Pandanus looks sort of like the yuccas that I have. Sounds like an experiment to try. Yuccas can grow in the desert, but they also thrive in the humid south. They stop human traffic because each one of the leaves has a very spiny thorn at the tip. I have a bunch I need to move, one of these days when I feel brave enough to handle them. Ill see if their remains make a good home for some other less dangerous plants!
i was looking at Israels water problem. The high tech solution was to pipe in water from the Mediterranian Sea. The pandanus method sounds like a tropical version of hugelkultur.
