3. Studying Desert Ecosystems

   

2005

8 March 2005. For Iraq's Great Marshes, a Hesitant Comeback. By JAMES GLANZ for The New York Times. Excerpt: ABU SUBAT, Iraq, March 1 - ....A dike that Saddam Hussein's government finished nine years ago had drained this marsh, once part of an incomparable ecosystem spread across 7,000 square miles of southern Iraq that Mr. Hussein systematically destroyed. After sealing this dike, the government gave families 24 hours to leave and never come back, Mr. Hashim said. The ruined houses were left sitting on dusty little hills in a barren and bone-dry desert.... But when Mr. Hussein's government fell in April 2003, villagers went to the dike and gouged holes in it using shovels, their bare hands and at least one piece of heavy equipment, a floating backhoe. Since then, something miraculous has occurred: reeds and cattails have sprouted up again; fish, snails and shrimp have returned to the waters; egrets and storks perch on the jagged remains of the walls, coolly surveying the territory as if they had never left.... Mr. Hussein's obsessive and vindictive drainage program, in fact, was intended to obliterate this prime refuge for deserters from his army and the southern Shiite guerrillas, many of them marsh Arabs who fought his government long before the Americans arrived.... The scientists reported that less than 10 percent of the original marshes still function as true wetlands, but that about 20 percent of the original area had been reflooded by March 2004, according to satellite imagery. High salt content in soil and water, threatens the recovery of the marshes in certain areas, the paper said. As Dr. Hussain's team pulled up muck and spinachlike aquatic plants from the bottom of this marsh for testing, he confirmed the problems and said the thickets of reeds in this marsh were still only about half as dense as they had been before the marsh dried up. Some plants, like water lilies, had not come back at all, he said.

13 December 2002. From Wetland to Wasteland. Due to drought and over irrigation, the once fertile Hamoun wetlands on the Iran-Afghan border have all but disappeared. Using remote sensing satellites developed by NASA, researchers with the United Nations Environmental Program are cataloguing the extent of the wetlands degradation and exploring ways to restore them.
