There is a very well-established network of volunteer groups – one for nearly every park, woodland and major green spaces in Leeds – some of whom are also involved with food growing (and more might be if asked nicely)! They meet at Feed Leeds’ sister organisation; the Leeds Parks and Greenspace forum. There is a full list of members on that website.
Growing Health is a national project to see how community food growing can be routinely used by the health and social care services as a way of promoting health and wellbeing.
