In Leviticus chapter 25 verse 21 God commanded His blessings upon the crop production of Israel, if they obeyed Him. He would enable them to have a seventh year of rest in which no crops were sown. In obedience, to His agricultural laws, they would have sufficient grain for the next three years. Every country, on earth, that has arable land, should be able to produce an abundance of crops so as to satisfy the food needs, of that nation. Only food that can not be grown easily, in their country, because of its specific climate specifications, should have to import any food. However, to do so, each nation must be willing to follow God's guidelines. Herein lies the agricultural problem, for most nations.
