The Community Council of Devon has assembled three 'toolkits' to help food groups across Devon with doing their thing.
You can find these handy sounding toolkits online, or read more information about some case studies on their site. Here's their press release:
As of today, groups across Devon who want to grow their own food will be able to get help from three new toolkits, launched by the Community Council of Devon (CCD) . The 3 toolkits, developed with help from the Soil Association  as part of the Community Supported Agriculture (CSA) project, cover Legal Tenure, Planning and Access issues and are intended to help communities when they set up new food growing projects
