underpinning world food production, according to
a new report by the United Nations Food and Agriculture Organization (FAO). Between 16 and 22 percent of current crop species — including 61 percent of peanut and 12 percent of potato species — could become extinct in the next 50 years, the report notes. Wild strains, which are often better at adapting to environmental changes, will become increasingly important
for feeding the global population, which is expected to grow by 3 billion people by 2050, the report says. Strengthening gene and seed banks, improving breeding practices, increasing genetic diversity on farms and in fields, and preserving soil microbiomes
will be key to boosting crops' climate resilience, the FAO said.

bulbs, the world’s largest street-lighting upgrade to date. The new lights, which will afford the city a 44-percent reduction in energy costs, will pay for themselves, according to Philips
, the company supplying the new system. In addition to drawing less overall power, the bulbs’ intensity will be controlled from a central command panel, resulting in less wasted energy. Of the 225,000 new lights, 84,000 will be locally manufactured LEDs, and the city is taking measures to ensure the safe recycling of heavy metals found in the old lamps. Similar, though smaller, projects have been undertaken in Argentina, Sweden, and the Netherlands.

Latin American and Caribbean
Nations Pledge Major Forest Restorations
Latin American and Caribbean countries yesterday launched Initiative 20x20
, an effort to begin restoring
Forest restoration commitments
20 million hectares of degraded land — an area larger than Uruguay — by 2020. The initiative has secured $365 million in funds, its leaders announced, which will be used to restore forests, avoid deforestation, and improve the use of trees and livestock in agriculture — practices known as agroforestry and silvopasture. This restoration is expected to provide extensive economic, social, and environmental benefits through improved local livelihoods and ecosystem services such as erosion prevention, water purification, and carbon storage, organizers say. Restoration commitments totaling just over 20 million hectares were announced yesterday, with Mexico and Peru making the largest pledges. The initiative was launched in Lima, Peru, alongside international climate talks.

Public Largely Unaware of Meat
And Dairy's Contribution to Climate Change
The general public has a major lack of understanding of how eating meat and dairy contributes to climate change,
Perceived vs. actual carbon emissions
according to a survey
of Europe, the Americas, Asia, and Africa by the market research organization Ipsos MORI. Although meat and dairy production accounts for roughly 15 percent of total global carbon emissions — equal to exhaust emissions from the international transportation sector — less than 30 percent of survey respondents identified meat and dairy production as a major contributor to climate change. More than twice as many — 64 percent — said transportation was a major contributor. Closing the awareness gap is essential for changing meat and dairy consumption patterns, researchers said, especially in developed nations such as the U.S. Although much of the projected increase in meat and dairy consumption will likely happen in emerging economies, respondents in Brazil, India, and China demonstrated greater consideration of climate change in their food choices and above-average willingness to modify their consumption — an encouraging sign, researchers said.

Old-Growth Forest in China
Shrinking Despite Protections, Study Says
China’s anti-logging, conservation, and ecotourism policies are actually accelerating the loss of old-growth forests
Deforestation in China's Yunnan Province.
in one of the country's most ecologically diverse regions, according to a study published in the journal Biological Conservation
. Researchers used satellite imagery and statistical analysis to evaluate forest conservation strategies in northwestern Yunnan Province, in southern China. The results show that a logging ban increased total forest cover but accelerated old-growth logging in ancient protected areas known as sacred forests. For centuries, sacred forests have effectively protected old-growth trees from clear-cutting, despite major upheavals in the region’s history. Recent environmental protection policies, however, have shifted management of these areas away from native communities to government agencies — apparently to the forests' detriment, the study shows.
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
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. Read more.
Interview: Saving World’s Oceans Begins With Coastal Communities
Aggressively curbing overfishing, pollution, and development is something coastal communities
can do immediately to protect their ocean resources — and with dramatic results — says marine biologist Ayana Elizabeth Johnson. As the executive director of the Waitt Institute
, an ocean conservation organization, Johnson recently put that approach to the test on the Caribbean island of Barbuda. In an interview with Yale Environment 360
, she discusses how she helped Barbuda craft rules to protect its ocean resources and why she favors community-driven conservation efforts over more top-down approaches.

