Growing on private land
Allotments v Public land v Private land - Bear in mind that allotments are fenced, but you can't sell the produce. Growers on council land may sell their produce but perhaps not fence their plot. But if you grow on private land (your own, a friend's or maybe someone like Yorkshire Water or a school) - you may be able to do both - if you want to. See Ownership
If you're looking to grow on private land that you don't own, you will need to find out who owns it. The sure-fire way to do this is to pay a £30 fee to the Land Registry http://www.uklrs.co.uk/land-registry/ then click on Land Registry Searches. (You may want the section titled "Title Register & Title Plan for Land not having a full Postal Address").

Once you know who own the land, you have three basic options.
1) Informal: Borrowing / sharing land
2) Formal: Renting, leasing or purchasing land
This gets a lot more complicated, so we're not giving detailed advice here ourselves. The Federation of City Farms and Community Gardens https://www.farmgarden.org.uk/farms-gardens/your-region/north-england can support you in identifying and accessing land for a variety of projects (including training for buying the land). They are also the initiator of the Land Access Advisory Service, which offers documents for download and workshops, or can provide specific advice.

3) Temporary: 'Meanwhile' use, Squatting, and Guerrilla Gardening
• 'Meanwhile' use
This just means temporary use, and here we're assuming you'll be getting permission from the landowner. (Feed Leeds would not wish to encourage any use of land which would antagonise or deliver negative publicity for community urban agriculture).
There are lots of good reasons for establishing a temporary project - maybe it's just too good an opportunity to miss, or maybe it's a way to get a group together which can then move elsewhere when the plot is reclaimed by the developer or whoever. 'Meanwhile' sites often use movable planters, for obvious reasons, but they can also leave behind a productive legacy such as seeds in the soil, bees and fruit trees.

Land squatting is a bit more permanent, and is essentially the same as squatting a building. The official line is that it "isn’t in itself a crime, but trespassers on non-residential property may be committing other crimes. It’s normally a crime for a person to enter private property without permission and refuse to leave when the owner asks." So in theory, temporary land squatting might be made to work, as long as you're prepared to leave if asked.

Squatting takes us into the more political issue of common rights.

• Guerrilla Gardening
This might be applied to any of the above, and it works on the principle that it can be easier to get forgiveness than permission (as Incredible Edible Todmorden proved across a whole town)! It usually involves growing on small patches of unused public land, and usually with a 'help yourself' harvesting policy.
