Sundarban Biosphere Reserve (SBR), an ecologically sensitive and dynamic region, is susceptible to cyclones, floods, storm surge and sea level rise. Multi-hazard events in the Reserve have severely affected the coastal landscape and increased the magnitude of various losses to the communities during the last ten years. Losses such as damage to houses, asset loss, land loss and livestock deaths have largely occurred due to multi-hazard events. This article makes an attempt to assess socio-economic losses occurred due to multi-hazards. We collected data regarding socio-economic losses from 570 sampled households through field survey using questionnaire. Poisson regression was performed to ascertain the relationship between losses and multi-hazard events. Pearson correlation was also utilized to examine the relationship between losses and government relief provided to the sampled households. Results revealed that of the 19 blocks (administrative divisions of the district), Namkhana and Sagar were found to be the most vulnerable blocks to the multi-hazard as maximum losses of house, livestock, land and asset of the sampled households occurred in these blocks. Patharpratima also suffered all types of losses except asset loss. Kultali and Basanti suffered from asset loss while Gosaba and Hingalganj suffered from livestock losses. Weak housing structure, lack of early warning system, insufficient relief, lack of basic amenities, coastal erosion and vicinity to the coast were the main factors for persistent vulnerability to losses in these blocks. Thus, these blocks accord high priority for lessening multi-hazards vulnerability.

Sundarban生物圈保护区（SBR）是一个生态敏感且充满活力的地区，容易受到旋风，洪水，风暴潮和海平面上升的影响。在过去十年中，保护区的多灾种事件严重影响了沿海景观，并增加了对社区的各种损失。由于多灾种事件，房屋损失，资产损失，土地损失和牲畜死亡等损失在很大程度上已经发生。本文试图评估由于多种危害而造成的社会经济损失。我们通过使用问卷的实地调查收集了570个抽样家庭的社会经济损失数据。进行泊松回归以确定损失与多灾事件之间的关系。皮尔逊相关性还用于检验损失与提供给抽样家庭的政府救济之间的关系。结果显示，在这19个街区（该地区的行政区划）中，Namkhana和Sagar被发现是最容易受到多重危害的街区，因为这些街区的房屋，牲畜，土地和资产的最大损失发生在这些街区。除财产损失外，Patharpratima还遭受所有类型的损失。Kultali和Basanti遭受资产损失，而Gosaba和Hingalganj遭受牲畜损失。住房结构薄弱，缺乏预警系统，救济不足，缺乏基本便利设施，沿海侵蚀和沿海附近地区是造成这些区块持续遭受损失的主要因素。从而，
