Hawaii's Fishermen: Scapegoats for Forces Outside their Control
June 19, 2013 09:26 AM - Andrew Burger, Global Warming is Real
Climate change is affecting fisheries in the Western Pacific and around the world, but a host of other factors, including land use, are threatening fisheries and the health and integrity of marine ecosystems. Aiming for sustainable fisheries, marine policymakers, resource managers, fishermen and other stakeholders are increasingly looking to take a more holistic, integrated approach to fisheries management, as evidenced during the latest meeting of the Western Regional Fishery Management Council (WRFMC) meeting, which was held in Oahu. Often blamed for overexploiting fish stocks, local fishermen in Hawaii are keenly aware of external impacts on the health and integrity of marine ecosystems and fish populations. At the latest WRFMC meeting in Honolulu, they argued in support of taking a more comprehensive ecosystems management approach, specifically zooming in on how land use and associated runoff from cities, agriculture and industry are harming marine ecosystems and fisheries.
Aquatic Environment Biodiversity Threatened by Pesticides
June 18, 2013 03:09 PM - Allison Winter, ENN
The use of pesticides have been debated for some time now, as research indicates their use can have a negative effect on the environment. As an agent meant to prevent, destroy or mitigate any pest, pesticides target unwanted plants and animals that can alter ecosystems, cause nuisance, or spread disease. Besides potentially being toxic to humans and other animals, new research conducted by an international team of scientists has revealed that pesticides are responsible for reducing regional biodiversity of invertebrates by up to 42 percent.
Singapore chokes on haze from deforestation fires
June 18, 2013 08:58 AM - Rhett Butler
Singapore and Malaysian officials have asked Indonesia to take "urgent measures" to address forest fires in Sumatra that are sending choking haze northward, reports AFP. Singapore's air pollution index is at the worst level since 2006, when Sumatra last experienced severe fires. The city-state's Pollutant Standards Index on Monday topped 150, well above the "unhealthy" threshold of 100, according to the National Environment Agency (NEA) web site.
Memory Loss and Gain
June 17, 2013 08:35 AM - Andy Soos, ENN
Would it not be nice to take a pill and regain that elusive memory? We are all forgetful at times and without a clue as to how to get it better. Memory improved in mice injected with a small, drug-like molecule discovered by UCSF San Francisco researchers studying how cells respond to biological stress. The same biochemical pathway the molecule acts on might one day be targeted in humans to improve memory, according to the senior author of the study, Peter Walter, PhD, UCSF professor of biochemistry and biophysics and a Howard Hughes Investigator.
11,000 barrels of oil spill into the Amazon's Coca River
June 13, 2013 09:02 AM - Jeremy Hance, MONGABAY.COM
On May 31st, a landslide ruptured an oil pipeline in Ecuadorean Amazon, sending around 11,000 barrels of oil (420,000 gallons) into the Coca River. The oil pollution has since moved into the larger Napo River, which borders Yasuni National Park, and is currently heading downstream into Peru and Brazil. The spill has occurred in a region that is notorious for heavy oil production and decades of contamination, in addition to resistance and lawsuits by indigenous groups.
Panama expects benefits from world's first GM salmon
June 11, 2013 03:45 PM - Eva Aguilar, SciDevNet
Panama's researchers have played a key role in creating a rapidly growing salmon that may soon become the world's first commercially sold genetically modified (GM) animal. The US's Food and Drug Administration (FDA) has ruled the consumption of GM salmon to be as safe as conventional Atlantic salmon, and is now analyzing public comments on its environmental impact as the final part of the approval process. If the FDA permits the transgenic salmon to be imported for human consumption — which the firm that developed the fish hopes will be granted this year — the research station in Panama that is studying the GM salmon would switch to growing it for the US market.
Vegetable Oil is OK
June 8, 2013 07:49 AM - Roger Greenway, ENN
With all the talk about the virtues of Olive Oil, you might get the idea that common, inexpensive vegetable oil is not good for you. A new study has shown that consuming vegetable oil has some health benefits! A typical American consumes approximately 3 or more tablespoons of vegetable oil each day. Vegetable oils, like those from soy, corn and canola, are a significant source of calories and are rich in linoleic acid (LA), which is an essential nutrient. Since the 1970s, researchers have known that LA helps reduce blood cholesterol levels, and for decades, scientists have known that consuming LA can help lower the risk of heart disease. However, some experts have been claiming recently that Americans might be getting too much of a good thing. A new study from the University of Missouri contradicts that claim.
Denmark's NOx Tax
June 7, 2013 06:12 AM - EurActiv
Denmark's tax on nitrogen oxide emissions, which was raised during the financial crisis, could be scrapped if it's proven to have a negative impact on jobs and competitiveness. The centre-left Danish government, which was formed in October 2011, decided at the end of that year to raise the tax from 5 to 25 Danish crowns (from €0.7 to 3.4) per kilo of nitrogen oxide NOx emissions. The tax was introduced on 1 July 2012. The increased NOx tax was adopted after long debates in the Danish parliament where opposition parties warned it would be expensive not only for companies emitting NOx, but for all businesses.
Small island states told to build wider ocean expertise
June 6, 2013 08:45 AM - Yojana Sharma, SciDevNet
With rising concern about ocean degradation and the sustainable use of ocean resources, small island states must build scientific expertise that goes beyond their national needs and that benefits the oceans generally, a meeting of UN scientific experts has heard. Small island developing states (SIDS) are the "custodians" of vast ocean spaces that are important for global food security, biodiversity, natural resources and carbon sequestration, and broader sustainable ocean policies will in turn enhance their own economic development, say experts.
Has power in the electric vehicle market switched from the US to China?
June 5, 2013 02:20 PM - Move Forward, Electric Forum
When we think of automobiles the likelihood is that the US is a country which will spring to mind and then perhaps other operations in the Far East, Europe and beyond. For many years the likes of Ford and General Motors have dominated the automobile industry giving the US government enormous power to lead while the rest follow. However, there is a growing concern that the US government may well be losing control of the electric vehicle market with the Chinese authorities now keener than ever to invest in this new technology. It seems almost inconceivable that President Obama, who has recently been forced to renege on his 1 million electric vehicle target, should lose control of the electric vehicle industry to China.
