This Operations Update n° 4 announces a revision in the Emergency Appeal, with a budget reduced to a total of CHF 851,786 (decreased from CHF 1m) to enable the IFRC to support the Niger Red Cross Society (NRCS) to deliver assistance to a total of 50,000 beneficiaries (decreased from 80,000), and extending the operation for an additional six months (to December 2015). This revision is largely due to the deterioration of the security situation in Diffa region and a resulting lack of access preventing the planned implementation resulting in some activities unachieved. This revision will enable the NRCS to address the initial and new unmet needs according to the current security situation in the new zone of intervention in Diffa and prioritizing the following sectors: health and care; water, sanitation, and hygiene promotion; food security, nutrition, and livelihoods; shelter and household items; and National Society capacity building. With CHF 372,742 available resources received, the net request is CHF 479,044.
