Facing an unprecedented water crisis, Israel is speeding up plans to desalinate even larger amounts of seawater than it had already planned. The National Infrastructure and Finance Ministries say in early January they will issue a build-operate-transfer tender for the largest reverse osmosis desalination plant in the world, to be built 40 kilometers south of Tel Aviv. In an effort to speed up the construction of other badly needed plants, the Israeli government has also decided to exempt state utility Mekorot Water from the usual tender process for its planned 100 mcm desalination plant at Ashdod. The government has also
Shifting the emphasis of flood risk reduction work from structural, to non-structural efforts, such as better risk communications and improved evacuation planning, is a key recommendation the National Committee on Levee Safety will make in a report to Congress on Jan. 15.

The levee failures in New Orleans after Hurricane Katrina sounded a national alarm on the unreliability of levees for flood protection, the committee concludes. It will recommend greater use of evacuations during periods

Before the end of the year, the first in-stream hydrokinetic turbine to produce commercial power will be installed in the upper Mississippi River — just days after receiving the a first of its kind approval from the Federal Energy Regulatory Commission for the device. Hydro Green Energy LLC of Houston will place its 12-feet in diameter turbine about 50 feet downriver from the Army Corp of Engineers Mississippi Lock and Dam No. 2 in Hastings, Minn.

After two days of public hearings and debate, the South Florida Water Management District’s governing board still hesitated to approve an agreement to purchase 180,000 acres of land in the Everglades Agricultural Area from the United States Sugar Corp. for $1.34 billion. As it stood, the board feared, the agreement could expose the district to penalties for conditions over which it had no control. Finally, the board approved a modified agreement with a 4-3 vote, knowing that the Clewiston, Fla., agribusiness might refuse to accept the amendment. But late on Dec. 16, after the water district’s vote, U.S. Sugar issued

Ralph Grossi, the immediate past president of the American Farmland Trust, says Salazar did “yeoman’s work” in
A federal appeals court’s decision has taken a step toward lifting a state ban on out-of-state water sales, opening a way for a proposed $3-billion project to pipe water from Oklahoma to Texas. The appeals court accepted a north Texas water district’s argument that Oklahoma’s ban could constitute illegal restraint of interstate commerce.
