Agriculture makes up the majority (96%) of the region's economic activity, while 0.7% of the labor force is employed in the care of livestock. In the Katavi Region, small-scale farmers with dispersed land holdings for different crops are the main agricultural producers. Maize, rice, sunflower, sesame, groundnuts, cassava, millet, sweet potatoes, and sorghum are some of the major crop products produced. 2018 saw no ginneries in the area because farmers had only recently begun cultivating cotton.

Residents of the area also cultivate crops, but they also maintain sizable herds of native cattle, backed by a sizable grazing area that also draws pastoralists from neighboring areas. Less than 0.5 percent of the workforce is employed in the fishing industry. Forestry, mining, and tourism are some of the other significant industries in the area. Honey is produced in the Katavi Region and transported to other regions of the country, primarily Dar es Salaam, for processing and modern packaging.
