Agriculture, livestock, forestry and fishing employ over 53% of the state's population; however, its productivity is considered to be low. Agriculture includes both seasonal and perennial plants. Major crops include corn, beans, sorghum, soybeans, peanuts, sesame seeds, coffee, cacao, sugar cane, mangos, bananas, and palm oil. These crops take up 95% of the cultivated land in the state and 90% of the agricultural production. Only four percent of fields are irrigated with the rest dependent on rainfall either seasonally or year round. Chiapas ranks second among the Mexican states in the production of cacao, the product used to make chocolate, and is responsible for about 60 percent of Mexico's total coffee output. The production of bananas, cacao and corn make Chiapas Mexico's second largest agricultural producer overall.
