The book pays particular attention to the importance of power relations in influencing the extent to which children's voices are heard and acted upon by international development actors. The book weaves together theory, mixed method approaches and case studies spanning a number of policy sectors and diverse developing country contexts in Africa, Asia and Latin America. It therefore provides a useful introduction for students and development professionals who are new to debates on children, knowledge and development, whilst at the same time offering scholars in the field new methodological and empirical insights.
