The current IPC analysis has counted 1.76 million people (18% of the Burundian population) in the humanitarian phase (IPC Phases 3 and 4). This reflects a slight improvement compared to the same period last year, with 3% of the population in Phase 4 in 2017, compared to 5% in 2016. The Imbo plain is the most affected and most vulnerable to food insecurity with 35% of the population in a food crisis and 4% in the emergency phase (IPC Phase 4) in 2017 B against 14% and 6% respectively in 2016B. The previous poor crop season left significant sequelae that even the good harvests of the 2017B season could not fully compensate, leading to a small increase in food security. The socio-economic crisis, which has become more pronounced since 2015, is increasingly affecting the livelihoods of households. Loss of economic opportunities, greater dependence on the market as prices continue to rise and erosion of purchasing power, make households' access to food ever more difficult.
