deze plek zichtbaar. De essentie ligt niet meer in de vormen en gebruikte materialen, maar in de kracht en de intensiteit die van deze plek uitgaat.
De natuur leert ons hoe we op een kunstmatige plaats dezelfde ruimtelijke sensaties kunnen reproduceren als degene die uitgaan van een natuurlijk landschap.

een plaats om te ontdekken
Het UF/O - dak is de ruimtelijke vertaling van een concept, een levende sculptuur.
Het realisatieproces onthult in poëtische beelden de relatie van de locatie in het verleden tot zijn plaats in het hedendaagse stadsbeeld. De open taal is in lijn met de trage, natuurlijke evolutie van de daktuin.
Het project formuleert een radicale kritiek op de urbanisatie van de jaren '70, de beton explosie tijdens het olietijdperk en de realisatie van tal van parkings in het stadscentrum die afbraak van woonhuizen en roofingwoestenijen tot gevolg had.
De UF/O en de 'Tuin van Eten' willen de tegencultuur een hart onder de riem steken, en staan volledig achter het toeëigenen van ongebruikte publieke ruimtes en de guerilla-gardening. We moeten toe naar een herdefiniëring van de publieke ruimte, met inbegrip van een herdefiniëren van instrumenten die nodig zijn om deze ruimte in te richten.
We moeten de openbare ruimte opnieuw analyseren, en ze op een nieuwe manier gaan waarnemen, opmeten en in perspectief zetten tot de stedelijke structuur.
Van verlaten en marginale zones die opnieuw worden ingenomen door de natuur kan een verleiding uitgaan die zijn kracht kan overzetten op de rest van de stad, het ontstaan van een osmotische relatie met de omgeving.
Het werk van de kunstenaars is gelimiteerd tot het conceptuele en artistieke gebruik van de ruimte. Daarom is het belangrijk dat toeëigening en verandering van bestemming gedocumenteerd worden, het proces moet beschreven worden. Hiervoor wordt een specifieke visuele taal ontwikkeld die aanleunt bij urbanisatie en (landschaps)architectuur.
Dit transdiciplinair onderzoek documenteert dus gedetailleerd het creatie- en groeiproces, waarbij ook reflectiemomenten een belangrijke plaats toegewezen krijgen.
De kritische analyse van dit experiment vloeit voort uit de noodzaak om de stedelijke structuur en publieke ruimte anders te benaderen. Met nieuwe onderzoeksinstrumenten, nieuwe talen, waarbinnen de participatie van de burgers een belangrijke plaats krijgt toebedeeld.
Een nieuw kijk op 'urban voids' die reeds lang over het hoofd werden gezien, en deze letterlijk 'bezetten met andere betekenissen'.

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”.
The habitat is that geographical unit that effectively supports the survival and reproduction of a given species or of indivuals of a given species; the composite of other organisms as well as abiotic factors therein describe the geographical unit. Other organisms include the plants, animals, fungi, bacteria, viruses and protozoans that also live in a given habitat. Abiotic factors include soil types, water availability, temperature, sunlight, air quality and geometric aspects of landforms that facilitate resting, foraging, nesting, mating, metabolic functions and other activities.biological corridor: connected open greens corridor for the bees, preservation of biodiversity: creating and maintaining biological corridors are important steps towards restoring natural habitats that have been fragmented by natural and human induced processes. By re-establishing and supporting biodiversity, many species are given an opportunity to continue existence in the wild. Conservation organizations continue to research and identify areas that are suitable for these connections, and educate the public about methods of creating habitat corridors.

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.

permaculture principles

The OpenGreens project covers different bottom up approaches for designing human environments that have the stability and diversity of natural ecosystems. Integration of urban agriculture, honeybees and their role in urban ecosystems, renewable energy systems, food sovereignty systems, natural building, rainwater harvesting and urban planning along with the economic, political and social policies that make sustainable living possible and practical.

