New shelter design for displaced people being tested in South SudanListen /
Keeping displaced people comfortable, safe and healthy in temporary camps is one of the key challenges facing humanitarian agencies in South Sudan.
Over 850,000 people have been displaced in the country since December following an outbreak of hostilities between the government and rebels.
Extreme weather including high winds and rain leading to flooding has tested to the limit the temporary shelters that people have been living in.
The International Office for Migration (IOM) is working on modifications to shelters to make them more robust.
Lwak Nelson has been speaking to Mathew Graydon of the IOM about the shelters.
