The 9th International Markets Conference was held in Barcelona 26-28 March and was hosted by the Project for Public Spaces – this link also has a good article on Barcelona as part of PPS work on Market Cities. The conference sounds a great success and there is a blog posting from Foodshare, Toronto with a few thoughts about indoor v outdoor markets and their own work with getting fresh produce to low income communities here.
No doubt more reports will follow.
I want to draw your attention to the US Project for Public Spaces (in the blog roll). Founded in 1975, this is a nonprofit planning, design and educational organization dedicated to helping people create and sustain public spaces that build stronger communities. The website has a section about projects with a variety of US markets (see here: http://www.pps.org/projects/project-categories/markets-projects/ ). There is also an international initiative, run in collaboration with UN Habitat – you can read about the Future of places here.
