Vertical farming is great for growing lots of food in a small space, but productivity comes at a cost: high energy use.Read More
Led by ASU and Google, the study assesses the value of urban agriculture and quantifies its benefits on a global scale. While most of the benefits from these efforts seem to be limited and very local, when taken collectively the result is a significant environmental impact.Read More
Growing crops in controlled environments – in greenhouses, plant factories and in vertical farms – provides alternatives to conventional farming by producing food year-round near metropolitan areas, reducing transportation costs and water use, and improving land-use efficiency. Such local systems also offer valuable educational and psychological benefits by connecting urban people to the food they consume.
At the same time, there is little concrete evidence to show how so-called controlled-environment agriculture (CEA) compares to conventional field agriculture in terms of energy, carbon and water footprints, profitability, workforce development and scalability.Read More
