Water out of thin air: Harvesting Dew
In the Ethiopian highlands, it is common for farmers to not remove stones from their fields even though that makes it difficult for them to till the soil. In Yemen, entire valleys are blanketed with stones; trees are grown in gaps between them. Why? To harvest dew for water, which is then stored as soil moisture.
The latest post on TheWaterBlog (The Power of Dew) discusses these and several other practices from around the world, aimed at harvesting dew. The video OPUR, Conquest of the Dew claims that dew can be a crucial source of good-quality water in hot countries, citing successful results from Ukraine, France, India and Croatia.
Are there other stories of successes and failures in dew-collection that you know of? What’s the potential of upscaling/replicating them? Please share in the comments section below the blog post/video.
