Water is indispensable for human survival. Freshwater scarcity and unsustainable water are the main growing concerns in the world. It is estimated that about 800 million people worldwide do not have basic access to drinking water and about 2.2 billion people do not have access to safe water supply. Southeast Asia is most likely to experience water scarcity and water demand as a result of climate change. Climate change and the increasing water demand that eventually contribute to water scarcity are focused upon here. For Southeast Asia to adapt to the adverse consequences of global climate change and the growing concern of environmental water demand, fog water harvesting is considered as the most promising method to overcome water scarcity or drought. Fog water collection technique is a passive, low maintenance, and sustainable option that can supply fresh drinking water to communities where fog is a common phenomenon. Fog water harvesting system involves the use of mesh nets to collect water as fog passes through them. Only minimal cost is required for the operation and maintenance. In conclusion, fog water harvesting seems to be a promising method that can be implemented to overcome water scarcity and water demand in Southeast Asia.
水对人类生存不可或缺。淡水稀缺和水资源不可持续是全球日益令人担忧的主要问题。据估计，全球约有8亿人无法基本获取饮用水，约22亿人无法获得安全的供水。东南亚很可能因气候变化而面临水资源短缺和用水需求问题。本文重点关注气候变化以及最终导致水资源短缺的不断增长的用水需求。为使东南亚适应全球气候变化的不利影响以及对环境用水需求的日益关注，雾水收集被视为克服水资源短缺或干旱的最具前景的方法。雾水收集技术是一种被动、低维护且可持续的选择，可为雾常见地区的社区提供新鲜饮用水。雾水收集系统利用网眼网在雾穿过时收集水分。运营和维护只需极少成本。总之，雾水收集似乎是一种有前景的方法，可用于克服东南亚的水资源短缺和用水需求问题。
