The handbook brings together contributions from academics and practitioners based in Armenia, Austria, Australia, Bulgaria, Cyprus, India, Finland, Germany the Netherlands, Denmark, Ireland, Italy, Lithuania, Portugal, Spain, Sweden, Switzerland, Turkey, the UK and the USA and covers the most pressing research areas relating to children and youth at risk, as well as the key theoretical perspectives and methodologies. The chapters examine areas such as poverty, crime, safeguarding, victimization, and young people's experiences of schools, communities or institutions, in combination providing a systemic understanding of risk ecologies. The contributors also explore how professional and institutional development for these groups of young people should be constituted. The book bridges gaps between research, practice and policy and is suitable for anyone working with, researching with, or developing strategies to support children and youth at risk.
