Some four million people in South Sudan are likely to face critical food shortages next month, British aid agencies have warned.
But the Disasters Emergency Committee says the cost of mounting an appeal to pay for aid might outweigh donations.
South Sudan’s president has already warned of “one of worst famines ever”.
More than a million people have fled their homes since fighting erupted between different factions of South Sudan’s ruling party last December.
Months of fighting in South Sudan has prevented farmers from planting or harvesting crops, causing food shortages nationwide.
Last month, South Sudan, which gained independence from Sudan in 2011, topped the list of fragile states in this year’s index released by The Fund for Peace, a leading US-based research institute.
