IDRC REPORTS: Clouds on Tap: Harvesting Fog Around the World by Pattie LaCroixThe idea of harnessing fog as a source of drinking water has been studied for decades, but it wasin the mountains of the arid coastal desert of northern Chile where it was first put into practice.In 1987, there were 50 fog collectors — each one 4 metres wide and 12 metres long — locatedon a ridge line above the fishing village of Chungungo. Today, a total of 88 collectors areexpected to provide more than 40 litres of water per person per day — compared with just 14litres before the project began. The collectors are managed by a local committee, which chargesa small fee to each household. If a household greatly exceeds the average monthly waterconsumption, the fee is much higher."This project was always designed to supplement the existing water supply, which was truckedinwater," said Pilar Cereceda, the project leader and a professor at the Pontificia UniversidadCatolica of Chile. "But during the first year of the project the truck did not have to come to thevillage. Even during exceptionally dry years, the truck has only had to come from time to time.So now we believe that the main source of water for this area is the fog collectors," she told theVancouver conference.A village transformedChungungo has been virtually transformed by the presence of a dependable and affordable watersupply. Before the collectors were installed, the village population was estimated at 350 people.Many people had left Chungungo in hopes of finding a livelihood in larger cities. Some of themhave since returned and the population now exceeds 500. The fog collectors provide enoughwater for domestic consumption and for four hectares of community vegetable gardens, treesplanted along the main road in the village, and a public park in the centre of the village.One of the main conclusions of the Chilean experiment is that the participation of local people isvital. "It is so important to involve the community not only so that people know about theproject, but so that they are involved in building the collectors, in maintaining the collectors, inorganizing a local water committee, and in donating their labour to keep water costs at aminimum. This system depends on the clouds, but if people know how to use this simpletechnology and organize themselves well it will really work," stressed Professor Cereceda.Pattie LaCroix is a Vancouver-based writer. (Photo: N. MacMillan, IDRC)ERRATUM:When this article was first published no mention was made of the contribution made by theUnited Nations Educational, Scientific and Cultural Organization (UNESCO) to thedevelopment of fogcatcher technology. Indeed, had it not been for UNESCO's early support of adedicated group of Chilean and Peruvian professionals, it is unlikely this project would everhave come to IDRC's attention.http://www.idrc.ca/reports/prn_report.cfm?article_num=284 (2 of 4) [1/13/2005 12:49:15 PM]
