To me the ideal of using technology like this is a brute force solution. I'm always suspect of the scientific credentials behind the permaculture movement but I suspect that they have got this one right. Slow water down high in the landscape, let it absorb into the ground, build leaky damn structures and many of the water security issues go away. I think this has been proven fairly well in a number of semi-arid areas such as parts of India.

I've recently seen a video on YouTube where they did this. They dug a "hole"/artificial lake with a capacity of over, I think, 140 million litres.
They used that to create "a wet spot" which slowly started to transform the surrounding landscape. Plants, trees, bushes obviously started from around that lake but moved farther and farther from it as the soil became better.
This does not solve any problems with salt water, but it could possibly a solution for areas where there's "only" very little water available.
