According to the Cadre Harmonisé, about 4.1 million people across Borno, Adamawa, and Yobe (BAY) states, in the north-east, risk facing acute food shortages during the upcoming lean season, from June to August. The Cadre Harmonisé is a standardized methodology for assessing acute food and nutrition insecurity in the Sahel and West Africa. The report indicates that about 587,000 people are in the emergency phase (phase 3) of the IPC Acute Food Insecurity classification. To avert catastrophic food shortages and a nutrition crisis, UNOCHA, WFP, FAO, UNICEF, the UK Foreign, Commonwealth Development Office (FCDO), and lead government agencies appealed for an urgent US $351 million on 8 April to rapidly scale up food and nutrition assistance ahead of the lean season, when the risk of flooding and disease outbreaks increases.
