North Korea's total grain production last year reached its highest level since the country's economy began its collapse in the mid-1990s.

According to the World Food Programme and the Food and Agriculture Organization, the North produc ed nearly 5 million tons of rice, corn and beans in 2014, an increase of 130,000 tons from a year earlier.

While data from the UN bodies show that the regime's food production has gradually increased since leader Kim Jong-un came to power in 2011, North Korea is still not self-sufficient, lacking the bare minimum of grain needed to feed its people.
