Fog harvesting is real — and it’s bringing clean drinking water to communities in need.

High in the Anti-Atlas mountains of southwestern Morocco, there are several separated villages where the Berber individuals have actually lived for centuries.

As the descendants of the pre-Arab residents of North Africa, their history dates back to ancient timeshey have preserved their own language and culture despite many attempts to colonize them throughout history. Today, about 14 million Berber individuals live in Morocco. Over the past Thirty Years, life has actually ended up being progressively tough for the Berbers residing in the Anti-Atlas mountains because of desertification and abnormally intense droughts, consisting of one in 1986 that dried the region so much that it has never ever totally recovered.

Prior to, while it had constantly been warm and dry there, they had enough rainwater and well water to make it through and raise livestock. These long dry spells forced ladies and kids to spend an average of 4 hours a day on big salami to gather drinking water for their households and cattle. And throughout particularly dry summers, they had to trek even further.

When the water shortages got alarming, water had be taken by tanker truck, which was lengthy and pricey. They urgently required an option to their water problem, especially given that environment modification was most likely to make the task of discovering drinking water even harder.

Fortunately, their distinct climate offered them a potential option.

There is a large, stationary high-pressure system (called the Azores anticyclone) that flows air off the coast of Morocco over a cold-water current from the Canary Islands. This causes air to select up moisture and type clouds– specifically statocumulus clouds, which are low-lying and full of water. Wind then presses these clouds from the coast towards the Anti-Atlas mountains, but given that these mountains are high and chillier than the coast, they form a natural barrier– trapping the clouds and forming fog against the mountainsides.

Dar Si Hmad, a women-led NGO in Morocco, designed and installed a fog-water harvesting system– the largest in the world to this day– on the top of among these foggy mountains, Mount Boutmezguida.

The method fog-harvesting works is actually fairly simple: On the summit of Boutmezguida, high above the villages, finely meshed panels– or internet– were set up.

From those reservoirs, the water is piped directly to the towns and individual households. Up until now, this project in Morocco has actually supplied running water to 92 families, or nearly 400 individuals, the majority of them women and children.

The very best part? Fog water is pure, devoid of any impurities and toxins, so it can be used for drinking water without any treatment.

This makes fog-catching an exceptionally economical, efficient and eco-friendly method to harvest drinking water, and it can be used in other places where there are couple of or no viable methods to access water.

“Where there’s fog, we can harness it for the community, shop it when it’s required and use it later, instead of trying to find very costly and fossil-based solutions like desalinizing water, or digging more bore holes looking for even much deeper aquifers,” Dr. Jamila Bargach, director of Dar Si Hmad,told CNN.

The technique could be used in other parts of the world, also. FogQuest, a Canadian not-for-profit, has currently established fog-harvesting systems in South and Central America, the Middle East, and North Africa.

Where there is fog, this technology has the power to not only deliver clean water, but likewise to change individuals’s lives– particularly females and kids– all over the world. And the innovation will unquestionably become more vital in the future as droughts and environment change affect water materials globally.
