Any possible method we use to collect water from our surroundings will affect dependent microclimates and ecosystems. The same could be said about building reservoirs, or even collecting rainwater. The question is "to what extent"? Unless you can present some evidence that fog harvesting is truly disruptive, I'm going to assume it's not much different from collecting rain, ie. has minimal impact. I haven't found any papers suggesting differently. Surely these things aren't very efficient, and therefore any one of them is pulling a tiny fraction of water out of the air. I mean, just think about the height of a fog cloud, and realize they are only scraping a bit of water out of the bottom 10 feet of that air column! Certainly it must be better than draining the Colorado river before it reaches the ocean, as we do currently.

Plastic nets that can be erected by anyone, anywhere are somehow worse in this regard than a centralized municipal water supply?! Or a dam that takes millions of dollars to build? Quite the opposite. These things are practically the definition of a decentralized technology.
And, cool video, but your proposed "better solution" seems nonspecific and naive. The problems are different in every ecosystem, and therefore, so are the solutions. These nets are only practical in certain environments which receive regular fog, and wouldn't make sense in Yellowstone. Likewise, all the wolves in the world won't make it rain more in the Atacama. The problem is precipitation, not erosion.
- briantakita 11y agoThank you for your response. I would like to take back the inferences I drew re: centralizing supply. I'm a bit sensitive over some governments making rainwater collection illegal & ecosystem-friendly landscape design; due to some of my affected law-abiding friends having issues with it. > The same could be said about building reservoirs, or even collecting rainwater. That's true. Responsible water stewardship requires systemic discipline that is case-specific. One of the principles of regenerative agriculture & similar philosophies (i.e. permaculture) is to create edge effects to create the context for a more robust ecosystem. Pooled water, especially when designed to maximize edge effects (i.e. increasing the circumference of the shore), is a tech that contributes to creating robust ecosystems. Harvesting fog seems to fit in many circumstances. > These things are practically the definition of a decentralized technology. Well said & I agree. Harvesting fog seems like a legit tech option in concept. > And, cool video, but your proposed "better solution" seems nonspecific and naive. I was illustrating an example of how a small change has ripples. If history is any guide, tech (technology & technique) has unexpected benefits & drawbacks. Every ecosystem is different. As you said... > The problems are different in every ecosystem, and therefore, so are the solutions.
