This weekend, Bogota, Colombia will launch its second 100en1día (100 in 1 day) event, a blitz of urban interventions meant to multiply the impact of citywide citizen activism exponentially. Cities across the world are following their lead.
"There’s a limit to the amount of physical change one person or a small group of people can initiate in a city, but what if hundreds of citizens united, each putting in place the projects and changes they want to see in their city all on the same day? That’s the goal of 100en1día (100 in 1 day) – a social movement originating from Bogotá, Colombia, which aims to inspire citizen driven change on a significant scale, transforming cities over a 24 hour period," writes Joe Peach.
"The project has already encouraged hundreds of interventions in the Colombian cities of Bogotá, Pasto, Pamplona and Chinú, with street art, urban gardens and bike lanes all appearing on the same day. Bogotá is currently preparing for their second event on the 27th of April and international cities are also beginning to get on board. San José is launching its first event on the 20th of April and Cape Town and Copenhagen are running their own versions on the 25th of May."
