The northeastern part of Bangladesh is characterized by a unique wetland ecosystem called haor, which experiences regular monsoon flooding starting from late May/June. But change in rainfall pattern over last few decades has resulted in increased risk of early monsoon flash floods like the flood of 2017, which wreaked havoc in the haor at the beginning of April. Through a cross sectional survey covering 1845 flood affected households, the present study aims at understanding this flood's effects on their livelihoods and recommending policies to safeguard livelihoods in the face of changing climate. Analysis of rainfall and river water level data revealed that heavy rainfall in the haor and adjacent Indian sub-catchments were the main reasons behind this unprecedented event. Loss of income because of this flood was common, but was more prevalent among the older respondents, people having lower educational attainment and persons dependent on natural resources-based occupations. Most of the people who were forced to switch occupations experienced reduction in average daily income, irrespective of whatever occupations they switched to. Food insecurity was common among all groups, but was predominant among fishermen and day labourers. Integrated measures including development of real-time early warning system, community-based early response, proper management of crop protection embankments and regular dredging of waterways are essential to reduce the vulnerability of the people to flood. Furthermore, rapid expansion of newly developed short duration rice varieties (e.g. BRRI dhan 81), employment of case seedlings/raised-bed seedlings in elevated lands to ensure high quality timely transplantation immediately after recession of stagnant water, introduction of other profitable crops, poultry and dairy farming (e.g. sheep farming), creation of skill-based alternative livelihood options to adapt the agriculture sector with the changing climate. An equitable investment by the government is crucial to foster the economic growth by ending poverty by 2030, and to secure decent income, better livelihood and food security of the haor inhabitants.

孟加拉国东北部有一个独特的湿地生态系统，称为haor，从5月下旬/ 6月开始定期发生季风性洪水。但在超过过去几十年降雨模式的改变导致了年初季风山洪像2017年洪水，这肆虐的风险增加haor在四月初。通过对涵盖1845个受洪水影响的家庭进行的横断面调查，本研究旨在了解这场洪水对其生计的影响，并提出应对气候变化的措施，以维护生计。降雨和河流水位数据的分析显示，强降雨在haor以及邻近的印度子流域是这一史无前例的事件背后的主要原因。由于洪灾造成的收入损失很普遍，但在年长的受访者，受教育程度较低的人以及依赖自然资源为基础的职业的人中更为普遍。不论他们从事何种职业，大多数被迫转行的人的平均日收入都有所减少。粮食不安全在所有群体中都很普遍，但在渔民和临时工中普遍存在。采取综合措施，包括开发实时预警系统，基于社区的早期响应，对作物保护路堤进行适当管理以及定期疏of水道，对于减少人们遭受洪灾的脆弱性至关重要。此外，新开发的短期水稻品种（例如BRRI dhan 81）的快速扩张，在高地上使用案例苗/高架床苗，以确保在停滞水退后立即高质量及时移植，引入其他有利可图的作物，家禽和奶制品农业（例如养羊），创造基于技能的替代生计方案，以适应气候变化的农业部门。政府的公平投资对于到2030年消除贫困，促进经济增长，确保非洲人获得体面的收入，更好的生计和粮食安全至关重要。引进其他有利可图的农作物，家禽和奶业（例如绵羊养殖），创造基于技能的替代生计选择，以适应气候变化的农业部门。政府的公平投资对于到2030年消除贫困，促进经济增长，确保非洲人获得体面的收入，更好的生计和粮食安全至关重要。引进其他有利可图的农作物，家禽和奶业（例如绵羊养殖），创造基于技能的替代生计选择，以适应气候变化的农业部门。政府的公平投资对于到2030年消除贫困，促进经济增长，确保非洲人获得体面的收入，更好的生计和粮食安全至关重要。haor居民。
