demography

Say an alien race conquered Earth and confined the human race to a reservation in Australia. How many people could the area support?

Australia has very low rainfall so water scarcity is a serious problem. Humanity would have to run desalination plants to truly support the population. We would need massive solar farms as well.

It would seem like agriculture would fall short of demand and people would starve. But eventually a large fishing industry could thrive and diets would be more seafood-based. We could even irrigate tracts of land with the desalinated water.

Australia seems to have large and diverse mineral supplies, but are we missing any key ingredients of modern industry in Australia? What other measures would we take to adapt? And ultimately, what would be the future of humanity, confined to Australia ?

I am also interested in recently published comparative papers. I need good examples for a paper I want to write on US/Canadian refugee comparisons.

Hello! I am currently a first-semester student of MPH. I have been given a task to understand how to use a lexis diagram to calculate mortality risk, especially focusing on DHS surveys. I have gone through many documents and videos but I cannot understand and feel dumb. Would anyone be able to help me understand it?
