Governments need to consider stepping up research into perennial crops. Experts suggest that 'moving back to the future' to these kinds of multi-year crops with deep roots can also boost soil fertility and stability 50-fold while assisting in adapting to climate change.
Perennial crops are also 50 per cent better at carbon capture and storage than their annual cousins, according to some estimates.
Because they do not need to be planted every year, they use less farm machinery and require fewer inputs - reducing greenhouse gas emissions further.
