Reversing Desertification with Gabions


  1. Another good video that taught me once again as you have for years. Thanks again. When & how much is the next online PDC?

  2. Very nice. Would like to hear Geoff talk more about Induced Meandering in relation to gabions. Seems to me that they could be complimentary: gabions higher in the landscape with induced meandering in the floodplains to free water courses of incised channels.

    PS- would be nice to be able to comment on the video pages without Facebook, Yahoo, AOL, or Hotmail. Google integration would be nice!

    1. i second the comment about facebook and twitter. i don’t see the point of those social networks in particular, and a regular email handle should suffice…!

      1. We are trying to reach the largest audience with the lowest input effort but with the highest quality production product on the smallest budget.
        The combination we presently use is our refined best so far and we are tracking the results.
        I am sorry if it is not the best for you but we are trying to influence the status quo.

  3. geoff,
    just out of interest:
    is it wise to block the path of flooding water with large(r) rocks ‘n stuff, and eventually plant valuable trees alongside in the face of the possible event of that flood returning to the same spot every now and then? here, where i am, we have people loosing houses and properties from annual floods, because everybody seems to like living close to the river banks, and everybody ignores the risks involved!

    i gather the answer is probably in the design details, but still: you’re dealing with areas subject to annual floodings, right?

  4. Jeff,
    On our new plot we have a 5-20cm rill that is dry most of the year. Brussels, zone 8, humid. Our pond (r=6m, 1,5m deep) spilles like mad. The rill (slope 5-15%) is washing out a deeper scar during the heavy rains this winter. We think about micro-gabions of 0,5-1m… Swaling into lateral trenches… Soaking in even more water? When is to much to much? Letting it run is somewhat contre coeure. And for more ponds we dont have the space.

    1. Swales are tree growing systems or at least perennial growing systems and these planted to useful species should take up most of the water.

  5. Sorry if I came across as ungrateful. I think you all are doing an awesome job. If you have to choose between different platforms, Facebook would seem to be the most bang for your buck!

  6. Good stuff. I’m on the side of a mountain here and use terraces with rock walls on the downward edge too and they have stopped all erosion. Sometimes the rainfall can be up to 100mm in an hour and the rock walls handle any and all water flows. Incidentally, I’ve been adding mulch and compost to the downhill side and planting those up too. That tends to work here and those beds on the slope require far less water during summer than any system other than the swales. Top work and thanks for the great videos. Chris

  7. Hi Geoff,
    is this river, between the rocks on the front cover of the main video and in the picture above, in Jordan? And this flashflood (2min48s)? And the last question: This big terrace (9min38s) is this in the Loess region in China?
    Thank you for your answers!

  8. Geoff,
    Just found this and watched it, and was wondering how to use this in relation to sheet floods of the American Southwest on a nearly flat surface. I have some ideas but am not sure if I’m right. Also is there a DVD/CD PDC course? Thanks.
