Interview: Bringing Civility and Diversity to Conservation Debate

For the past few years, an acrimonious debate has been ranging between two camps of conservationists. One faction
“Jane
Jane Lubchenco
advocates protecting nature for its intrinsic value. The other claims that if the degradation of the natural world is to be halted, nature’s fundamental value — what nature can do for us — needs to be stressed. The tone of the rhetoric has led to a petition, published this month in the journal Nature, that criticizes both sides for indulging in ad hominem attacks and unproductive arguments that have devolved into “increasingly vitriolic, personal battles.” In an interview with Yale Environment 360, Jane Lubchenco, former head of the National Oceanic and Atmospheric Administration, explains why she and her co-signatories are calling for a more “inclusive conservation” and why the bickering needs to stop.

26 Nov 2014: Aerodynamic Upgrades to
Large Trucks Would Cut Fuel Use Steeply

The fuel consumption of the 2 million tractor-trailer trucks hauling cargo across the U.S. — which currently

Airflow patterns around a tractor-trailer truck
burn 36 billion gallons of diesel fuel per year — could be cut by billions of gallons through the use of drag-reducing devices, according to researchers at Lawrence Livermore National Laboratory. In wind tunnel tests, researchers fitted a scale-model truck with two types of devices designed to reduce drag and improve aerodynamics: a trailer skirt, which consists of panels affixed along the lower side edges of a trailer, and a boat tail fairing, which is affixed to the back of the trailer to reduce the size of its wake. The researchers found that using the devices in combination — technology currently installed on only 3 to 4 percent of the nation’s large trucks — reduced the aerodynamic drag by as much as 25 percent, which translates to a 13-percent decrease in fuel consumption. If the U.S. tractor-trailer fleet were to improve its fuel economy by 19 percent, which the researchers say is achievable, 6.5 billion gallons of diesel fuel would be saved each year, avoiding 66 million tons of carbon dioxide emissions.

25 Nov 2014: China’s Lake Ebinur Has Been
Shrinking Dramatically, NASA Image Shows

As this NASA satellite image shows, Lake Ebinur, located in northwestern China near the border of

Enlarge

China's Lake Ebinur
Kazakhstan, has shrunk by 50 percent since 1955 as a result of development, agriculture, and natural fluctuations in precipitation. The lake’s saline water is light blue, and the dried lake bed appears white due to salts and other minerals that have been left behind as the water evaporates. The lake’s size fluctuates from year to year due to natural variations in snowmelt and rainfall, and human activity also plays a key role, Chinese researchers say. The nearby city of Bole, with a population of 425,000, consumes significant amounts of water, and farmers irrigate their crops — especially cotton — with water that would otherwise flow into the lake, researchers say. Frequent saline dust storms contribute to desertification, damage soils, harm wetlands, and may be hastening the melting of snow and glaciers downwind, researchers say.

24 Nov 2014: Record Number of Rhinos Poached In South Africa, Government Says

South African officials have announced that 1,020 rhinos have been killed so far in 2014 — a total that

surpasses last year’s record slaughter of 1,004 of the endangered animals. Poaching has been on the rise in South Africa, home to the world’s largest population of rhinos, since 2007, when only seven rhinos were killed. The sharp increase is occurring despite steps by the government to improve enforcement and introduce new technologies and intelligence-gathering methods to curb poaching, Mongabay reports. As of 2010, South Africa was home to more than 18,000 white rhinos — over 90 percent of the global population — and nearly 2,000 black rhinos. The animals are being killed for their horns, which are in high demand in China and Vietnam for their supposed, but unproven, medicinal qualities.
