More than four hundred and twenty thousand children in the Amazon basin have been affected by dangerous levels of water scarcity and drought in three countries, according to the United Nations.

The record-breaking drought, ongoing since last year, is taking a toll on Indigenous and other communities in Brazil, Colombia and Peru reliant on boat connections, the United Nations Children’s Fund (UNICEF) said ahead of the COP29 climate change summit in Baku, Azerbaijan.

The UN agency has called on leaders to deliver critical actions, including a dramatic increase in climate financing for children.
