Counterproductive environmental measures

[Obamot]

No it's not a joke!

80 cm wide in penthouse in “pallet frames” (to isolate concrete on a blown clay bed), earth, earthworms urine and it grows (no other inputs, just the job mycelium)

and therefore how many m2 / person it takes with this system to feed them completely?

I am for 100% food sovereignty, so it will be 100% of the possible

8m x 85cm x the height of 2m (hanging gardens), that makes us vegetables from spring to all summer, until autumn ...
We do permanent rotations and it does not run out (we do not always put the salads in the same place)

Another question that calls for no answer, this kind of system does not aim to free itself from any other source of food but in addition to existing ones.

There you have it, that's the reasoning. And how this land got there. And how much time or money did it take to make the bins, or use the jars.

Once again, it's great to do some recycling and use a little bit of the space we have to produce vegetables or fruits. no one says otherwise.

It seems to me difficult to envisage that these cultivation methods be transposed to large populations.

Well yes, since the basic discussion is "to make a city autonomous in its food production", not "can you grow things personally on your balcony"

And Babylon? Doesn't that remind you of anything?

No, again, the scale will depend on political decisions to get there!
The feasibility is ok.

This is all happening, it's a matter of time. Cities now and in the future, that will be!

You don't have to be out of polytechnic to understand that it's totally impossible if you consider the existing cities. Just think of the infrastructure and buildings of mega-cities to realize this (extreme example). On the other hand, where it would become feasible, it is from the design and the realization of new cities, entirely turned towards this objective. We could also add to nutritional independence, energy independence, even excess.

Yes. I agree. We did not understand each other well then.

That said, if the towns are small enough, we will not have to try to cultivate on the roofs (which is an additional constraint), we will be able to be satisfied with the land available in / around the said town. What we did before, and what we will strive for in the future.

Indeed, but on the one hand it will be necessary to convert the 99% of the current habitat (people will continue to live in cities already built, whether we like it or not) ... and that's without counting the fact that the earth is a good thermal insulator 100% recyclable.

energy independence, even excess.

only in summer or when there is wind anyway.

Photovoltaics work in northern Germany even in cloudy weather ....

But not at night

We really need your “scientific” reasoning ...

But what would we do if you weren't there?

to function is one thing. To be in excess of needs is another ...

The other problem is to avoid melting your network when the going gets tough.
