With an anticipated expansion in demand for food in urban areas due to the world’s growing urban population, urban agricultural innovations are portrayed in this article as possible solutions. Aeroponic farming systems are one example: these systems allow for clean, efficient, and rapid food production. The crops, which protected from seasonal changes in weather, can be planted and harvested year round without interruption and without contamination from soil, pesticides, and residues. Because aeroponic growing environments are clean and sterile, the chances of spreading plant disease and infection are less common than in soil-based systems.
The article also argues that such systems can deliver the following benefits: produce does not require washing after harvest; can be delivered fresh to stores and restaurants on a daily basis; has a shelf life of 3 to 4 weeks; offers year round seasonality; has a faster growth cycle; and does not need to be treated with pesticides.
