Most likely they would like to be more self-sufficient when it comes to food not coming straight out of a camel. What I wonder is why they use these above-ground rolling sprinklers instead of making a proper dripping system next to or slightly below the ground. That would use a lot less water and thus be much more environmentally healthy as well as more economical.

The water they pump out from those caverns is vaporized into the air and yes, it will eventually fall down on some far away land and maybe end up in the sea. Only one thing is sure, the water they pump out will not get back to those caverns any time soon.

A drip irrigation system like that would be much less efficient than those pivot systems. Much more surface area for evaporation compared to the more intensive methods. They're doing the best with what they have, pretty much.

They have like less than 10 rain days a year and maybe one flood every decade or so. If their ground water runs out they're fucked - unless we found an easy way to transfer salt water into fresh water or have unlimited power to use current systems. Either way its gambling with their (and our) future.

Well I think you need a lot of water to supply your goods. That would mean you have a lot of unwanted stuff in salt water (like salt) which you need to filter. It might work but you'd had to change the
filters every day I think.

Lets research:

>Tomato - 1 kg - 214 liter water
>This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts.

That means 1 kilo of tomatoes would cause nearly 7.5 kilo of salt you need to filter out of the water. I think its close to impossible to achieve that. You need some modern systems to filter the salt out and that costs a lot of power which makes your products way more expensive than imported products from Europe, Asia or the US.

The point is still there. You need to get a lot of salt out of the water and just by air vaporizing salt water you cant do that - I think. Just imagine how those filters would look like after few days...

It does get refilled every year, but not by much. Aquifers are a national treasure and need to be maintained. Once you drain too much water the water quality drops significantly. There must always be a certain level of water inside the aquifer. But people can get greedy, or desperate, and overuse it.

Agricultural lobby is still strong in France.
Maintaining a good agricultural sector here is a price most of our politicians and the population too I believe is willing to pay plus if shit hits the fan relying on countries thousands of kilometres away to produce your food would be really unwise.
Agriculture in France is seen as a strategical sector which we must save at all costs, it's economically retarded short term wise but in the long run it makes sense.

Only if in the long term you actually do need to depend on home grown products.

However, if you look at it as insurance I guess that makes it worthwhile.

You are probably thinking of the New Valley Project, which aims to build a 300 km long irrigation canal snaking northwards from the Toshka Lakes. The canal is about 80% done.
They're trying to open up the valley for agriculture, not build a megacity. From what photos I have seen there's not a lot of agriculture yet, but at least they got plenty of fish in the Toshka Lakes.

>>30660725
That would be a true megaproject. More large-scale vegetation cover would change wind patterns, bringing more rain to the desert.

>>30660826
Graphene filters seem like a promising avenue of research. Because they are so thin there is little energy wasted on forcing water through them. Basically just the power necessary for the pumps, and pumping water is something we do on industrial scales. Where applicable gravity is enough, but you need a gradient for that. Maybe a future opportunity for Egypt to turn the Quattara Depression into a sweet water lake along with a hydro power plants where the tunnels breach the ridge separating the depression from the Mediterranean.

that will never happen, water is cheap.

and underground aqueducts are much cheaper than oil pipelines because of increased volume, and much less concern about leaks (pipe line bursts you lose half a day worth of water production, instead of causing a ecological disaster)

the actual cost of desalinated water is about 8-10 times that of recycled water in cities for reverse osmosis.

for arabs it would probably cost about $500 for 1km^3 of fresh water. they could switch to desalination and grow their own crops if they needed, but it's not really economical at the moment.
