I am skeptical of most of these predictions. History is littered with what were once accepted demographic and climate predictions that were widely accepted and now look foolish. The populations of Europe and Japan are already falling and N. America is growing solely due to immigration. Birthrates are falling almost everywhere. Ag tech has meant that the food shortages predicted for decades have never materialized. In fact there are billions less hungry people now than there were a few decades ago.

I can remember when scientists were saying that another ice age was coming. They also said the Prairies was facing perennial droughts, the Antarctic ice cap would melt, polar bears would become extinct and we would have more hurricanes. So far the reverse has happened on all of these.

Edit: Also desalination tech has really progressed. There should be plenty of water for drinking at least. It may never be feasible for irrigation.
