Electric Airplane Debut
Offers Hopes for Cutting Emissions

dioxide emissions by an order of magnitude. The E-Fan aircraft has two, 30-kilowatt electric motors powered by a series of lithium-ion batteries in the wings of the plane, as well as a 6-kilowatt electric motor in the wheel to provide extra power during takeoff and taxiing. Despite incorporating highly energy-efficient and aerodynamic design elements, however, the E-Fan has only a one-hour range and cannot leave the vicinity of the airport. Airbus says that future designs will rely on electric-hybrid engine technology and that by 2050 such airplanes should be able to accommodate 70 to 80 passengers on a three-hour flight. The plans were spurred, in part, by the European Union's Flight Path 2050
, which aims to reduce the aviation sector's nitrous oxide emissions by 90 percent, noise pollution by 65 percent, and carbon dioxide emissions by 75 percent by 2050. "It's a very different way of flying," said Jean Botti, a technology officer at Airbus Group, "absolutely no noise, no emissions."

Donors Commit $220 Million
To Protect and Expand Huge Amazon Reserve
A coalition of private donors and government funders has pledged $220 million
over the next 25 years to better protect the Amazon Region Protected Areas (ARPA), the world’s largest protected area network. WWF, the World Bank, the Gordon and Betty Moore Foundation, the Inter-American Development Bank, and more than a dozen other donors are contributing funds to the initiative, which also will add another 8.9 million hectares of Amazon rainforest to the ARPA program
, driving the total to more than 60 million hectares. That’s 232,000 square miles, an area larger than France. Most of the funds will be used to better police and enforce environmental laws on ARPA territory, which includes 90 parks and comprises 15 percent of the Brazilian Amazon. "The explosion in demand for natural resources has made our parks and world heritage sites vulnerable," said WWF president Carter Roberts. The initiative is also upgrading long-neglected parks and creating sustainable-use reserves for local communities and indigenous people.

Run-of-River Hydropower Set
For Big Gains, Turbine Maker Predicts
A type of hydroelectric technology known as "run-of-river" hydropower is set to grow 10-fold over the next decade

Hugh Keenleyside Dam
according to Dutch turbine maker Tocardo International BV. Run-of-river hydropower stations redirect part of a waterway through a diversion to spin turbines and generate electricity. Run-of-river is considered a more benign type of hydropower than large dam projects because it is a smaller-scale technology that doesn't create large upstream reservoirs that flood ecosystems and disrupt a river's natural flow. Some conservation groups are concerned
that problems with migratory fish passage and other environmental issues could outweigh the power-generating potential of run-of-river hydro projects. The company implemented its first project to harness tidal streams at Den Oever, Holland, and it has been operating for five years.
A Personal Note on Peter Matthiessen,
Who Wrote Eloquently of the Natural World
For an editor, the prospect of working with Peter Matthiessen was intimidating. He was one of our finest writers, and he wrote with such poetic precision and lyrical grace that at first it felt presumptuous to propose
any changes to his writing at all. That feeling was heightened by his strong physical presence — an odd mix of Manhattan patrician, rugged outdoorsman, and Zen priest (all of which he was). And yet when I worked as his editor on several magazine articles in the 1990s, it was an immensely satisfying experience. He listened Zen-like, carefully considering all my editing suggestions (with him, they were suggestions
only), and to my delight, accepted almost all of them. Matthiessen died on April 5 at the age of 86, near the Long Island waters he so loved to fish. Read more of e360 editor Roger Cohn’s appreciation of Matthiessen.

Consumer Products Giants
Commit to Deforestation-Free Palm Oil
Two major consumer products companies — General Mills and Colgate-Palmolive — have committed
to using palm oil in their products that does not come from lands cleared from tropical forests, adding to the wave
of corporations that have pledged measures to protect southeast Asian rainforests. The consumer giants' new policies go beyond standards set by the industry's main certification body and include provisions to protect wildlife-rich rainforests, carbon-dense peatlands, and the rights of local communities. Environmental groups are welcoming the commitments, though some believe the companies' pledges should go further. The Union of Concerned Scientists questions General Mills' definition of "high carbon stock" forests, while Greenpeace is urging Colgate-Palmolive to move implementation up to 2015 from 2020. Environmental groups are hopeful that new commitments will pressure Proctor & Gamble, the last remaining consumer products giant without a similar pledge, to adopt deforestation-free palm oil policies.
An e360 Interview with Wendell Berry:
Strong Voice for Local Farms and the Land

