Approximately 360,000 children, or 33% of those aged between 5 and 15, work in Liberia, primarily in agriculture. A significant number are engaged in the production of rubber on smallholder farms and large-scale plantations, often in dangerous conditions and at the expense of their education. According to the United States Department of Labour, major contributing factors to child labour in Liberia's rubber sector include household poverty, the existence of worker quota production systems, the high cost of adult labour, a lack of awareness, limited access to education, and limited inspection and enforcement of labour standards. The "Actions to Reduce Child Labor (ARCH)" project was implemented in Liberia from December 2012 to April 2017, The project targeted 10,100 children engaged in or at risk of entering exploitative child labour in Liberia, with a focus on the rubber sector. In addition, the project targeted 3,700 vulnerable households for sustainable livelihoods promotion. The project operated in the counties of Montserrado, Margibi, and Nimba. By the end of the project in March 2017, it had provided education services to 10,126 children and livelihood services to 3,700 households.
