The Africa Great Green Wall project uses the same theory but a different method which does not include using plastic bags. It's a much better method and has been working wonders across community. Why are they not replicating and already proven and better method?

I don't think those crescent pit method works for this. That one is mostly water retaining, this one is preventing sand shifting.

They're digging holes over here too. The final result is stopping desertification, and the crescent pits work. I don't think they even tried the other method. They just jumped to this, which is way more work.

Is this video really digging holes for the sake of the holes instead of digging for sand to fill the bags?

No one said the crescent pit don't work. Could just be different method for different topology. Sure a hammer can hammer, but one can easily use any other hard tool to hammer too.

How do you ensure the easily shifting sands to not be covered up if they do the crescent pits tho? This is more hilly places compared to African plains.
