Norcross, GA — The Ministry of Water Resources of the People’s Republic of China recently announced a project that uses ERDAS IMAGINE to facilitate conserving and protecting China’s water resources. ERDAS IMAGINE is being used to identify the areas where the water is being adversely affected by soil erosion. Beijing Digital LandView Company Limited, the authorized ERDAS ...
Solve Challenging Slope-Surface Stability Problems Stabilize cut slopes from mining operations and roadway embankments using the long-lasting GEOWEB geocell solution. The GEOWEB 3D structure allows slopes to be constructed at steeper angles (>45º) while solving soil erosion and slope-surface stability problems, potentially with waste rock infill. GEOWEB geocell ...
The U.S. Environmental Protection Agency today announced the award of 14 Great Lakes Restoration Initiative grants totaling over $17 million to fund projects that will improve Great Lakes water quality by preventing phosphorus runoff and soil erosion that contribute to algal blooms and by reducing suspended sediments in Great Lakes tributaries. “These Great Lakes Restoration Initiative ...
How best to integrate the ecosystem services concept into regional planning? A recent study provides a practical example for an area in Germany that is faced with an increased risk of soil erosion under climate change. Researchers used a decision-support system incorporating ecosystem services to show that measures to reduce soil losses could also support a number of other services. Ecosystems ...
Grassed waterways are placed in agricultural fields where runoff water tends to concentrate because they can substantially reduce soil erosion. Mapping techniques that help identify where erosion channels will likely form could help farmers and conservation professionals do a better job of designing and locating grassed waterways in agricultural fields. Tom Mueller, associate professor in the ...
Soil erosion of croplands, rangelands, and urban areas is one of the most common problems that negatively affects the environment. Soil particles carried by rainwater along slopes may transport a variety of harmful agricultural and industrial chemicals, cause the soil to lose fertility, and inundate streams. Quantifying the movement of soil through watersheds is a complex task, which requires ...
Millions of people worldwide will today participate in the annual STAND UP and TAKE ACTION against Poverty and for the Millennium Development Goals (MDGs) event to demand that world leaders keep their promises to end poverty and inequality. The United Nations Environment Programme (UNEP)'s message on this day is simple: investing in environmental management that benefits the poor will deliver ...
Soil erosion is an important issue in Europe, with consequences for water quality, ecosystem services supply and crop production. In this study, researchers enhanced an existing model to estimate soil loss and create an updated map of soil erosion across the EU. The authors say the tool can simulate the effects of land use changes and management practices and will support effective policy ...
Rainfall is one of the principle causes of soil erosion. It breaks apart soil, dislodges it from its surroundings, and washes it away as runoff. These mechanisms have an effect on how much water the soil may hold, how fast water flows over the soil, and even on the soil depth. In a much broader sense soil erosion can negatively affect vegetation growth and yields, as well as water quality, and ...
Soil erosion has been divided traditionally into sheet, rill, and gully erosion. In rills and gullies, overland flow is concentrated, which markedly increases the erosivity of the flow, and can cause then significant incisions into the landscape. Usually rills occur on sloping surfaces, whereas gullies occur within swales or hollows. Concentrated flow erosion represents an important -if not the ...
A draft budget approved by the Italian government last Friday contains 'ten pieces of good news' for the environment, according to environment minister Alfonso Pecoraro Scanio. Kyoto protocol compliance measures will attract €600m, while €150m will fund 1,000 new green spaces in Italy’s congested cities. Soil erosion measures will claim €530m, and some €130m is earmarked for boosting rail and sea ...
A midnight landslide at a mining community in central China buried several dormitories and homes, leaving more than 60 people missing, local authorities said Wednesday. The provincial government of Shaanxi said 15 dormitories belonging to the Wuzhou Mining Co. were buried along with three homes in the mountainous county of Shanyang, and that 14 people had been rescued. It said authorities have ...
Embankments and slopes are highly susceptible to soil erosion. Given the fact that they can cause really serious damage to life and property, one cannot help but rely only on high quality erosion control products. This is where Soil Stabilization Innovations (SSI) comes into the picture. Since its inception more than 20 years ago, SSI has been delivering world leading services with their in-house ...
Over 8% of land in Europe could be at moderate-to-high risk of wind-driven soil erosion, a new study has estimated. In the first assessment of its kind, the researchers produced maps which show wind erosion risk across 36 countries. This information could help guide actions to tackle land degradation. Soil erosion by wind is, to a certain extent, a natural process that has always played a role ...
U.S. Environmental Protection Agency Region 5 has issued a consent agreement and final order to Oregon Holdings IV LLC for filling in about 6.3 acres of wetlands at its development site, 750 Lallendorf Road, Oregon, Ohio, without a permit. The company has agreed to pay a $75,000 penalty. EPA alleged that in May and June of 2004 Oregon Holdings filled in wetlands adjacent to Johlin Ditch while ...
Cranfield University has signed an important Memorandum of Understanding with Omar Al-Mukhtar University in Libya, for the development of education and research links in natural resource management. Desertification and accelerated soil erosion, limited natural fresh water resources and deforestation are some of the most pressing environmental issues facing the Northern African country of Libya. ...
A set of guidelines has been developed to reduce soil erosion by planting vegetation in desertification hotspots.Farmers and policymakers can use the guidelines to identify the most suitable places to plant vegetation in the channels where water and sediment move through the landscape. Land degradation through desertification typically occurs in vulnerable, semi-dry areas. As a result of ...
Over the years local residents of Rebero in Gicumbi District north of the Rwandan capital of Kigali, watched as their soil was washed away by rain. They also had to contend with landslides. Until a local group, the Rebero Emergency Response and Mitigation (ERDM) committee, started to reclaim the land in 2004, mainly through terracing. 'After being trained in risk management we came up with a ...

The Department will issue a time and material type contract with a three year period of performance and a not-to-exceed value of $2,249,264. Work performed under this contract will be performed at the contractor’s facilities and at the Los Alamos National Lab in Los ...
Haiti, one of the poorest and most environmentally degraded countries in the western hemisphere, is one of the many examples in recent times of the crucial role played by ecosystems in reducing disaster risk. Prior to the earthquake in January 2010 which devastated the country, environmental degradation was already a critical challenge, as extensively degraded catchments made Haiti's rural and ...
