Mtwara, like the rest of Tanzania, is mostly a farming community. Farming is the main source of income for the region's residents. Agribusiness employs over 92 percent of the population, in addition to other rural activities such as fishing, beekeeping, and small-scale manufacturing. Arable land makes up about 85 percent of the region's total area. However, only about a quarter of this is cultivated. The average farm size per rural home (169,482 households - 1988 Census) is projected to be 1.5 ha, with an average of 4.4 people. Mechanization and oxenization of farms are still developing. In this area, the hand hoe is the most popular agricultural implement.
Cassava, millet, and sorghum are all important food crops, with maize only recently gaining popularity. The most important cash crop in the area is
cashew nuts, followed by groundnuts and sesame. Because livestock rearing is not a common practice among the people of the region, its economic contribution is negligible. The cashew nut crop, which accounts for about 25% of the region's GDP, is one of Mtwara's significant contributors. The Mtwara Region produces 40% of the country's cashew nut production. Tanzanian cashew nut production is mostly for export and predictably, only a small portion of the yield is consumed. The Mtwara Region is officially recognized as the country's leading cashew nut grower, producing roughly half of the country's output. Newala district produces more over half of the region's cashewnut harvest. Masasi comes in second with a 29 percent contribution, and Mtwara district comes in last with a 19 percent average contribution. The mining industry in the region has a bright future. On a limited scale, 35 minerals have been discovered and mined. The Masasi District has been mining
sapphire, christalbella, alexandrite, tourmaline, and rhodolite since 1995.
National Parks and Forest Reserves Mtwara Region is home to the
Mnazi Bay-Ruvuma Estuary Marine Park that is one of the largest marine parks in the country. The marine park is a sanctuary for breeding
Humpback whales. Forest reserves occupy about 8.33 percent of the region's 1,672,000 ha of land. This area is 139,295 hectares. Masasi district has the greatest amount of forest cover in the region. The central government manages 130,545 hectares of forest reserves. This equates to 93.7 percent. District councils possess another 8,749 hectares, or 6.3 percent of total forest reserves. In total, there are 16 forest reserves in the region. The majority of them are located in the Masasi district. ==Administrative divisions==
