Climate change is now threatening France's Aquitaine coast, which stretches north from the Spanish border to the Gironde River, causing erosion that is endangering coastal communities. In 2006 the European LIFE program identified 13 coastal communities as hotspots for erosion. "There is a lack of sand on the beaches, because of a period of warming -- climate change," says Cyril Mallet, of the French geology and mining research agency BRGM. Climate change means more erosion for the area,...

A U.S. study shows rivers in some of the world's most populous regions are losing water, with some losses attributed to climate change. The study by the National Center for Atmospheric Research suggests the reduced stream flow potentially threatens future supplies of food and water. The scientists, examining stream flow from 1948 to 2004, said they found significant downward changes in about one-third of the world's largest rivers, including the Yellow River in northern China, the Ganges in...

Climate change is resulting in massive drying of some of the world's biggest rivers, according to a report released on Tuesday. Researchers led by Aiguo Dai of the National Center for Atmospheric Research (NCAR) in Boulder, Colorado found that rivers including the Yellow River in northern China, the Ganges in India, the Niger in West Africa, and the Colorado in the southwestern United States are in danger of losing water due to climate change. "Reduced runoff is increasing the pressure on...

Researchers say coastal erosion along a 40-mile stretch of the Beaufort Sea in Alaska more than doubled to about 45 feet annually between 2002 and 2007. U.S. Geological Survey scientist Benjamin Jones, who led the study, said although the patterns documented in the research might represent a short-term episode of enhanced erosion, the findings might also represent the future pattern of coastline erosion in the Arctic. Jones and his colleagues said recent shifts in the rate and pattern of land...

Pebbles that become part of clastic rocks in places like Arizona's Lower Antelope Canyon don't move with the wind but against it, a geosciences professor said. Rather than being pushed into formations, the pebbles, or clasts, have the loose sand around them removed by the wind, Andrew Leier of the University of Calgary said in the journal Geology. The sand removal causes scour-pits to form on the wind side of larger clasts, and the pebbles eventually fall toward the wind into the scours, he...

Marginal plants, particularly trees, play a crucial role in sustaining the biodiversity of Europe's big river systems, according to a recently held workshop organized by the European Science Foundation (ESF). This finding provides important clues for protecting Europe's rivers against a combined onslaught from human development and climate change, which are tampering with existing ecosystems and changing both the physical and biological forces acting upon them. Both aquatic plants (living in...

A new study on Wednesday warned that climate change is the cause of rising sea levels that will erode Sydney's iconic beaches by 2050. The NSW Department of Climate Change study said some are at risk of disappearing and threatening beachfront homes and commercial properties. The Sydney climate change impact report detailed how sea levels along Sydney's coast are expected to rise by up to 40 cm above 1990 levels by 2050 and by 90 cm by 2100, with each one centimeter of rise resulting in one...

By Tony Henderson RECENT flooding has been part of the price for the way the landscape has been changed in the past, a North river scientist has said. "We are paying the price for not thinking about how our management of the land impacts negatively on the water environment," said Professor Stuart Lane, executive director of the Institute of Hazard and Risk at Durham University. Prof Lane said past measures, such as digging drainage grips in upland moors, had caused major problems....

By Wes Woods II CLAREMONT - Community services director Scott Carroll on Tuesday night admitted responsibility for the bulldozing of the Claremont Hills Wilderness Park. "If you want to find out who's responsible for doing this, it's me," Carroll told a crowd of 35 to 40 people inside the Oak Room at the Joslyn Senior Center on Mountain Avenue. After Carroll displayed a PowerPoint presentation about the 100- to 120-foot-wide clearing on the eastern edge of the park, audience members...

Desert greening
2013-04-25 16:10:03

Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...

Theodore Roosevelt National Park
2013-04-18 01:20:13

Theodore Roosevelt National Park is located in western North Dakota in the United States. The park contains 70,446 acres of land that is separated into three distinct badland areas known as the Elkhorn Ranch Unit, the South Unit, and the North Unit. Roosevelt  first visited the area in 1883, while hunting for bison, and is said to have “fallen in love” with the badlands. After investing a large sum of money into the Maltese Cross Ranch, Roosevelt had his own cabin built, which he later...

Badlands national Park is located in the southwest region of South Dakota. It holds 242,756 acres of land, with 64,144 acres comprising a protected wilderness area. The park was designated as a national monument in 1929 and established in 1939, but attained national park status in 1978. The Stronghold Unit area of the park is managed by the National Park Service and the Oglala Lakota tribe and holds many sights including those used for Ghost Dances in the 1890’s, a bomb and gunnery range...

A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....
