Can urban vertical farming be the next frontier in achieving sustainable food systems?

As urban populations swell and arable land becomes more scarce, traditional farming methods face significant challenges in meeting global food demands sustainably. Vertical farming, which involves growing crops in stacked layers, often indoors, using soil-less methods like hydroponics or aeroponics, is emerging as a promising solution. This method not only maximizes space and conserves water but also reduces the carbon footprint associated with transporting food products. However, questions remain about its scalability, energy consumption, and economic viability. As cities look toward sustainable practices, is vertical farming equiped to play a key role in creating resilient urban food systems?
