There is enough water on earth, you have to spread it

[jean_db]

No matter how much we talk about it, no matter how much we repair the effects of its too much or too little, we may even make it drinkable, we may sell it, it won't be enough.

Braking and distributing water reduces energy requirements.
It also means being able to produce hydroelectric energy throughout the country, even on windless days and sunless nights.

Encourage infiltration rather than runoff to compensate for the perverse effects of human activities which do the opposite, but also allow water to be the spearhead of the development of life in harmony with the environment.

The distribution of water can control climates, while if the climate is allowed to disrupt the water cycle, climatic disasters will worsen.

Yep ...
Properly distributing water, if only on a European scale, it would be a gigantic project likely to cause the upheaval of many biotopes.

We know the main principles of a more rational use of this resource, but have we drawn all the conclusions concerning the errors made since a few decades in hydraulic installations ?! Ex: Canalization of certain watercourses and new installations intended to counter floods ...

Not sure!

We anticipate well enough the meaux to which we are exposed in the future, and know remedies to lessen the effects, but are we ready to make the sacrifices necessary for better uses and distribution of the resource ?!

Hello
We know that here the northern countries have a surplus of water and the southern countries it lacks water, it is not the amount of water that bothers us here but the acid rain and the pollution that comes to us from the south , when the wind comes from the far north it's not the same air ..
when the americans run out of water it will not bother them to divert the great lakes even if the St. Lawrence river drops from year to year (it is the outlet of Niagara falls)

If the Nordic countries have so much water it is mainly due to the fact that the Northern Lakes are frozen for 6 months there is very little evaporation and snowfall there can fall a total of 2 a 3 meters, with the cast iron, the earth and frozen there is little infiltration, so a lot of water to evacuate in spring, in May. But with the shortening of the winters and the heating it risks changing in the future...
Distributing the water will be complicated and will require major works, but the important thing is to keep the water clean.
There is a certain village that the water requires very little treatment, it is limited to a control, it pumps directly into a lake, also on these lakes it is forbidden to circulate with motor vehicles, boat, snowmobile or plane to land there ..
In general if there is much gray trout the water is of quality!
Lakes further south begin to be polluted by blue algae
which makes the water unfit for consumption.

You said:

"Distributing the water will be complicated and will require major works"

By pitiè do not repeat the same mistakes ...
Distributing the water with the help of major works to return to concrete channels and ultimately sell it to those who can pay it and exclude others, this is not the principle of the overall management of the resource in water.

Why?

To answer this, we must already understand that the current situation on water comes from the commercial management of water, the perverse effects of which on the environment go in the direction of soil drying, which also has other factors. dewatering.

For example, just because we are going to apply drip irrigation does not mean that we will not overexploit underground reserves and advance deserts beyond irrigated areas.

We must therefore put the subject first on the table of international debates in order to raise awareness of the impact of the drying up of subsoils by overexploitation of groundwater on climates.

Then set up a global water distribution program by watershed capable of re-infiltrating excess runoff.

Indeed, it would be useless to do large water transfer projects here or there on the planet if everywhere else we continued to do the opposite.
