Abstract

The lives and livelihoods of the people of Bangladesh are regularly threatened by natural disasters and climate dangers. Floods are the most common occurrence that puts people and their properties at risk. This study was conducted to assess the flood vulnerability of Chilmari upazila, which is located in Kurigram district of Bangladesh. Using a random sampling technique, primary data was obtained from 395 households in six unions of Chilmari upazila through a structured questionnaire survey. The Flood Vulnerability Index (FVI), an index-based approach, has been used to assess flood vulnerability. A set of 23 indicators has been fixed to assess four components of floods: physical, economic, social and environmental. Following this procedure, an FVI score was calculated for each of the unions (administrative unit of upazila) of Chilmari. Ashtamir Char, Nayerhat and Chilmari were designated as ‘very vulnerable’ based on the FVI study. Since these unions have relatively low levels of adjustability, coping ability and resilience, their sensitivity and vulnerability are high. Two of the unions of Chilamri are found to be highly vulnerable to floods and another to be generally vulnerable to floods. The results of the FVI analysis have been used to produce a flood vulnerability map of Chilmari upazila. As FVI consists of multi-dimensional indicators, the analysis can be used to pursue specific flood-mitigation measures in Chilmari.

利用指数方法了解洪水脆弱性:孟加拉国库里格拉姆Chilmari Upazila的研究
孟加拉国人民的生命和生计经常受到自然灾害和气候危险的威胁。洪水是最常见的灾害,使人们及其财产处于危险之中。本研究旨在评估位于孟加拉国Kurigram区的Chilmari upazila的洪水脆弱性。采用随机抽样的方法,通过结构化的问卷调查,对Chilmari地区6个工会的395户家庭进行了初步调查。洪水脆弱性指数(FVI)是一种基于指数的洪水脆弱性评估方法。已经确定了一套23个指标来评估洪水的四个组成部分:物理、经济、社会和环境。按照这一程序,计算了Chilmari的每个工会(upazila的行政单位)的FVI分数。根据FVI的研究,Ashtamir Char、Nayerhat和Chilmari被指定为“非常脆弱”。由于这些结合的可调节性、应对能力和恢复力相对较低,因此它们的敏感性和脆弱性较高。Chilamri的两个联盟被发现极易受到洪水的影响,另一个联盟则普遍容易受到洪水的影响。FVI分析的结果已被用于制作Chilmari upazila的洪水脆弱性地图。由于植被覆盖度由多维指标组成,该分析可用于寻求Chilmari的具体防洪措施。
