Beschreibung: <p>The collection of fog water is a simple and sustainable technology to obtain fresh water for afforestation, gardening, and as a drinking water source for human and animal consumption. In regions where fresh water is sparse and fog frequently occurs, it is feasible to set up a passive mesh system for fog water collection. The mesh is directly exposed to the atmosphere, and the foggy air is pushed through the mesh by the wind. Fog droplets are deposited on the mesh, combine to form larger droplets, and run down passing into a storage tank. Fog water collection rates vary dramatically from site to site but yearly averages from 3 to 10 1 m⁻² of mesh per day are typical of operational projects. The scope of this article is to review fog collection projects worldwide, to analyze factors of success, and to evaluate the prospects of this technology. this review is to synthesize the current understanding of fog collection and to analyze its potential and limitations for future development. In a sense, this is a follow-up contribution of a summary presented 20 years ago in Ambio (Schemenauer and Cereceda 1991). Note that the science of fog physics, chemistry, and its role in the hydrological cycle, which extends to a much wider climatic range than the "fog collection" addressed here, is not within the focus of this article.</p>
