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...

With recent increase in the cost of energy and subsequent explorations into alternative energy sources, the increased harvest of corn residue for cellulosic ethanol production is likely in the future. This may be especially true in fields where corn is grown continuously, in part because perennially high residue amounts favor annual harvests, and also because corn residue left on the soil surface is a source of inoculum for corn diseases. Removal of corn residue, however, may require changes...

Hurricane Ike reconfirmed one Texas researcher's idea: Interfering with Galveston Island's natural elevation hurts the island's sand dunes and marsh flora. Ike reconfirmed the basic idea I've had for several years, Rusty Feagin, ecosystem scientist with Texas AgriLife Research at Texas A&M University, said in a news release. The plants on sand dunes and in marshes build an island's elevation, so we shouldn't compromise that. When comparing pre- and post-Ike marshes, Feagin said he found...

New research shows that we should be looking to the ground, not the sky, to see where climate change could have its most perilous impact on life on Earth.Scientists at the University of Toronto Scarborough have published research findings in the prestigious journal, Nature Geoscience, that show global warming actually changes the molecular structure of organic matter in soil."Soil contains more than twice the amount of carbon than does the atmosphere, yet, until now, scientists haven't...

A three-year nationwide survey has found that over a third of China's land is being scoured by serious erosion that is putting its crops and water supply at risk. The country's bio-environment security research team said soil is being washed and blown away not only in remote rural areas, but near mines, factories and even cities. Every year, 4.5 billion tons of soil are lost, which threatens the country's ability to feed itself. Harvest in China's northeastern breadbasket could fall 40...

Intense glacial erosion has not only carved the surface of the highest coastal mountain range on earth, the spectacular St. Elias range in Alaska, but has elicited a structural response from deep within the mountain. This interpretation of structural response is based on real-world data now being reported, which supports decades of model simulations of mountain formation and evolution regarding the impact of climate on the distribution of deformation associated with plate tectonics. A team of...

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...

By CHRISTINA ABEL After eight months of waiting, four Vilano Beach oceanfront homeowners whose dwellings are within feet of tall, eroded dunes have permission to build a seawall to protect themselves from further beach erosion. The homeowners have been working with the state Department of Environmental Protection to get approval to build a permanent wall that would stop more sand from slipping away from their homes' foundations. DEP officials had said they would give the homeowners a...

By Denis Cuff The California Coastal Conservancy has given a Martinez-based conservation group the final funding it needs for a $3 million environmental restoration and trail building project on 702 acres of open space in the hills between Hercules and Martinez. The $515,000 grant for work on the Fernandez Ranch was announced Monday by the Muir Heritage Land Trust. The announcement caps a three-year drive by the group to raise enough money from grants and private contributions to repair...

Erosion
2013-04-01 12:48:39

Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...
