Ethiopia sets up dew-collecting greenhouse to tackle water and food shortages

In many parts of the world, drought and an increasingly dry climate are leading to water shortages and, subsequently, food shortages. A team of researchers in northern Ethiopia is addressing this problem by creating a very Low-tech solutions This could have a huge impact.
this Rooted The project, a nonprofit affiliated with the University of Gondar in Ethiopia, has developed a dew-harvesting greenhouse that can help farmers grow fresh vegetables even during droughts while also serving as a source of clean drinking water.
The simple design uses low-cost materials and both improves growing conditions for indoor plants and acts as a water collector, making it an attainable technology for local farmers. The initiative aims to support upland farmers facing low crop yields and food insecurity due to drought.
The greenhouse captures hot air and moisture during the day’s heat, creating a better environment for plants to grow, then at night, a rope is pulled, unlatching the door at the top of the greenhouse, allowing cool air to enter, eventually reaching dew point and forming condensation. The water droplets are directed into a collection gutter, which can be used for drinking water or irrigation.
The design also acts as a rainwater collector when it rains.
