Earthquakes Triggered by Dams (Besides underground water extraction)

Earthquakes Triggered by Dams (Besides underground water extraction) | Yan's Earth | Scoop.it
RT @americanrivers: New research: earthquakes can be induced by dams.

In a paper prepared for the World Commission on Dams, Dr. V. P Jauhari wrote the following about this phenomenon, known as Reservoir-Induced Seismicity (RIS): "The most widely accepted explanation of how dams cause earthquakes is related to the extra water pressure created in the micro-cracks and fissures in the ground under and near a reservoir. When the pressure of the water in the rocks increases, it acts to lubricate faults which are already under tectonic strain, but are prevented from slipping by the friction of the rock surfaces."

Given that every dam site has unique geological characteristics, it is not possible to accurately predict when and where earthquakes will occur. However, the International Commission on Large Dams recommends that RIS should be considered for reservoirs deeper than 100 meters.

Goa's overcrowded beaches and countryside have seen garbage piling up, with the state failing to put in place an effective garbage disposal mechanism.
Beer bottles, empty tetra packs and potato wafer packets are ubiquitous. Assorted dry waste litters the beach, left behind by irresponsible tourists and locals.
Neither the coastal village panchayats nor the tourism department is equipped to safely dispose of the garbage collected by sweepers.
Esperance Fernandes believes that the move by the village panchayat would help minimise the filth on the beach as well as set an example for other coastal village panchayats.

Enthusiastic Student Scientist Wins Attention for Promising Solar Clean Water Project

Enthusiastic Student Scientist Wins Attention for Promising Solar Clean Water Project | Yan's Earth | Scoop.it
Deepika Kurup's green and sustainable water purification project wins her honors as "America’s Top Young Scientist"...

Deepika designed a simple but elegant experiment. She created three UV-treatment vessels with catalytic rods: two using each photocatalyst on its own and a third with a combined TiO2-ZnO coating. A fourth plastic bottle without any photocatalyst served as a control. Deepika then sampled water from the bottles every three hours, using an incubator she developed herself to grow colonies in order to test the water contamination levels.

Deepika was able to prove that the combined TiO2-ZnO rods significantly accelerated the treatment time necessary to achieve clean water using the sun for treatment.

Rice agriculture accelerates global warming: More greenhouse gas per grain of rice

Rice agriculture accelerates global warming: More greenhouse gas per grain of rice (sciencedaily): Share With Fr...

Methane in rice paddies is produced by microscopic organisms that respire CO2, like humans respire oxygen. More CO2 in the atmosphere makes rice plants grow faster, and the extra plant growth supplies soil microorganisms with extra energy, pumping up their metabolism. Increasing CO2 levels will also boost rice yields, but to a smaller extent then CH4 emissions. As a result, the amount of CH4 emitted per kilogram of rice yield will increase. Rising temperatures were found to have only small effects on CH4 emissions, but because they decrease rice yield, they also increase the amount of CH4 emitted per kilogram of rice. "Together, higher CO2 concentrations and warmer temperatures predicted for the end of this century will about double the amount of CH4 emitted per kilogram of rice produced.,"

Double dose of pesticide poses new danger for bumblebees

Double dose of pesticide poses new danger for bumblebees | Yan's Earth | Scoop.it
The combination of two pesticides commonly used on UK fields can have damaging effects on the behaviour of bumblebees and cause their colonies to collapse, new research by British scientists has found.

The findings, which come from a Government-funded study, represent the fifth major piece of research to appear this year linking the worldwide and worrying declines of bees to pesticides, and in particular to the use of the relatively new nerve-agent pesticides, the neonicotinoids.

This new study is considered particularly important because bees forage widely so are likely to encounter more than one type of pesticide.

Published last night in Nature online, the study reports that exposure to two commonly used pesticides, one a neonicotinoid and the other from a different pesticide family, a pyrethroid, at concentrations approximating what might be found in the field, impaired the natural foraging behaviour of bumblebees. This led to increased numbers of deaths and in some cases the failure of colonies. The compounds involved were made by major agrochemical manufacturers: the most widely used neonicotinoid, imidacloprid, manufactured by Bayer and already implicated in problems with bees in earlier studies, was one, while the pyrethroid was lambda-cyhalothrin, originally developed by Syngenta.

Traditional breeding outperforms genetic engineering

Traditional breeding outperforms genetic engineering | Yan's Earth | Scoop.it
Contrary to claims by seed companies, GM crops actually give lower yield, disturbs the plants’ genetic structure and do not assure safety, according to a section of scientists (RT @GMWatch: Traditional breeding outperforms genetic engineering

In April 2009, the Union of Concerned Scientists (UCS) published a report ‘Failure to Yield’ confirming that “after 20 years of research and 13 years of commercialisation, GM crops have failed to increase yields” and that “traditional breeding outperforms genetic engineering hands down”.

In a letter written to the Prime Minister of India in 2009, as many as 17 distinguished scientists from the U.S., Canada, Europe and New Zealand pointed out that the claims relating to higher yield and protection of environment made for GM crops are absolutely false.

allAfrica.com: Africa: Vital Economic and Environmental Role of Wetlands Must Be Recognized to Avoid Further Degradation and Losses

allAfrica.com: Africa: Vital Economic and Environmental Role of Wetlands Must Be Recognized to Avoid Further Degradation and Losses | Yan's Earth | Scoop.it

Global and local water cycles are strongly dependent on healthy and productive wetlands, which provide clean drinking water, irrigation for agriculture, and flood regulation, as well as supporting biodiversity and propping up industries such as fisheries and tourism in many locations.

