The Conservation of Smellscapes

Recently, I cycled back late from town. There was no wind, almost no traffic, and no moon. I was struck by the power of smells in the dark: first some splashed diesel near the garage, then lilac in a garden, pine trees at the motorway bridge, and the warm ammonia of bullocks at the farm. Finally, home, and then, suddenly, the smell of my neighbour’s washing, hung out overnight: an overpowering and entirely artificial scent, a radical shift of smellscape.

I first came across the concept of ‘smellscape’ in a paper by the cultural geographer Douglas Porteus in 1985. He pointed out that smells tend to be place-related, and that the nose perceives smellscapes just as the eye sees landscapes.

Some caution may be warranted, for there are deceptive layers hidden by the term that are easily overlooked. Continue reading
