<\/a><\/p>\n“At the time of the Spanish conquest, the Incas cultivated almost as many species of plants as the farmers of all Asia or Europe. On mountainsides up to four kilometers high along the spine of a whole continent and in climates varying from tropical to polar, they grew a wealth of roots, grains, legumes, vegetables, fruits, and nuts.<\/p>\n
Without money, iron, wheels, or work animals for plowing, the Indians terraced and irrigated and produced abundant food for fifteen million or more people\u2014roughly as many as inhabit the highlands today.<\/p>\n
Throughout the vast Inca Empire, sprawling from southern Colombia to central Chile\u2014an area as great as that governed by Rome at its zenith\u2014storehouses overflowed with grains and dried tubers. Because of the Inca’s productive agriculture and remarkable public organization, it was usual to have 3\u20137 years’ supply of food in storage.<\/p>\n
