New Study: Climate Change Threatens World's Wheat Crop

A study released Sunday afternoon finds that wheat crop yields could plunge due, in part, to climate change. The study, published in Nature Climate Change, researchers warn that current projections underestimate the extent to which hotter weather in the future will accelerate this process. Extreme heat causes wheat crops to age faster and reduce yields, the Stanford University-led study shows, underscoring the challenge of feeding a rapidly growing population as the world continues to warm.

New Scientist magazine reported Sunday:

It could be much more difficult than we thought to feed everyone in a warmer world. Satellite images of northern India have revealed that extreme temperatures are cutting wheat yields. What's more, models used to predict the effects of global warming on food supply may have underestimated the problem by a third.

András Székács and Béla Darvas - Forty Years with Glyphosate

EXTRACT:

6. Adverse environmental effects of glyphosate

6.1 Glyphosate and Fusarium species

Sanogo and co-workers (2000) observed that crop loss in soy due to infestation by Fusarium solani f. sp. glycines increased after glyphosate applications. 

Kremer and co-workers (2005) described a stimulating effect of the root exsudate of GR soy sampled after glyphosate application on the growth of Fusarium sp. strains. Treatments caused concentration dependent increase on the mycelium mass of the fungus. Nonetheless, Powel and Swanton (2008) could not confirm these observations in their field study. 

Kremer and Means (2009) claim that certain fungi utilise glyphosate released from plant roots into the soil as a nutritive, which facilitates their growth. Soil manganese content also affects the above consequence of glyphosate through chelating with the compound and thus, modifying its effects. Considering the fact that numerous plant pathogenic Fusarium species produce mycotoxins, an increasing proportion of these species is far not favourable as a side-effect.András Székács and Béla Darvas - Forty Years with Glyphosate

Tom Philpott - USDA Greenlights Monsanto's Utterly Useless New GMO Corn

You've got to keep an eye on US regulatory agencies in the second half of December. That's when watchdog journalists like me tend to take time off—and regulators like to sneak gifts to the industries they're supposed to be regulating. This year, I was alert enough to detect this gift from the FDA to the meat industry; but the USDA caught me napping. The agency made two momentous announcements on GMO crops, neither of which got much media scrutiny. It deregulated Monsanto's so-called drought-tolerant corn, and it prepared to deregulate Dow's corn engineered to withstand the herbicides 2,4-D and dicamba. More on the later this week. 

The drought-tolerant corn decision, which came down on Dec. 21, was momentous occasion, because it marked the first deregulation of a GMO crop with a "complex" trait. What I mean by that is, the other GMOs on the market have simple, one-gene traits: a gene that confers resistance to a particular herbicide, like Monsanto's Roundup Ready seed or a gene that expresses the toxic-to-bugs properties of the bacteria Bt, as in Monsanto's Bt seed. But a plant's use of water is a complex process involving several genes; there's no single "drought tolerant" gene. Generating such traits in plants that succeed in field conditions has been considerably more tricky for the agrichemical giants than than simple traits.

Big Agribusiness Influence Threatens to Override Public Interest in Greed Revolution

A new 30-page report that documents the growing influence of agribusiness on the multilateral food system and the lack of transparency in research funding has been released today by the international civil society organization ETC Group. The Greed Revolution: Mega Foundations, Agribusiness Muscle In On Public Goods presents three case studies – one involving the UN Food and Agriculture Organization (FAO) and two involving CGIAR Centers (Consultative Group on International Agricultural Research) – which point to a dangerous trend that will worsen rather than solve the problem of global hunger. The report details the involvement of, among others, Nestlé, Heineken, Monsanto, the Bill & Melinda Gates Foundation and Syngenta Foundation.

"It is unacceptable that the UN is giving multinational agribusiness privileged access to alter their agricultural policies, said Pat Mooney, Executive Director of ETC Group, who has been involved in the field for 40 years. "It is ridiculous that the key organizations responsible for agricultural research have no credible data on the extent of corporate involvement in their work and that CGIAR's biggest funder – at $89 million – is somebody called, 'Miscellaneous!' Governments and UN secretariats have forgotten that their first task is to serve the public – not the profiteers."