Half of the Planet's
Animals Lost Since 1970, Report Says
The number of animals on the planet has fallen 52 percent in the last 40 years, according to an analysis
Animal population trend since 1970
the conservation organization World Wildlife Fund (WWF). The group's Living Planet Index, which tracked the populations of more than 10,000 vertebrate species from 1970 to 2010, revealed major declines in key populations of mammals, birds, reptiles, amphibians, and fish. The situation is most dire in developing countries, the report said, where wildlife populations have fallen on average by 58 percent. Latin America saw the biggest declines, with more than 80 percent of the region's animals lost since 1970. Globally, freshwater populations have plummeted 76 percent. This year's numbers are worse than those calculated in the last report in 2012, which found declines of 30 percent since 1970. The organization attributed this to new statistical weighting, which it said better represents each region's biodiversity, though other researchers have been critical
of the new methodology. Habitat loss and degradation was cited as the primary cause of biodiversity loss.

Nations Announce Agreement
To End Forest Loss by 2030 at UN Summit
The U.S., Canada, and the European Union agreed at yesterday's UN climate summit to cut global
Deforestation for palm oil in Malaysian Borneo
deforestation in half by the end of the decade and eliminate net forest losses entirely by 2030, marking the first time such a deadline has been set. If the goal is met, it will cut carbon emissions by an amount equal to taking 1 billion vehicles — every car on the planet — off the road, the UN said
. Notably missing from the list of committed countries was Brazil, which has been a key player in Amazon deforestation, because of concerns that the pledge would clash with national laws permitting managed deforestation. Critics say ending deforestation is nearly impossible without Brazil's cooperation. In addition to the 32 national governments that signed onto the declaration, 35 corporations, including Kellogg's, L'Oreal, and Nestle, pledged to support sustainable forest practices in their supply chains.

Global Population on Track to
Reach 11 Billion by 2100, Researchers Say
A new analysis of United Nations global population data finds an 80-percent probability that the number of
people in the world, now 7.2 billion, will increase to between 9.6 and 12.3 billion in 2100. Published in the journal Science
, the study counters the widely accepted projection that global population will peak at roughly 9 billion by 2050, then gradually decline. The new study instead finds a 70-percent likelihood that population will grow continuously throughout the century to reach 10.9 billion by 2100. Researchers attribute the higher projections, in part, to increasing fertility rates in sub-Saharan Africa, where population growth had been predicted to continue slowing. The Guardian
notes that many widely cited global policy assessments, such as recommendations from the Intergovernmental Panel on Climate Change, assume a population peak by 2050.

Shift to Mass Transit Could
Have Major Economic and Climate Benefits
Expanding public transportation and infrastructure that promotes walking and biking throughout the world's
cities could save $100 trillion and cut transportation-related carbon emissions by 40 percent by 2050, according to
an analysis by researchers at the University of California, Davis, and the Institute for Transportation and Development Policy. Urban transportation-related emissions could double by 2050 as growth continues in major cities in China, India, and other developing countries. But if China alone were to develop extensive bus rapid transit and commuter transit networks, its predicted transportation-related emissions in 2050 could be cut by 40 percent, the analysis found. The U.S. — currently the world's largest contributor to urban transportation-related emissions — is seeing declines in that sector as population growth slows, vehicle fuel efficiency improves, and people drive less. But those emissions cuts could accelerate sharply if urban mass transit were improved, the report said.
Interview: Making Farm-to-Table
A Truly Sustainable Movement
Renowned chef Dan Barber is synonymous with the farm-to-table movement. His two New York restaurants
feature organic ingredients grown or raised on nearby farms, including the one that surrounds his Hudson Valley restaurant. So it’s striking that in his new book, The Third Plate
, Barber maintains that the movement he has been championing hasn’t gone far enough. In an interview
with Yale Environment 360
, Barber says if the farm-to-table movement is to truly support sustainability, end the rise of monocultures, and produce delicious food, it’s the table that must support the farm, not the other way around. And that, he says, calls for a new way of cooking and eating. Read the interview | Listen to a podcast

U.S. Dietary Guidelines Would
Lead to Rise in Emissions, Study Says
Following U.S. federal guidelines for a healthy diet is likely to increase greenhouse gas emissions, even though the guidelines recommend a diet with less meat than the average American currently consumes, according to a recent analysis in the Journal of Industrial Ecology
. Compared to U.S. Department of Agriculture dietary guidelines, American's don't eat enough fruits, vegetables, seafood, and dairy, and they consume too much meat, eggs, nuts, soy, oils, solid fats, and added sugars. If the population were to shift its diet to match USDA guidelines, greenhouse gas emissions would actually rise by 12 percent, researchers found, because calories from meat, eggs, fats, and sugars would largely be replaced by dairy products. Methane emissions
from dairy and beef cattle contribute significantly to atmospheric greenhouse gas levels. The findings highlight a need to consider both environmental and health objectives when making dietary recommendations, the researchers say.