environmental movement. At age 79, Berry still speaks eloquently about the importance of local communities and of caring for the land, while warning about the destructive potential of industrialization and technology. In an interview with Yale Environment 360
, he talked about his Kentucky farm and why he has remained there, why sustainable agriculture faces an uphill battle, and why strong rural communities are important. “A deep familiarity between a local community and a local landscape is a dear thing, just in human terms,” Berry said. “It’s also, down the line, money in the bank, because it helps you to preserve the working capital of the place.”

Rewritable Paper and Water Ink
Could Cut Paper Waste, Scientists Report
A new type of rewritable paper that uses water as ink could slash the amount of paper that's wasted daily, researchers say
. The paper contains hydrochromic dyes — chemicals that change color when wet — and a single
page can be reused dozens of times, the scientists report in Nature Communications
. Other types of rewritable papers have been developed, but they are all more expensive and energy-intensive to produce, and some versions use inks that pose environmental and safety hazards. The new system costs less than 1 percent of standard inkjet printing, the researchers estimate, primarily because ink cartridges are expensive. The researchers found they could refill cartridges with water and use them, along with the rewritable paper, in typical desktop printers. Print on the rewritable paper is only visible for about 22 hours, or as long as it takes the paper to dry completely. The scientists note that, while 90 percent of business information is retained on paper, most printed documents are read only once before being discarded.

Shrinking Household Size
May Offset Progress in Curbing Population
Household size — the number of people living together under one roof — has been shrinking worldwide, and the trend could have major consequences for resource consumption
, new research finds
. Although global population growth has been somewhat curbed in the developed world, the number of households has continued to grow at a much faster pace in nearly all countries, Michigan State University researchers found. Average household size in developed nations declined from approximately five members in 1893 to 2.5 in 2000, while the rapid decline in household size in developing nations began around 1987, according to the research
, which analyzed trends between the years 1600 and 2000. Smaller households are typically less efficient, with fewer people using proportionally more land, water, and energy. Constructing housing units also consumes lumber and building supplies, and generally requires building more roads and commercial areas. "This will put enormous strain on the environmental life support system we rely on, even if we achieve a state of zero population growth," one study author said.
Photo Essay: In New Orleans, an
Architect Makes Water His Ally
Dutch Dialogues II
No city in the United States faces as grave a threat from flooding, hurricanes, and rising seas as New Orleans, part of which lies below sea level. But New Orleans architect David Waggonner
and his associates, learning lessons from the Dutch
, have proposed a revolutionary vision for New Orleans that seeks to make an asset of the water that surrounds the city, remaking unsightly canals into an important and scenic part of the landscape and mimicking nature to store rainfall. Waggoner’s firm has been chosen to help develop a Greater New Orleans Urban Water Plan
, a first step in what could be a multi-billion dollar project to redesign the ways in which the region co-exists with water. “To sustain the city in this difficult site in an era of rising seas and more extreme weather, we must convert our necessities into niceties, into desirable places that connect with people and culture,” Waggonner says.

NASA Images Show Severity
Of California's Record-Setting Drought
A pair of NASA images, taken a year apart, show the profound impacts
of California's current drought, which Gov. Jerry Brown said yesterday poses a major threat to California's environment
and economy. A satellite image taken last Saturday shows virtually no snow cover
in the Coast Range and Cascade Mountains, and only a modest amount of snow in the Sierra Nevada. Officials say the snowpack is only 10 to 30 percent of normal levels. In addition, California's vital agricultural areas in the Sacramento and San Joaquin valleys, which lie west of the Sierra Nevada, are a parched brown. By contrast, a satellite image taken in January 2013 shows significant snowpack in the mountains and a swath of green in the Sacramento and San Joaquin Valleys. Half of California's yearly precipitation falls between December and February, so January's record dry conditions threaten water supplies for the entire year.

