Farmers in northern Chile, one of the driest regions in the world, are learning to adapt to drought after discovering a new source of water \u2014 fog-catching nets.<\/em><\/p>\n

\"\"<\/a><\/p>\n

Since December last year, the Coquimbo region of northern Chile has officially been suffering a drought emergency, and this is just the latest in a succession of parched years. But\u00a0a surprising source of water is helping local farmers adapt to ever-drier\u00a0conditions.<\/p>\n

Villages in the region are typically made up of shacks with no running water. For electricity, these communities\u00a0sometimes need to use a generator. They rely on the local government to deliver water in trucks, but\u00a0say it isn’t enough to meet their needs.<\/p>\n

Good years and bad years<\/h2>\n

Jose Ossandon lives in the community of Los Tomes with 19 other families. Most of them keep animals \u2014\u00a0cows, horses, sheep and goats.<\/p>\n

“In the good years when we have rain, we can sell our livestock at a decent price,” Ossandon told DW. “But in the bad years, when there is no rain, it’s a lot tougher because there is no food for the livestock and we have to sell them for a bad price.”<\/p>\n

As a result, many people from the region have migrated up north to work in the mines, or down south where there is more pasture for their animals. But Ossandon, who is president of the local community, chose to remain. He still\u00a0loves the\u00a0tranquility of the\u00a0scrubby, mountainous landscape where his family has\u00a0lived for generations.<\/p>\n

\"\"<\/a><\/p>\n

And now, technology to capture water from the atmosphere offers new hope for Los Tomes. The Catholic University of the North chose several rural communities with the right conditions to try out its fog-catching nets.<\/p>\n

Harvesting fog<\/h2>\n

Daniela Henriquez works in public policy at the university and is one of the people in charge of the project. “We chose communities that are 25 kilometers\u00a0[15.5 miles]\u00a0or nearer to the sea because that is where we get the best fog,” she told DW.<\/p>\n

The process is relatively simple: The fog catchers are installed on top of a nearby mountain where the wind\u00a0pushes airborne moisture\u00a0through the nets. The water then drips down to a plastic gutter at the bottom of the net, and into a pipe.<\/p>\n

“We have two fog catchers which feed into a water trough for our livestock,”\u00a0Ossandon says. “We’ve had very good results from it.\u00a0The animals have clean water and they can stay up in the hills in their pasture and don’t need to come down to the village for water.”<\/p>\n

From the hills close to Majada Blanca a sea of fog is visible. Now the community can make use of that water
\nThe water tanks are scattered through the hills to encourage the animals to feed from new areas of pasture. There are also plans to use the fog water to grow more pasture.<\/p>\n

Depending on the density of the fog, 1 square meter\u00a0(10.7 square feet) of net can produce between 2 and 7 liters (0.5 and 1.8 gallons) of water per day. The nets here are 60 meters square. In the midst of a severe drought, this extra water has been very useful for Ossandon and his community.<\/p>\n

Living\u00a0with\u00a0drought<\/h2>\n

The cost of a single net,\u00a0including\u00a0installation, is around $8,000 (\u20ac6,827).\u00a0The community wouldn’t be able to fund the project on its own. Most people in these mountain communities barely survive\u00a0on around $100 to $200 a month, well below the minimum wage.<\/p>\n

The Catholic University of the North and the local government are funding the project with the aim of testing the technology while preserving the region’s rural way of life by helping people adapt to\u00a0the changing conditions.<\/p>\n

\"\"<\/a>

Henriquez stresses the importance of the community eventually taking over ownership of the project and deciding how the water should be used.<\/p>\n

Los Tomes uses the water mainly for\u00a0livestock. Majada Blanca, another community testing the fog catchers,\u00a0has\u00a0fenced off a parcel of land that now contains six rows of olives trees. High up on the mountain, the square\u00a0nets provide the\u00a0trees with much-needed water.<\/p>\n

“We used to look at the fog up on the hills, but we never guessed that we could actually use it,” Ricardo Alvarez of Majada Blanca told DW. “And then someone came from the Catholic University of the North who was experimenting with ways to use fog and this has helped us with our olive grove.”<\/p>\n

Once the olive trees are mature, the community wants to make olive oil to sell to local supermarkets. They\u00a0say\u00a0it will be the first olive oil made using fog water.<\/p>\n

Drawing\u00a0back the youth<\/h2>\n

Because of the drought, young people in particular are leaving these communities. Alvarez hopes they will come back to\u00a0help with the olive oil business.<\/p>\n

Jorge Velasquez has returned to his community to launch an ecotourism business<\/p><\/div>\n

In Los Tomes, Ossandon’s son is the last pupil at the local school because so many families have moved away.<\/p>\n

There is better news in the communities of Lorenzo Peralta de Punilla and Peral Ojo de Agua de Punilla, where the fog-catching nets are already inspiring young people to come home. Jorge Velasquez\u00a0and his brother Salvador\u00a0are among them. They have started an ecotourism business.<\/p>\n

“We came back here because we really love the wildlife and flowers that grow here and we want to teach tourists about them,”\u00a0Jorge Velasquez\u00a0told DW.<\/p>\n

With\u00a0their community’s support, the\u00a0brothers have created a nature reserve watered by the fog net. They hope to get more nets\u00a0to provide drinking water.<\/p>\n

The ability to adapt and regenerate is key to these communities’\u00a0survival.\u00a0This\u00a0project is just starting out, but the hope is that it will help them live with the ongoing droughts.<\/p>\n
