Populations are growing and cities are booming – but could we soon see skyscrapers turned into centres for crop production? From Chicago warehouses to the south pole growth chamber in Antarctica, the concept of growing food indoors is catching on. Plant scientist Dr Erik Murchie, from the University of Nottingham, reveals how agriculture could be turned on its head.
Could this be the solution to the growing demand for food?
Cities could become almost completely self-sufficient; they have the opportunity to produce both food and energy.
More recent studies show that food system emissions could account for as much as quarter of all human emissions. That is 12% from agricultural production, another 9% from farming induced deforestation, and a further 3% from things like refrigeration and freight.
