西南沿海地区是喜马拉雅河三角洲的一部分，受到孙德尔本斯红树林的保护，不受潮汐的影响。这一地区是各种灾害的中心，如旋风、潮汐、洪水、干旱、盐碱入侵、反复内涝和地面沉降。气旋性潮涌和洪水是较常见的灾害，其影响经常发生在地方一级。但是，盐度增加、砷污染和干旱等无声和无形的灾害影响着该地区的当地生计、人民和环境。西南地区的脆弱性增加的盐度，砷污染和干旱是一个复杂的相互关系的结果，生物物理，社会，经济和技术特征的国家。此外，在当前和可预见的未来，该国可能会受到最大、最持久、全球规模但无声的灾难的影响：盐度增加、天然砷污染和干旱。因此，该地区被认为是孟加拉国最容易发生自然灾害的地区，而且极易受到气候变化的影响。
The southwest coastal region is part of an inactive delta of large Himalayan rivers and is protected from tidal surge by the Sundarbans mangrove forest. This area is the hub of all types of disasters such as cyclones, tidal surges, floods, drought, salinity intrusions, repeated waterlogging, and land subsidence. Cyclonic tidal surges and floods are the more common disasters, and their effects are frequently experienced at the local level. But silent and invisible disasters such as increased salinity, arsenic contamination, and drought affect local livelihoods, people, and environments in this region. The vulnerability of southwest region to increased salinity, arsenic contamination, and drought are the result of a complex interrelationship among biophysical, social, economical, and technological characteristics of the country. Moreover, in the current and foreseeable future, the country is likely to be affected by the biggest, most long-lasting, and global scale but silent disaster: increased salinity, natural arsenic contamination, and drought. Therefore, this region is thought to be the most disaster-prone region in Bangladesh because of natural disasters and highly vulnerable to the effects of climate change.