Jayati Ghosh - Could Ecuador be the most radical and exciting place on Earth?

Ecuador must be one of the most exciting places on Earth right now, in terms of working towards a new development paradigm. It shows how much can be achieved with political will, even in uncertain economic times.

Just 10 years ago, Ecuador was more or less a basket case, a quintessential "banana republic" (it happens to be the world's largest exporter of bananas), characterised by political instability, inequality, a poorly-performing economy, and the ever-looming impact of the US on its domestic politics.

In 2000, in response to hyperinflation and balance of payments problems, the government dollarised the economy, replacing the sucre with the US currency as legal tender. This subdued inflation, but it did nothing to address the core economic problems, and further constrained the domestic policy space.

Genetically modified mosquitoes' survival rate concealed

A confidential internal document obtained by civil society groups shows genetically modified mosquitoes described by their manufacturer, UK company Oxitec, as “sterile” are in fact not sterile and their offspring have a 15 percent survival rate in the presence of the common antibiotic tetracycline.

In the study described in this document, the genetically modified mosquitoes were fed cat food containing chicken contaminated with low levels of tetracycline and many of the mosquitoes were able to reproduce, with their offspring surviving to adulthood (1).

A redacted version of the document, released to GeneWatch UK under freedom of information laws, shows that the company tried to hide the evidence that its technology will fail to prevent reproduction in the presence of low levels of tetracycline contamination (2).

Tom Philpott - Are Pesticides Behind Massive Bee Die-Offs?

For the German chemical giant Bayer, neonicotinoid pesticides—synthetic derivatives of nicotine that attack insects' nervous systems—are big business. In 2010, the company reeled in 789 million euros (more than $1 billion) in revenue from its flagship neonic products imidacloprid and clothianidin. The company's latest quarterly report shows that its "seed treatment" segment—the one that includes neonics—is booming. In the quarter that ended on September 30, sales for the company's seed treatments jumped 28 percent compared to the same period the previous year.

Such results no doubt bring cheer to Bayer's shareholders. But for honeybees—whose population has come under severe pressure from a mysterious condition called colony collapse disorder—the news is decidedly less welcome. A year ago on Grist, I told the story of how this class of pesticides had gained approval from the EPA in a twisted process based on deeply flawed (by the EPA's own account) Bayer-funded science. A little later, I reported that research by the USDA's top bee scientist, Jeff Pettis, suggests that even tiny exposure to neonics can seriously harm honeybees.

Now a study from Purdue University researchers casts further suspicion on Bayer's money-minting concoctions. To understand the new paper—published in the peer-reviewed journal Plos One—it's important to know how seed treatments work, which is like this: The pesticides are applied directly to seeds before planting, and then get absorbed by the plant's vascular system. They are "expressed" in the pollen and nectar, where they attack the nervous systems of insects. Bayer targeted its treatments at the most prolific US crop—corn—and since 2003, corn farmers have been blanketing millions of acres of farmland with neonic-treated seeds.

David Atkins - More proof the system is broken, bee colony collapse edition

That the panicked news stories about it have died down doesn\'t mean that the honeybee die-offs due to "colony collapse disorder" have gone away. It\'s still happening with a vengeance, and it\'s almost certain that pesticides are to blame:

Although news about Colony Collapse Disorder (CCD) has died down, commercial beekeepers have seen average population losses of about 30 percent each year since 2006, said Paul Towers, of the Pesticide Action Network. Towers was one of the organizers of a conference that brought together beekeepers and environmental groups this week to tackle the challenges facing the beekeeping industry and the agricultural economy by proxy.