10 principles of permaculture design according to Bill Mollison* relative location: how elements of the design are in relation to other elements. What are the connections between them?

  • multiple function: each element of the design should perform at least 3 different functions. (trees⇒ windbreak, food, rooftop insulation, …)
  • multiple sources: not rely of just 1 source of something (water, energy, …)
  • zone: place the elements of the design according to their frequency of use. Also check the control and utilisation of the energies entering/passing through the site (cold winds, summer sun, …)
  • energy cycling: harvest as many nutrients and energy from the garden design
  • using biological resources: using the natural qualities of things, companianplanting, pest-controlling insects, …
  • stacking: observations of natural systems as three dimensional systems (7 layers)
  • diversity: a diversity of plants, a social and economical diversity (people, providers, …)
  • edges: productivity in natural environments increases at edges between different ecosystems. Has to be taken into account when designing the garden. (hedges, ponds, beds, …)
  • small scale: keeping a garden intensive and small

06. green technology : 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. The artistic output of this data collection process will be the creation of electronic interfaces that will then be used to reinterpret the data to explore time-related poetics such as synchronicity and irregularity through electronics, and of developing a common language about time.

The synonyms for an OpenGreen are many: the experimental Hortus, the OpenAir Laboratorium, the Vivarium, the Kabinet of Wonders. But all OpenGreens are zones where culture and nature overlap and where these two enter into a symbiotic relationship with research and experimentation.
In the OpenGreens, the Time Inventors document the beauty of nature in data. They classify and archive their notes and findings in OpenGreens databases. They compare and develop concepts, interpret complex biotic shapes and research repetitive natural patterns. They connect nature with media art.

There are architectural models that are made after biomimesis of e.g. hexagonal honeycomb cells; data are extracted from plant-connected sensors and are converted into algorithms that generate abstract visualizations. Analogue or digital approaches: the Time Inventors make use of a diversity of methods to study the art forms in nature.
But, how can the OpenGreens’ evolution be visualized or made audible in artworks? Can the gardens’ (a)biotic organisms' processes provide new artistic environments or new forms of representations of ‘the artificial/nature’? How can art and technology today present a different view on nature?
During the TIK-time of the project, artists delve into the matter and with the mutual aid of scientists and engineers they open an investigation that may lead into some unexpected artistic results.

The Brussels OpenGreens have a strong urban embedment. In two related urban rooftop gardens artists carry out long-term observations on the growth, blossoming and decay of plants exposed to natural elements such as wind, sun, rain and pollution in an urban context. The close monitoring of social insects, in this case several colonies of city honeybees, is an important part of the study.
These urban OpenGreens are artificial environments, hybrids of nature and culture. They are set up to research different bottom-up approaches for designing green human environments that have the diversity of natural ecosystems.
 The OpenGreens database keeps accurate track of the monitoring of these ecosystems. Technology is inserted in the gardens and allows the gardeners to take a closer look at biotic matter. The harvest is about collecting data of any kind, both on a micro garden level and on a macro city level, and using the data for organic and media applications.
All Time Inventors interested in monitoring their city gardens or urban edgelands and compare their observations are invited to become contributors to the OpenGreens database.
Everybody is free to use the open data format in the OpenGreens database (xml) for their personal artistic projects.

In this section we will gather information and develop methodologies on how to work with the gardens and describe them on defined moments of the season's timeline.

