Economy
Agriculture is the main economic activity as well as the number one source of livelihood of the people, although Dumalinao is a coastal town. The town is one of the major rice granaries of Zamboanga del Sur as 5,998 hectares of the land area is devoted to agricultural production. The crops planted on these lands include rice, corn, coconut, banana, and root crops. Corn, in particular, is the municipality's main agricultural crop. An estimated 2,837 hectares of the land are utilized for corn production, with an average of 30 ca-vans per hectare. On top of that, Dumalinao's climate is very conducive for growing corn, so much so that farmers usually get to have two croppings of corn per year. An estimated value of Php 51 million comes from the annual production of corn.
