Mapping Your City's Smells
What can we learn from pausing, deeply inhaling and smelling—yes, smelling—our cities? A new paper from University of Cambridge researchers argues that while urban planners and policymakers have a lot to say about road diets, the sharing economy, and housing policy, too little attention has been paid to urban smellscapes, those scents that emanate from and so influence urban life.
So the scientists, led by researchers Daniele Quercia and Kate McLean, got to work. First, they took local volunteers on a series of “smellwalks,” jaunts around seven global cities during which participants identified distinctive urban smells. From this exercise, the researchers created a comprehensive urban smell dictionary, including less pleasant odors (“exhaust,” “manure,” “trash,” “putrid,” and “vomit” among them) and downright lovely-sounding ones (“lavender,” “fruity,” “BBQ,” and “baked,” for example).
