The task of bringing about change through participatory practices that promote personal and social protection of children is necessarily intergenerational. It requires changes in adult attitudes about children, risks and priorities. It requires collaboration between and within generational groups, to understand how progress towards social justice can be achieved. It also requires political challenge to dominant ideologies that lead to decision-making based on neo-liberal market principles rather than on evidence. Many of the children, young people and adults participating in the research and environments described in the articles within this volume are already engaged in trying to achieve these changes. We hope that this edition will provide readers with some inspiration for how further changes might be achieved.
