Vertical Agriculture (YPGN)

Vertical Agriculture (Vietnamese: nôngnghiệp teochiềuyọc) is the primary form of agriculture in the Grand Yarphese Republic.

History
The idea of vertical agriculture for use in Yarphei was first devised by Vietnamese-American economist Hô Yăng Nhịp in 1993. He proposed that its implementation would make production far more efficient. While Yarphei was already a major producer of rice, Nhịp suggested Vertical Agriculture would be likely to prevent food shortages as well as take advantage of the limited area.

Vertical agriculture was not implemented until following the failure of the Yarphese Plan in the late 1990s. It was decided that due to the starvation rates in areas such as Bangkok and Sinapore, there needed to be an effective way to provide food to the cities.

The first experimental vertical agriculture building was built on Tekong Island, Singapore. The main produce was rice. Since then, Vertical Agriculture has played a paramount role in Yarphei's economy. Despite the expensive startup costs, vertical agriculture has, in addition to allowing Yarphese corporations to compete overseas, it has significantly reduced poverty and food costs, and cut down on food distribution costs. Many large supermarkets today have on-site plants.

Operation
Currently hundreds of vertical agriculture facilities exist around Yarphei. There are two principal types: one meant for areas which require a controlled climate, and an open-air version for tropical regions. Both share the same general structure.

Vertical agriculture facilities are usually composed of several flat planes on which plants are grown. They are placed parallel and at angles, either horizontally or vertically. Lenses are used to refract light onto the plants evenly. Each plane is hollow, and contains the plants' roots. Yarphese Weather Control technology is used to create a high-pressure mist to inject water and nutrients into plant roots.

All vertical agrculture is powered by concentration of the sun's rays onto the pipes that bring mist to the plates. This results in a circulation of air that provides a continuous supply of mist to the plants. MQB Weather Control is powered by turbines that utilize this flow of air. Backup lighting through the night is accomplished using hydroelectric power from runoff in tropical areas or an alternate fuel elsewhere.
