Beyond the green revolution
There has been a substantial increase in food production over the last 50 years, but it has been accompanied by a narrowing in the diversity of cultivated crops. New research shows that diversifying crop production can make food supply more nutritious, reduce resource demand and greenhouse gas emissions, and enhance climate resilience without reducing calorie production or requiring more land.The Green Revolution – or Third Agricultural Revolution – entailed a set of research technology transfer initiatives introduced between 1950 and the late 1960s. This markedly increased agricultural
