Just watched your "Greening the Desert" video - thanks for putting it together!
First of all, love the idea of doing a bunch of videos on basic permaculture principles. More materials going mainstream is always good.
Jennifer Wadsworth wrote:With regard to the video presentation (and again - I only watched the greening the desert vid) - I would say you need the following for more impact:
--images of greening the desert projects (there are probably a couple dozen that come easily to mind)
Jennifer Wadsworth wrote:
--simplify the math (I'm a number nerd too and people's eyes glaze over when you deal too specifically with very specific large numbers. Try rounding). You can always publish a go-along pdf that has the hardcore math in it and people can choose to read it or not.
Jennifer Wadsworth wrote:--you need some kind of diagram to show where deserts are, types of deserts, etc. As you noted, not all deserts are equal.
Jennifer Wadsworth wrote:--another point that I have to look into further myself is if those carbon numbers really hold true across all tree types. Here in the hot desert where I am there are not really any native broadleaf trees. Native trees have certain ways of dealing with harsh "hot desert" conditions and I wonder if they sequester carbon at the same rate as broadleaf trees. Also, hot desert trees are typically much smaller than trees in other areas - more like large bushes - most topping out at under 40 ft.
Jennifer Wadsworth wrote:--then there's how to water the trees. One always has to understand where water is going to come from in order to get these trees through the establishment phase (usually about 2 yrs). This is why all sorts of water harvesting from the macro to the micro are beneficial and are needed support systems for regreening efforts.
Jennifer Wadsworth wrote:--for broad scale reclamation of desert into more productive systems, one might also have to look at imprinting, either by machine or by holistic range management or perhaps keyline plowing
Jennifer Wadsworth wrote:--there is also the school of thought that deserts actually perform a useful function in that they are part of the albedo effect, reflecting the sun's rays back into the atmosphere (which is what the ice caps do as well). With the loss of polar ice as a reflector, some argue, increased desertification is filling that niche. There's evidence against this theory too.
Jennifer Wadsworth wrote:Overall - you have a very pleasant speaking voice, you seem knowledgeable and sincere - all great things. You just need some more visuals that illustrate some very clear learning objectives supported by facts that have been distilled for clarity. (forgive me - it's the instructional designer and systems analyst in me!)

Cal Skins wrote:This is a really good point. Purely out of curiosity, do you think that the climate could change in a desert if there were enough trees so that more rain would fall? I'm thinking the trees would have an impact on the climate because the ground is holding more water and allowing the temperature to lower, the trees offer shade and temperature variations and they also transpire, putting more moisture into the air.
Then my thought is that it would be possible to change the climate of a desert to something more tropical or temperate. Of course this would take years to accomplish and a major scale effort.
Cal Skins wrote: (Regarding Water Harvesting) Very true. That would be a great topic for a video.
Cal Skins wrote:This is the first time I've seen imprinting! That is so cool! It looks like a mechanized method of Yacouba Sawadogo's methods of digging holes to collect water and spreading seeds inside them. Very cool.
