Find photos from installing drip irrigation in the RISE Permaculture Garden here.
RISE staff and work study students installed drip irrigation in the RISE Permaculture Garden yesterday. The drip irrigation will be used to help the trees become established. Drip irrigation delivers a slow drip of water directly to a plant's roots reducing evaporation, runoff, and water waste associated with other methods of irrigation such as flood and sprinkler. The goal is to compare the drip irrigation to the buried zirs, a passive vernacular method of irrigation. Zirs are large versions of ollas, unglazed clay pots. These zirs were buried and are regularly filled with water. This water then migrates through tiny pores in the zir into dry soil through a process called osmosis. Water will leave the zir only if the surrounding earth is out of equilibrium and is drier than the zir, maintaining a consistent state of damp passively. The zirs also significantly reduce evaporation, because the water is stored and released underground away from sun and wind. Subsoil irrigation also helps encourage plants to grow deep strong roots, a must for surviving in harsh desert climates.
This is how ollas and zirs work theoretically. In practice execution is more complicated. In the RISE Permaculture Garden the soil is extremely sandy. In fact, it is just sand with surprise pockets of compost from a past land use. Sand is ideal for drainage, but not for absorbing and retaining water. Because of this, our zirs drain much more quickly than desired. Due to lack of organic matter, water is likely not being absorbed laterally as much as needed to reach the new trees’ roots and provide for ground covers. We need to focus on soil creation before the zirs can reach their full potential, but we are optimistic about the benefits they could provide.
Through trial, error, and research RISE aspires to develop its knowledge about the best permaculture practices for Egypt and similar arid climates in developing countries. Anyone interested in supporting this effort should contact RISE at [email protected].

Note: The various badges displayed in people profiles are largely honesty-based self-proclamations by the individuals themselves. There are reporting functions users can use if they know of blatant misrepresentation (for both people and projects). Legitimacy, competency and reputation for all people and projects can be evidenced and/or developed through their providing regular updates on permaculture work they’re involved in, before/after photographs, etc. A spirit of objective nurturing of both people and projects through knowledge/encouragement/inspiration/resource sharing is the aim of the Worldwide Permaculture Network.
A member is a permaculturist who has never taken a PDC course. These cannot become PDC teachers. Members may be novice or highly experienced permaculturists or anywhere in between. Watch their updates for evaluation.
One of these badges will show if you select your gender and the "I'm single, looking for a permaculture partner" option in your profile.
People who claim to have taken a Permaculture Design Certificate (PDC) course somewhere in the world.
People who have entered an email address for the teacher of their PDC course, and have had their PDC status verified by that teacher. Watch their updates for evaluation.
People who’ve taken a Permaculture Research Institute PDC somewhere in the world.
People who claim to teach some version of PDC somewhere in the world.
With the exception of the ‘Member’ who has never taken a PDC, all of the above can apply to become a PRI PDC Teacher. PRI PDC Teachers are those who the PRI recognise, through a vetting board, as determined and competent to teach the full 72-hour course as developed by Permaculture founder Bill Mollison – covering all the topics of The Designers’ Manual as well as possible (i.e. not cherry picking only aspects the teacher feels most interested or competent in). Such teachers also commit to focussing on the design science, and not including subjective spiritual/metaphysical elements. The reason these items are not included in the PDC curriculum is because they are “belief” based. Permaculture Design education concerns itself with teaching good design based on strategies and techniques which are scientifically provable.
PRI PDC Teachers may be given teaching and/or consultancy offerings as they become available as the network grows.
