Who Will Feed China

Twenty years ago, Lester Brown published an article in World Watch magazine entitled "Who Will Feed China?" A year later, he followed with a book of the same name.

The article and book generated an enormous outcry from China and dozens of conferences, seminars, and studies, as he writes in his autobiography, Breaking New Ground.

"In 1994 I wrote an article for the September/October issue of World Watch magazine entitled "Who Will Feed China?" The late August press conference releasing it generated only moderate coverage. But when the article was reprinted that weekend on the front of the Washington Post’s Outlook section with the title "How China Could Starve the World," it unleashed a political firestorm in Beijing. …

The World Watch article attracted more attention than anything I have ever written. In addition to appearing in our magazine’s five language editions—English, Japanese, Chinese (Taiwan), German, and Italian—it also appeared in abridged form in many of the world’s leading newspapers, including the Washington Post, Los Angeles Times, and the International Herald Tribune. It was syndicated internationally by both the Los Angeles Times and The New York Times. Among the other major news organizations covering the analysis were the Associated Press and The Wall Street Journal, including the Asian edition. …

One of the most interesting responses was in Washington, DC, where the National Intelligence Council, the umbrella over all the U.S. intelligence agencies, analyzed the effect of China’s growing demand for grain on world agriculture and any security threats that it might pose. A panel of prominent researchers, led by Michael McElroy, then head of the Department of Earth and Planetary Sciences at Harvard, produced a first-rate study of several hundred pages. …

Meanwhile, within China, every few weeks another study was released attempting to demonstrate why my analysis was wrong. These critiques came from such disparate sources as a scientist from the Chinese Academy of Sciences, an official from the Ministry of Agriculture, and an independent academic scholar. Not long after, an enterprising Chinese publisher took a copy of the original World Watch magazine article and a collection of the critiques of it and published them in a book entitled The Great Debate Between Lester Brown and China. …

Over time, China’s leaders came to both appreciate and acknowledge how Who Will Feed China? had helped change their thinking. A late 1998 issue of Feedstuffs, a weekly agribusiness newspaper, quotes Lu Mai, an agricultural economist and senior fellow at a government think tank in Beijing, as saying, "Brown seems to have been accorded guru status in high places. ‘He’s like the monk from outside who knows how to read the Bible.’" …

Lester proved prescient in his analysis. China is a leading importer of grain and it imports a staggering 60 percent of all soybeans entering world trade—and it looks like it will continue. The problem is not so much population growth, but China’s rising affluence, which is allowing its population to move up the food chain, consuming more grain-intensive livestock, poultry, and farmed fish.

Janet Larsen, EPI’s director of research, wrote last year on the Chinese purchase of Smithfield, the world’s leading pork producer. She has also written on how China’s meat consumption has grown to double that of the United States where meat consumption is falling.

Essentially, twenty years later, we are still wondering who will feed China?

Lester has written a number of articles over the last dozen years about China, which are available on Earth Policy Institute’s website. Below are some highlights. More

Henan’s Big Drought. Is This From The South–North Water Transfer Project?

Mainland media reported that, since this summer, Henan Province rainfall is 60 percent less than usual over the same period since 1951, which is the lowest value over the same period of history. Pingdingshan City's main water source, Baiguishan reservoir water level is even lower than the dead water of 97.5 meters.

Henan Zhecheng County Shuangmiao Village Ms. Li, “over the entire summer it did not rain. The crops are dry. We are not allowed to irrigate the crops. If I use the well water, I probably cannot even have drinking water."

Droughts have had a serious impact on local agriculture.

Ms. Li, "most places basically have no harvest. Individual crops can be harvested a little, but there is not much. If one place can harvest 40 percent, that’s the best.''

Hubei Province is rich in water during the main flood season this year. But rainfall in most areas decreased by more than 20 percent. 111 small reservoirs and over 50,000 ponds dried up; over 600 reservoirs are below the dead water level; Hanjiang River downstream water level dropped. Danjiangkou reservoir water level is only 142.77 meters on August 19. This is far below the SNWTP planned water level of 170 meters.

