ABSTRACT The Sundarbans, abutting the Bay of Bengal is home to about 7.2 million people; about 2.7 million in Bangladesh and the rest in India. Due to global warming the region is experiencing rise in sea surface temperature and sea level, increasing frequency of severe storms, and consequently, net land loss. What choices do communities and administrations have in the region? (i) Abandon and retreat, (ii) enhance resilience, or (iii) anticipate and facilitate transitions. This paper attempts to answer this question on the basis of a generic adaptation decision framework (GADF). The problem of climate vulnerability of the Indian Sundarbans is superimposed on the GADF to help administrations rationalize between choices. The threat of climate change-induced displacement in the ecoregion is real and the paper recommends a functional alliance between Bangladesh and India to bilaterally address environmental security issues, implying guarding against environmental degradation, and consequently, social disorder and conflict.

管理撤退：适应孟加拉三角洲孙德尔本斯生态区的气候变化

摘要 毗邻孟加拉湾的孙德尔本斯拥有约 720 万人口；孟加拉国约有 270 万，其余在印度。由于全球变暖，该地区正在经历海面温度和海平面上升，严重风暴的频率增加，从而导致土地净损失。该地区的社区和行政部门有哪些选择？(i) 放弃和撤退，(ii) 增强复原力，或 (iii) 预测并促进过渡。本文试图在通用适应决策框架（GADF）的基础上回答这个问题。印度孙德尔本斯的气候脆弱性问题叠加在 GADF 上，以帮助主管部门在选择之间进行合理化。
