Unrelenting price rises and a brutal insurgency had already made it hard for Nigerians in northeastern Borno State to feed their families. When a dam collapsed in September, flooding the state capital and surrounding farmland, many people ran out of options.
Now they queue for handouts in camps for those displaced by fighting between extremist Boko Haram rebels and the military. When those run out, they seek work on local farms where they risk being killed or raped by local bandits, according to a Reuters report.
"I can't even cry anymore. I'm too tired," said Indo Usman, who tried to start again in the state capital Maiduguri, rearing animals for the two annual Muslim holy days, after years of repeatedly fleeing rebel attacks in rural Borno.
The flood washed that all away, driving her, her husband and their six children to a bare room at Gubio, an unfinished housing project about 96 km (60 miles) northwest of Maiduguri that has become a displacement camp.
Torrential rains and floods in 29 of Nigeria's 36 states this year have destroyed more than 1.5 million hectares of cropland, affecting more than nine million people, according to the Food and Agriculture Organization of the United Nations.
Climate change is a factor, as is Nigeria's poorly maintained or non-existent infrastructure as well as vulnerabilities caused by the weakening Naira currency and the scrapping of a government fuel subsidy.
The cost of staples like rice and beans has doubled, tripled or even quadrupled in a year, depending on location -- an unmanageable shock for millions of poor families.
Mass kidnappings for ransom in the northwest and conflict between farmers and pastoralists in the central belt, traditionally the nation's bread basket, have also disrupted agriculture and squeezed food supplies.
'HUNGRIEST OF THE HUNGRY'
Roughly 40 per cent of Nigeria's more than 200 million people live below the international poverty line of $2.15 per person per day, the World Bank estimates.
Already, 25 million people live in acute food and nutrition insecurity - putting their lives or livelihoods in immediate danger, according to a joint analysis by the government and UN agencies. That number is expected to rise to 33 million by next June-August.
"The food crisis in Nigeria is immense because what we are seeing is a crisis within a crisis within a crisis," said Trust Mlambo, head of programme for the northeast at the World Food Programme, in an interview with Reuters in Maiduguri.
With international donors focused on emergencies in Gaza, Ukraine and Sudan, Mlambo said there was not enough funding to fully meet Nigeria's growing need for food aid.
"We are really prioritising the hungriest of the hungry," he said.
In Borno, the Alau dam, upriver from Maiduguri, gave way on Sept. 9, four days after state officials had told the public it was secure. Local residents and engineers had been warning that it was under strain.
Hundreds of people were killed in the resulting flood, according to aid workers who did not wish to be identified for fear of offending the state government. A spokesperson for the state government did not respond to requests for comment.
Zainab Abubakar, a self-employed tailor in the city who lived in relative comfort with her husband and six children in a house with a refrigerator, was awoken at midnight by water rushing into her bedroom.
They ran for their lives while the flood destroyed their house and carried everything away, including her sewing machine. Now, they are sheltering at Gubio and collecting rice from aid agencies in a plastic bucket.
"There is no alternative," she said.
In Banki, on Nigeria's border with Cameroon about 133 km (83 miles) southeast of Maiduguri, Mariam Hassan lost crops of maize, pepper and then okra in repeated flooding of her subsistence farm this year, leaving her with nothing to eat or sell.
"I beg the neighbours or relatives to give me food, not even for me but for my children, for us to survive," said Hassan, who has eight children. "The situation has turned me into a beggar."
