MIKE ISLAND, La. \u2014 Erosion, sinking land and sea rise from climate change have killed the Louisiana woods where a 41-year-old Native American chief played as a child. Not far away in the Mississippi River delta system, middle-school students can stand on islands that emerged the year they were born.<\/p>\n

NASA is using high-tech airborne systems along with boats and mud-slogging work on islands for a $15 million, five-year study of these adjacent areas of Louisiana. One is hitched to a river and growing; the other is disconnected and dying.<\/p>\n

Scientists from NASA and a half-dozen universities from Boston to California aim to create computer models that can be used with satellite data to let countries around the world learn which parts of their dwindling deltas can be shored up and which are past hope.<\/p>\n

\u201cIf you have to choose between saving an area and losing another instead of losing everything, you want to know where to put your resources to work to save the livelihood of all the people who live there,\u201d said lead scientist Marc Simard of NASA\u2019s Jet Propulsion Laboratory.<\/p>\n

While oceans rise because of climate change, the\u00a0world\u2019s<\/a>\u00a0river\u00a0deltas<\/a>\u00a0\u2014 home to seafood nurseries<\/a> and more than\u00a0300 million people<\/a>\u00a0\u2014 are\u00a0sinking and shrinking.<\/a><\/p>\n

To figure out where to shore up dying deltas, NASA is\u00a0studying\u00a0<\/a>water flowing in and out of Louisiana\u2019s Atchafalaya and Terrebonne basins, sediment carried by it and plants that can slow the flow, trap sediment and pull carbon from the air.<\/p>\n

Louisiana holds 40 percent of the nation\u2019s wetlands, but they\u2019re\u00a0disappearing fast<\/a>\u00a0\u2014 about 2,000 square miles (5,180 square kilometers) of the state have been lost since the 1930s. That\u2019s\u00a0about 80<\/a> percent\u00a0of the nation\u2019s wetland losses, according to the US Geological Survey.<\/p>\n