Six Strategies Could End
Global Water Stress by 2050, Scientists Say
Global water stress could be alleviated by the year 2050 if countries work to implement six key strategies
ranging from building more reservoirs to controlling population growth, according to
research from Canada and the Netherlands. Water stress is defined as occurring when more than 40 percent of the water from a region's rivers is unavailable because it is already being used — a situation that currently affects roughly one-third of the global population. Writing in Nature Geoscience
, the scientists propose six steps they believe can help reduce water stress: planting crops that use water and nutrients more efficiently; using more efficient irrigation methods; improving the efficiency of water use in homes, industry, and municipalities; limiting the rate of population growth so global population stays below 8.5 billion by 2050; increasing reservoir water storage capacity; and intensifying water desalination operations

Meat Production, Especially
Beef, Strains Land and Water, Study Says
Global meat production has expanded more than four-fold over the last 50 years — and 25-fold since
Beef cattle graze in Colombia
1800 — due to growing purchasing power, urbanization, and changing diets, according to a new report from the Worldwatch Institute
. Consumers in industrial countries still eat much larger quantities of meat (75.9 kilograms per person) than those in developing nations (33.7 kilograms), though that gap is beginning to close, the report says. Nearly 70 percent of the planet's agricultural land and freshwater is used for livestock, with additional land and water used to grow grains for livestock feed. Beef production alone uses about three-fifths of global farmland and yields less than 5 percent of the world's protein, according to the report. Sustainable agricultural practices
such as feeding livestock with grasses instead of grains and using natural fertilizers could reduce these impacts, the report notes, but alternative dietary choices hold the most immediate promise for reducing the environmental footprint of meat production.

New Citizen Science Software
Aims to Document and Curb Illegal Fishing
Citizen scientists can now report — and potentially help stop — illegal fishing
with the snap of a photo thanks to
Illegal shark fin catch
a new smartphone app developed by the Nature Conservancy. The software, called ShipWatch
, was developed this summer during a "Fishackathon," a series of workshops hosted by the U.S. State Department to foster technology development and collaboration among computer programmers. ShipWatch allows users to upload photos of illegal fishing activities to a database, where they are labeled with date and location information and plotted on a central map. The developers hope the data will help authorities enforce existing fishing laws by, for example, developing flight maps for surveillance drones or strategically deploying enforcement authorities. "There are laws in place to say [the fishing] is illegal. The problem is they lack any kind of reporting mechanism," developers told Fast Co.Exist.

reducing CO2 emissions from deforestation, according to a new report
. The World Resources Institute
(WRI) and the Rights and Resources Initiative
said that indigenous people and rural inhabitants in Latin America, Africa, and Asia have government-recognized rights to forests containing nearly 38 billion tons of carbon, equal to 29 times the annual emissions of all the world’s passenger vehicles. By enforcing community rights to those forests
, the study said, governments can play a major role in tackling climate change. In the Brazilian Amazon, for example, deforestation rates are 11 times lower in community forests than in forests outside those areas. In areas where community forest rights are ignored, deforestation rates often soar. The report made five major recommendations, from better enforcement of community forest zones to compensating communities for the benefits their forests provide.

