Under the dappled light of a thatched shelter, Yagana Bulama cradles her surviving infant. The other twin is gone, a casualty of malnutrition and the international funding cuts that are snapping the lifeline for displaced communities in Nigeria’s insurgency-ravaged Borno state.

“Feeding is severely difficult,” said Bulama, 40, who was a farmer before Boko Haram militants swept through her village, forcing her to flee. She and about 400,000 other people at the humanitarian hub of Dikwa — virtually the entire population — rely on assistance. The military restricts their movements to a designated “safe zone,” which severely limits farming.

For years, the United States Agency for International Development had been the backbone of the humanitarian response in northeastern Nigeria, helping non-government organizations provide food, shelter and healthcare to millions of people. But this year, the Trump administration cut more than 90% of USAID’s foreign aid contracts and $60 billion in overall assistance around the world.
