When cities try to relocalise food production, they should keep in mind that it is not only the number of hectares of land that is relocalised that counts. They also need to take into account the quality of that land. More widely, they need to familiarize themselves more with the farming sector in order to provide suitable conditions for farms to come back close to the cities.
