Increasing salinity remains a challenge to sustainability of irrigated agriculture in Ethiopia and South Sudan as it reduces natural biodiversity as well as farm and livestock productivity. Agriculture sector in Ethiopia supports 85 percent of the work force. About 85 percent of the population living in rural areas is directly dependent on agriculture for their livelihood. There are 7 million smallholder farmers, which produces more than 95 percent of the total agricultural outputs including food crops, cereals, oil seed and pulses.
