The Kissi are primarily farmers. Rice, their staple crop, is grown on most hillsides and in low, swampy areas. Other crops include peanuts, cotton, corn, bananas, potatoes, and melons. Beans, tomatoes, onions, and peppers are grown in small vegetable gardens, and coffee is raised as a cash crop. Most of the farmers also raise some livestock.
Agricultural work, such as sowing, weeding, and harvesting, is shared equally by the men and women. Additional responsibilities for the men include hunting, fishing, and clearing land. The women's duties involve caring for the small vegetable gardens, tending to the chickens, trading in the local markets, and doing some fishing. Boys tend to the livestock, which are usually cattle and goats. Cows are considered very valuable animals, not for their milk, but as religious sacrifices.
