Research indicates greenhouse gas emissions would rise if all farms in England and Wales went organic as a result of increasing food exports to compensate for the low organic yields.

According to the analysis, for wheat and barley, organic farmers only yield half compared to conventional farmers, meaning 1.5 times more land would be required to grow the same amount of produce.

Laurence Smith from the Royal Agricultural University in the UK who was involved in the analysis says organic farming has a greenhouse gas problem that can’t be ignored.
