    A one man effort in cold desert.
    2 key successful methods are:
    1. 'swale on contour' - to keep water in the root zone of new plantings by capturing it in the 'swales'
    2. plantings are close together to provide mutual shading and soil moisture retention.


    once established, water is trapped in the soak. and water percolates through to depth.

    Sounds like he has near permanent water availability. Initially I thought the swales did all the hard work in capturing just local available precipitation, but I think its a little more organised than that.

    it uses a lot less water. same method used in projects in Africa (the farmers using intensive irrigation can't do it without the intensive water supply) The point is it is very efficient use of limited water supply. Once you get larger forested areas the evapo. thing helps. can't expect miracles that defy the laws of physics.

    the swales when mulched and shaded properly do retain the moisture better allowing it to sink in deeper. grasses ground covers and a tree canopy.

    otherwise you face the expensive prospect of energy intensive desal. and long range canals or piping...to water the crap out of dead soils with energy intensive artificial fertilisers- maybe the runoff from that can achieve something useful...like flow into natural waterways :lol:

    anyway. he isnt growing crops. there are farming methods using same swale on contour principle.

    'their way' of cropping requires more energy and more water (and a benign climate) ...good luck to them.

    still rockin their monocrops. Europe had a couple of 'bad' seasons.

    Scared of bringing a child into this changing world? You're not the only one.




    Reconsidering having kids because of climate change? You’re not alone
