In a scenario of climate changes and increasing stress upon available fresh\nwater resources like rivers, lakes and aquifers, collecting fog water is a promising\nyet relatively unexplored potentiality. Providing sufficient water and reducing\nwater extractionââ?¬â?¢s environmental impact at the same time can be a\nchallenge with conventional ways, but fog harvesting technology presents itself\nas a powerful and efficient alternative. Water availability profoundly determined\nregional economic benefit, social relations and it also influenced environmental\nsecurity and ecosystem services. Underdeveloped countries have\nbeen dealing with water scarcity issue for decades, but also wealthy countries\nwill have to face the water crisis soon, due to unsustainable development\nprocesses. A review of the state of the art highlights the most relevant parameters\nto deal with when discussing about fog water harvesting. In regions\nwith frequent fog events, this technology already proved to be a sustainable\ndrinking water resource for rural communities and their low per capita water\nusage was provided by basic devices utilization. Nevertheless, in this paper,\ndifferent fog water harvesting applications are investigated, besides the already\nexisting fresh-water collection, reforestation and agricultural use. Further options,\nsuch as building components, outdoor activities and domestic devices\nare considered, according to different parameters, such as economic benefits,\npossibility of standardized production, life cycle and market attractiveness. A\ndesirable novel concept would become relevant in specific contexts, thanks to\nmultiple functions, offering locals designed and customized solutions. Also\nnoteworthy are the landscape impact of such devices and the effects of the\nproject in terms of places regeneration, raising awareness and ââ?¬Å?greenââ?¬Â conscience\ncreation. The study of local climatic data and improvement in fog collector\napplications, integration with architectural and landscape design, will\nexpand the regions where fog harvesting can be applied and its sustainable\nimprovements.
