Bangladesh is experiencing one of the worst humanitarian crises in its history due to an unprecedented influx of refugees from Myanmar. In response to the crisis, the humanitarian community developed a Humanitarian Response Plan (HRP). The Government of Bangladesh (GoB) restricted the construction of semi-permanent and permanent structures in both refugee camps and makeshift camps. Poor shelter conditions have further exposed the Rohingya population to risks of floods, cyclones and landslides. Given that shelters had already been constructed but were far below standards in terms of living conditions and structural integrity, rather than using bamboo in the emergency kits the sector developed and promoted the shelter upgrade kit (USK), or phase 2. This kit consists of tarps, bamboo, fixings, tools and technical assistance with the aim of improving living conditions (with site improvements contributing to the effort) and shelter structural stability to better withstand climatic conditions. Together with several organisations, a joint-Emergency Market Mapping and Analysis (EMMA) was conducted to decide whether a market-based response was appropriate for the Shelter upgrade response.