  • Plants as inspiration for a changing mindset. Plants are sustainable, they recycle their own waste, they produce their own energy (photosynthesis). They fertilise the soil (organic/anorganic matter) and clean the air (Co2/ photosynthesis)
  • neon sign works / plants / photosynthesis
  • storytelling on the graphs of the bee-monitorings
  • Study the farm as a living organism, the skin of the rooftop, equipped with sensors to measure all weather conditions. Working with intelligent materials that can adapt to changing conditions (try-out in controlled environment as greenhouse) and situations. Make sculptures with meteo-sensors and stylized models (drawings and/or computer generated models) that are realized after microscopic studies of of flowers and vegetables. These digital models can react in realtime to weather-sensor-data (ex. the seedpod of the Daucus carota).
  • Artforms in nature, biomimicry, biomimetics. Integrated organic and sustainable design, optimal use of materials (harmonious, balanced, efficient). Exploration of forms and structures (electronics, computer, wireless technologies). Dynamic buildings and building methods, adapted to changing environmental conditions. The rooftop as a skin, a living organism (programming, coding, 3D printing & modelels, simulations).
  • City honeybees: patterns described in algorithms of packing/blending/flocking/tiling/spiralling/weaving. Building libraries of natural behaviours distilled into algorithms. Transforming the natural into the artificial, into the digital.
  • make a taxonomy of urban agriculture and rooftop garden language. Set up an annotated knowledge base of artefacts and projects, useful for understanding and learning from their evolutionary lines, their timelines. Learn out of the intersections and cross-pollinations.
  • pollen pantone charts: find the neighborhood's algorithm - space/time
  • introduce the questionnaires of Politics of Change, introduces same questions in book UF-[O]
  • transparant beehive, bee-appartments simulation/ models
  • topography of a garden: series of macro photography (specific presentations)

The greenhouse rooftop garden is an extension of the yet existing edible rooftop garden. 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.
The greenhouse rooftop garden focuses mostly on fruits and vegetables. Both gardens are set up along the principles of permaculture. They both host several bee colonies, and are very friendly to other pollinating insects and birds.
In both gardens we work with recuperation of rainwater and we make our own compost. We will set up alternative energy systems with solarpanels to power the waterpumps. The beehives are monitored with custom-made, low cost technology.

In februari 2012 we put a complementary order of:
12 x 1m3 teelaarde (from which 5m3 will be prepared in 10 bigbags of 1/2 m3 for the trees; and 7m3 will serve for the vegetables)
3 x 1m3 fijne groencompost (for adding during the season to the crops growing)
1 x ecoveen (for keeping the water up in times of drought)average weight goes as follows:

  • teelaarde: 800 kg/m³
  • teelaarde+: 700 kg/m³
  • gewone groencompost: 525 kg/m³
  • fijne groencompost: 550 kg/m³
  • ecoveen: 230 kg/m³gewone groencompost is door zijn iets grovere struktuur het best geschikt voor diepere grondbewerkingen en bij het aanplanten van houtachtigen.

fijne groencompost is ideaal voor oppervlakig gebruik bij zaaien of planten en als toplaag voor gazon.
edel compost is een mengsel van fijne groencompost aangerijkt met organische voedingsstoffen en gebruikt men best daar waar opbrengst belangrijk is.
ecoveen is de ecologische variante voor turf met gemakkelijke waterabsorptie en een goede bewerkbaarheid.

WATER management systems

4 x 1000 liters in series 2 x 250 liter recuperated from the greenhouse roof 250 liter
water recuperation (from appartment rooftops and from the greenhouse rooftop)

We collect the rainwater from the surrounding rooftops to foresee in the water supply of the rooftopgarden. As the rooftopgarden has a limited amount of soil, and as the elements as wind and sun are very present and dry out the soil faster than they do in a 'natural' vegetable garden, the watermanagement in the containers becomes very important. It takes up to two hours to water the vegetable garden manually, with the hose. Therefore we decide to install an automatic wateringsystem, consisting of a microdrip system that is connected to the watertanks and that is controlled by humidity sensors.

For automating the wateringsystem in the rooftop garden, we planned a workshop with Jonas Z. to find out the possibilities of his OSMOGAS concepts in real physical situations.
OSMOGAS (open source modular gardening systems) researches easy deployable modular systems for gardens. It consists of three main groups of modules. The first group are evironmental measurement sensors (air pollution, humidity, temperature, UV, wind, pH, …), the second group focuses on the 'outputs' (digitally controlled switches for water pumps, lights, fog-generators, …) and the third group develops stand-alone systems or the connections to bigger systems (computers, servers). The project focuses on simplicity, DIY and user friendlyness while designing and producing the modules. All code is available online, as well as the schemes and drawings for DIY, and manuals are edited in an understandable language.

