Answer:
Correct Answer is: from an agricultural to an industrial society
Explanation:
North Korea tradition is strongly related to the agriculture, before the Korean War in 1950 that divided the region into North Korea and South Korea, the agriculture was the main economic sector with almost 64% contribution to the Economy.
After World War II they started to adopt the Communist economic system ( North Korea was a Soviet ally and South Korea was USA ally) and with it the Heavy industry related to Iron and Coal mining.
Because of this the agriculture decreased exponentially and passed from 64% to 26.8% in 1990. The low investment in agriculture meant no innovation could be made in this sector, because of the North Korean landscape (Mountanuos and few flatlands) there is a need on irrigation systems to be able to expand the yields and not needing to farm in the same soil over and over, by 2004 this investment was not made and almost 50% of the soil became degraded because overexploitation, this combined with heavy floods and political negligence resulted in a critic decrease on food supply.
For a country whose goal is to be self-sufficient, agriculture must be a top priority, and since 2013 there have been reports of a strong investment in this sector.
