The report was only for world surface water (1) and did not get into the fact that most of the rest depend on aquifers that will be dry at or before 2040 (2), like our Ogallala. Also not in the report is the effect the pollution and depletion of surface and aquifer water will have on food production.
Noting that irrigation gives six times the yields, this will be a large reduction in agricultural output (3) along with the lack of pure water supplies. Global warming only makes it worse (4), as does the increasing over-population(5). Peak oil also affects agricultural output and distribution(6).
Six things that will profoundly affect the world of 2040, preceded by other effects such as economic depression from increasing prices, and lack of jobs, with instability.
They all tie into each other.
Higher food prices from higher prices of ever more scarce water, and rampant unemployment----all from moslem North African and Middle Eastern overpopulation, have already led to instability in the region and higher prices elsewhere.
Getting away from protein sources that use excessive water, like beef, or are causing fisheries decline to zero in the oceans, are necessary to mitigate the effects of the population crash.
The six riders of the apocalypse are approaching, and the hour is getting late...........
