Excerpts;

Atlantic City, NJ officials, are blocking access to a half-mile stretch of beachfront after erosion created cliffs as high as 18 feet. It will be at least four months until the beaches will be open to the public again.

The Army Corps of Engineers pumped 280,000 cubic yards of sand after Tropical Storm Irene five months ago at a cost of $10.3 million, officials told NBC Philadelphia.

“The problem is when they build these dunes so high, it’s just like building a sand castle on the beach,” he tells KYW Newsradio. “When they are undermined, they cave in and it leaves a tremendous cliff, and the cliff is about 17 feet high — and you don’t see it, especially at night.”

The upcoming fix-up job will pump 1 million cubic yards of sand onto the shoreline throughout the affected area, and another 325,000 in Ventnor. All that sand will cost $14.1 million. If more sand is needed, the cost could bump up to $16.8 million…

Oil Spill Brings Attention to Delicate Gulf Coast

Excerpts;

For decades, farmers and fishermen along the Gulf of Mexico watched as their sensitive ecosystem’s waters slowly got dirtier and islands eroded, all while the country largely ignored the destruction.

It took BP PLC’s well blowing out in the Gulf, and the resulting environmental catastrophe when millions of gallons of oil spewed into the ocean and washed ashore, for the nation to turn its attention to the slow, methodical ruin of an ecosystem vital to the U.S. economy. Last month, more than a year and a half after the spill began, the U.S. Department of Agriculture announced a three-year, $50 million initiative designed to improve water quality along the coast…

Excerpts;

Coastlines, working patterns, and even the country’s most famous meal are under threat from climate change, Britain said Thursday in its first-ever national assessment of the likely risks.

The 2.8 million pound ($4.4 million) study sets out the most pressing problems expected to affect the United Kingdom as a result of climate change, from rising sea levels to more frequent summer droughts.

Beaches and historic coastlines are likely to be reshaped by coastal erosion, with the rate expected to increase fourfold, the report said…

Climate Change Risk Assessment (CCRA) Report, Department of Environment, Food and Rural Affairs
“The Government published the UK Climate Change Risk Assessment (CCRA) on 25 January 2012, the first assessment of its kind for the UK and the first in a 5 year cycle. It sets out the main priorities for adaptation in the UK under 5 key themes identified in the CCRA 2012 Evidence Report – Agriculture and Forestry; Business, industries and Services; Health and Wellbeing; Natural Environment and Buildings and Infrastructure – and describes the policy context, and action already in place to tackle some of the risks in each area. It highlights the constraints of the CCRA analysis and provides advice on how to take account of the uncertainty within the analysis.”

Excerpts;

Coastal storms are known to cause serious damage along the shoreline, but they also cause significant disruption of the deep-sea ecosystem as well, according to a study of extreme coastal storms in the Western Mediterranean published in the Jan. 25 issue of the online journal PLoS ONE.

One-Third of Central Catalan Coast Is Very Vulnerable to Storm Impact, Science Daily
A coast’s capacity to cope with the impact of a storm depends on the intensity of the storm and the geomorphology of each beach. The most common “damaging” processes are flooding and erosion.

Bold Plan Proposed to Save Coastal Louisiana

Excerpts;

A $50 billion, 50-year proposal aspires to stop coastal land loss in Louisiana, build new levee systems to protect cities and even begin to slowly reverse the trend of eroding marsh that has turned the entire southern portion of the state into one of the nation’s most vulnerable regions to sea level rise…

Since the 1930s, the state’s coast has lost about 1,900 square miles, an area larger than Rhode Island. Louisiana’s delta, created by the Mississippi River, has been falling apart because of levees on the Mississippi, oil drilling and other causes…

The Impact Of Ports India
Human interference and construction activity such as port building along the Orissa’s shoreline, have gravely accelerated the rate of beach erosion. An assessment on the Orissa coast, showed long-term shoreline change for a period of 38 years from 1972-2010. Thirty seven percent of the state’s 480km coastline is exposed to sea erosion.

Haiti’s Unnatural Floods

Uploaded by mrtimetree on Youtube.

The nearly complete deforestation of Haiti has caused countless problems for the country, the people, and its biodiversity.

One such problem is examined in this video: the effect on stream flow. It is shown that many floods and droughts in Haiti are caused by deforestation, because forests help retain rain water.

haiti erosion deforestation
Rising waters. In the passed decade or so, Haiti had undergone a major deforestation because of the production of coal. The lack of trees available to soak up fresh rain water causes landslides and flooding. Some areas, like the border of the Dominican Republic and Haiti are seeing higher and higher water levels. The water has reached the rooftops of what were once houses, and continue to spill over into the border crossing zone. Nothing is being done to prevent it or change the location of the border crossing zone. Caption and Photo source: ©© Gina Vince

Excerpts;

A fire has destroyed or seriously damaged 1,500 hectares (3,700 acres) of vegetation in a Patagonia nature preserve in southern Chile.

The fire at Torres del Paine National Park that began on Tuesday near a trail “was very likely caused by human negligence.”

Glaciers and Andean lakes lie alongside natural forests and the Patagonian steppe at the semi-desert nature preserve visited by several thousand tourists each year…
