Hi Tiffany, I'm no expert, but I'm wondering whether what you mean by allotments is similar to community gardens? There's apparently over 110 community gardens in Vancouver according to the City (https://vancouver.ca/people-programs/community-gardens.aspx). There is also this Community Garden Builders site (https://www.communitygardenbuilders.com/) which lists some garden locations that they manage and allows you to sign up to the respective wait lists. Some gardens have their own websites and distinct policies (for instance, plots are available at Strathcona Community Garden, but you're obligated to be part of a work party and sign up in person: http://strathconagardens.ca/). For your article, perhaps you might want to talk to people with some institutional memory of the 3-year program (now completed) called the Vancouver Community Agriculture Network. This was, according to their website, a successful collaboration between Tree City, Environmental Youth Alliance, PHS Community Services Society, and some UBC Land and Food Systems Faculty (https://vcan.ca/about-us/). Maybe you are already aware of these resources, but I hope this helps a little if not. :)
