Availability information for this program

The First Agricultural Revolution was the transition from hunting and gathering to planting and sustaining. The Second Agricultural Revolution increased the productivity of farming through mechanization and access to market areas due to better transportation. The Third Agricultural Revolution known as the Green Revolution refers to the introduction of high yielding genetically modified seeds and increased use of fertilizer and irrigation methods. Now a fourth agricultural revolution is taking place as a result of big data and artificial intelligence. Seven experts from prominent agricultural research universities describe how these dramatic changes are impacting food production.
