Sharp Cuts in US and European Development Aid May Cause Over 22 Million Preventable Deaths by 2030, Study Warns

Abrupt reductions in development aid from major donor countries including the United States, United Kingdom, Germany, and France could lead to more than 22 million additional deaths worldwide by 2030, according to a landmark study released in November 2025. This includes an estimated 5.4 million deaths among children under five, threatening to reverse decades of global health progress in developing nations.

Key Findings:

A rigorous study led by the Barcelona Institute for Global Health (ISGlobal) analyzed data across 93 low- and middle-income countries to project the consequences of further cuts in official development assistance (ODA) scheduled for 2025. The research modeled scenarios ranging from mild to severe reductions in aid:

Severe aid cuts—up to 25% in the poorest countries and 28% in sub-Saharan Africa—could result in approximately 22.6 million additional deaths globally by 2030, including 5.4 million children under five.
A milder scenario with less drastic cuts still predicts 9.4 million preventable deaths, including 2.5 million children under five.
These projections surpass estimates from earlier studies focused solely on US aid reductions, which had predicted over 14 million excess deaths globally.

The study highlights that simultaneous cuts by multiple major donors would make it difficult for affected countries to adapt, risking large-scale setbacks in efforts to control infectious diseases, improve maternal and child health, and reduce poverty.

Expert Perspectives:

Dr. Caterina Monti, a lead researcher at ISGlobal, emphasized, “The loss of aid threatens to reverse three decades of unprecedented gains in health, education, and poverty reduction in developing nations.” She likened the impact to a shock comparable to a major global pandemic or conflict.

Independent global health experts not involved in the study echoed these warnings. Dr. Leonardo Martinez, assistant professor of epidemiology at Boston University School of Public Health, noted, “These funding cuts risk sharply increasing preventable deaths, particularly in the most vulnerable populations in low-income countries, undermining years of progress against diseases like tuberculosis and HIV.”

Context and Background:

For nearly three decades, sustained development aid from high-income countries has underpinned improvements in health infrastructure, disease control programs, maternal and child health initiatives, nutrition, education, and sanitation services in low- and middle-income nations. The US and several European countries have recently announced the first reductions in foreign aid budgets in decades, with Britain, France, the Netherlands, and Belgium cutting aid by 30-40%.

This shift follows the withdrawal of emergency COVID-19-related supplementary funding, combined with broader fiscal constraints and changing political priorities among donor countries.

Studies also document specific disease impacts: US aid cuts could result in over 10 million additional tuberculosis cases and 2.5 million TB deaths, especially affecting children and regions with high HIV-TB co-infection rates. Disruptions affect vaccination programs, HIV/AIDS treatments, malaria control, and other essential health services.

Implications for Public Health:

The projected death toll signals a potential reversal of global health gains and highlights the fragility of health systems heavily reliant on external funding. Vulnerable populations, especially children under five, could suffer disproportionately from vaccine-preventable diseases, malnutrition, and inadequate maternal care.

Health experts call for renewed international cooperation and urgent alternative funding mechanisms to sustain critical health programs. Without immediate and coordinated responses, progress towards Sustainable Development Goals (SDGs) related to health and poverty reduction risks significant derailment.

Limitations and Counterarguments:

While the study uses robust modeling, real-world outcomes depend on multiple factors, including possible policy changes, donor readjustments, and adaptive responses by recipient countries. Some argue that aid efficiency and domestic resource mobilization must improve to reduce dependency. However, experts caution that abrupt withdrawal of funding without transition strategies poses immediate threats to population health.

Practical Takeaways for Readers:

International aid plays a critical role in supporting health systems in developing countries.
Sharp reductions in aid can lead to increased preventable deaths and disease outbreaks globally.
The global interconnectedness of health means these effects may also indirectly influence wider regions, including high-income countries.
Public awareness and advocacy can influence policymakers to prioritize sustained global health funding.
