The South Region has a fair amount of industry, its main commerce consisting of logging, timber, mining, and offshore oil drilling. Commercial agriculture is also important in the South, the major cash crops being cocoa and rubber. Cattle rearing and fishing are significant economic components, as well. Much of the population is made up of subsistence farmers. In 2008, the President of the Republic of Cameroon, President Paul Biya signed decrees abolishing "Provinces" and replacing them with "Regions". Hence, all of the country's ten provinces are now known as Regions. The soil of the South is made up primarily of metamorphic rock, particularly gneiss. However, the land is riddled with faults around the border with the Centre Province that arc toward the border with Congo; granite deposits occur along this line. The soil is primarily ferrallitic except for southwestern portions near the border with Equatorial Guinea and moving north to Ebolowa, where it is mixed. Due to high amounts of leaching, the South's red earth is only marginally productive.
