Co-Creating Water Futures: Perceptions of Fog Harvesting in the Atacama Desert

Given the increasing water scarcity in northern and central Chile, characterized by declining rainfall, rising temperatures, and growing water demand, it is crucial to explore alternative sources that can supplement traditional water supply systems. One such source is fog water, which is available along an extensive stretch of the Chilean coast. Fog collectors allow for passive harvesting of this resource.

Chile has been a pioneer in researching and developing fog water harvesting technologies, and has several notable experiences in this area. However, despite its technical and environmental potential, fog water harvesting is a relatively unknown technology that has scarcely been studied from a social perspective. Significant gaps in knowledge exist regarding how communities perceive this water source.

This project advances the understanding of fog water as a complementary source in drought-stressed territories by examining social perceptions and local experiences in the Atacama Desert. The project presents illustrative cases and preliminary findings that highlight factors such as local memory, trust in the technology, and the perceived value of fog water. By focusing on social and subjective dimensions, the study addresses a significant knowledge gap and provides preliminary insights into the interplay between water, technology, and territory under conditions of climate stress.
