Vertical Farming

future of earth

Vertical farming, also called aerofarming and skyscraper farming, as a component of urban agriculture is the practice of producing food in vertically stacked layers, vertically inclined surfaces and/or integrated in other structures. The modern idea of vertical farming uses controlled environment agriculture (CEA) technology, where all environmental factors can be controlled. These facilities utilize artificial control of light, environmental control (humidity, temperature, gases,..) and fertigation. Some vertical farms use techniques similar to glass houses, where natural sunlight can be augmented with artificial lighting and metal reflectors. - Wikipedia

A vertical farm, 20 stories high and the size of a city block, would have the capacity to grow enough organic vegetables to supply a whole town.  There are plenty of positives. 24/7 crop production, no crop failures from  droughts, floods or pests.

The problem? The estimated cost of developing and maintaining such large scale urban agriculture, with its massive artificial lighting and hydroponic systems.

Obstacles to vertical farming could be overcome by technology. Vertical farms may be a good application for metamaterials, the new stuff scientists are creating that can bend light. Advances in solar cell technology, lighting, fiber optics, building materials and biotechnology could also make vertical farms more viable.
