Beneath Africa, Survey Finds 'Huge' Water Reserves
gambit3 writes with this news, carried by the BBC: "Scientists say the notoriously dry continent of Africa is sitting on a vast reservoir of groundwater. They argue that the total volume of water in aquifers underground is 100 times the amount found on the surface. Across Africa more than 300 million people are said not to have access to safe drinking water. Freshwater rivers and lakes are subject to seasonal floods and droughts that can limit their availability for people and for agriculture. At present only 5% of arable land is irrigated."
More resources means people will think they can make more people. Which, of course, will be worse in the long run since underground water never lasts forever, and it will be a larger population to starve.
What Africa needs is education, not more water to be exported to other countries.
It is also a FINITE supply.... not a true fix for water shortage problem long-term...

I don't care how much good that water might do today: I want to know how long it'll last if a billion people start sucking it up. Aquifers replenish, but only very slowly. Even the scientists behind the research are stressing that industrial-scale drilling will exaust the supply eventually.
Global warming is likely to lead to a de-desertification of Africa anyway, as increasing equatorial heat increases the absorption of water by the air over the Atlantic. But it's still Africa.
Help stamp out iliturcy.
I think the opposite is true. Infant mortality is high in these areas so they have more children in the hope some survive. When there is food, medicine, better sanitation etc, they breed less because there is less chance of the infants dying.

You see this bullshit all the time from people who never took more than BIO 100 and presume that humans work like bacteria. Turns out, they don't. The proof of that is first world nations. They all have at most low population growth, and many have neutral or negative population growth. The "human bacteria" theory says they should be the prime places for a massive booming population. There's abundance in everything and IMR is low so population should explode... But it doesn't.
Turns out when you solve the basic needs, when people have more than a subsistence living, when they don't have to worry about a bunch of their offspring dying, they stop having so many kids.
The way to control population is not to try and starve people of resources. You might notice that is the situation now and yet there's high birth rate. The way to control is to get people better lives. Sufficient food, clean water, medical care, shelter, etc and then the population growth is tamed.
This isn't a "Well we hope humans work like this," theory, it is how things HAVE worked. It is the reason there was no massive boom and crash in the US, Europe, Japan, and so on. Population growth has slowed, leveled off, or even inverted in all the places that have the most abundant resources.
The strategy of "Just let the brown people die," is not only extremely callous, it is also counter productive to getting a stable population level.
Exactly. When you pump water out of the ground it's gone forever.
Underground reservoirs are not necessarily refilled by the next rain. Read up on such reservoirs found in North America. They were filled over many thousands of years and significantly drained by agriculture related drilling and pumping in decades. Every year agriculture has to drill deeper and deeper to find water.
It gets consumed, evaporates, and then it never rains again.
Of course it rains, the problem is that it does not necessarily rain where the water was harvested. Harvesting deep water reservoirs does not somehow change the fact that a region is a desert or arid region with little rainfall.
