Perspective: What might it cost to reconfigure food systems?
Even an approximate estimate of the amount of investment required globally to reconfigure food systems for resilience and sustainability in the face of climate change could help to catalyse the urgent action that is needed. A report published in 2020 set out eleven actions that were identified as being needed to reconfigure food systems. Here we estimate the annual cost of implementing these eleven actions to be USD 1.3 ± 0.1 trillion.
