安全饮用水短缺是孟加拉国沿海地区的一个严重问题，主要是由盐碱入侵造成的。在这方面，饮用水源受到严重影响，包括对农业、卫生、渔业和生态系统的不利影响。本研究调查i）选定的水质参数ii）当地人对饮用水短缺的看法iii）当地人如何科普安全饮用水短缺。本研究采用当地水样，200户家庭的问卷调查和4个焦点小组讨论（FDG）在Shyamnagar和塔拉县Satkhira区进行。水质参数的研究揭示了该地区饮用水源的极端条件。总溶解固体（TDS）、电导率（EC）和氯离子浓度（Cl-）的平均值在Shyamnagar分别为4044.12 mg/L、7186.7 μ S/cm和3143.6 mg/L，在Tala分别为2313.60 mg/L、43903 μ S/cm和1402.1 mg/L。社区认知的结果表明，当地居民都意识到安全用水的短缺，几乎所有人都认为盐分是其背后的主要原因，尽管有一些社会经济因素，社区有自己的适应技术来科普这个问题。该研究最后以社区为基础的模式的发展，界定的主要责任的利益相关者，包括地方和中央政府，非政府组织和社区人民的工作，在一个良好的协调方式，这将是有效的减少安全饮用水的稀缺。(C)2016爱思唯尔有限公司版权所有
Safe drinking water scarcity is an acute problem in the coastal regions of Bangladesh which is mainly caused by salinity intrusion. In this context, drinking water sources are severely affected, including adverse effects on agriculture, health, fisheries and the ecosystem. This research investigates i) selected water quality parameters ii) local people's perception on drinking water scarcity iii) how local people's cope with safe drinking water scarcity. This research was conducted using local water samples, questionnaire survey of 200 households and 4 focus group discussions (FDGs) in Shyamnagar and Tala subdistrict of Satkhira district. The study of the water quality parameters exposed the extreme conditions of the drinking water sources in the area. The average values of total dissolved solids (TDS), electrical conductivity (EC) and Chloride concentration (Cl-) were found respectively 4044.12 mg/L, 7186.7 mu S/cm, and 3143.6 mg/L in Shyamnagar and 2313.60 mg/L, 43903 mu S/cm, and 1402.1 mg/L in Tala. The result of community perception reveals that local people are aware of the safe water scarcity and nearly all of them perceive that salinity is the main reason behind it. Even though there are a number of socioeconomic factors, communities have their own adaptation technologies to cope with the problem. The study concludes with the development of a community based model defining the key responsibilities of the stakeholders, including local and central government, NGOs and community people to work in a well coordinated manner which will be effective for reducing the scarcity of the safe drinking water.
