Synopsis
- This short video and accompanying article describe how Abel Cruz Gutiérrez uses simple nylon nets in Lima, Peru, to catch coastal fog to provide water for low-income neighborhoods.
- The video explores how the collected water, while not yet drinkable, represents an innovative nature-based solution to water scarcity in Lima, one of the world's largest desert cities.
- This video is in Spanish with English subtitles.
Teaching Materials
Prerequisites:
- Ensure students are familiar with the water cycle and the concept of water scarcity.
Misconceptions:
- Clarify for students that these catchers do not turn fog into water or extract water from fog, as fog is made up of water. They are providing a spot for fog, small water droplets in the form of a cloud, to be concentrated and collected in a more usable form.
Classroom Implementation:
- Use this resource as a hook for a design challenge project where students are looking for solutions to climate issues.
- Have students demonstrate their understanding by explaining the innovation, its importance, and the next steps.
Differentiation:
- To support students who struggle with reading automaticity, consider slowing the video's playback speed, allowing more time to read the subtitles.
Climate Change Connections:
- Explain that a warmer climate can hold more water in the air, making less of it available in water stores. Consider pairing the video with this lesson plan.
Interdisciplinary Connections:
- Geography:
- Discuss the climate of Lima and the factors that make fog-catching viable there.
Sustainable Development Goals Connections:
- Use this resource as an example of a solution contributing to achieving SDG 6, Clean Water and Sanitation.
This video describes the concept of a fog catcher and shows how they are used in some Peruvian communities. While water scarcity is not specifically mentioned, these fog catchers are an example of a solution to address the problem. It is important to note that these catchers do not turn fog into water or extract water from fog, as fog is made up of water. They are providing a spot for fog, small water droplets in the form of a cloud, to be concentrated and collected in a more usable form. The information presented is accurate, and this resource is recommended for teaching.
