Problem: Other legal factors that have been implemented to end and reduce child labour includes the global response that came into force in 1979 by the declaration of the International Year of the Child. Along with the Human Rights Committee of the United Nations, these two declarations worked on many levels to eliminate child labour. Although many actions have been taken to end this epidemic, child labour in Africa is still an issue today due to the unclear definition of adolescence and how much time is needed for children to engage in activities that are crucial for their development. Another issue that often comes into play is the link between what constitutes as child labour within the household due to the cultural acceptance of children helping run the family business. In the end, there is a consistent challenge for the national government to strengthen its grip politically on child labour, and to increase education and awareness on the issue of children working below the legal age limit. With children playing an important role in the African economy, child labour still plays an important role for many in the 20th century.
What is an issue in Africa with child labour definitions?
The answer is the following: unclear definition of adolescence
