The UN is pushing "smart crops" like millets, sorghum and beans as an alternative to rice in Asia to tackle hunger, according to the head of the UN's Food and Agriculture Organization in Asia. Smart crops are more nutritious than rice and adaptable to climate change. A campaign aims to promote smart crops and change perceptions of them as "poor people's food" to "smart people's food." Government policies are needed to promote affordable diverse diets beyond a heavy reliance on rice.
