1st Prize (Tie)—Anticipating the eventual exhaustion of the essential resource of water along the U.S.-Mexico border, an “irrigation wall” would draw water from the Gulf of Mexico, the Sea of Cortez and the Pacific Ocean, desalinate it and flow it into a channel running the length of border. Possible benefits could include re-vegetation of the desert, creation of agricultural operations on either side of the channel and new bilateral treaty governing the distribution and use of the water between the two countries.
