In many parts of the world, droughts and an increasingly dry, arid climate have lead to water scarcity and in tandem, food scarcity too. 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.
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. To see more about the project, watch the video below.
“MY SURVIVAL FARM”
…and it’s like nothing you’ve ever seen before… An A to Z guide on survival gardening that is easy to read and a joy to put into practice, full of photos, diagrams and step by step advice. Even a kid can do this and, in fact, I encourage you to let the little ones handle it, to teach them not just about self-reliance but also about how Mother Nature works.
Here is just a glimpse of what you’ll find inside:
How to plan, design and put into action high-yield survival garden that will literally keep you and your family fed for life, no matter what hits you, even when everyone else around you is starving to death. No digging and planting year after year and no daily watering because you’ll have more important things to worry about when TSHTF.
How to set up highly nutritious soil for your plants. Do this before you plant anything and you’re on your way to setting your food forest on auto-pilot for decades to come. I’m gonna tell you this one “weird” thing to add to the mulch that’s not only highly effective but also 100% free (because you already have it in your home right now).
Step-by-step instructions on how to plant over 125 plants inside your permaculture garden. Plus, special instructions on choosing the right ones for your climate. From Arizona to Alaska, you can do this anywhere…
How to “marry” your plants. We’re gonna tell you which grow well together and help each-other survive and thrive, so they don’t ever compete for sunlight and nutrients. You get the full table of plants that work well with one another as well as the ones you should NEVER be put together.