"Inglorious" Produce Campaign
Is Major Success for French Grocer
A major French grocery chain, Intermarche, has launched a novel campaign
to curb food waste
market visually flawed produce. The "Inglorious Fruits and Vegetables" campaign aims to revamp the image of imperfect and non-conforming produce, much of which is thrown away by growers because it doesn't meet grocery retailers' standards. Intermarche began welcoming the "Grotesque Apple," "Ridiculous Potato," "Hideous Orange," and other infamous items to its shelves, created posters to explain that the produce is as nutritious and flavorful as the more attractive versions, and reduced prices by 30 percent. The campaign was an "immediate success

California Agriculture Relying
Too Heavily on Groundwater in Drought
California's agriculture industry is relying too heavily on groundwater to irrigate drought-stricken farmlands — a trend that will not be sustainable long-term, according
Central Valley orchard
to a study
by the University of California, Davis. The drought, which is the third most severe on record, is responsible for the greatest water loss ever seen in California agriculture, with river water for Central Valley farms reduced by roughly one-third, the study found. Groundwater pumping will likely replace most river water losses, and some areas have more than doubled their pumping rate over the previous year. If the drought continues for two more years, the report says, groundwater reserves will continue to be depleted to replace surface water losses and pumping ability will slowly decrease, which could affect crop production. So far in the current drought, 428,000 acres of cropland — roughly 5 percent — has been made fallow across the Central Valley, Central Coast, and Southern California.

One-third of German Power
Came from Renewables in First Half of 2014
Thanks to abundant sunshine and wind, renewable energy generated 31 percent of Germany’s electricity
in the first six months of this year, according to a new report. The report
, released by the Fraunhofer Insititute, said that 27 percent of the country’s electricity production came from wind and solar, and four percent from hydropower. Solar power generation grew by 28 percent in the first half of 2014 compared to the first six months of 2013, and wind power grew by 19 percent over the same period. On a couple of particularly windy and sunny days in May and June, renewable energy accounted for 50 to 75 percent of Germany’s electricity production, the report said. The Fraunhofer Institute said that as Germany continues to phase out its nuclear power plants, it remains reliant on highly polluting “brown coal”
to produce electricity. A substantial portion of German coal-generated electricity is being exported, the report said.

country has taken such actions as a defense against climate change, the Guardian reports
. Kiribati, home to 110,000 people scattered across 33 islands in the Pacific Ocean, is one of several small island nations in the Pacific and Indian oceans that could be extensively or completely submerged within a few decades. The cost of protecting such countries often far outweighs their national incomes. Kiribati, with a GDP of under $200 million, ranks among the 10 countries facing the most severe financial impacts of climate change. The tract of 20 square kilometers on the island of Vanua Levu, Fiji, could provide a future refuge for all of Kiribati's citizens, the nation's president said.

Going Vegetarian Could Halve
A Consumer’s Food-related CO2 Footprint
A new study of more than 50,000 people in the United Kingdom shows that going vegan, vegetarian, or even “pescatarian” can drastically reduce
people’s carbon footprints. Published in the journal Climatic Change
, the study concluded that if people eating more than 100 grams of meat a day went vegan, their food-related carbon footprint would shrink by 60 percent. If a person eating more than 100 grams of meat per day — and U.S. consumers eat about 225 grams daily — cut down to 50 grams per day, their food-related CO2 emissions would fall by a third, the study said. Pescatarians, who eat fish but no other meat, generate only 2.5 percent more CO2 emissions than vegetarians, according to the study. The research also concluded that vegans produce 25 percent fewer CO2 emissions than vegetarians, who still eat eggs and dairy. “In general there is a clear and strong trend with reduced greenhouse gas emissions in diets that contain less meat,” said Oxford University researcher Peter Scarborough, a co-author of the study.

Brazil Leads the World
In Cutting Deforestation, Analysis Finds
Brazil has become the world leader in reducing deforestation and, at the same time, has increased its soy and beef production, researchers report
Amazon rainforest near Manaus, Brazil
. The country has cut its forest loss by 70 percent since 2004, sparing more than 86,000 square kilometers of rainforests and keeping more than 3.2 billion tons of carbon dioxide out of the atmosphere. Brazil's decline in deforestation in 2013 alone represented a 1.5 percent reduction in global emissions that year, the report says; globally, tropical forest loss
accounts for 15 percent of global carbon dioxide emissions. The analysis credits the success to bold government policies, pressure from environmental groups, and market fluctuations in the price of soy and beef, but the authors warn that these wins may be short-lived without more positive incentives for farmers. “These gains are globally significant, but fragile,” one researcher explained. “We’re bumping up against the limits of what can be achieved through punitive measures.”

Electric Airplane Debut
Offers Hopes for Cutting Emissions
The aircraft manufacturing giant Airbus recently unveiled
a fully-electric aircraft which, if widely adopted, could reduce the aerospace industry's carbon

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.

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.

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.”
