Situated within the south of the Coquimbo area, 300 km north of Santiago, Peña Blanca is struggling a brutal drought and faces the specter of turning into a part of the Atacama Desert by 2050, the United Nations Convention to Combat Desertification (UNCCD) warned two years in the past.

¨In Peña Blanca till 2000, water ran off the floor, and the villagers had dikes to take turns to make use of the water,” Nicolás Schneider, a geographer with the “Un Alto en el Desierto” (A Stop in the Desert) Foundation, the NGO behind the set up of fog harvesters within the area, informed IPS.

The official report of rainfall within the municipality of Ovalle, within the basin of the Limarí River, the principle river in Coquimbo, signifies an annual common of simply 102.6 millimetres within the final 30 years.

However in 2018 the common fell to 38.1 mm, and in 2019 to only 8.5 mm. In June, three non-consecutive days of rain have been greeted with pleasure as a result of they totaled extra rainfall than in all of 2019.

Coquimbo is residence to 771,085 folks, 148,867 of whom dwell in rural areas. It’s the southern border of the Atacama Desert, the driest desert on earth which has probably the most intense photo voltaic radiation on the planet. It encompasses six northern areas on this lengthy, slender nation that stretches between the Andes Mountains and the Pacific Ocean and has a inhabitants of 18.7 million folks.

“I’m a livestock breeder and I additionally organise occasions for delegations that go to the fog nets in Cerro Grande,” Claudia Rojas, who at 53 is making the shift from livestock elevating to a tourism microenterprise, informed IPS.

“I used to be born and raised in Peña Blanca and I would not change it for another place. Now I’ve only some goats (20) and sheep (60). I had as much as 200 goats however I’ve been lowering the herd as a result of there may be not sufficient pure pasture,” she mentioned.

“I hope to proceed receiving delegations when the pandemic is over. I serve them cheese, roasted child (younger goat) and native merchandise. At my home or within the reserve,” she mentioned.

What Claudia loves probably the most are the visits by lots of of schoolchildren “who’re blissful to see nature.”

“From up above they’ll see the (Andes) mountain vary and on the opposite facet the ocean. The principle attribute right here is the fog. And they’re amazed when the fog reaches the hill and so they see how the water is harvested,” she mentioned.

The Agricultural Neighborhood of Peña Blanca, made up of 85 households, has 6,587 hectares, 100 of which represent the Cerro Grande Ecological Reserve, the place the fog harvesters have been put in 15 years in the past. Again then, many locals couldn’t think about the impression and advantages the nets would have.

“They’ve made us well-known and that has introduced the group sources for different tasks,” mentioned its president, Daniel Rojas, 60 (no relation to Claudia or different sources with the identical surname, which is widespread within the space).

In Chile, the “agricultural group” is a authorized determine for the collective property and usufruct of the land, by which the group members are given parts of land to make use of whereas one other half is collectively managed.

“We’ve harvested a big quantity of water that has helped us in tough instances. At first to irrigate the vegetation and reforest with native species, after which to water the animals. We constructed a consuming trough, piping the water two km downhill.”

“Later, a 10,000-litre tank was made to gather water for folks dwelling close by, to make use of when the tanker truck doesn’t come,” he mentioned.

Eight years in the past, Peña Blanca beer started to be brewed, made with fog water, which is softer. Its gentle (Scottish) and darkish (Brown) variations competed on the 2015 ExpoMilan and gained the viewers award.

Mario Alucema, 59, additionally born and raised in Peña Blanca, works within the artisanal brewery.

“Our beer made with 100 % fog water is fashionable and profitable. It has drawn consideration to our farming group. I work (within the brewery) each (southern hemisphere) summer season and obtain 30 vacationers a days, from Argentina, Brazil and different international locations,” he informed IPS proudly.

The plant produces 2,500 litres every week, and manufacturing is ready to extend as a result of the plant might be expanded.