Pebble Mine Would Endanger
Alaska's Bristol Bay, Major EPA Study Finds
A three-year study by the U.S. Environmental Protection Agency (EPA) has determined that mining in Alaska's Bristol Bay area would pose significant dangers to the environment
, a potentially fatal setback for plans
Mulchatna River, part of Bristol Bay watershed
to develop Pebble Mine, a major open-pit mining project that aimed to exploit one of the largest and richest mineral deposits in the world. The EPA study cited concerns for the region's thriving sockeye salmon population
and its native people, saying the mine would destroy 24 to 94 miles of salmon streams and 1,300 to 5,350 acres of wetlands, ponds, and lakes. Pebble Mine proponents, including Alaska Governor Sean Parnell, criticize the study as flawed and rushed, since the development company wasn't allowed to submit its mining plan before the EPA study. Native groups, fishermen, and environmental organizations are applauding the study. The proposed mine — which seeks to exploit gold, copper, and other metals — was already in trouble, with one of two major partners withdrawing from the project last year.

Renewable Energy Comprised
Total U.S. November Power Generation Gains
All of the additional electricity-generating capacity added by the U.S. last month came from renewable energy sources, according to a report from the Federal Energy Regulatory Commission (FERC)
. Solar, biomass, wind, geothermal, and hydropower projects provided 394 megawatts — 100 percent — of all new electricity generation that went on line in November. No new capacity was added from fossil fuels or nuclear power, FERC reported. Renewable energy sources also provided 99 percent of all new electricity-generating capacity in October. Although natural gas has been the biggest player in added capacity so far this year (52 percent), solar also made gains. It alone has made up roughly 21 percent of new power capacity so far in 2013, two-thirds more than its year-to-date total in 2012. Renewable sources now account for 15.9 percent of total U.S. generating capacity, which is more than nuclear (9.2 percent) and oil (4.05 percent) combined.

Mapping Course and Software
Make Forest Monitoring Widely Accessible
Citizen scientists interested in tracking the health of the planet's forests have a new tool at their disposal. New software that uses satellite technology to map and
monitor changes in forested areas is being made available to the public
through a free online course. Users who complete the course, hosted by Stanford University
, can receive a license to operate the software, called CLASlite. CLASlite, or the Carnegie Landsat Analysis System lite, is a highly automated system for converting satellite imagery from its original, raw format into maps that can be used to detect deforestation, logging, and other disruptions. It was developed by Carnegie researcher Greg Asner to help governments, nongovernmental organizations, and academic institutions conduct high-resolution mapping and monitoring of forests
. "We are making the science of forest monitoring broadly available to people who want and need to participate in tracking and managing the health of their forests," said Asner.

A business competition at heart, Fish 2.0 brought together entrepreneurs and investors to spur innovation in the tradition-bound seafood industry. Competitors's proposals ranged from converting waste at fish processing plants to expanding a Hawaiian network of aquaponic growers, who raise fish and vegetables together in tanks, into the developing world. One proposal aimed to create a data system to track catches in real time, enabling fisheries managers to hold the line on harvests. Contestants headed home with more than $75,000 in prize money.

Interview: How Big Agriculture
Has Thwarted Factory Farm Reforms
In 2008, the Pew Commission on Industrial Farm Animal Production released a landmark report
that condemned the way the U.S. raised its cattle, pigs, and
chickens and made a sweeping series of recommendations on how to reduce the severe environmental and public health problems created by the current system. Last month, the Johns Hopkins Center for a Livable Future released a study
analyzing the fate of these reforms and reached a stark conclusion: The power of the industrial agriculture lobby had blunted nearly all attempts at change. In an interview with Yale Environment 360
, Robert Martin, co-author of the Johns Hopkins report, discusses what went wrong and how reforms can proceed. One hopeful sign, says Martin, is "there are more and more people who are concerned about where their food comes from and how it’s produced."Read the interview.

