A group of researchers in Northern Ethiopia are tackling the issue by creating a very low-tech solution that could have a huge impact. The Roots Up project, a non-profit organization affiliated with Ethiopia’s University of Gondar, has developed a dew collecting greenhouse that could help farmers grow fresh vegetables even in times of drought and also act as a source of clean drinking water. The simple design uses low-cost materials to both improve plant-growing conditions inside and act as a water harvester, making it an attainable technology for area farmers. The initiative wants to support highland farmers who've been facing low crop yields and food insecurity because of drought. © Roots Up The greenhouse traps hot air and humidity during the heat of the day, creating a better atmosphere for plant growth and then at night, a rope can be pulled that opens up a latch at the top of the greenhouse that lets cool air in, eventually reaching the dew point and creating condensation. The water droplets are channeled into a collection cistern and can be used for drinking water or for irrigation. In times of rain, the design can also be used as a rainwater collector. Roots Up plans to deploy these greenhouses in Northern Ethiopia soon and will offer training to local farmers on how to maximize their crop yields using the technology.
