Hello, welcome to the programme.
This is News Hour from the BBC World Service.
We're coming to you live from London.
I'm Paul Henley.
New research has predicted that more than 14 million of the world's most vulnerable people,
a third of them children,
could die because of the Trump administration's dismantling of US foreign aid.
A study in the prestigious Lancet Journal is published as world and business leaders gather for a UN conference in Spain this week,
hoping to shore up the global aid sector.
The US Agency for International Development had provided over 40% of global humanitarian funding until Donald Trump returned to the White House in January.
Two weeks later, Trump's adviser and the world's richest man,
Elon Musk, boasted of having put the agency through the woodchipper.
The government said 83% of its programmes would be cancelled.
I've been speaking to one of the authors of this report in The Lancet, Davide Rasela.
We first analyzed the impact of USAID funding in the last two decades.
Based on this study, we projected the future.
Other studies conducted by independent groups with different data sets and different methodologies are coming more or less to the same magnitude of effect.
We are all discussing about millions of deaths caused by USAID funding in the next years.
Now USAID is a huge programme and it covers vastly diverse aid.
How can you put them all together and be sure of an overall figure?
