In Chad, livestock herders are struggling to find grazing for their animals, and crops are not growing as they should due to worsening droughts and floods, according to Hindou Oumarou Ibrahim, a member of the African country’s Mbororo pastoralist community and winner of the 2019 Pritzker Award. As a result, people are being pushed deeper into poverty and are fighting over shrinking resources, she told a gathering on the sidelines of the U.N. climate conference in Madrid on Saturday, as the talks pushed into a day of overtime.

“The climate emergency is now,” she said. “We need our voices to be here… action must start now.”