"We are inching our way toward a critical tipping point," said Steve Ellis, secretary of the National Honey Bee Advisory Board (NHBAB) and a beekeeper for 35 years. Last year he had so many abnormal bee die-offs that he\'ll qualify for disaster relief from the U.S. Department of Agriculture (USDA).
In addition to continued reports of CCD -- a still somewhat mysterious phenomenon in which entire bee colonies literally disappear, alien-abduction style, leaving not even their dead bodies behind -- bee populations are suffering poor health in general, and experiencing shorter life spans and diminished vitality. And while parasites, pathogens, and habitat loss can deal blows to bee health, research increasingly points to pesticides as the primary culprit.

Jill Richardson - We've Lost Nearly All of Our Wild Foods -- What Happened? And What Are We Missing?


A few days from now, a single bluefin tuna will make international headlines when it sells for an ungodly amount of money -- perhaps more than $100,000 -- at Tokyo's Tsukiji market. And while the high price of the first bluefin of the year will be extraordinary, the rarity, and thus the prestige and high pricetag of bluefin in general, provides a clue to humans' dietary history. Once upon a time, wild foods were a regular and beloved part of the American diet. Today, the American epicure might dine on foraged mushrooms and ramps, but for many of us, fish are the last wild food we eat. What happened? And what are we missing?

Georgia Pellegrini, a chef who has worked in elite restaurants in New York and France, decided to answer this question for herself when she set out to hunt her own food. As her new book's title implies -- Girl Hunter: Revolutionizing the Way We Eat, One Hunt at a Time -- she entered into a masculine realm in which she was often the only woman. Pellegrini traveled across the United States and even England, hunting everything from squirrel to elk. As much as she stands out as a woman, she also stands out among the local and sustainable food movement. (An anthropologist recently pointed out that the local food movement "has been reticent to embrace hunting as an integral part of sustainable eating.")

As a chef, Pellegrini focuses on her meal's flavor more than many other sustainable food writers. At one point, while contemplating pulling the trigger to shoot a javelina, Pellegrini says, "I wonder if I had to work hard enough for this. I wonder if I had to exert myself enough... Then I wonder how javelina taste."

The Guardian UK - The speculative scrum driving up food prices

The Guardian UK, December 21, 2011

http://www.guardian.co.uk/global-development/poverty-matters/2011/dec/20/speculative-scrum-driving-food-prices

Last year, the price of global food floated high as ever. That's bad news for most of us, but not for those who trade commodities. In fact, 2011 was a great year for the traders, who thrive on bad news, currency woes, drought, flood, freeze, fire and all other manifestations of imminent apocalypse.

2011 was a wild ride. One spring morning, cocoa futures dropped 12% in less than a minute. Corn ascended to all-time peaks and sugar fluctuated more in one day than it used to in a month. Howard Schultz, CEO of Starbucks, railed against speculators in coffee, while PepsiCo forecast its own medium-term commodity cost increases to exceed $1bn. All of which meant a bumper crop for the world's commodity exchanges – even those that used to be backwaters, like the Kansas City Board of Trade and the Minneapolis Grain Exchange, both of which recorded their highest electronic trading volumes in history.

It was a volatile year, and the volatility posed problems for the food industry. Faced with a high-stakes game of price-shifting basic ingredients, the world's largest food processors and retailers put out the call for maths PhDs and economic modellers to theorise and implement ever-more complex risk-management strategies just so they could keep up with the second-by-second spikes and dips of grain and livestock futures. In the meantime, high-frequency traders and momentum-driven hedge funds made it their business to speculate on food.

There were plenty of ways to get in on the action, but as an increasingly complex amalgam of food-based commodity derivatives piled one on top of the other, the more difficult it became to perceive what it was that lay at the bottom of the speculative scrum. What drove the global food market in 2011 – other than those old faithfuls, fear and greed? I put in a call toProfessor Yaneer Bar-Yam, of the New England Complex Systems Institute (Necsi), to see if he might have an answer.

GMW - Indian farm suicides - key facts and figures

Thanks to Aruna Rodrigues for the following information based on the research of P Sainath, the renowned Indian writer on the country's rural poor.

The National Crime Records Bureau's all-India figure for farm suicides 1995-2010 is 256,913.

