Decentralization of food production would allow for a reduction in transport costs and would preserve the freshness and nutritional value of our food and eliminate the need for harmful preservatives, energy-expensive refrigeration and food storage. However, traditional methods of decentralized food production are rather labour-intensive. For many people, growing their own food is a very enjoyable and rewarding sort of labour that they willingly devote their energies to. Others would like the option of avoiding this labour. For those folk, it is now possible to automate food production (see below).</del></div></td><td class='diff-marker'>+</td><td style="color:black; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div>{{<ins class="diffchange diffchange-inline">:Food/Intro</ins>}} {{more|<ins class="diffchange diffchange-inline">Food</ins>}}</div></td></tr>

Estimates of how much land is required to grow a person's food vary, but 60-100 square metres seems reasonable, using modern techniques of organic permaculture. (That means you could grow enough food for 4-7 people on an area the size of a basketball court.) This is fine for rural and semi-rural people, but in cities with high population densities, it would be desirable to reduce this.</del></div></td><td class='diff-marker'>+</td><td style="color:black; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div></div></td></tr>

Unlike ordinary lightbulbs, LED panels can be designed to emit a full spectrum of light, which is what plants need to grow. LEDs could be useful in situations where sunlight is unavailable - such as in winter in regions far from the Equator, in underground or underwater dwellings, in cities where a demand for space means food must be grown on stacked shelves indoors, and in space stations. Currently the main obstacle to large-scale controlled environment agriculture projects such as [http://www.verticalfarm.com/ The Vertical Farm Project] is the cost of energy needed to provide the light. As LEDs become cheaper and more energy-efficient (as with recent developments in OLED and PHOLED technology) this sort of production of high-quality food is becomes more and more feasible. </del></div></td><td class='diff-marker'>+</td><td style="color:black; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div></div></td></tr>

Also, controlled environments eliminate the dependence of food production upon the cycles of the season, allowing food to be grown all year around.

<p><b>New page</b></p><div>The decentralization of food production is becoming more and more possible as technology and knowledge grows. Decentralization of food production would allow for a reduction in transport costs and would ensure freshness of the food people eat, which increases its nutritional value and eliminates the need for energy-expensive refrigeration and food storage. However, current methods of decentralized food production are rather labour-intensive. It may be possible to automate these processes (see below), but for now centralized food production requires much less human labour to produce an equivalent amount of food.<br />
<br />
If food production is to be decentralized, land use becomes an issue. Estimates of how much land is required to grow a person's food vary, but 60-100 square metres seems reasonable. That means you could grow enough food for 4-7 people on an area the size of a basketball court. In cities, food could be grown under LEDs on stacked shelves, cutting this space to a fraction of that number (e.g. if there were four shelves stacked on top of one another, 15-25 square metres would be needed). <br />
<br />
===Aquaculture===<br />
[http://www.thegreencenter.net/ The New Alchemy Institute] did a lot of research into aquaculture - small scale production of fish for eating. They found that a fish tank five feet in diameter and five feet tall can produce forty pounds of fish a year. (Meaning that you could have fish for dinner twice a week.) Ron Zweig developed a method in which the fish tank doubles as a source of hydroponic vegetables - the fish fertilize the plants, the plants clean the water, and both can be eaten by humans.<br />
<br />
The New Alchemy Institute developed computer algorithms which could accurately predict the yield of fish based on variables[www.thegreencenter.net/pdf/solaraqua.pdf]<br />
<br />
Algae could also be grown on the surface of the water, providing a source of food for the fish so that they would not require feeding. Many species of algae are also edible by humans.<br />
<br />
===Automation===<br />
Because of the high amount of time and labour needed for traditional farming methods, it is worth looking for something easier and more automated.[[Image:Hydroponics.jpg|right|300px]]<br />
<br />
Hydroponics is the growing of plants in a nutrient solution rather than in soil. This allows for precise control of the amount of nutrients that the plants receive. The figures on {{wp|Hydroponics#Higher_Yields|Wikipedia}}, show that hydroponics yields represent an increase on normal growing techniques of about 50% to over 1700%. The precision of control over the growing medium also lends itself to automation more readily than does growing in soil.<br />
