No water for Pakistan from glaciers after 2060: UNDP

[RescueRanger]

desalination isnt as easy as you think, some things to consider -

1) Amount of waste is just huge, just the amount of salt back from the process will be in the thousands of tons every year, where will you dump all this without causing a natural disaster ?

2) Marine life is damaged heavily has they are pulled into the pumps and end up getting chopped up in the turbines. This was a huge concern in the US when they were making their first desalination plant.

3) Cost - simple and easy, it cost a lot lol Water will get much more expensive

4) Output - desalination plants does not really generate that much water and cannot sustain a city by any means. Would need atleast 5-6 of these to sustain a city like Karachi.

there are some other variables also, so until the tech is not perfected, this will be a tough road to take.

I am no expert on such matters and nor do i pretend to be. But i know that some action is better than inaction. And if it ain't broken....

1) Back into the seas from where it was taken in the first place.

2) No they don't..

3)Yes..it is expensive as the technology is not developed enough. Once more people start using it,it will become cheaper like every other tech out there

4) You need electricity to run these plants...nuclear power is the best for it.And sea water is abundant so it will not get over.

I believe India has an experimental nuclear desalination plant somewhere in the South but I read that people don't use that water as they are afraid that it is radioactive!!

Both India and Pakistan need a lot more of these as Eastern India,Pakistan and Bangladesh are in for bad times otherwise.

By 2060, I am sure our technology will have advanced far enough as to easily provide water to all of Pakistan and India.

As for the growth rate, by 2060 Pakistan will have 99% literacy and would probably be a 1st world country if we fix our government soon enough.

actually you cannot dump that much salt back in the sea, salt will sink and mix into the water instantly and if you research how salt moves through the ocean, it will show you how salt moves very slowly and warms up all the water around it. Extra salt will also kill of vegetation and many fishes and will have many long terms effects.

don't worry desiman

We still have 50 years left to tackle with these crisis. Look at the other countries for an instance. Take an example of Saudi Arabia, they are money rich but not technology rich and the whole of Saudi Arabia is relying upon the desalination plants. I am sure sooner of later we will start doing the same

If Saudi Arabia has found the solution of this problem i am sure we have plenty of years to find similar solutions

i hope so, there are many advancements being made in this tech, hope it manages to solve this very grave problem that south asia will face in the coming years.

You don't dump it at once..you do it slowly.

Desalination plants are up and running in many places successfully.

i realized one thing. Even after desalination the water does not become sweet as the water of glaciers and significant amount of salt still remains in the water. In Saudi Arabia they use this desalination water for cleaning clothes, vessels and non-drinking purposes only. For drinking they use Mineral water and Aab-e-Zam Zam, The holy water. It is still drinkable but not as sweet as the water of glaciers.

It would be sad to see if we are left with no other option but relying upon the desalination plants only

Not really a big issue because drinking water typically represents a very very small percentage of overall water use. You can always rely on springs, ground water, harvested rain water etc. for drinking purposes.

That is only possible of BP and some countries don't pollute all the sea with deep water drilling they can't shut down ..... we won't even have water in sea left if that is the case just oil