First 8 years 1995-2002: 121,157 farm suicides

Second 8 years 2003-10: 135,756 farm suicides

Pawar, Agriculture Minister's home state of Maharashtra [where Bt cotton has had a huge uptake] has by far the worst record in the country with 50,481 farm suicides between 1995-2010. That is, 1995-2002: 20,066 and for 2003-10 [the period in which Bt cotton has been cultivated]: 30,415

Main points:

*The last 8 years were significantly worse with an annual average of 1832 farm suicides, higher than the first 8 years.

ScienceDaily - Global Forests Are Overlooked as Water Suppliers, Study Shows

http://www.sciencedaily.com/releases/2011/12/111215094923.htm

 

ScienceDaily (Dec. 15, 2011) — The forests of the world supply a significant amount of moisture that creates rain. A new study published in Global Change Biology reveals how this important contribution of forests to the hydrologic cycle is often overlooked in water resource policy, such as that of the EU.

The study, by David Ellison, Martyn Futter and Kevin Bishop at the Swedish University of Agricultural Sciences (SLU), shows that reducing forest area reduces regional and continental rainfall. This needs to be recognized to obtain a fair picture of the forest role in the hydrologic cycle.

"Are forests good for water? An apparently simple question divides scientists in two camps -- those who see trees as demanding water and those who see trees as supplying water," said David Ellison who works in the Future Forests research program studying resource management. "This paper demonstrates that the difference between these two camps has to do with the spatial scale being considered."

Claire Provost - Rush for Land a Wake-Up Call for Poorer Countries, Report Says

Published on Wednesday, December 14, 2011 by The Guardian/UK

http://www.guardian.co.uk/global-development/2011/dec/14/rush-for-land-gobal-south

by Claire Provost

Population growth, the increasing consumption of a global elite, and an international legal system skewed in favour of largescale investors are fuelling a worldwide rush for land that is unfolding faster than previously thought and is likely to continue, according to the largest study of international land deals to date.

Researchers estimate that more than 200m hectares of land – over eight times the size of the UK – have been sold or leased between 2000 and 2010. But although the food price crisis of 2007-08 may have triggered a boom in international land deals, the study argues that a much broader set of factors – linked to population growth and the rise of emerging economies – is raising the prospect of "a new era in the struggle for, and control over, land in many areas of the global south".

Forty civil society and research groups fed into the global commercial pressures on land research project, co-ordinated by the International Land Coalition (ILC), which draws on a decade of data to identify and analyse trends in large land acquisitions, and highlights the role of governments in brokering deals that may marginalise rural communities and jeopardise the future of family farming in favour of big industrial projects. This is the most comprehensive study to date of international land deals, pulling together findings from investigations around the world.

American Society for Horticultural Science - Blue light irradiation promotes growth, increases antioxidants in lettuce seedlings

Public release date: 12-Dec-2011

Treated seedlings are healthier, more vigorous after transplanting

ABIKO, JAPAN—The quality of agricultural seedlings is important to crop growth and yield after transplantation. Good quality seedlings exhibit characteristics such as thick stems, thick leaves, dark green leaves, and large white roots. Scientists have long known that plant development and physiology are strongly influenced by the light spectrum, which affects seedling structure. Raising seedlings irradiated with blue light has been shown to increase crop yield after planting because of the high accumulation of phenolic compounds. Although most studies with blue light only or blue mixed with red light have indicated that blue light-containing irradiation produces higher plant biomass, recent research has suggested that yield and crop quality could be improved by controlling light quality.

Researchers from Japan's Central Research Institute of Electric Power Industry premiered a study in HortScience that determined the effects of raising seedlings with different light spectra—such as with blue, red, and blue + red LED lights—on seedling quality and yield of red leaf lettuce plants. Photosynthetic pigments, polyphenols, and antioxidant activity of lettuce seedlings treated with different light spectra were also determined.

