Natalie Jeremijenko: The City as a Participatory Ecology Lab

Turning your city into a participatory ecology lab is the programme of Natalie Jeremijenko, the Australian artist, engineer and environmental scientist who directs the Environmental Health Clinic at New York University, and whose devices make pollution, biodiversity and the relationships between humans and other species visible so that citizens can investigate and change them. A sensor detects on a street what our eyes cannot see, a nearby device turns that information into a public experience, and pollution stops being an abstraction. Her question is what changes when residents can directly investigate the environmental problems of their city, and her answer is that observation becomes participation and the city becomes an open laboratory.

Making the invisible perceptible: Feral Robotic Dogs

The mechanism begins by making perceptible what usually stays hidden. Pollution can exist without giving a clear signal to someone crossing a street, and ecological relationships disappear from attention inside the built landscape; sensors, robots and other devices register or represent those conditions, and then information leaves the expert setting and enters public experience. Her Feral Robotic Dogs of 2002 were cheap toy robots hacked to sniff out contaminants and released in packs on suspect sites, so that children and neighbours followed them across the ground and saw where the pollution was, producing data that agencies had not collected and questions they had to answer.

The Environmental Health Clinic and talking to the river

The Environmental Health Clinic, opened in 2007, inverts the medical model: instead of coming with a symptom and leaving with a prescription, visitors come with an environmental concern and leave with a prescription for action, planting, monitoring, redesigning a space. Her projects on biodiversity follow the same logic. Amphibious Architecture, installed on the East River in 2009, used floating tubes with sensors and lights that responded to water quality and to the presence of fish, and let passers-by send text messages to the river and receive replies; the Mussel Choir turned the opening and closing of mussels, which filter water, into sound that reported pollution in real time.

Coexisting with other species: the Tree Office and urban biodiversity

That second family of works changes the environmental question. We no longer ask only how to protect nature somewhere beyond the city, but how humans coexist with the forms of life already present in everyday urban space: fish under the piers, birds on rooftops, trees in pavement pits. Jeremijenko's Tree Office, a workspace built around a tree in a Manhattan park, or her Butterfly Bridge and urban farming prototypes make that coexistence a design problem, and engineering becomes a tool for paying attention to relationships that ordinary urban perception leaves out.

Participation, its limits and what visibility changes

Participation is the third element. A device enters an urban space and citizens interact with it, generating knowledge about an environmental condition while changing how they observe the place; the experiment happens in the same territory as the problem, and people take part while using the city. That distinguishes her work from citizen science that only collects data for experts: the point is to alter who recognises a problem and who feels entitled to act on it. The irony she cultivates is that a small, playful device can make visible an urban issue that large institutional systems keep distant.

The counterargument matters. A sensor, robot or artistic intervention does not solve pollution or biodiversity loss by itself, producing information does not guarantee that institutions or citizens change behaviour, and participatory technology can become an alibi for the absence of regulation and public infrastructure. Jeremijenko does not claim otherwise: her devices enable experimentation, knowledge and participation, and making a problem visible is not the same as solving it. But visibility changes who recognises the problem and who demands action, and that shift, from residents as objects of environmental policy to residents as investigators of their own surroundings, is the lesson her participatory ecology lab offers to any city.
