The humble potato was cultivated during the Inca Empire and for thousands of years before. When Spanish conquistadors arrived in the 16th century, they encountered the potato and brought it to Europe.
Today it is grown almost everywhere and considered a top food staple along with rice, corn and wheat.
By the year 2050, the global population is expected to exceed 9 billion people. That means food production will need to grow by an additional 70 percent. Scientists and researchers are looking into new varieties of potatoes as one way to fulfill that demand.
CGTN correspondent Dan Collyns traveled to Potato Park in the Sacred Valley of the Incas to get the lowdown on this versatile vegetable.
