Extreme poverty, fast-growing populations, climate change, recurrent food and nutrition crises and insecurity are building up, threatening the lives of communities already living on the brink of crisis.
The regions most affected by Boko Haram - Logone et Chari, Mayo Sava and Mayo Tsanaga - have seen a 400 percent increase in the number of severely food insecure people, from 53,000 to over 200,000 in six months.
In 2016, some 23.5 million people – almost one in six - will not have enough to eat, of whom at least 6 million will require emergency food assistance. Acute malnutrition will threaten the lives of 5.9 million children under-five.
