Conflict and seasonal hazards make logistics a complicated undertaking in South Sudan, with more than 600,000 square kilometres of land area and one of the least-developed road networks in the world. In addition, more than 60 per cent of the country is cut-off from road travel during the rainy season, and violence-related access constraints often hinder logistics activities.

To help relief agencies deliver in this context, IOM supports logistics operations across South Sudan through the Common-Transport Service (CTS). The CTS is a free-for-user service that transports humanitarian supplies to key operational areas and field locations to help partners provide assistance to vulnerable populations.

IOM also manages mobile storage units across the country to store and pre-position relief supplies in areas cut-off during the rainy season.
