The region is economically the most active and industrialized in the state. It contains the major
Cerro de Oro and
Miguel Alemán dams, which play a central role in flood prevention in the
Papaloapan River basin in Veracruz, and are important sources of hydroelectric power. Industries include small-scale manufacture of fine wood furniture, sugar mills, chemical plants, refrigeration, fruit packers, paper mills, ethanol distillery and brewery. The region has deposits of oil, gold, uranium, coal and copper that have not yet been exploited. With fertile, well-watered soil, pineapple is the primary crop, as well as rice, mango, litchi, banana, sugarcane, watermelon, green pepper, snuff, lemon, rubber, malanga and orange. There are large areas of grassland used for grazing cattle, thoroughbred horses, pigs and poultry. These are affecting soil fertility. Fisheries catch sunfish, tilapia, and red tenhuayaca in the springs, dams and rivers. ==History==
