研究地区尼泊尔加德满都谷地，研究重点水资源短缺影响着全球40%以上的人口.低收入和中等收入国家的家庭通常使用替代自来水的水源，如地下水、罐装水和瓶装水，以及各种应对缺水的战略。本研究定量研究了使用多种水源和个人用水量之间的关系。此外，我们调查了2015年廓尔喀地震前后个人用水量与物理（即水源，供应时间）和非物理（财富状况，户主教育，房屋所有权，参与当地社区，水处理）因素之间的关系。对992户居民进行了三次社会人口统计、生活用水行为和社区参与的调查，并利用收集的数据进行了分析。使用地下水和罐装水的家庭尤其如此。此外，财富状况、户主受教育程度和房屋所有权与个人用水量增加有关，但这种联系在地震后不明显。除受地震影响的时期外，参与当地社区也与个人用水量增加有关。在所有调查期间，使用处理过的水的家庭消耗的水较少。
Study regionKathmandu Valley, Nepal.Study focusWater scarcity affects more than 40 % of the global population. Households in low- and middle-income countries typically use alternative water sources to piped water such as groundwater, tanker water and jar water and various coping strategies to deal with water scarcity. This study quantitatively examines the association between using multiple water sources and individual water consumption. In addition, we investigated the relationship between individual water consumption and physical (i.e. water source, supply time) and non-physical (wealth status, education for household head, house ownership, participation in local community, water treatment) factors before and after the 2015 Gorkha earthquake. A survey about socio-demographics, domestic water use behavior, and community involvement was conducted three times and the data collected from 992 households were used for analysis.New hydrological insights for the regionIt was confirmed that use of additional water sources is associated with greater individual water consumption. This was especially the case in households using both groundwater and tanker water. In addition, wealth status, education for household head, and house ownership were associated with increased individual water consumption but this association was not apparent after the earthquake. Participation in the local community was also associated with increased individual water consumption except for the period impacted by the earthquake. Households using treated water consumed less water across all periods surveyed.
