Many arid and semi-arid regions have very scarce drinking water resources, thus limiting their development potential. However, some of these regions do experience significant fog events or have daily ground-level dew, and if that moisture could be captured, collected, and stored safely and efficiently, this could be provide a valuable additional water resource. Kaseke and Wang [2018] catalog fog and dew research efforts around the world. They analyze an array of dew and fog collection approaches for drinking water, and in so doing provide valuable constraints on the resultant quantity, and more importantly the quality, of drinking water collected from these extraction schemes. Importantly, they note that most projects focus too narrowly on water quantity as a key outcome metric, and do not adequate examine the microbiological or geochemical parameters that address issues of drinking water safety. In a world where water distribution is already seriously impacted by climate change, more research and creative approaches to providing adequate, safe, and affordable water are sorely needed.
