 *These a edible food crop yields.  The actual average biomass crop yields are at least double these.  Potatoes are about 80% edible yield while most plants are between 35% and 50%.

 Meat production may someday be artificial, but may for some time come from [[animals]].  Vegetable alternatives exist for meat,  and usually require less energy for their production.  Therefore producing meat may be a question of demand and opportunity, rather than a question of need.  Animals can produce meat from unused biomass, but the demand for other uses may be higher than the demand for meat production.

 Using hydroponics and greenhouses or vertical farms, an average yield of 60 tonnes per hectare per year should be possible (ref).
 This corresponds to a yield of 6 kg/m2/y.  If the average illumination is 250 W/m2, then the average energy required for food production is:
 *250 W/m2 x 24 x 365 x 3600 / 6kg/m2 = 1300 MJ/kg

 *The value of 180 m2 per person is the minimum area with high intensity lighting required to produce the minimum amount of food for one person.
-*In other units, 10 000 m2 (one hectare) / 180 m2 = 55.  So one hectare intensive agriculture can feed up to 55 people, per year.

 *Higher densities can be obtained using hydroponics and shelves or higher levels of lighting and optimized fertilization.  This may  not be sustainable in normal soil.
 *Using animals to produce protein would increase the area required, while fish may combine habitats with plants for a null impact on total area.
