Years ago, the Ghaddafy regime started using irrigation from so-called fossil water, and had reached the same conclusion about dams in arid areas that has been reached by Morocco, Central Asian ex-SSRs, etc.
What conclusion would that be? (Seriously, you don’t say, so I don’t know what you’re saying is the conclusion about dams)
Just one dam thing after another?
Salinity rises in the soils and aquifers. Worse case may be the Aral Sea, but the Aswan High Dam has had a largely negative impact.
