> ... will kill the downstream deltas By stripping off the alluvial soil ... It clearly won't. The article/video discusses how a) the dams are low profile and allow most water to flow over the top -- they are designed to trap sand while allowing alluvial material over / through, and b) they're also designed to fill within a few years which means the bulk of alluvial material in subsequent events will bypass the site entirely. > There is a reason that much of this planets life comes from delta regions ... Can you explain what you mean by this please? > Instead of attempting to make every region on the planet farm land, we should focus on solutions that take into account a balanced ecosystem, and where that can't be achieved, relocation the human population. I appreciate your point of view here, though I'm now curious where you happen to live and how you'd feel about being forcibly relocated if/when climate change renders your home unlivable without being modified. I'd suggest that much of this work is trying to recover recently ruined, or maintain currently precarious human habitations, and perhaps halt the desertification of currently habitable regions.
