SOSUCAM, the largest sugar company in Cameroon, is a subsidiary of Somdiaa, a giant food and agribusiness company owned by the Vilgrain Group and the Castle Group, both of France. Under a 2006 contract with the Government of Cameroon, Sosucam received a long-term lease for 11,980 ha of land at the site of its 10,000-ha sugar-cane plantation in the Haute-Sanaga region. This land is added to a contract for 10,058 ha signed in 1965 to the original company SOSUCAM. Social rights groups have condemned the plantations and processing plants on numerous counts of human rights violations such as land dispossession, exposure to harmful chemicals, and loss of livelihood. According to CODEN only 4% of workers in the sugar plants are those who have lost their lands to the plantations. Sugar plants have been shut down twice in recent years due to worker protests but continue operations.
