The value of Burkina Faso's exports fell from $2.77 billion in 2011 to $754 million in 2012. Agriculture represents 32% of its gross domestic product and occupies 80% of the working population. It consists mostly of rearing livestock. Especially in the south and southwest, the people grow crops of sorghum, pearl millet, maize (corn), peanuts, rice and cotton, with surpluses to be sold. A large part of the economic activity of the country is funded by international aid, despite having gold ores in abundance.