Groundbreaking Mapping Project
Depicts Forest Change Around the Globe
Scientists from Google, U.S. universities, and federal agencies have for the first time produced a high-resolution global map showing in striking detail the extent of deforestation across the globe.
The project — which relied heavily on expertise from the computing
center Google Earth Engine — documents a loss of 888,000 square miles of forest between 2000 and 2012, along with a gain of 309,000 square miles of new forest. The rate of deforestation is equal to losing 68,000 soccer fields of forest every day for the past 13 years, or 50 soccer fields every minute, says the World Resources Institute
. Brazil, once responsible for a majority of the world's tropical forest loss, is now the global leader in scaling back forest destruction, cutting its deforestation rate in half over the past decade, researchers report in Science
. Over the same period, Indonesia has more than doubled its annual rate of forest loss, despite a supposed 2011 Indonesian government moratorium on new logging licenses.

Treaties May Not Be The
Key to Global Sustainable Development
Sweeping international treaties are no longer the key for charting the planet’s path to sustainable development, according to international leaders gathered at the “Rio+20 to 2015” conference last week. Instead, they said, partnerships among governments, businesses, and NGOs hold the most promise for measurable progress on sustainability issues, including climate change. "There’s been an enormous focus on treaties," Hans Hoogeveen, director general of the Dutch Ministry of Economic Affairs, told the conference at Yale University. "Lawyers and diplomats think they can rule the world, govern the world, from New York, Nairobi, or Rome. I think we have to learn that this not reality anymore." The United Nations convened a summit in Rio in 2012 to secure sustainability commitments from private businesses, societal groups, and leaders at all levels of government. Last week’s conference sought to develop recommendations for producing timely, measurable results from those commitments before international talks planned for Paris in 2015.Read more

Austrian Team Wins U.S.
Department of Energy Solar Competition
Employing creative ventilation and natural wood, a team from Austria won the 2013 Solar Decathlon
, a biennial competition for solar houses sponsored by U.S.
Department of Energy. The winning design features large living spaces with natural ventilation that helps the house maintain comfortable temperature and humidity levels, and is 96 percent wood. "It was important to us to use wood, because we have a lot of forests in Austria," team member Philipp Klebert told Fast Co.Exist
. "We wanted to make a statement about sustainability in that respect." Floor-to-ceiling and wall-to-wall sliding-glass doors, combined with an open floor plan, cool the house quickly and with minimal energy consumption. Among other guidelines, all Solar Decathlon entries must produce as much solar energy as they consume, and houses are scored in 10 categories
ranging from affordability to home entertainment. One of the team's sponsors is planning to market the design, perhaps as a self-assembly kit, Fast Co.Exist reports.

month by the U.N. Intergovernmental Panel on Climate Change's assessment report on the physical effects of global warming, the researchers say. Sinking oxygen levels, which could decline by 1 to 7 percent by 2100, increasing ocean acidification, and overfishing of more than 70 percent of marine populations are among the biggest threats to ocean ecosystems, the scientists report in Marine Pollution Bulletin
. Mollusks and other sensitive organisms are increasingly being found with corroded shells, a result of rising dissolved CO2 concentrations; within 20 to 40 years ocean acidity levels may reach the point where coral reefs are eroded faster than they can regenerate, the review said.

Swapping Corn for Rice Benefits
China's Miyun Reservoir, Study Shows

, say researchers from China and the U.S. Rice farming had contaminated and tapped the reservoir, which lies 100 miles north of Beijing and is the main water source for the city's 20 million inhabitants. But four years ago, the Chinese government began paying farmers to grow corn instead, which requires less water and leads to less fertilizer and sediment runoff than rice farming
. Now, water quality tests show that fertilizer runoff declined sharply, the researchers found, and the amount of reservoir water available to Beijing and surrounding areas has increased. Farmers also made more money growing corn instead of rice and were able to spend less time tending their crops, the study concluded

Crop Pests Migrate Poleward
Due to Global Warming, Study Says
Global warming has been driving crop pests toward the North and South poles at a rate of 1.7 miles per year, according to new research from the U.K. Looking at the
Stem rust (Puccinia graminis fungus)
distribution of 612 crop pests over the past 50 years, the researchers found a strong correlation between warming global temperatures and increased ranges for the pests. “If crop pests continue to march polewards as the Earth warms, the combined effects of a growing world population and the increased loss of crops to pests will pose a serious threat to global food security,” said Daniel Bebber, a biologist at the University of Exeter who led the study published in Nature Climate Change
. Crop pests — which include insects as well as bacteria, fungi, viruses, and nematodes — destroy 10 to 16 percent of the world's crops each year, or enough food to feed nine percent of the population, scientists estimate.

