President Donald Trump's shuttering of USAID last year will have a long-term negative impact on children throughout the world, according to a report released on Thursday by Oxfam.

In its analysis, Oxfam estimates that a child under the age of five could die every 40 seconds by 2030 thanks to the Trump administration's dismantling of American foreign aid programs.

Oxfam says it's basing its projections on "calculations in [the] Lancet’s impact evaluation and forecasting analysis from last July, which projected "4,537,157 child deaths by 2030."

The report also pointed to estimates from the Institute for Health Metrics and Evaluation (IHME) and Gates Foundation, which calculates "an additional 200,000 child deaths" for children under five last year. This lines up with data published by the Boston University School of Public Health last year estimating over 250,000 child deaths caused by the drastic slashing of foreign aid funding under the Trump administration.

Abby Maxman, president and CEO of Oxfam America, said that "we have run out of words to describe the depths of suffering" caused by Trump's destruction of "the entire global aid system."

"We are seeing years of progress unravel, and more children suffer and die preventable deaths because of these cuts," Maxman added.

The report also highlighted the specific impacts cuts have had in Sudan, the Philippines, and Syria.

Mayfourth Luneta, deputy executive director of the Center for Disaster Preparedness Foundation, an Oxfam partner in the Philippines, said that due to the Trump aid cuts, her organization had to cancel programs across eight communities that were impacted by floods and earthquakes last year.

"The Philippines was hit with the most powerful storms on Earth recorded last year," Luneta said. "Communities were devastated, families were left with nothing."

Shabnam Baloch, country director for Oxfam in South Sudan, described the impact that aid cuts have had on a country that is undergoing a horrific civil war.

"Water borne illnesses are spreading rapidly, starvation is imminent for many, and while needs are rising, lifesaving organizations are working with a fraction of the resources we had in previous years," said Baloch. "Oxfam, along with many other vital organizations, will be forced to scale down our programs without immediate intervention."

Sara Savva, deputy director-general the alliance of the Greek Orthodox Patriarchate of Antioch and All the East and the Department of Ecumenical Relations and Development (GOPA-DERD), an Oxfam partner in Syria, said her organization had "to drastically reduce the scale and scope of our programs for Syrian families and Iraqi refugees residing in Syria" in the wake of the Trump administration's cuts.

"We were notified we will no longer receive funding from the US government, and thousands of people are left without crucial services necessary to rebuild their lives after a catastrophic civil war," Savva said.
