Foodshed
The “farm-to-table” movement is focused on producing food locally within a foodshed, and delivering it to local consumers. Direct farm-to-table in the United States tends to comprise only a very minor segment of the food distribution system in terms of size and importance, but is growing in popularity.Nearly 5 percent of all farmers engage in some form of direct food marketing. Estimates of all farm-to-table sales within a foodshed range from roughly $550 million to $2 billion. Many local farms are family-run farms that are successful and do survive through poor economic conditions. Ecologists consider to be more adaptive and more likely to “reproduce” in highly variable and uncertain environments.
Vertical farming
Vertical farming is the practice of producing food and medicine in vertically stacked layers, vertically inclined surfaces and/or integrated in other structures (such as in a skyscraper, used warehouse, or shipping container). The modern ideas of vertical farming use indoor farming techniques and 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 greenhouses, where natural sunlight can be augmented with artificial lighting and metal reflectors.
