Climate change and child wellbeing: a systematic evidence and gap map on impacts, mitigation, and adaptation

We developed a systematic evidence and gap map (2014-24) to assess how climate change impacts, mitigation, and adaptation affect the wellbeing of children aged 0-18 years globally, and discussed findings with the Children in All Policies 2030 Youth Advisory Board. Health was the most researched child wellbeing domain (84%; 948 of 1127 studies), followed by education (15%; n=171), and food security and nutrition (14%; n=160). Research on children's agency and resilience, displacement, socioeconomic distress, and safety received less attention. Health research gaps included limited studies on vector-borne diseases, children's mental health beyond post-traumatic stress disorder, and health outcomes for children aged 5-18 years. Mitigation and adaptation research focused largely on educational (45%; 114 of 252 studies) and behavioural changes (31%; n=79), with gaps in the evaluation of financing, infrastructure, technology, clean energy, and policy actions. Youth advisory board members emphasised the importance of schools, social media, and intergenerational dialogue in driving climate action while protecting children's wellbeing.
