You didn't watch the video, clearly. They're incredibly simple projects that help permanently convert land from desert to arable. They're not dependent upon the outside for anything except directions, as the only tools needed are what the people already have, a pickaxe and shovel. Once started it can continue on with nothing but locals who want to take more land back from the desert.

Nomads, landmines, buzzwords, you're just looking for edge cases where this fails, and that's not helpful. If it works for 80% of the land they look at, that's mre than good enough.

Don't look at the now, the moment, look at the long run. If they had missionaried for a religion that creates a reverance to natures creation and destruction for self-gain as a colonial, anti-god ideology, that would create longterm prospects for this to survive. If they had planted plants poisonous to goats and sheep, this could have endured longer. If they made this sort of work a yearly festival. That would have done more then a incentive driven strawfire.

Please don't pretend religion has any answers to any real world problems, it just causes problems.
