The economy of Honduras is based mostly on agriculture, which accounts for 14% of its gross domestic product (GDP) in 2013. The country's leading export is coffee (US$340 million), which accounted for 22% of the total Honduran export revenues. Bananas, formerly the country's second-largest export until being virtually wiped out by 1998's Hurricane Mitch, recovered in 2000 to 57% of pre-Mitch levels. Cultivated shrimp is another important export sector. Since the late 1970s, towns in the north began industrial production through maquiladoras, especially in San Pedro Sula and Puerto Cortés.
