Vertical farming will likely be needed by the second half of the century. By 2050, the world is estimated to need to feed over 9 billion people, with 70% of people living in urban areas. At some point we will reach a tipping point where the arable land available is insufficient for the growing population. Given the potential of building upwards, the yield could be much higher than with regular soil-based farming. Setting up an Institute for Food Innovation, with early-stage funding allocated, would help get new industries and technologies off the ground.
