World Food Program or WFP Country Director in South Sudan Matthew Hollingworth hopes guns go silent to give people a chance to re-build their livelihoods.
UNICEF Representative in South Sudan, Dr Mohamed Ag Ayoya says every child has the right to a healthy life.
He calls for efforts to ensure malnutrition needs are made.
The prevalence of acute malnutrition among children in South Sudan is estimated at 16 percent, above emergency.
It is also expected that 1.3 million children will suffer from acute malnutrition in 2020.
To tackle malnutrition, the UN agencies say all the underlying causes must be addressed, ranging from poor hygiene practices leading to diarrhoea, malaria and infant and young child feeding practices.