Yet, despite the high value of these ecosystem services, wetlands continue to be degraded or lost at an alarming pace, according to The Economics of Ecosystems and Biodiversity (TEEB) for Water and Wetlands report, released for consultation today at the 11th meeting of the Conference of the Parties to the Convention for Biological Diversity.

Half of the world's wetlands were lost during the twentieth century - due mainly to factors such as intensive agricultural production, unsustainable water extraction for domestic and industrial use, urbanization, infrastructure development and pollution. The continuing degradation of wetlands is resulting in significant economic burdens on communities, countries and businesses.

Filling Our Landfills (From 18,500 in 1979; only 1754 left in 2006) - "Time for 3Rs"

Filling Our Landfills (From 18,500 in 1979; only 1754 left in 2006) - "Time for 3Rs" | Yan's Earth | Scoop.it

Landfill statistics show that in 1979, approximately 18,500 landfills were available to receive trash all across the United States. In 1990, just 11 years later, this number was drastically decreased by almost 60%. According to the landfill statistics given by the Environmental Protection Agency (EPA), in 1988 there were 7,924 landfills available in the US. In 2006, there were only 1,754 left. This continued decrease in available landfill space is relative to the amount of trash that has been increasing in great proportions.

At present, the biggest landfill in the US is located in Apex, Las Vegas, Nevada. This location alone received 3,824,814 tons of trash in 2007. The second largest is located in Puente Hills, Whittier, California that received 3,756,718 tons of trash in the same year.

In what sounds more like alchemy than science, a small British company has figured out a way to create gasoline from air and water. To do so, engineers at Air Fuel Synthesis (AFS) produced five litres (1.3 gallons) of the fuel by extracting carbon dioxide from air, and hydrogen from water, which was then combined in a reactor with a catalyst to create methanol. This methanol was then converted into gasoline.
The entire chemical process to create this synthetic hydrocarbon liquid took three months, and is part of a $1.6 million dollar project to create a sustainable and environmentally friendly fuel. And because renewable energy was used to power the process, the scientists say it may be possible to create carbon-neutral fuel en masse that can be used like regular gasoline.

Deadly 2011 earthquake linked to groundwater extraction (man-made quakes?)

Deadly 2011 earthquake linked to groundwater extraction (man-made quakes?) | Yan's Earth | Scoop.it
WASHINGTON (Reuters) - An earthquake that killed nine people in Spain last year may have been triggered by decades of pumping water from a nearby natural underground reservoir, suggesting human activities (RT @leblancetienne: Issh RT @Lactu_Borde:...

The study's lead author, Pablo Gonzalez of the University of Western Ontario, said he and his colleagues reckoned that the quake was related to a drop in the level of groundwater in a local aquifer, which can create pressure at the Earth's surface.

To test that theory, they used satellite data to see how the terrain was deformed by the earthquake, and found that it correlated to changes in the Earth's crust caused by a 273-yard (250-metre) drop in the natural groundwater level over the last five decades due to groundwater extraction.

Seeds of hope amidst Philippine floods: Rice that can survive underwater - this is "smart" agriculture!

Seeds of hope amidst Philippine floods: Rice that can survive underwater - this is "smart" agriculture! | Yan's Earth | Scoop.it
Amidst horrendous flooding around Manila and major rice-growing across Luzon in the Philippines, some good news has emerged for rice farmers -- Submarino rice -- rice that can survive around two weeks of being under water.

Submarino rice was bred by the International Rice Research Institute (IRRI) and can survive floods if they occur before flowering. The latest Submarino variety was released in the Philippines in 2009 and disseminated and promoted by the Philippine Department of Agriculture (DA) and the Philippine Rice Research Institute (PhilRice) to help rice farmers in times of floods and typhoons.

Philippine Secretary of Agriculture Proceso Alcala said, "IRRI is one of our partner agencies that studies and promotes the propagation of Submarino rice varieties that can recover even after being submerged for 14 days."

Panel recommends 10-year moratorium on Bt crop trial - The Economic Times

Panel recommends 10-year moratorium on Bt crop trial - The Economic Times | Yan's Earth | Scoop.it
A panel of scientists set up on the orders of the Supreme Court has recommended a 10-year moratorium on field trials of all genetically modified or Bt food crops.

The panel unanimously recommended a moratorium until specific sites for conducting field trials have been designated and certified, and sufficient mechanisms for monitoring the trials put in place. The experts have said that a panel of scientists, qualified in evaluation of the biosafety data of GM crops must be appointed to scrutinise and analyse safety data. They suggest mandatory inclusion of preliminary bio-safety tests prior to field trials, including sub-chronic toxicity in small animals.

Addressing concerns over the impact on health, environment and other social-economic consideration, the panel's interim report called for a moratorium on field trials of herbicide-tolerant crops. The moratorium should be in place until an independent committee of experts and stakeholders "has examined and assessed the potential impact of herbicide tolerant technology and its suitability in the Indian context", the report said.

A dramatic picture taken by Michael Nolan has been... | Yan's Earth | Scoop.it

A dramatic picture taken by Michael Nolan has been dubbed the face of Mother Nature crying on a canvas of melting ice and cascading water on a Norwegian Glacier. Randy Schutt discovered this amazing photo which shows a crying face in an ice cap located on Nordaustlandet, in the Svalbard archipelago of Norway. The tears of this natural sculpture were created by a waterfall of glacial water cascading from one of the face’s eyes, thus painting an alarming picture warning the world about the effects of global warming. Michael Nolan is a marine photographer and environmental lecturer. He has captured this picture while on an annual voyage to observe the glacier and surrounding wildlife. It’s best to quote Nolan’s words on this:

“This is how one would imagine mother nature would express her sentiments about our inability to reduce global warming. It seemed an obvious place for her to appear, on a retreating ice shelf, crying.”
