[font size=3]NEW YORK, May 24, 2012 Ben-Gurion University of the Negev (BGU) researchers have created a man-made oasis in the desert with the successful application of a solar-powered desalination system that provides water for irrigation in arid regions. The project was made possible with support from American Associates, Ben-Gurion University of the Negev (AABGU).
The solar-powered system uses nanofiltration membranes to treat the local brackish (saline) water, resulting in high-quality desalinated irrigation water. The results of the Josefowitz Oasis Project indicate that irrigation with desalinated water yields higher productivity from water and inorganic fertilizers compared with current practices. Crops grown with desalinated water required 25 percent less irrigation and fertilizer than brackish water irrigation. In some cases, the yield of crops increased.
The findings were presented in a paper at the Conference on Desalination for the Environment in Barcelona late last month by Dr. Andrea Ghermandi of BGUs Zuckerberg Institute for Water Research (ZIWR) on behalf of his colleagues Drs. Rami Messalem (ZIWR), Rivka Offenbach, and Shabtai Cohen of the Central Arava Research and Development Station. The Josefowitz Oasis Project was funded by Samuel Josefowitz, of Lausanne, Switzerland with additional support from The Alliance for Global Good, Greensboro, North Carolina through AABGU.
The growing global demand for food and competition for resources between economic sectors compel future agricultural systems to be more efficient in the use of natural resources, such as land and water, says Dr. Ghermandi. In the Middle East, the lack of fresh water promotes the exploitation of marginal quality sources such as brackish aquifers, but the sustainability of the current management practices is questionable.

(36,257 posts)1. BGU ?
My first thought was Boy George University ...

They have more motivation to research solar desalination than Boy George University.

(23,671 posts)3. Is this applicable to drinking water, or just irrigation?
It sounds perfect for remote regions with no easy access to water.

(19,233 posts)4. Is this brackish water from shoreline environments, or aquifers?
Because aquifer-derived irrigation eventually runs out, especially in desert regions.

This water is coming from the aquifer

Thank you.

I feel we need to acknowledge that we are in a tough position, and acknowledge that efforts are being made to improve it.
