Hawaiians used to feed themselves quite easily on this island paradise. With the arrival of Europeans and Americans came European and American ideas about plantation agriculture. Hawaii became a producer of coffee, sugar, pineapple, papaya, rice and other plantation crops.
While destroying Hawaii's diverse food system, the growers created a prosperous agricultural trading economy with mainland markets as customers. But competition from low-cost producers elsewhere has more recently devastated that economy. The last remaining sugar plantation closed in 2016.
The decline of the previously large sugar and pineapple industries now make Hawaii much more dependent on tourism as a source of income. Tourists are Hawaii's largest industry. They spent $15.6 billion in 2016 on vacations there representing about 18.5 percent of the total economy. That certainly underestimates their importance as many additional support services are needed to maintain the businesses that service the tourists.