Stephen Leahy - Indigenous Peoples Call for REDD Moratorium

Published on Monday, December 12, 2011 by Tierramérica / Inter Press Service

http://www.commondreams.org/headline/2011/12/12-8

by Stephen Leahy

DURBAN, South Africa - A new coalition of indigenous peoples and local communities called for a moratorium on Reducing Emissions from Deforestation and Forest Degradation (REDD) programs, a key part of the negotiations for a new international climate treaty that took place over the last two weeks in South Africa.

According to the United Nations, REDD is an effort to create a financial value for the carbon stored in forests, offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development. REDD+ goes beyond deforestation and forest degradation, and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks. But, say indigenous and climate activists,"This is not a solution to climate change. The same extractive industries are involved and it allows them to continue raping Mother Earth." (Credit: World Rainforest Movement | www.wrm.org.uy) The new Global Alliance of Indigenous Peoples and Local Communities against REDD and for Life issued a statement stating that based on "in-depth investigations, a growing number of recent reports provide evidence that indigenous peoples are being subjected to violations of their rights as a result of the implementation of REDD+-type programs and policies."

Mike Ludwig - Under Industry Pressure, USDA Works to Speed Approval of Monsanto's Genetically Engineered Crops

Monday 12 December 2011

by: Mike Ludwig, Truthout | Report

http://www.truth-out.org/under-industry-pressure-usda-works-speed-approval-monsantos-genetically-engineered-crops/1323453319

For years, biotech agriculture opponents have accused regulators of working too closely with big biotech firms when deregulating genetically engineered (GE) crops. Now, their worst fears could be coming true: under a new two-year pilot program at the USDA, regulators are training the world's biggest biotech firms, including Monsanto, BASF and Syngenta, to conduct environmental reviews of their own transgenic seed products as part of the government's deregulation process.

This would eliminate a critical level of oversight for the production of GE crops. Regulators are also testing new cost-sharing agreements that allow biotech firms to help pay private contractors to prepare mandatory environmental statements on GE plants the United States Department of Agriculture (USDA) is considering deregulating. 

The USDA launched the pilot project in April and, in November, the USDA announced vague plans [3] to "streamline" the deregulation petition process for GE organisms. A USDA spokesperson said the streamlining effort is not part of the pilot project, but both efforts appear to address a backlog of pending GE crop deregulation petitions that has angered big biotech firms seeking to rollout new products.

Documents obtained by Truthout from a Freedom Of Information Act (FOIA) request reveal that biotech companies, lawmakers and industry groups have put mounting pressure on the USDA in recent years to speed up the petition process, limit environmental impact assessments and approve more GE crops. One group went as far as sending USDA Secretary Tom Vilsack a timeline of GE soybean development that reads like a deregulation wish list.

Isaiah Esipisu - Saving the Forests with Indigenous Knowledge

By Isaiah Esipisu*


DURBAN, South Africa, Dec 9, 2011 (IPS) - For the Laibon community, a sub-tribe of Kenya’s Maasai ethnic group, the 33,000-hectare Loita Forest in the country’s Rift Valley Province is more than just a forest. It is a shrine.

"It is our shrine. Our Gods live there. We gather herbs from the place. We use it for bee- keeping. It therefore forms part of our livelihood," said Olonana Ole Pulei, who is in Durban, South Africa, to represent his community at the ongoing 17th Conference of Partiesunder the United Nations Framework Convention on Climate Change. 

According to Nigel Crawhall, the Director of Secretariat for the Indigenous Peoples of Africa Co-ordinating Committee (IPACC), different African communities have incredible indigenous knowledge that they use in the conservation of forests and biodiversity in general, and this should be recognised during the negotiations in Durban. 

"Different communities have different practices that they use in forestry conservation," he said. 

Crawhall gave an example of how the Bambuti and Batwa pygmy communities, in the eastern Democratic Republic of Congo, conserved the forest using traditional methods. Both communities depend on the biodiversity of animal life in the equatorial forests in order to survive.

TerraDaily - Brazil says Amazon deforestation down to lowest level

by Staff Writers, TerraDaily.com
Brasilia (AFP) Dec 5, 2011

http://www.terradaily.com/reports/Brazil_says_Amazon_deforestation_down_to_lowest_level_999.html

Brazil said Monday that the pace of deforestation in its Amazon region fell to its lowest level since authorities began monitoring the world's largest tropical rainforest.

