The Syrian crisis caused a massive influx of displaced people into neighboring countries, with Lebanon hosting the highest per capita number of refugees (3:10). Water remains the most critical natural resource that influences the resilience of host and refugee communities. We provide a new GIS-based updated water balance and water scarcity analysis at the national and the watershed level in Lebanon by comparing current conditions to no-refugee levels. Results show a small (6%) increase in water stress in an average water year at the national level that masks hot spots of water scarcity at the local geography. While domestic water use increased by 20%, we find that refugees’ water use is only 10% of agricultural water use in summer. We also show that interventions to rehabilitate the water networks can reduce water stress to better than pre-conflict levels (3% less stress).

难民，水的平衡和缺水：从黎巴嫩汲取的教训。

叙利亚危机导致大量流离失所者涌入邻国，黎巴嫩的人均难民人数最多（3:10）。水仍然是影响寄主和难民社区复原力的最关键的自然资源。通过将黎巴嫩目前的状况与非难民状况进行比较，我们提供了一个基于GIS的新的，经过更新的，在黎巴嫩国家和流域层面上的水平衡和缺水分析。结果表明，在全国平均水年中，水分胁迫的增加很小（6％），掩盖了当地地理上缺水的热点。虽然家庭用水增加了20％，但我们发现，夏季的难民用水仅占农业用水的10％。