Measuring moisture can be done very cheaply and easily if done with care. Basically, it is based on the water conductivity in soil - the more water in soil (bigger moisture), the more conductive it gets. We measure the conductivity by simply trying to push current trough the soil and measuring how much get trough. This is done by pair of wires or nails at circa 2 cm distance.
To connect such sensors, we work as with other resistance based sensors - to one pin we provide 5V and from other pin we get the output. It is required to use a pull down resistor as well. This means, we connect a smaller resistor from the output of the sensor to the ground.

sunlight, temperature, water drainage and fertilizer control
Another garden automation system is called GardenBot. It uses open source hardware (Arduino) to monitor humidity, temperature and soil conditions. The data is then poured into charts. The GardenBot’s brain is the Arduino board. The rest of the system has a garden station, which is a junction box for all the sensors and a place to secure the wiring.
The key modules for the system are soil moisture sensor, soil temperature sensor, light level and water value. Each of these modules can be built separately and integrated into GardenBot. Once GardenBot is live, it can send data to a computer so that the information is plotted on a chart and updated every 15 minutes.

⇒ 5 x 4000liter wateropslag (van het dak) wordt opgeslagen in de klassieke witte recuperatie watertonnen.
Doordat de tonnen wit en semi-transparant zijn, ontstaat er algengroei. Iemand raadde mij aan om een UV filter te plaatsen. Is dit de oplossing?
Blijkbaar niet, vwant het water moet dan continu door de filter heenstromen, anders komt de algengroei weer.
Eventueel de tonnen zwart verven, of inpakken met opaque plastic.
Een filter plaatsen nadat het water door de pomp gegaan is.

Tonnen ingepakt met anti-worteldoek zodat ze afgeschermd zijn van het licht ter voorkoming van draadalgen vorming. Grote filter geplaatst na kraan na pomp (01/10/2012). Toevoer aangebracht in de serre. Vandaaruit 4 circuits gelegd, met op elk circuit nog eens een extra filter en druk(bar)controle: 1 voor de serre en 3 buiten.

AIR pollution monitoring

The purpose is to gather data on the effects of urban air pollution on urban gardening- and farming crops. Soil can be analyzed and heavy metals in soils can be treated by bioremediation (mushrooms, green manure, nitrogen fixers), but on the effects of city air pollution on crops there is not a lot of information available.
How do car exhaust, road dust and acid rain affect the different crops? Is the environmental pollution affect different for leaves, flowers, roots or fruits? Are nuts, fruits and berries less exposed to the urban pollution risks than leaf crops as spinach, or as root crops which do take up and accumulate metals from dust particle deposits in the soil?
How might we intelligently assess risk and proceed with a program of harm reduction, and modify urban garden design strategies around these known risks?

Field research could be:
- how long does particle dust stay on a tomato skin in your urban garden? Does the tomato absorb it or does it wash off in a rain? What about raspberries, blueberries, hazelnuts? What about different herbs? What about beetroot and lettuce?
- compare the data gathered from urban environmental pollution monitoring on organically grown vegetables, with monitoring data of non-organically grown vegetables of industrial agriculture origin (pesticides, GMO's, chemical fertilizers, … )

research papers:
Secondary organic aerosol formation from anthropogenic air pollution
Effect of air pollution on peri-urban agriculture: a case study

sensors for monitoring:
- air pollution meter : air quality (optical→dust, O3, CH4, CO2)
http://sensorapp.net/?p=479 (optical dust sensor)
- carbon monoxide pollution meter
- lead pollution meter
- exhaust gasses pollution meter

Pollution is definitely a concern for city farmers, but luckily, the pollutants of greatest concern are heavy metals, such as lead, and automotive break pad particulates. Both are denser than air, so vegetables grown on a rooftop high above the roadways are protected from these contaminants. The limited lifespan of plants mean they absorb significantly less contamination than our lungs do.