The head of the National Institute of Space Research (INPE), Gilberto Camara, said deforestation dropped to 6,238 square kilometers (2,408 square miles), between August 2010 and July this year, down 11 percent compared with the same period in 2009-20100.

"It's the lowest deforestation rate measured since INPE began its monitoring in 1988," Camara told a press conference.

"It's a great victory for Brazil. It's the lowest deforestation rate. The Amazon is a great instrument for carbon sequestration," one of the tools to combat global warming, said Aloizio Mercadante, the minister of science and technology.

Still, the area deforested in the year ending in July is four times the size of Sao Paulo, Brazil's largest city, according to the state Agencia Brasil.

Between August 2009 and July 2010, the Brazilian Amazon lost 7,000 square kilometers (2,700 square miles) of rain forest, until then the smallest loss recorded.

Deforestation in the Brazilian Amazon reached a historic peak of 27,700 square kilometers (10,700 square miles) in 2003-2004.

Monday's announcement came a day before the Brazilian Senate was due to adopt a reform of forestry legislation which could reduce the protected area.

The bill, which would have to be approved by the Chamber of Deputies, has the backing of Brazil's powerful agribusiness sector.

The current forestry code, which dates back to 1965, limits the use of lands for farming and mandates that up to 80 percent of the Amazon remain intact.

Authorities say key reasons for Amazon deforestation are fires, the advance of agriculture and stockbreeding and illegal trafficking in timber and minerals.

*The largest producer of transgenic seeds in the world is leasing some of the best agricultural lands on the Island [of Puerto Rico] with a pattern of questionable legality, while receiving incentives from the Fortuño administration.

When environmentalist Juan Rosario traveled to an Amish religious community in Iowa, to learn to make compost, he was surprised that they had a laboratory and the services of an expert in chemistry. What was a scientist doing in a place where people live far from technology and practice ecological farming with the simplest of methods?

An Amish dressed in their style, with a wide-brimmed black hat, white shirt, and black pants and black jacket, pointed toward a large cornfield on a nearby farm. "The scientist helps us verify that pollen from genetically modified corn does not contaminate our crops," he told Juan Rosario. "It's the same corn that you develop in Salinas."

Science Daily - Evidence Supports Ban On Growth Promotion Use of Antibiotics in Farming

http://www.sciencedaily.com/releases/2011/11/111115103514.htm

 

ScienceDaily (Nov. 15, 2011) — In a review study, researchers from Tufts University School of Medicine zero in on the controversial, non-therapeutic use of antibiotics in food animals and fish farming as a cause of antibiotic resistance. They report that the preponderance of evidence argues for stricter regulation of the practice. Stuart Levy, an expert in antibiotic resistance, notes that a guiding tenet of public health, the precautionary principle, requires that steps be taken to avoid harm.

"The United States lags behind its European counterparts in establishing a ban on the use of antibiotics for growth promotion. For years it was believed that giving low-dose antibiotics via feed to promote growth in cows, swine, chickens and the use of antibiotics in fish farming had no negative consequences. Today, there is overwhelming evidence that non-therapeutic use of antibiotics contributes to antibiotic resistance, even if we do not understand all the mechanisms in the genetic transmission chain," says Levy, MD, professor of molecular biology and microbiology and director of the Center for Adaptation Genetics and Drug Resistance at Tufts University School of Medicine.

For the past 70 years, humans have relied on antibiotics to combat bacterial infections such as streptococcus, meningitis, tuberculosis and urinary tract infections. The misuse and overuse of antibiotics, however, has contributed to antibiotic resistance, making antibiotics less effective at saving lives. Levy and co-author Bonnie Marshall summarize and synthesize the findings of a large number of studies assessing the link between antibiotic resistance and the use of non-therapeutic antibiotics in livestock and fish farming. Highlights include the following.
