Water Shortage and Desalination Plants -5

Then there is the dry African continent where unsafe water kills millions of people every year due to various water borne diseases. The population there is also growing fast as compared to whatever water they receive from nature. I can keep on going on forever regarding the water problem, but what is the solution here. As the population grows, so does the need for water. But as attractive as conservation looks in the world, the dwindling supply of water has to be met from somewhere and this is where desalination plants come in. Although it is expensive but it is doable but only in rich countries unless costs come down considerably so it can be used in developing countries also.

But desalination plants can only be used in places where it borders with sea, the inland countries and places will still be water deficient. The inland areas may have to import water from coastal areas at cost, which they may not be able to afford. So in that case, the water abundant areas will have to subsidize the water deficient areas which may lead to more inefficiency on the part of inland areas. So again the question begs: How to solve this water shortage problem. Right now, nothing comes to my mind that can be a world wide solution to water shortage except that every country would have to either work on their own for this or they will have to form regional alliance to share their water resources and barter water like they did in the old days. Or may a world centralized body should be in place which can store huge amounts of water in some neutral place and release it to places where it needed most. But again politics will come into play like who is going to administer and have influence on such a thorny matter. So right now there is no absolute solution.
