Fog: a sustainable source of water for people, forests and afforestation
- Resumen
- Fog is a natural part of the hydrologic cycle and, like precipitation, provides a vital water source for all life. Its contribution to water inputs at a particular location can vary from 0 % to nearly 100 % in some high-elevation desert environments. Fog is composed of tiny, water droplets from 1 to 40 μm in diameter. Typical droplet diameters are around 10 μm. Some types of trees are efficient at collecting these small, wind-blown fog droplets. They coalesce on the needles or leaves to form larger drops and then drip onto the ground. In high-elevation forested areas, in temperate latitudes, this process can provide 20 to 50 % of the water input to an ecosystem. FogQuest, a registered charity, uses specially chosen meshes to collect fog water in arid environments, to provide water to communities, for domestic, agricultural and forestry uses. The background to fog collection and some current applications will be presented in this paper.
