"In the last decade of the 20th century, a new theme has emerged which will lead child-environment research into the 21st century: the identification and creation of environments consistent with the Convention on the Rights of the Child. This symposium analyses research trends that relate the principles of the Convention to Agenda 21 of the United Nations "Earth Summit" and the Habitat Agenda of the "City Summit," and discusses three case studies which successively apply Convention principles to the particular needs of early childhood, middle childhood and adolescence in urban communities."
