(FILES) Workers load food commodities onto World Food Programme (WFP) SHERPs at the WFP logistics base in Bentiu, Unity State, South Sudan, on November 3, 2025. The SHERP all-terrain vehicles are used by the UN agency to deliver food and humanitarian aid to flood-affected and hard-to-reach areas. The amphibious vehicles have become vital for overland delivery as global aid cuts strain relief operations in South Sudan. Hundreds of thousands displaced by conflict in South Sudan are increasingly forced to sell part of their rations to pay for basic needs at a time when the economy has almost entirely collapsed. One of the world's poorest countries, South Sudan has been mired in corruption and civil war for much of its existence since gaining independence in 2011. When US President Donald Trump ordered the shutdown of USAID last year, South Sudan lost a huge chunk of its humanitarian support at a time when nearly two-thirds of the population -- some 7.9 million people -- face acute hunger.
