	'''Pastures''' - Land used for grazing livestock or growing feed for them.		'''Pastures''' - Land used for grazing livestock or growing feed for them. The USDA Cooperative Extension service lists tables of acreage required in terms of "Animal Units" equal to one 1,000 lb cow, and land productivity in units of tons/year of dry matter, which is highly variable. The species listed are very limited (cows and sheep), so consider other animal food sources (chicken, fish, etc). Turning plant matter into meat is always inefficient, so consider minimizing meat use if diet preference and nutrition allows.

	Facilities includes land, buildings, and outdoor modifications/additions. Generally items permanently attached to the ground are included as facilities. A device such as a wind turbine could also be counted as equipment, so the distinction is somewhat arbitrary. The important thing is to only list a given item in one place, and track the flows going in and out of it.		Facilities includes land, buildings, and outdoor modifications/additions.

The important thing is to only list a given item in one place, and track the flows going in and out of it.

	Total land required is based on the total number of people, what percentage of their needs the land will support, the productivity and geology of the land, and land needed for individual buildings and other facilities. An allowance for future expansion may be included. Not everything can be built at once, so time phased use of land should be considered. For example, an area may be used for an outdoor garden at first, and later converted to a more productive greenhouse. Mixed or multiple use land should also be considered.

	If we assume 2% growth and 1% maintenance after initial construction, we need 135 board feet per person/year or 3.5 acres per person to be sustainable. This does not count initial construction. This seems high, so there are several ways to reduce the number. Sawtimber only counts the parts of trees over 10 inches in diameter and 8-12 feet long, ie useful for commercial loggers. You can use more of the tree, or smaller trees. Average land is not "fully stocked", meaning having enough trees to fully use the light that falls on it. So selecting fully stocked land or planting additional trees can increase the growth. The vast majority of forest land is not fertilized like field crops. Trees respond to fertilizer like any other plant. Finally, a house can be built using less wood.

	'''Crop Fields''' - Land primarily used for growing field crops		'''Crop Fields''' - Land primarily used for growing field crops. For estimating purposes the following chart can be used and compared to the calorie needs for the number of people. Field crops require a lot of land area, mechanization to grow efficiently, and is highly competitive in the developed world. So strong consideration to alternatives to having them be the primary internal food source should be made. Having said that, each person needs 876,000 kCal per year. Allowing for spoilage and waste, assume 1 million kCal harvested. The field crops in the chart below average 6 million kCal per acre, so if they provided all food calories (which is not nutritionally sound), then 1/6 acre per person would be required. The difference between that number and the 3 acres farmland per person in the US is due to variable land productivity, feeding some crops to animals, and not using 100% of land area for crops.
