This paper discusses the probable impacts for children of different ages from the increasing risk of storms, flooding, landslides, heat waves, drought and water supply constraints that climate change is likely to bring to most urban centres in Africa, Asia and Latin America. It also explores the implications for adaptation, focusing on preparedness as well as responses to extreme events and to changes in weather patterns. As is the case with many poor groups, the report argues that adaptations to climate change that fail to take account of the disproportionate risks for children (who make up between a third and half of the population in the most affected areas) will be less than adequate in responding to the challenges.