“When these younger entrepreneurs confirmed up I mentioned to myself: ‘Who’s going to return all this fashion for the beer?’ We’re a good distance from the Pan-American Freeway. Then I assumed, ‘Who’s going to drink this beer?’ And third, I assumed it was cash laundering. However the whole lot was the opposite method round. At this time, within the midst of this international pandemic, they’re nonetheless coming for the beer,” he mentioned.

Daniel Ogalde, 47, who can be from Peña Blanca, has been the park ranger since March. He’s devoted to the upkeep, irrigation and replanting of native species within the ecological reserve.

“My concept is to be right here for a very long time. Due to the coronavirus, visits are suspended, however in August we plan to restart them,” he informed IPS, including that the reserve “is a supply of delight for the group and everybody is worried about its care and upkeep.”

Guido Rojas, 58, lives in Peña Blanca however works on the close by lookout level on the Talinay Wind Park, owned by the ENEL Green Power company. “Harvesting water helps us as a result of there have been many dry years,” he mentioned.

The expertise “has been maintained by the help of the group and the individuals who dwell right here,” he added.

A qualitative leap has been made since July. The United Nations Development Programme (UNDP) has granted 40,000 {dollars} to renovate and construct fog nets, set up lookouts, paths, signage and bogs. The programme ends on Dec. 31.

Because it was created in 2006, the reserve has had 24 fog-catchers, with a complete of 216 sq. metres of double-layer 35 % Raschel mesh.

“The growth consists of the restore of 12 and the development of 16 new fog nets. We can have 28 totaling 252 sq. metres, to reap water,” mentioned Un Alto en el Desierto’s Schneider.

Now 1,537 litres of water might be harvested per day, he defined.

In a calendar 12 months, half of the fog water is harvested in September, October and November, when 20 litres/day are harvested per sq. metre, greater than 3 times the common.

Fog traps have been, in truth, an invention of Chilean physicist Carlos Espinosa, who donated the patent within the 1980s to the United Nations Academic, Scientific and Cultural Organisation (UNESCO), making it attainable for them for use in several international locations.

Fog catchers include wonderful mesh nets generally known as Raschel arrange on foggy slopes to catch suspended drops of water, which collect and merge, working from small gutters into assortment tanks.

The brand new programs have a design referred to as “comunero” and created by Schneider and Daniel and Guido Rojas.

They’re particular person buildings of 9 sq. metres every which have a number of benefits: they’re cheaper, simpler to move and to take care of and if anyone suffers a flaw the others proceed harvesting water.

They’re anticipated to stay totally operational till 2028.

The primary fog-catching challenge in Chile was within the mining city of El Tofo, in a area north of Coquimbo. But it surely was deserted within the 1990s. In Coquimbo, there are different services for harvesting fog water, for particular person and collective use. However none are as well-known as Peña Blanca’s.

In Alto Patache, close to Iquique, within the far north of Chile, there are fog traps that harvest seven litres a day per sq. metre, however the challenge is for scientific analysis. In the meantime, in Chañaral, a municipality within the Atacama area, there are fog catchers whose water is bottled and in addition used for aloe vera manufacturing.

In line with Schneider, the fog catchers “will be replicated alongside your complete coastal strip between Papudo (centre) and Arica (far north), which is greater than 2,000 km” of this South American nation’s 6,435-km shoreline.

“They’re actually helpful for remoted areas, fishing coves and scattered populations uncared for by public spending. And they’re crucial for combating desertification as a result of a lot water will be harvested in springtime, to make use of within the sizzling summers,” he mentioned.

The issue standing in the way in which of increasing the usage of fog traps, in response to Rojas, the group president, is the dearth of presidency funding for this expertise and its implementation.

“We’ve numerous coves which are solely equipped by tanker vehicles. Maybe fog traps should not the full answer, however they may help rather a lot when water is scarce,” as is the case in northern Chile, he argued.
