in response to atlanta's worsening drought, a reworking of something I wrote

Water Pipeline, solar energy, water desalinization and desert farming

By no means is water desalinization a cheap way of producing clean drinkable water but it has to be seriously considered and transporting the water in the quantities needed also has to be addressed when it comes to bringing clean drinkable water to people who need it, in an attempt to get around the geographical barriers like mountain ranges such as the Rocky Mountains of North America, and the mountain range that goes down the western side of the African continent that has made much of the African continent that acts like a barrier keeping the clouds from moving into the arid areas which are growing in size at least in Africa, I hope this is a workable idea that could be used but the people that have the capability to get it done.

In areas that are desert terrain due to mountain ranges being too tall to permit rain clouds to move past them, build water pipelines that travel over and through the mountain ranges to large desalinization plants in the deserts.
Power the desalinization plants using the technology currently being used in the solar one project (thermo-trough solar arrays) or another large scale solar power array so as not to use any type of fossil fuels.
Each desalinization plant would need to be large enough to exceed the needs of the population of the desert communities that they would be serving them to account for the water loss due to the excess heat of the desert.
In an attempt to contain the water and to provide climate controlled farming for these desert communities, build greenhouses that are based on the bio-dome concept, while compensating for the excess carbon dioxide that is more than the plants can handle in the self contained environment, install a bioreactor based on the design tested by MIT for GreenFuel Technologies Inc. which uses algae to collect carbon dioxide.
When deciding what to farm in the bio-dome style greenhouses, for crops grow food that the communities traditionally eat and would be willing to eat along with breeding what they traditionally call farm animals that have the ability to roam anywhere in the facility that is used for growing plants except for where the crops for the communities are grown.
Utilizing some of the extra desalinized water and extra growing space, provide greenhouse services for the communities specializing in plants, bushes and trees indigenous to the specific region with a section geared towards the rare foliage in an attempt to keep the plant, bush or tree species going.
When designing the system as a whole, design it to permit a minimum or maximum amount of water loss and design it to be a water dispensary so that a predetermined amount of water can be distributed to other areas in the desert communities and to create and maintain periodic placements of water facilities for travelers.
Any brine that is unusable either pipe it back into the ocean if it has little to no negative impact on the regions it is being placed into even if it means dispersing it over a wide area, or allow it to dry out to provide sea salt to those who use sea salt.
