They are identifying some functions, but I expect some of the plants featured, stack functions. For example, they suggest that Blue-Bunched Wheatgrass funnels water to it's core, however the dried stems sticking up, likely also trap winter snow and slow it from blowing elsewhere. Some Humans are starting to think along those lines and are planting intentional plants that will remain standing as snow-fences.
Capturing the water from air conditioners: "Insane, yes, but I guess that there is at least as much air conditioning capacity than that in the Canadian Okanagan. 15,000,000 gallons of water a year. If you’re going to waste electricity, you might as well get the water."
I am near the ocean, and during our wet winters, we use a dehumidifier in the bedroom both to dry the bed, and to dry the shower room. We empty the dehumidifier reservoir into buckets. Then when we want to do a load of laundry, we pour the buckets into the machine, add a bit of soap and all the clothes, and let it run. We haven't tried to catch it at the rinse cycle yet, as it's not in a convenient spot for that, but if we needed to, that would be another level of water reuse. However, we dry the clothing near the dehumidifier also, so the water goes around and around!
Dehumidifier and air conditioning water lacks the minerals found in well water. That's likely to affect its taste for drinking, but if house water systems were designed for both potable and less potable options, water can be used more efficiently.
They also talk about water collecting monoliths. I recently watched an interesting video about archaeology in a dry area of the Middle East. They were able to use a drone with special equipment to identify a great number of small water reservoirs that Humans had built in cliff faces before the Pyramids of Gaza. Very simple gravity fed collectors that saved enough water from the rainy season for year round crops. There was evidence of many other water and soil collecting systems that are being rediscovered and put to use in permaculture.
"...by adding a stone and planting against it, where water and heat can both be concentrated. One can grow crops out of season, extend seasons, and grow crops that otherwise would not survive." Again, I recall reading historical records of this technique being used on Easter Island.
However, some things I think are equally important to consider:
1. Beaver people are experts at harvesting water, and we need more of them in BC.
2. Nature plants poly-cultures and Humans tend to plant mono-cultures. Many of the images in the article showed exactly that. There are farmers who are learning and following Nature's example and doing well because of this approach.
