Since the escalation of violence in March 2015, when conflict broke out between forces loyal to President Abdrabbuh Mansour Hadi and those allied to the Houthi rebel movement, Yemen, already the poorest in the region, has been left on the verge of a humanitarian collapse.

Over the past few years, it’s the voice of Humanitarian Coordinator Jamie McGoldrick, that has been drawing the world’s attention the most loudly, and the most often, to Yemen’s plight.

He had extensive experience as a senior manager with the UN humanitarian affairs office (OCHA), before arriving in Yemen, in December 2015, and for our latest UN News interview podcast, he explains why he’s just stepped down from the job, and what it has been like to oversee one of the most difficult and challenging aid operations in the world.

McGoldrick tells UN News that to deliver aid to an increasingly desperate population in Yemen, there’s “no point in getting angry, there’s no point in getting frustrated, the point is to get smart.”
