Agricultural practices to reduce runoff
May 23, 2015 07:27 AM - South Dakota State University via ScienceDaily.
The same spring rains that lessen producers' concerns about drought can also lead to soil erosion and nutrient runoff. Keeping soil and fertilizers where they belong -- in the field -- benefits producers and the environment.
No-till farming, cover crops and rotational grazing will help producers reduce surface runoff to improve soil and water quality, according to South Dakota Agricultural Experiment Station researcher Sandeep Kumar, an assistant professor in the SDSU plant science department.
Climate change and human rights
May 22, 2015 07:15 AM - Eniko Horvath, Triple Pundit
Last month, a Peruvian farmer called on German energy company RWE to pay its fair share to protect his home from imminent flooding caused by a glacial lake melted by global warming. “For a long time, my father and I have thought that those who cause climate change should help solve the problems it causes,” Saul Luciano Lliuya told the Guardian. He holds that RWE, one of Europe’s largest emitters of carbon, has contributed to the greenhouse effect causing glacial melting that endangers his home, along with many others in the city of Huaraz.
Lliuya’s story illustrates the tangible human impacts of climate change, which can easily be forgotten amidst high-level debates over carbon emissions reductions. This is a key year for climate action by both governments and companies.
National-scale effort addresses pollinator declines
May 20, 2015 03:51 PM - Puneet Kollipara, Science/AAAS
A new White House plan to promote the health of bees and other pollinators calls for boosting research into ongoing population declines—and potential solutions. The plan, released yesterday, also recommends numerous measures to address growing concerns about the threat that bees, birds, butterflies, and other pollinators face from multiple factors, including pathogens, pesticides, climate change, and habitat loss. By addressing scientific knowledge gaps, the research should make the plan’s suggested measures much more effective, the report says.
Recycling electronics is getting more difficult as devices get smaller and smaller
May 19, 2015 06:53 AM - RP Siegel, Triple Pundit
The last several decades have brought a global explosion of electronics with a huge impact on quality of life and communications, as well as the world economy.
But, like most big human-induced changes, there were unintended consequences, primarily in the form of the mountains of waste that resulted as products quickly became obsolete and tossed out only to be replaced by others with an equally short lifespan. (One study showed that 25 percent of electronic devices were used less than 500 hours before being discarded.) This is exacerbated by the fact that electronic waste can contain dangerous materials including lead, mercury and cadmium.
Happy Endangered Species Day!
May 15, 2015 08:43 AM - Editor, Population Matters
Started in 2006, Endangered Species Day is “a celebration of wildlife and wild places” intended to promote the “importance of protecting endangered species and everyday actions people can take to help protect them”. Every year on the third Friday in May — and throughout the month — zoos, aquariums, parks, botanical gardens, wildlife refuges, museums, schools, community centers, conservation groups and other organizations hold tours, speaker presentations, exhibits, children’s activities and more to commemorate the Day.
Urban development causes damage and loss of valuable ecosystems
May 14, 2015 06:29 AM - Harvard University
All land is not created equal. Some ecosystems do triple duty in the benefits they provide to society. Massachusetts forests, for example, filter public drinking water while also providing habitat for threatened species and storing carbon to combat climate change.
Ecologists and conservation groups single out the hardest-working ecosystems – called “hotspots” – for their exceptional conservation value. A new study published today in the Journal of Applied Ecology reports that the number of ecosystem hotspots has increased in Massachusetts over the past decade, with more and more hotspots popping up in metro Boston.
But, the study authors say, more hotspots may not be a good thing.
New study examines the air quality impacts of fracking wells
May 13, 2015 03:34 PM - Oregon State University
People living or working near active natural gas wells may be exposed to certain pollutants at higher levels than the Environmental Protection Agency considers safe for lifetime exposure, according to scientists from Oregon State University and the University of Cincinnati.
The researchers found that hydraulic fracturing – a technique for releasing natural gas from below-ground rock formations – emits pollutants known as PAHs (polycyclic aromatic hydrocarbons), including some that are linked with increased risk of cancer and respiratory ailments.
“Air pollution from fracking operations may pose an under-recognized health hazard to people living near them,” said the study’s coauthor Kim Anderson, an environmental chemist with OSU’s College of Agricultural Sciences.
Germany is key market for the Tesla Home Battery system
May 5, 2015 06:24 AM - EurActiv
Electric car pioneer Tesla unveiled a "home battery" last week which its founder Elon Musk said would help change the "entire energy infrastructure of the world". Environmentally-conscious German customers are targeted as potential buyers of the product.
The Tesla Powerwall, unveiled on Thursday (30 April), can store power from solar panels, from the electricity grid at night when it is typically cheaper, and provide a secure backup in the case of a power outage.
In theory the device, which typically would fit on the wall of a garage or inside a house, could make solar-powered homes completely independent of the traditional energy grid.
Solar power in Scotland is not a little enterprise
May 4, 2015 07:25 AM - ClickGreen staff, ClickGreen
The call by WWF Scotland follows the publication of new figures revealing that there was enough sunshine in April to have met more than 100% of the electricity needs of an average home in Scotland or 99% or more of an average household’s hot water needs.
Wind turbines in Scotland also generated enough electricity on average to supply the electrical needs of 69% of Scottish households - 1.66 million homes.
Last month, it was announced that work on Scotland’s largest solar park will start later this year in Angus.
Fracking wastewater and the risk to our food
May 3, 2015 06:42 AM - Roy L Hales
Unconventional drilling creates a huge amount of waste, some of which is being sprayed onto farmer’s fields. A 2005 report from New Zealand stated cows grazing on “dump farms” have elevated levels of hydrocarbons. “Cows are allowed to graze on land with high levels of hydrocarbons without any punishment and their food products are allowed to go to market without government testing,” a Green Party MP said last year. It is happening in Canada too. The field above is northwest of Calgary. Former energy consultant Jessica Ernst said, “We are eating & drinking drilling and fracking waste.”
“When they are drilling deep horizontal wells, they go a great distance and this produces a lot of drilling waste. It is toxic. There are a lot of naturally occurring toxics that are brought up. It is often radioactive. I have documentation that the formations they want to frack are radioactive. This comes up with metals and BTEX (Benzene, Tolulene, Ethylbenzyne, Xylenes) carcinogens plus the mystery additives which companies refuse to disclose,” said Ernst.
