He said that there has been a five and half percent increase in population in South Sudan which puts a lot of pressure on a new country.
The level of food insecurity in South Sudan cuts across the whole country however in relative terms the only state that produces a lot that what it need is Western Equatoria.
The most food insecure states are Unity, Warrap, Upper Nile, Eastern Equatoria, Northern Bahr el Ghazal and parts of Jonglei State.
Nikoi added that the number of Sudanese Refugees in South Sudan has also quadrupled, the country currently have about 170,000 Sudanese in Upper Nile and Unity states and this huge number of people adds pressure on food supply, food markets and on environmental resources.
He said that all these are the different elements that have made 2012 a particularly challenging food security year for South Sudan.
Food insecurity has led to an increase in malnutrition to more than 15 per cent on children under five in the six states.