Illegal Slash-and-Burn Fires
Are Causing Smog Problem in Indonesia
Skies above Indonesia have been blanketed with smog

The illegal fires decimate rainforests and peatlands and fill the air with lethal levels of smoke, as seen in this NASA satellite image taken on August 27. Indonesia's pollution index hit a record-high 401 earlier this month; any reading above 400 is considered life-threatening to the elderly and sick. Palm oil is the world's largest vegetable oil commodity

New Deep-Rooted Rice
Shows Greater Resistance to Drought
Japanese scientists say they have developed a rice plant with deeper roots
that could yield a more drought-resistant variety of rice. Writing in the journal Nature Genetics
, a team of scientists describes the discovery of gene that causes a rice strain known as Kinandang Patong, grown in the dry upland of the Philippines, to send longer roots into the soil, allowing the plant to extract water from deeper soil layers. After splicing the gene with a commonly grown rice strain, called IR64, the scientists found that the maximum root depths were more than twice those of the typical plants. After exposing both strains to moderate and severe drought conditions, the researchers found that yields of the standard variety fell significantly in moderate drought conditions and collapsed altogether in severe drought, while the modified strains were not affected by moderate drought and yields declined only 30 percent in severe drought.

Mapping of Oil Palm Genome
Could Boost Productivity of Key Crop
Scientists say they have identified the gene responsible for the yield of oil palm crops, a discovery that could boost the productivity of the world’s top source of

, Malaysian and U.S. researchers describe the mapping of the genome of the oil palm, whose products are used in everything from food to cosmetics to biofuels. According to the scientists, the so-called “shell gene” controls “how the thickness of its shell correlates to fruit size and oil yield
.” The fruit of the African palm oil tree comes in three varieties
: a thick-shelled dura, a shell-less pisifera, and a thin-shelled tenera, which produces a greater oil yield. According to scientists, the shell gene plays a key role in a mutation that produces the more commercially productive tenera variety.

European Fish Stocks
Show Signs of Recovery, Study Says
A major assessment of fish stocks in the northeast Atlantic Ocean shows that many species are recovering and are now being fished sustainably.
The surprising findings, reported in the journal Current Biology,
are based on data from government research institutes that collected millions of measurements of fish, both at sea and in markets. The study showed that for the first time in decades the majority of fish stocks in the northeast Atlantic are recovering, thanks to reforms instituted by individual nations and the European Union in 2002. This good news comes amid widespread criticism of EU fisheries policies
, which recently have undergone further reform. “We should be aware that low fishing pressure needs to be maintained until stocks recover,” said researcher Robin Cook of the University of Strathclyde in Scotland. “This is only the first step. Now we need to see numbers increase as a result of continued low fishing pressure.”

The plan, which was proposed by the U.S. and New Zealand, would have protected a total of 2.3 million square miles in the Ross Sea, a deep, high-latitude body of water in the Southern Ocean. But during a meeting of the 25-member Commission for Conservation of Antarctic Marine Living Resources, Russia questioned whether the organization had the legal right to create such a haven. A key sticking point for the Russians was the potential loss of the fishery for krill, a shrimp-like creature that is a critical food source for penguins, seabirds, seals, and whales, but is netted for use in Omega-3 dietary supplements.

‘Peak Oil’ Concerns Overstated
As Demand Will Fall, Study Predicts
Researchers say concerns that humanity will inevitably reach a moment of “peak oil,” which would be followed by a crippling decline in supplies, are unwarranted
because global demand for oil is approaching its own peak
. Writing in the journal Environmental Science & Technology
, researchers from Stanford University and the University of California-Santa Cruz (UCSC) say that dire projections of peak oil mistakenly assume that an increasingly wealthy planet will continue to rely heavily on oil. On the contrary, they say, the link between economic growth and oil is breaking down as a result of increased energy efficiency, lower prices for alternative fuel sources, urbanization, and limits on consumption by the wealthy. While the researchers project surging global demand for airline travel and various forms of freight transportation, there will be less reliance on oil, with conventional oil demand declining after 2035.