For this major disaster, the authorities explained that the drought is caused by a variety of climatic reasons. They claimed that, even if the current trend of precipitation is "north flood south dry", it is still to "transfer water from south to north" to fill the gap of an especially severe water shortage in Beijing.

But the villagers in drought regions have different thoughts.

Ms. Li, " we all think it is due to the SNWTP. In previous years, it was not as dry as in these years."

Villagers discussed and believe that, SNWTP leads the Han River, the Yangtze River and the Yellow River water back and forth; the Three Gorges Reservoir also caused natural flowing rivers to change direction. Poor circulation, and loss of groundwater resources are also very serious. It has a massive impact not only to the surrounding geological environment, but also caused imbalances to the water, clouds, rain, and natural circulation system leading to a severe drought.

Living in Germany, water resources expert Wang Weiluo, has published many articles about Jiang Zemin who to "supply water to the 2008 Beijing Olympics", hastily approved and launched the SNWTP in 2001. It introduced one billion cubic meters of water annually to Beijing, with diversion channels crossing more than 700 natural rivers in Central China. The project completely

broke the law of nature of these rivers; There is a serious engineering problem, even bigger than the Three Gorges, and the threat is to a wider area.

Beijing electrical engineer Mr. Tian, "in principle there is a problem, because it is not that the south is high, the north is low, and it naturally flows across. It is to artificially add a number of processes, which undermines the law of nature. I think this may be even worse than the Three Gorges Dam."

Problems have been reported recently about SNWTP by the media. When the Diversion project tested the water on July 3 for the first time, the media exposed that the water source from Danjiangkou Reservoir exceeded the nitrogen content, and was seriously polluted. The official also acknowledged that water quality for nitrogen and phosphorus exceeded the standards. However he stressed that it would naturally degrade through long-distance transportation.

In late July, the mainland media also reported that SNWTP led to a decrease in the Han River water level. Due to the reduced water flow the fish were unable to spawn by end of July, while in previous years they had finished spawning. Yicheng city located by the Han River was without water three times since last year, the longest time was 48 hours.

In addition to the environmental damages, Beijing electrical engineer Mr. Tian pointed out that the drain from SNWTP is likely to outweigh the benefits.

Mr. Tian, "this unnatural process takes a lot of energy and wastes a lot of water. Introduce ten percent water, and finally arriving in Beijing, maybe even not two percent will get there."

SNWTP has three water diversion routes, namely the east, middle and west line. Of which the middle and east lines cost amounted to 500 billion yuan, 2.5 times larger than the Three Gorges Project. The East line is pumped from the Yangtze River to Tianjin, Qingdao and Yantai direction. The Midline is from Danjiangkou Reservoir as a division of Yangtze tributary the Han River, in Beijing’s direction; The West line is from the upper Yangtze River to the Yellow River water diversion. The East line started in December 2002, until December 8, 2013 the water went through. The Midline started in December 2003, is expected to have water through in October 2014. The West Line has not been started yet. More

California’s New Groundwater Legislation Is Unfair. The Governor Should Sign It Anyway.

In California, the score is now: Drought 1, Farmers 0. After years of shockingly dry conditions, fallow fields, freeloading salmon, and forced livestock sales, the state’s legislature has finally taken action.

On Friday, California lawmakers approved a historic measure that would regulate groundwater for the first time in state history. California was the only Western state without controls on the amount of water taken from wells. Gov. Jerry Brown is expected to sign the legislation later this month.

The legislation, which is really three separate bills, intends to limit overpumping by directing local agencies to construct their own "groundwater sustainability plans," with fines for violations. There are also provisions for the state to usurp local plans if they continue to result in groundwater depletions after 2025. A $7.5 billion water bond, another major effort at expanding the state’s already vast water storage and delivery infrastructure, was previously agreed upon and will be placed in front of voters on the November ballot.

