In September 2006, Tulane University initiated work on a U.S. Department of Labor (USDoL) contract to provide oversight of public and private initiatives to eliminate the WFCL and to assess progress made toward the implementation of the Harkin-Engel Protocol. In the following three years, Tulane University has carried out a pilot study and two nationally representative surveys of child labour in the cocoa sector in Côte d'Ivoire and Ghana and has implemented a range of smaller studies. These included a pilot study on child trafficking from Burkina Faso and Mali for labour on cocoa farms and an assessment of intervention activities in support of children in the cocoa-growing areas. In addition, Tulane staff has gathered information through discussions and information exchanges with key stakeholders involved in implementing the Harkin-Engel Protocol.
