This is a weird title for what I would call the subscription food movement–you know, those home meal service delivery options like Blue Apron and Home Chef (2 options in my area) as well as local CSAs (community supported agriculture movements where you buy a share of a farm harvest for a season–although these are usually pick up).
I suppose perhaps community gardening might even fit this movement not because the garden comes to you–although it does, in a sense–but because of the education value of the garden. Back when I belonged to a community garden, we shared lots of things: advice about how to best manage pests (most gardens are organic), seeds and plant starts, extra produce and ways to prepare it and, at the end of the season, a community garden dinner. It truly was a “community” in every sense of the word.
The subscription services, on the other hand, while they might allow you to prepare dinner for others, are not generally communal in this nature.
And some CSAs can be this way, but not all are–it depends on the farm (although most will at least share ways to prepare what is in the harvest that week.)
I guess it is all up to the particular gardener–and how social he or she wants to be–to take advantage or this trend.
