    As a mountaineer, I have always been fascinated by nature.
    Since I was a teenager I know about this book by Johan Van Lengen it is indicated in some design colleges. We have a Portuguese version here. If you don’t know, it’s worth checking

    Hi Marbelo, do you have a copy to share with us?
    Here it is in English, now in the Avalon Library.
    Thank you very much Bill, now everyone can have access to this fantastic book
    Marbelo,
    thanks so much for the barefoot book;
    just started but every word is a gift.

    (and thanks to Bill for adding it to the library

    Discoverd a YouTube channel earlier today which is called Nomad Architecture

    It seems to cover building shelter in all types of environments from cold to hot. Might prove useful or inspirational?

    A couple of examples...

    Here’s a guy I watch, David in South Carolina, of the David West YT channel. “Glad you joined me on this one, weee’ll.. join you on the next one”.

    Old school fire making methods. This one is about a tweak to hand drilling.

    Just above the box where you type your replies there are a load of icons. Bold, italic etc. Keep scanning right and you will see an icon that looks like a little strip of film.

    Essentially it wraps [vedeo]video link goes here[/vedeo] tags around your (highlighted/selected) link. (The word video is deliberately mis-spelt).

    I stumbled on this video about collecting water using 'fog nets' in Peru and thought it was very interesting -

    it's primitive in the sense of simple and basic - the net used looks exactly like the green nets used to bag up vegetables like carrots... so it's already widely available, nothing fancy -

    (3:16)



    Desert Fog Nets Catch 10,000 Liters Of Water Daily

    Quote These fog catchers in the Atacama Desert, Peru, also known as the driest place on earth, capture 10,000 liters of freshwater a day for drinking and growing sustainable food.

    collecting water in times of crisis and societal collapse would be the basic life saver before everything else -
    and it doesn't get more basic than this - running/moving around a field collecting dew with cotton material (in the case of this video tea shirts) tied to your trouser legs..

    How To: Collect Dew for Drinking Water

    Quote Hosted by Command Sergeant Major T. S. Decker (ret.), this series provides some helpful “how to” information. In this episode, Decker demonstrates a simple method of collecting dew for drinking water in a survival situation.

    Amazing fog catchment, we once collected dew using a black construction canvas (the cheap ones) and a bucket, it is very humid where I live, my roof is dripping right now, if I put a small bucket outside, tomorrow morning it will be probably half full.

    It is indeed a great "underestimate" solution for water catchment.

    4 different ways to harvest water in dry/arid land.

    1 - Check dams or rock dams - it is a well known method used in permaculture to cultivate plants around the dam area, it also helps prevent erosion.

    2 - Fog nets and fog irrigation systems as mentioned in the posts before. Sometimes wrongly called mist system (this one is just a sprinkle that irrigates plants (it does not collect water, it uses water from a water tank), also very used in a mushroom houses or greenhouse when humidity index is too low).

    3 - Bioswale is a technique used in gardens, but it borrows the idea of the old swales systems (used in large fields to prevent erosion), the swale can store water in the ground making it possible to plants to grow in that swale's area. Usually you need a little slope for that, otherwise it wouldn't work, when you see erosion, one of the first things that comes to mind is to build a swale to correct the water runoff.

    4 - Zai holes (aka demi lunes or half-moon, also called BUNES) - it allows to restore very arid areas as in the country Niger, they already turned desert land into crop land using this simple technique to store water from raining. Niger is basically a desert, the entire country is in the Sahaara desert region. The idea using this technique is to store water in these semi circles holes and then plant crops on it, reducing water runoff and trapping the little rain in there. Here is a short video showing how they do that:



    It is claimed that this technique works with even less than 6 inches of rainfall per year, Mauritania is another country testing it.

    * Gum arabic tree, seems like a perfect tree to plant in desert areas, it fix the nitrogen problem and also provide excellent resin and fire wood.

    Note that these techniques mentioned above are not used for drinkable water, except for the fog net catchment, but still possible to do filtration using charcoal and sand.

    Anyway It is quite a lot of hard work, and seems to fix the water problem allowing people to farming in their local areas instead of migrating somewhere else.


    [update]

    Here is a much better video of the Zai planting holes, explaining in more details.