09. the self sufficient garden : energetic skin

composting: with a little help of our friends

The self sufficient garden is not far away. With a little help from our friends, the insects and micro-organisms we can find in amounts of zillions in the garden compost heap, we can make microbial fuel cells which can power small devices (sensors) for monitoring the gardens.

http://pandora.okno.be/IL/editor/00:00:00,00:03:06
Microscope registration of the micro organism activity in a rooftop compost heap. The organisms are ± 1 mm long, there are zillions of it in the compost, the surface covered here is ± 5 square mm.
The organisms are extremely active, it would be great to convert their activity into energy to power the technology to monitor the rooftop garden. Cradle to cradle.

this is how to do it:
make magazine - bacteria battery

green roofs water management : the virtues of moss

A moss garden is a micro ecology. It tells a lot about the bigger ecological system it is part of. It acts in a way as a bio indicator. Moss is very resilient. How expansible is this resilience in city context?
Moss is also a source of inspiration for designing new materials. Bio mimicry.

moss on the roofs of the valldaura projectmoss on the roofs of the valldaura project

While green roofing is an accepted stormwater control technology, little is known about the quality of the roof runoff. In Phase I of this research, several green roof media (formed from commonly-used expanded minerals, stormwater filter media, and organic matter) were evaluated for their abilities to retain the pollutants from a synthetic acid rain. The samples were analyzed for metals, nutrients, and pH. The hypothesis was that a mixed media that is “better” at pollutant removal and permanent retention could be created based on these laboratory testing results. A media composed of expanded shale, granular activated carbon, and sphagnum peat moss was the most effective.

greenhouse on the rooftop

greenhouse, frontgreenhouse inside
The greenhouse in the rooftop UrbanFarm is for me the best discovery related to urban agriculture. When we talk in ways of yield and sustainable city agriculture, a greenhouse is the perfect solution.
It is an easily controllable mini ecosystem, protected from wind (on the rooftops this is an important factor for drying the containers and plants) and with its own humidity. The 'tropical ecosystem' it creates is much more ecological in use of water (a lot is in the air)and as a closed circuit it can also be controlled by sensors on the level of (too much) sun or UV, and fertilizers.

companion planting

Companion planting is the planting of different crops in proximity (in gardening and agriculture), on the theory that they assist each other in nutrient uptake, pest control, pollination, and other factors necessary to increasing crop productivity. Companion planting is a form of polyculture.
Companion planting is used by farmers and gardeners for many reasons. For farmers using an integrated pest management system, increased yield and/or reduction of pesticides is the goal.For gardeners, the combinations of plants also make for a more varied, attractive vegetable garden, as well as allowing more productive use of space.

Seeds (saving) ⇒ plants moving through time and space.
Drying following herbs and flowers as basic ingredients for herbalist preparations: macerates, creams, tinctures, oils, sirops, …

  • Rosmarinus officinalis - rosemary
  • Thymus vulgaris - thyme
  • Eucalyptus gunnii - eucalyptus
  • Agastache foeniculum - agastache
  • Salvia officinalis - sage
  • Origanum vulgare - oregano
  • Mentha piperita - peppermint
  • Hyssopus officinalis - hysop
  • Satureja montana - savory
  • Matricaria chamomilla - chamomile
  • Viola tricolor - heartsease
  • Calendula officinalis - calendula

Calendula doet het uitzonderlijk goed, zowel op de teelaarde als op de lavagrond. Ze is een ideale companion voor andere planten en groenten. Er zijn geen ziektes geweest in de tuin in het seizoen 2012, geen bladluis - enkel een heel klein beetje einde zomer, op de Calendula zelf die als aantrekker fungeert. Direct de besmette planten wegknippen gaf zeer goed resultaat, luis is ook verdwenen.
Hoe meer men de Calendula plukt (voor drogen voor maceraten), hoe meer bloemen er verschijnen. Bloemen vanaf mei tot eind oktober/november, afhankelijk van weersomstandigheden.
De geoogste zaden zijn veredeld en aangepast aan de habitat van de daktuin, het jaar erop zouden de bloemen dus nog beter moeten gedijen.

