• Pollution a major problem
  Some of these pollutants also come from natural sources. For example, forest fires emit particulates and VOCs into the atmosphere. Ultrafine dust particles, dislodged by soil erosion when water and weather loosen layers of soil, increase airborne particulate levels. Volcanoes spew out sulfur dioxide and large amounts of pulverized lava rock known as volcanic ash. A big volcanic eruption can darken the sky over a wide region and affect the Earth’s entire atmosphere. The 1991 eruption of Mount Pinatubo in the Philippines, for example, dumped enough volcanic ash into the upper atmosphere to lower global temperatures for the next two years. Unlike pollutants from human activity, however, naturally occurring pollutants tend to remain in the atmosphere for a short time and do not lead to permanent atmospheric change.

• Hydel project protects eco-system of Yellow River
  ZHENGZHOU, Henan: The 35.2-billion-yuan Xiaolangdi Water-Control Project on the Yellow River in Henan province is helping to improve the eco-system and environment downstream, officials said yesterday.
  The scheme, supposedly the largest on the river, was started in 1994 to manage levels at more than 92 percent of the river's basin areas, 90 percent of its water flow and its total sediment downstream.

• Side-Hill Retaining Walls: An Overview and Alternatives (Part 2 of 2)
  We have looked at some of the general issues and problems with side-hill walls, covered what types of investigations may be needed, and looked at the tools to be used for analysis. Now we will discuss various wall types and alternatives to walls that can be used for side-hill applications. We will briefly describe each option and hit some of the significant pluses and minuses for their use. The various alternatives I will be discussing are given in the following list.

• Feds, tribes work to cut silting in Missouri River
  FORT PIERRE, S.D. (AP) – Erosion and a buildup of silt are hurting water quality, recreation, hydropower generation, flood control and nearly every other beneficial use of the Missouri River in South Dakota, members of a new task force said Thursday.
  The Missouri River Task Force for South Dakota held its first meeting to begin work on plans for protecting the river from erosion and the sediment that flows in from tributary rivers and streams.

• Arctic meltdown is a threat to humanity
  I AM shocked, truly shocked," says Katey Walter, an ecologist at the University of Alaska in Fairbanks. quot;I was in Siberia a few weeks ago, and I am now just back in from the field in Alaska. The permafrost is melting fast all over the Arctic, lakes are forming everywhere and methane is bubbling up out of them." The permafrost is melting fast all over the Arctic, lakes are forming everywhere and methane is bubbling out of them
  Back in 2006, in a paper in Nature, Walter warned that as the permafrost in Siberia melted, growing methane emissions could accelerate climate change. But even she was not expecting such a rapid change. "Lakes in Siberia are five times bigger than when I measured them in 2006. It's unprecedented. This is a global event now, and the inertia for more permafrost melt is increasing."

• Impact of floods on soils
  A recent study conducted in the Midwestern United States examined the effects of harsh wet conditions on both cultivated and uncultivated soils, vastly advancing the knowledge of water’s effects on aggregation. Soil aggregation is an important soil attribute that is related to the physical-chemical state of the soil, and is one of the essential processes that determine soil quality. During the wet season in the U.S. Midwest, upland soils are often under water for days or weeks, causing oxygen depletion, or reducing conditions, which may in turn affect the chemistry of the soil-water system and, consequently, soil aggregation. Loss of soil aggregation impacts agriculture by decreasing soil quality and crop production.

• First accurate test for arsenic in soil developed
  If you have a cat or dog who likes to hide under the deck or children who play on equipment made with pressure-treated wood, you’ll be glad to hear that analytical chemist Julian Tyson and colleagues at the University of Massachusetts Amherst recently developed the first-ever accurate test for arsenic compounds in soil, promising a significantly improved environmental and health impact assessment.

• New study shows coastal erosion only getting worse
  ANCHORAGE, Alaska -- Erosion has plagued villages in Alaska for many years, and a new study finds the situation is only getting worse.
  The Alaska Baseline Erosion Assessment contains some alarming information about erosion and its impacts -- more villages are losing land than ever before.
  The purpose of the study was to help develop strategies and plans for addressing erosion issues, but with recent changes in the omnibus law, there are concerns about funding to help these villages.
  "When the tide goes down you can see how much erosion we're losing," said Lorien Prince, a member of the Kotlik City Council

• We must protect communities who face climate change displacement
  n Alaska, climate change is creating an unforeseen humanitarian crisis. Arctic sea ice – which had protected communities from coastal erosion and flooding – is rapidly disappearing and signalling a radical transformation of this northern ecosystem. Scientific observations during the summer of 2007 documented a new record low.
