The policy says nothing at all about more or less people in the cities. Though more is pretty much inevitable.

If more people live within walking distance of the office, obviously you will have less congestion than if they have to commute 20km.

Designated park areas are to be assigned where residents or council may plant food trees. These differ from conventional 'community gardens' in that they are intended to be for trees rather than intensively managed vegetable patches, are intended to be close to people's houses so that they do not have to drive to them, and are intended to be mixed use open space, not fenced off. Council may limit the number of each species of tree, may limit the permitted species to short ones, or may trim the trees to limit height and size (to make fruit such as mangoes easier and safer to access, and to prevent dominance of one tree over a large area). The trees are to remain communal property and no limitations are to apply as to who may pick the fruit, though guidelines may be applied to the quantity taken, and the fruit may not be sold or passed on to a different household. Any expectation of personal ownership or reward for effort is to be discouraged. Use of some fruit may be restricted to immediate, onsite consumption in order to promote sharing or more popular food. However, this is not intended to prevent the picking of unripe fruit such as mangoes - this is in fact encouraged to prevent waste and pest incursions. The parks are to provide a space for the dumping of green waste to be used as mulch.

Councils are encouraged to use the parks as an opportunity to inform the public of the range of food trees that can be grown in the area and to supply seeds for planting at home (eg, with clear labeling of trees). The inclusion of species that are not well known locally or unpopular commercially due to transport and handling difficulties is particularly encouraged. A 'use it or lose it' policy may be applied, whereby trees are removed if the food is left to rot. The food parks are intended to provide an opportunity for social interaction as well as food. Authority and management responsibility may be handed over to local clubs, provided that these basic guidelines are complied with.