Opened the hive#1 (december 18 2012) to check broken sensor. Bees still alive, cosy and warm in the hive. Temperature was rising instantly when opening.
Discussed with Antonio which sensors to change and how. Try to stabilize the platform and link the data to the smartcitizenmap BCN.

14. other animals

carrion crow : http://en.wikipedia.org/wiki/Carrion_Crow
The carrion crow is generally solitary. The most distinctive feature is the voice. The deep-noted croaked kraa is distinct from any note of another bird. The Carrion Crow is noisy, perching on the top of a tree and calling three or four times in quick succession, with a slight pause between each series of croaks. Like all Corvids, Carrion Crows are highly intelligent, and are among the most intelligent of all animals.
Though an eater of carrion of all kinds, the Carrion Crow will eat insects, worms, grain, small mammals, and scraps and will also steal eggs. Crows are scavengers by nature, which is why they tend to frequent sites inhabited by humans in order to feed on their household waste. Crows will also harass birds of prey or even foxes for their kills. Crows actively hunt and occasionally co-operate with other crows to make kills.Crows have become highly skilled at adapting to urban environments.

the family Blackbird (man, wife and kids) : http://en.wikipedia.org/wiki/Common_Blackbird
The Common Blackbird is omnivorous, eating a wide range of insects, earthworms, seeds and berries. It feeds mainly on the ground, running and hopping with a start-stop-start progress. It pulls earthworms from the soil, usually finding them by sight, but sometimes by hearing, and roots through leaf litter for other invertebrates. Small vertebrates such as frogs, tadpoles and lizards are occasionally hunted. This species will also perch in bushes to take berries and collect caterpillars and other active insects.[25] Animal prey predominates, and is particularly important during the breeding season, with windfall apples and berries taken more in the autumn and winter. The nature of the fruit taken depends on what is locally available, and frequently includes exotics in gardens.

rock dove : http://en.wikipedia.org/wiki/Rock_Dove
Pigeons feed on the ground in flocks or individually. They roost together in buildings or on walls or statues.Its habitat is natural cliffs, usually on coasts. Its domesticated form, the feral pigeon, has been widely introduced elsewhere, and is common, especially in cities, over much of the world. With only its flying abilities protecting it from predation, rock pigeons are a favorite almost around the world for a wide range of raptorial birds.In fact, with feral pigeons existing in most every city in the world, they may form the majority of prey for several raptor species who live in urban areas. The birds that predate pigeons in North America can range in size from and can even include gulls, crows, and ravens.

feral pigeon : http://en.wikipedia.org/wiki/Feral_Pigeon
Feral pigeons (Columba livia), also called city doves, city pigeons, or street pigeons, are derived from domestic pigeons that have returned to the wild. The domestic pigeon was originally bred from the wild Rock Dove, which naturally inhabits sea-cliffs and mountains. Rock (i.e. 'wild'), domestic and feral pigeons are all the same species and will readily interbreed. Feral pigeons find the ledges of buildings to be a substitute for sea cliffs, have become adapted to urban life, and are abundant in towns and cities throughout much of the world. Pigeons breed when the food supply is abundant enough to support embryonic egg development, which in cities can be any time of the year. Laying of eggs can take place up to six times per year. Pigeons tend to congregate in large, often thick flocks when feeding on discarded food, and have been observed flying skillfully around trees, buildings, telephone poles and cables, and through moving traffic just to reach a food source.
