Ensuring adequate and safe shelter for the refugees has been the core part of UNHCR's response in the Rohingya Refugee Crisis Operation from the beginning of influx. Moving forward from emergency shelter kits (ESK) distribution to upgrade shelter kits (USK) distribution, in 2019 UNHCR has initiated a need based targeted shelter repair and replacement assistance to maintain adequate shelter conditions. In line with this approach, condition of the shelters have been assessed in order to identify the individual shelter needs and specific needs of vulnerable families by the technical staff of shelter partners according to criteria and information have been collected through GIS tool. A total of 59,920 shelters were assessed. Based on the outcome of the assessment, most vulnerable shelters have been provided shelter support for Repair and Replacement and less vulnerable shelters are also receiving support for repair and replacement.
