Fog Harvesting: An Effective Solution to The Water Scarcity Problem

Abstract

Fog harvesting, also known as fog collection, is a sustainable approach to addressing water scarcity which captures water droplets from fog, providing a renewable water source for water-scarce regions. The aim of this study is to give more background about fog harvesting by introducing fog harvesting systems, their advantages and disadvantages, real world and laboratory projects and efficiency. This study emphasizes fog harvesting's potential in arid regions with frequent fog occurrence, discusses working mechanisms, and explores nature-inspired and nanotechnology-based fog collectors. Local climate data's importance for feasibility assessment is highlighted, along with the vital role of community involvement for long-term success. Fog harvesting offers a promising and environmentally friendly solution to alleviate water scarcity challenges when combined with innovative strategies and community engagement. Real-world projects have shown that fog water collection can be an effective and sustainable solution, particularly in regions with persistent fog and limited water resources. However, more work is needed on innovative fog collectors and advanced materials to increase sustainability.
