Life at Zaytuna – Swales in Landscape

Rob Avis, of Canada-based Verge Permaculture, explains how swales at the Permaculture Research Institute of Australia work to re-hydrate the landscape and re-charge aquifers.


  1. I noticed an oily residue on two of my lower swales yesterday and wondered where it had come from. Question answered. Thanks.

    I’ll get some pictures of my P-garden up soon.

  2. Rob,

    Great explanation of groundwater recharge and results on spring repressurization downslope.

    Keep up the permaculturizations here in Alberta.
