World’s river systems: Stressed OUT
March 24, 2014 02:16 PM - Robin Blackstone, ENN
According to the World Resources Institute (WRI) many, if not most of the world’s rivers are stressed. Determining a systems water stress is based upon measuring the ratio of total water withdrawals to the available renewable supplies within the catchment area. Rivers are an indispensible resource for our communities and ecosystems and we are hugely dependent upon them for agriculture, industry and our natural systems. A stressed river system can severely threaten regional water security and economic growth, and potentially contribute to political instability—especially in the absence of an adequate water-management plan.
Road to environmental destruction
March 21, 2014 11:40 AM - ENN Editor
Roads are considered connectors of human development providing opportunities for economic success and communication but the flip side of this network is that it has also brought enormous destruction to our fields and forests. With forest destruction comes increased human development and ecological degradation. Recent mapping and modeling has been done to document and measure forest destruction in an initiative by the Ames Research Center of NASA and ENN affiliate, Mongabay.

According to WaterSense, an Environmental Protection Agency Partnership Program, household leaks waste more than a trillion gallons of water annually. Our urgency to conserve often depends upon what part of the country we live. But officials predict that at least 36 states that will experience some sort of water shortage.
No more stinky cotton!
March 19, 2014 10:18 AM - Robin Blackstone, ENN
Following the eradication of the cotton boll weevil in the late 1990s cotton growers began to notice an influx of a new pest, stink bugs. Stink bugs feed on bolls on the bottom portion of the plant, puncturing squares causing young cotton bolls to drop and staining, matting and shrinking cottonseeds through heavy stink bug feeding. Injured locks or bolls may fail to open. Resultantly damage caused by stink bugs introduce bacteria, such as Pantoea agglomerans and fungi that cause boll rots. Currently stink bugs are ranked among the most damaging insect pests of cotton in the southeastern United States.
Invasive Burmese Pythons Can Find Their Way Back Home
March 19, 2014 10:15 AM - Allison Winter, ENN
There are multiple ways to deal with a critter that may find its way into your home. The most humane — catch it and release it back into its natural habitat perhaps a couple of miles away from your neighborhood. But this might not work for all species as a new study reveals that Burmese pythons are able to find their way back home even when moved far away from their capture locations.
COLLEGIATE CORNER: Offshore oil drilling: is it really necessary?
March 18, 2014 10:32 AM - Christian Ramirez, Class of 2015, Wakefield High School, Arlington, VA
As we all know, oil is a very important energy resource the world needs for its everyday life. It is known that not only do most of the countries on the planet use it, but also it is a scarce resource, which means that in the near future, there will no longer be enough available oil that could be drilled and processed for future endeavors. The demand for oil has increased significantly throughout the past few years and other ways of obtaining this resource must be used more often. A form of oil drilling has emerged which is dangerous and is known as offshore drilling. Sounds like a good plan at first, going to the ocean where more oil can be found and at a faster rate, but is it really worth it? There should be an alternate to offshore drilling because of the many horrific and unfair problems that it brings to Americans, animals, and the overall environment.
A dust induced monsoon in India
March 17, 2014 10:23 AM - ENN Editor
Another sign of our global connectedness has manifested itself in a new satellite analysis linking dust in North Africa and West Asia with stronger monsoons in India. The study shows that as airborne dust from North Africa and West Asia absorbs sunlight it warms the air and strengthens the eastern winds carrying moisture. The heavy laden air generates a monsoon rainfall about a week later in India thereby explaining one way that dust can affect the climate, filling in previously unknown details about the Earth system.
Antarctic ecosystem due to change radically with climate change

According to researchers the Ross Sea will "be extensively modified by future climate change" in the coming decades creating longer periods of ice-free open water and affecting life cycles of all components of the ecosystem in a paper published and funded by the National Science Foundation (NSF). The researchers have drawn their information from the Regional Ocean Modeling System, a computer model that evaluates sea-ice, ocean, atmosphere and sea-shelf.
Rooftop considerations amidst climate change
March 13, 2014 11:54 AM - Robin Blackstone, ENN
As the realities of climate change set in, so too are realizations that building technologies impact both internal and external environments. The percentage increase of asphalt and blacktopped roofs create urban heat islands. Resultantly cities have become earth's newest desserts exhibiting high temperatures and arid conditions with little vegetation. Urban expansion as a stand-alone factor (omitting greenhouse gas-induced climate change considerations) is expected to raise temperatures by roughly six degrees. Because of this, scientists are now exploring new technologies to cope with the new reality.
Sustainable urban lawns
March 12, 2014 01:16 PM - robin Blackstone, ENN
Concern for the homogenization of America's urban landscape prompted a recent research study into the care and maintenance of residential landscapes. The study demonstrated fewer similarities than expected but the concern, according to researchers is that "Lawns not only cover a larger extent [of land] than any other irrigated 'crop' in the U.S., but are expected to expand in coming decades. The researchers go on to point out that the potential homogenization of residential lawn care has emerged as a major concern for carbon, nitrogen, phosphorus and water flows."
