Widespread flooding, caused by extreme rainfall and the release of excess water from a dam in neighboring Cameroon, has left 1.4 million Nigerians displaced and claimed 500 lives, according to government officials.

The floods also injured 1,546 people, completely destroyed 70,566 hectares of farmland and "totally damaged" 45,249 homes, said Nasir Sani-Gwarzo, Nigeria's permanent secretary of the Ministry of Humanitarian Affairs, Disaster Management and Social Development.

Floodwaters affected 27 of Nigeria's 36 states, officials said.

Satellite imagery from Landsat 9 showed major swelling of the Niger and Benue rivers in southern Nigeria, where NASA wrote floodwaters "inundated numerous communities." Where the rivers converged, the imagery revealed floodwaters overwhelming Lokoja, the capital of the state of Kogi.

"Flooding continued to the south, including a noticeably widespread area spanning southern Kogi and the northern part of Anambra state," NASA reported.

Last week, 76 people drowned in Anambra when their boat capsized as they tried to escape high floodwaters, according to multiple news organizations. Floodwater had risen as high as rooftops in Kogi and Anambra, CNN reported. Over 600,000 people have been displaced in Anambra due to floodwater.

"It's saddening. All of a sudden, people are left with no homes and turned to beggars in weeks. No matter how rich they were, the displacement has reduced them so much," Chiamaka Ibeanu, a registered nurse who lives in Onitsha in the state of Anambra, told The Washington Post.

Ibeanu's immediate family lives in Ossomari and Atani, nearby areas of Anambra close to the Niger River. She received word that her aunt and uncle had been displaced after their home was completely covered by water.

"The items she [her aunt] couldn't pack are in water . . . and she doesn't have any other home," Ibeanu said. "If not for the accommodation at the Primary Healthcare Centre, she would have been stranded."

Since the beginning of Nigeria's rainy season, which lasts from April to October, the Nigerian Meteorological Agency (NiMet) and the Nigerian Hydrological Services Agency (NIHSA), predicted flooding was imminent and that some parts of the country would witness increased rainfall paired with water from Lagdo Dam in Cameroon. They foresaw that the volume of water across Nigeria would increase.

"[C]ommunities must recognize that all disasters are local and they must take climate predictions and flood outlook warnings seriously," said Alhaji Ali Grema, Nigeria's director of humanitarian affairs.

Sani-Gwarzo said the scale of this year's flooding is similar to the last major flooding Nigeria experienced in 2012, which displaced 1.3 million people and claimed the lives of 431. In 2012, 30 of Nigeria's 36 states were affected.

"The scale of devastation can only be compared to the 2012 floods," said Sadiya Umar, the minister of humanitarian affairs, in a statement.

The submergence of farmlands has sparked fears of increased food insecurity and heightened food prices.

"Their farmlands are covered in the flood. This means that what was planted is swept away and there might be food scarcity next year," Ibeanu said.

The humanitarian affairs ministry said the federal government has committed to providing relief to all communities.

"We are taking all the necessary actions to bring relief to the people affected by the flood. All relevant agencies have renewed their commitment to strengthen their efforts in reaching out to the victims and bringing relief to them," Sani-Gwarzo said.

On Friday, the humanitarian affairs ministry announced that the Nigerian government had begun to distribute 12,000 metric tons of food and nonfood items to states devastated by the flooding.

Nigeria's national policy document on climate change, published in 2020, states floods have increased in recent years and that climate change is expected "to increase the frequency and intensity of severe weather events."

"Unfortunately, many States in Nigeria largely lack the infrastructure necessary to respond adequately to such events," the report states.
