As towns dry out and the desert advances, women in Morocco climb the mountains to capture the fog and turn it into drinking water

A chance experiment took place in the 1980s. Some researchers working in the Atacama Desert accidentally left a simple metal mesh exposed to wind at night. The next morning they discovered that it was covered in water droplets in one of the driest places on the planet. That seemingly trivial scene ended up inspiring an idea that decades later would change the lives of entire towns.

Capture the fog before it disappears. As the desert slowly advances over southwestern Morocco and traditional wells begin to dry up, several villages in the Aït Baâmrane region have found a solution which seems closer to a science fiction image than to conventional hydraulic infrastructure: capture the fog from the mountains and convert it into drinking water.

For generations, the women of these communities spent up to four hours a day walking to remote wells and returning carrying barrels weighing almost 25 kilos on their heads. That routine organized the entire life of the villages, kept many girls out of school and reflected the extent to which the lack of water conditioned any daily activity on the edge of the Sahara.

Giant nets convert air into water. The change began when huge polymer networks They appeared on the slopes of Mount Boutmezguida, at more than 1,200 meters above sea level. The idea is surprisingly simple: take advantage of the moisture from the Atlantic fog that regularly passes through the Anti-Atlas mountain range. The tiny droplets become trapped in the mesh, condense and end up descending towards deposits connected to kilometers of pipelines by gravity.

Without complex pumps or large industrial infrastructure, the system manages to carry water directly to homes using only wind, altitude and ambient humidity. Thanks to the advances in materials engineeringthese modern networks are much more efficient than the experiments carried out decades ago in countries like Chile, Yemen or Eritrea.

And the fog reached the tap. When the system went live, neighbors gathered to see something they had never seen before: water coming directly from a faucet inside a home. That “fog water”as they began to call it, quickly transformed the daily life of the villages. Women stopped spending part-time carrying water and many girls were able to attend school regularly again.

The project, promoted by the NGO Dar Si Hmadnot only modified water management, but also the social balance of communities where transporting water had been an exclusively female responsibility for centuries.

The cultural challenge of drinking water that did not touch the ground. The technology worked from the beginning, but convincing everyone was much more difficult. Some inhabitants they distrusted of a water that had never passed through the earth and that, as they believed, lacked minerals and “life”. The fog represented something ambiguous, almost unreal, too far from traditional sources.

Over time, the rejection disappeared as the families verified that the water was safe and constant. The transition also forced us to work unexpected social issues: Some women felt that they were losing part of their central role in the home by no longer being in charge of fetching water. That is why the project ended up incorporating literacy, technical training and community management along with hydraulic infrastructure.

Finding water is impossible. The UN has recognized this May 2026 that the Moroccan system is one of the more interesting examples of climate adaptation against desertification. The project shows that some extremely dry regions can still take advantage of invisible resources which until now were hardly used.

However, it also makes clear that does not exist a universal solution: capturing fog only works where mountains, ocean humidity and very specific atmospheric conditions coincide. Still, the image is powerful for a planet increasingly affected by water scarcity: as wells empty and temperatures rise, there are entire communities in Morocco that have literally begun to harvest clouds to survive.
