The humanitarian crisis in the six states of the North-Eastern Nigeria has intensified after eight years of violent conflict. In 2016, this was compounded as the Nigeria Government Forces took back territory previously held by the Boko Haram insurgency. The conflict caused widespread forced displacement, acute food and nutrition insecurity and serious human rights violations. Large areas of Borno State, the most affected, remained inaccessible to humanitarian assistance until early 2017 when only four of the most Northern Local Government Areas close to Niger remained as the only inaccessible areas. The security situation remains highly volatile even in the partially accessible Local Government Areas (LGAs) where periodic attacks occur, further threatening the lives and security of communities and humanitarian workers. The violence has also caused mass displacements to protected urban areas as well as neighbouring Lake Chad Basin countries. Due to the mass displacements, there is a high prevalence of food insecurity as communities that were largely dependent on agriculture for livelihood had their source of livelihood disrupted. There is therefore a high prevalence of severe malnourishment, morbidity and mortality. Displaced communities lack basic shelter, water, latrines and shower facilities leading to increased incidents and risks of communicable diseases. There is thus need for life saving support and activities to alleviate suffering through integrated and coordinated humanitarian response focussing on the most vulnerable people. There are approximately 4.2 million people in host communities and 1.5 million internally displaced persons (IDPs); 54% of the affected population are female and 59% are children. With disrupted agricultural production, poor functioning markets and high food prices, most of the population are dependent on humanitarian assistance with an estimated 3.3 million people food insecure (IPC phase 3-5) with numbers expected to significantly deteriorate during the lean season. The security situation and poor access continues to hamper humanitarian response forcing humanitarian actors to focus on Maiduguri, LGA Headquarters and some liberated zones.
