Lake Chad Basin Crisis/Crise du bassin du lac Tchad

Since the formation of Boko Haram in 2002 and its subsequent insurgency into northern Nigeria, leading to the declaration of a state of emergency in the most affected states - Borno, Yobe and Adamawa - in 2013 and increased counter-attacks by a regional coalition force formed in 2015, the group has moved into neighbouring states, recruiting fighters and carrying out attacks. The result has been the displacement of 2.4 million people in the Lake Chad Basin region, which includes parts of Nigeria, Niger, Cameroon and Chad, to create one of the most severe and complex humanitarian emergencies in the world today, as the insecurity amplifies chronic drought, cholera and poverty endemic to the region.

However, delivering humanitarian assistance has been severely hindered by the volatile security situation and the remoteness of the region. Climate change and resource depletion as the lake’s water surface has shrunk from 25,000 square kilometres in the 1960s to only 2,500 square kilometres today, are compounding the crisis (DFID, 15 Mar 2017).

About 17 million people live in the affected areas, of whom 10.7 million need help. Most of the displaced families are sheltered by communities that are among the poorest and most vulnerable in the world. And with the lean season under way, food insecurity and malnutrition are reaching critical levels. In north-eastern Nigeria, some 5.2 million people are struggling with acute food shortages; in addition, 1.5 million people in Cameroon’s Far North region, 123,000 in Chad and 340,000 in Niger are also acutely food insecure (OCHA, 7 Jul 2017).

The UN is calling for $1.5 billion to address these issues and in February, at a conference in Oslo, 14 donor countries pledged $458 million to help the millions affected across the region this year. Another $214 million was announced for 2018 and beyond. In addition, the UN humanitarian chief, Stephen O’Brien, launched the Nigeria Humanitarian Fund to support emergency response in the northeast, in a bid to enable donors to pool contributions to deliver a more effective and timely response. However, as of July 2017, $1.04 billion in funding needs was still unmet (OCHA, 7 Jul 2017).

A la suite de l’apparition de Boko Haram en 2002 et de l’insurrection qui a suivi dans le nord-est du Nigéria, l’état d’urgence a été déclaré en 2013 dans les États les plus touchés de Borno, de Yobe et d’Adamawa. Après une contre-attaque accrue de la coalition armée régionale formée en 2015, le groupe s’est déplacé vers les États voisins, menant des attaques et recrutant des combattants. En conséquence quelque 2,3 millions de personnes ont été déplacées dans la région du Lac Tchad, qui recouvre plusieurs parties du Nigéria, du Niger, du Cameroun et au Tchad. Il s’agit d’une des plus sévères et des plus complexes crises humanitaires dans le monde aujourd’hui, alors que l’insécurité aggrave encore davantage la sécheresse chronique, le choléra, et la pauvreté endémique dans la région.

Par ailleurs la situation sécuritaire volatile et l’isolement de la région rend l’acheminement de l’aide humanitaire très difficile. Les changements climatiques et l’épuisement des ressources empirent la situation : l’étendue du lac Tchad est passée de 25,000 kilomètres carrés dans les années 60 à seulement 2,500 aujourd’hui (DFID, 15 mars 2017).

Quelque 17 millions de personnes habitent dans les zones touchées, et 10,7 millions d’entre elles ont besoin d’aide. La plupart des familles déplacées ont été accueillies par des communautés qui comptent parmi les plus vulnérables et les plus pauvres au monde. En pleine saison de soudure, l’insécurité alimentaire et la malnutrition atteignent des niveaux critiques. Dans le nord-est du Nigéria, quelque 5,2 millions de personnes font face à de graves manques de nourriture, auxquelles s’ajoutent 1,5 million de personnes dans la région de l’Extrême-Nord au Cameroun, 123 000 au Tchad et 340 000 au Niger qui se trouvent également en situation de crise alimentaire aigue.

L’ONU a lancé un appel de fonds de 1,5 milliard de dollars afin d’affronter cette situation, et lors de la conférence qui s’est tenue à Oslo en février 2017, 14 pays donateurs se sont engagés à verser 458 millions de dollars afin de venir en aide aux millions de personnes touchées par la crise cette année. Pour 2018 et au-delà, 214 millions supplémentaires ont été annoncés. Par ailleurs le chef de l’aide humanitaire à l’ONU, Stephen O’Brien, a lancé le Fonds humanitaire pour le Nigéria afin de soutenir la réponse d’urgence dans le nord-est, avec l’objectif de permettre aux donateurs de mettre leurs contributions en commun pour acheminer une aide rapide et efficace. Cependant, début juillet 2017 le manque de financement s’élevait encore à 1,04 milliard de dollars (OCHA, 7 juillet 2017).

Abuja, 20 September 2017 - The 34th session of the Expert Review Committee on Polio Eradication and Routine Immunization (ERC), cautions the Nigeria programme to guard against complacency as the country is ”not out of the woods yet”. The warning according to ERC, is germane, given recent antecedents despite one year without any reported case of wild poliovirus (WPV) in Nigeria.

In 2016, the Government reported four laboratory confirmed WPV cases between July and August after almost two years without the detection of WPV.
