GENEVA - A report published by the UN's Children Fund (UNICEF) on Tuesday found that some 530 million children live in areas with extremely high flood occurrence, while 160 million live in high drought severity zones.

Released ahead of the 21st United Nations climate change conference (COP21) in Paris, the report showed that 300 million of the 530 million children in flood prone zones live in countries where over 50 percent of the population live in poverty (surviving on less than 3.10 U.S. dollars a day).

The report said that out of the 160 million children living in drought-vulnerable areas, almost one third (50 million) reside in countries where over half of the population lives in poverty.

"The sheer numbers underline the urgency of acting now," UNICEF Executive Director Anthony Lake said in a statement.

"Today's children are the least responsible for climate change, but they, and their children, are the ones who will live with its consequences. And, as is so often the case, disadvantaged communities face the gravest threat," he added.

According to UNICEF, most of those living in high risk of flood areas are located in Asia, whereas the majority of the children living in areas at risk of drought are in Africa.

COP21, held from Nov. 30 to Dec. 11, will strive to unite world leaders into finding solutions to cut greenhouse gases. (Xinhua)
