I would think it would be any of the third world countries in the world...African nations come to mind. Perhaps Haiti, or other Island nations would be in the running. North Korea would also have to be up there since they have a long and difficult history.
I would also argue for Zimbabwe if your question is to be interpreted as the first two posts did. While North Korea has long been plagued by famine and other food-related woes, in recent years their food situation has improved. Their crops have been producing more, thanks mainly to help from China and other countries that bypass sanctions, and recent footage from the country demonstrates that the population looks healthier than they did during the widespread famine of the 90s (that has to be taken with a grain of salt, though, since North Korea controls almost all information that comes out of the country).
Zimbabwe, on the other hand, has been wracked by corrupt leaders, unbelievable inflation, and poor food production. It is difficult for other nations to get supplies to those who need it most in the country because of the corruption at all levels of government.
I assume you mean in actuality, not in literature as your question tag suggests. There are many countries that could compete for this grim title, but North Korea would have to be near the top, since they have suffered from food shortages and famine for literally decades. A lack of reliable energy imports means they have little to produce food with.
Since they live under a ruthless dictator, Kim Jong-il, there is very little international trade as most countries refuse to do business with him. What little hard currency the country has goes to maintaining a massive military and a nuclear weapons program. As many as 100,000 North Koreans die each winter from malnutrition, and the average North Korean is four inches shorter than the average South Korean.
The Sudan, Somalia, Chad, and Zimbabwe could also make the list.
Right now I would have to say either Haiti or North Korea. The world food programme of the UN lists countries that have particular food hunger needs and those countries are at the top of the lists.
That question is easily skewed passed on perspective. If your question is which Nation currently has the least food stockpiled the answer varies. Your question could be interpretted as, which nation has at any given time the least amount of useable food the answer could very easily vary as equally as any other interpretation.
Haiti for example is not a high pick for "least amount of useable food" but is an appropriate choice for "the least food stockpiled."
Bulawayo (Zimbabwe) – Crisis-hit Zimbabwe faces its worst food shortages yet with this year’s harvest expected to meet only 30 to 50 percent of national requirement, according to the Famine Early Warning System Network (FEWSNET). FEWSNET is a United States Agency for International Development (USAID) network for monitoring hunger, food availability and shortages across the globe. In its latest food outlook report on Zimbabwe covering the period from March to July 2007, the network said widespread crop failure caused by poor rainfall and a long running economic crisis had combined to drastically slash food production in the southern African country
