Under the scorching sun, away from their makeshift tent of thatch, bamboo, and a trampoline sheet used as roofing, Pwanabeshi Job* washes clothes with a three-month-old baby strapped to her back. Her two-year-old son plays nearby, while her eldest fans the burning coal to ensure lunch can be ready. Her husband was out.
Before resorting to life on the streets of Imburu, a community in Numan Local Government Area, Adamawa State, northeastern Nigeria, the family of five lived under a proper roof.
However, by early August, they, like many others in the Numan and Lamurde areas, grew anxious, knowing that from mid-August through September, their houses are usually flooded.
Each year, as the Benue River, one of West Africa’s largest rivers, swells, it pushes into homes and farms across Numan, where it meets with the Gongola River. The rising waters, which carved through the fertile Benue Valley, a region long prized for farming, leave communities across the area, such as Imburu, Hayin Gada, Ngbalang, Lure, and Opalo, quickly submerged.
Some residents migrate to neighbouring communities, while others, like Pwanabeshi, gather mats, chairs, cooking utensils, clothes, and other essentials to settle on the street. There, on higher ground beyond the reach of the floodwaters, they remain for about two months. For many, this has become a way of life since 2022.
Cycle of displacement
Locals told HumAngle that flooding was first recorded on a large scale in Adamawa in 2012, especially in the Benue Valley. For the next decade, no incident of that scale was recorded. But in 2022, another devastating flood displaced more than 130,000 people across 153 communities. Twenty-five lives were lost, and properties were severely damaged. Heavy rains, dam spillover, and river overflow were said to be the causes of the incident.
Flooding returned the following year. In 2023, unusually heavy seasonal rain combined with the occasional release of water from the Lagdo Dam in Cameroon led to floods that destroyed homes and infrastructure in Fufore, Demsa, Shelleng, and other local government areas.
By August 2024, communities such as Kwakwambe, Lure, and Imburu were again affected by a flood, this time linked to overflow from the Kiri Dam in Shelleng. In Madagali, floods struck due to the upstream flow of water from the Cameroonian highlands.
Most recently, in July 2025, a violent flood ravaged communities in Yola, the Adamawa State capital, claiming lives and properties. By August, communities around the Benue Valley began to migrate after water levels rose and flooded their homes.
A study identified the opening of dams, excessive rainfall, rising water levels, and poor drainage, among other factors, as the major drivers of floods in Adamawa State. It also noted that many residents fail to heed early flood warnings.
Lives under water
On the streets of Imburu, affected residents like Pwanabeshi make do with thatch shelters, each separate but stretched along a street so long that it takes about thirty minutes to walk from one end to the other. They sleep, cook, and carry out domestic chores. With no bathrooms and toilets, they bathe and relieve themselves in nearby bushes, usually before dawn or at night.
While every household is trying to continue their normal life on the streets, things are tough. The trampoline that covers Pwanabeshi’s shelter leaves gaps, so rain seeps in, soaking the mud floor and chilling the family. “The weather is cold, the mosquito nets we have are not enough, and we are many here, including children,” she said.
Others face similar struggles. Dati John, a mother of six, keeps a plastic container in the middle of her tent to catch dripping water when it rains.
“I’ve been staying here for over three weeks,” she told HumAngle.
Within this period, Dati said that her children have fallen ill several times, but she could only afford paracetamol until workers from the local primary healthcare centre distributed drugs on Sept. 14. “My basic concern is proper shelter and drugs for our children. If we can get those waterproof tents and mosquito nets, then it’ll go a long way for all of us here,” she said.
According to Dennis Sarka, the community leader of Hayin Gada, about thirty households have been flooded in his community so far. He is unsure of the total number of affected households in Imburu, but he says they are the most affected.
The hardship in these communities goes beyond shelter. The floodwaters have also wiped out the residents’ main source of livelihood—farmlands. Talegopwa John said he lost his entire farm, unable to estimate the hectares submerged or the worth of what was destroyed.
“Some people cultivated large hectares of maize and soya beans, but the flood destroyed everything,” he said. Although the residents were informed about the looming flood months ago, they did not have anywhere else to cultivate their farm, so they clung to hope.
“That is why I no longer cultivate rice or maize, because the rain washes them away easily. Now, I only farm millet, which can withstand the flood,” said Ramson Mandauna, a retired civil servant and full-term farmer who lives in Imburu.
The 69-year-old said he didn’t experience flooding as a child living in the community. But over the past four years, he has lost his farmland repeatedly and has been forced to live on the streets each rainy season.
“What we need now is food and how to bring an end to the flooding,” Talegopwa said.
For children and educators in Imburu, the crisis is not just about lost shelter or farmland; it is also about lost education. September marks the start of a new academic year, but pupils cannot attend classes because Kwakwambe Primary School, located in Hayin Gada within the Benue Valley, is submerged. Locals have nicknamed it the ‘Marine Academy’.
Each year since 2022, the school, which has a population of about 100 pupils, has been forced to close from mid-August through September, leaving children from Imburu, Hayin Gada, and neighbouring communities at home until the water recedes and classes resume in October.
Dennis told HumAngle that a non-governmental organisation recently surveyed the area with plans to build another school in a location that is not prone to flooding. “We have provided them with land, and we are expecting work to begin soon,” he said.
These days, some of the out-of-school children spend their days swimming in the flooded areas.
‘Dredge the Benue River’
Agoso Bamaiyi, an environmental scientist from Adamawa State, says the overflowing of the Benue River through its tributary, the Gongola, is the main driver of flooding in the region. While climate change and global warming contribute to the rising frequency and intensity of floods worldwide, he argues that the Benue’s overflooding remains the central cause in Adamawa.
“The release of huge volumes of water from the Lagdo Dam and the fact that the Benue trough is silted so much that it cannot hold the resultant runoff anymore a major reasons,” he stated, adding that the situation worsens each year.
Agoso believes the suffering can be significantly reduced if the Benue is dredged and a reservoir dam is constructed. He said the dam, which could be completed within four to five years, would store excess water released from Lagdo, provide irrigation and electricity, and release water back into the Benue at a natural flow. “If this is done, the flooding caused downstream would be averted,” he said, stressing that dredging would restore the depth and banks of the river, allowing it to carry more water away from farmlands and communities.
“This will also restore year-round navigability and the economic benefits thereof,” he added.
