Abstract: (16 Views) |
| The mountainous regions of Eshkevar-e Rudsar, renowned as a major center for hazelnut cultivation and medicinal plant production in Iran, face persistent challenges in securing sufficient water for both agricultural and domestic purposes. In these highland areas, rain and fog serve as valuable sources of water, and local residents have developed various rainwater harvesting systems to make optimal use of environmental resources. This article explores the potential of fog water collection systems implemented in the mountainous village of Saravarsoo, Eshkevar-e Rudsar, which has an average relative humidity of 63.7%. Continuous monitoring of metal mesh fog collectors over 365 days recorded 69 foggy events in the area. On average, the total amount of water collected per m² was 500 L year⁻¹, with a mean daily yield of 7.37 L m⁻² day⁻¹. The highest monthly collection was observed in December (12.4 L m⁻² day⁻¹), while the lowest occurred in February (1.5 L m⁻² day⁻¹). Successful implementation of fog water harvesting projects depends on both technical and social factors, including fog frequency, wind speed and direction, fog moisture content, topography, community water needs, and local participation in the installation, monitoring, and maintenance processes. Given its low installation and maintenance costs, fog water harvesting, alongside rainwater collection methods, offers a sustainable and practical approach to addressing part of the water demand in vulnerable mountainous regions. |