The measures were passed hours before the legislative session came to a close, drawing the ire of state agricultural interests, which will likely be most affected by the new rules. The contentious final votes came not along Republican-Democratic lines but a rural-urban divide, with a bipartisan contingent from the agriculturally rich Central Valley staunchly opposed. In California, farmers use more than 80 percent of the state’s water. They’re also the most productive in the nation, leading the way in growing everythingfrom asparagus to walnuts. Farmers there deserve to get the majority of the state’s water, a resource they’ve molded into a multibillion dollar industry that feeds each of us every day. The problem is, there’s currently no real incentive to save dwindling aquifers there, as huge subsidies continue to tempt big agriculture into water-intensive crop choices. Last week’s actions by the state legislature are an attempt to change that.

Despite what essentially amounts to an unjust loss of water rights for Central Valley landowners, the bill should be celebrated. Without a legislative step of this magnitude, it’s only a matter of time before agriculture in its current form becomes impossible in California. Farmers must adapt to a future with less water, and there’s no time like the present.

Earlier this year, I wrote extensively about California water issues in a Slate series called the Thirsty West. On my drought-themed road trip, I met rancher and Tulare County Deputy Agricultural Commissioner Gavin Iacono and Central Valley almond farmer Benina Montes. This week, I spoke with both of them again by phone to gauge their initial reaction to the new regulations.

Iacono says the Central Valley has turned into an arms race of drilling for water. "It’s amazing in just my commute each day, how many well rigs I see out and around. It’s a one- to two-year wait to get a well crew in. I know people that are on a waiting list for four or five different well companies."

According to Montes, the new rules may help make things fairer. As it is currently, he says, "If you’ve got more money, you can go deeper. It’s like, ‘Great, you win.’ "

The drought has hit Iacono hard. This year, he sold his cattle herd because there was no hay left to feed them. Friends are starting to talk about leaving. "More and more, we’ve thought of it, too," he says.

He’s worried—with good reason—that the drought in California may just be getting started. New research led by Cornell University calculated up to a 50 percent chance of a 35-year megadrought later this century. Lead author Toby Ault told the university’s press office that "with ongoing climate change, [the current drought in the West] is a glimpse of things to come. It’s a preview of our future."

Said Iacono, "If that’s true, none of us will survive out here."

Still, Iacono says he has mixed feelings on the new rules. "If they limit how much [groundwater] you can use, that will dictate what crops you can grow. It’s going to lower your property value, and potentially your ability to use the land." He continued, "When you’re legislated out of something that’s been in your family for generations, it’s hard to stomach when you have other people telling you what you can and can’t do."

In the meantime, farmers like Montes are flying a bit blind. Montes pumps vast quantities of water each year for her family’s almond orchard, but has taken steps to try to be as efficient as possible, using drip irrigation and organic management methods. The new legislation should help encourage more farmers to adopt water-saving practices like these.

Montes repeated a groundwater analogy she overheard at a recent Farm Bureau meeting: "Right now we have a bank account, but you don’t really know how much is there. We can’t keep making withdrawals forever." She continued, "It’s hard, because nobody likes being told what to do, but we gotta protect it." More

Grain Harvest Fact Sheet

With grain providing much of the calories that sustain humanity, the status of the world grain harvest is a good indicator of the adequacy of the food supply.

Lester Brown

More than 2 billion tons of grain are produced each year worldwide, nearly half of it in just three countries: China, the United States, and India.

Corn, wheat, and rice account for most of the world’s grain harvest. Whereas rice and most wheat are consumed directly as food, corn is largely used for livestock and poultry feed, and for industrial purposes.

Global grain consumption has exceeded production in 8 of the last 14 years, leading to a drawdown in reserves.

Population growth is the oldest source of increasing grain demand. In recent years, the annual growth in grain use has doubled, largely a result of increased use for fuel ethanol and livestock and poultry feed.

In 2013, the United States harvested more than 400 million tons of grain. Of this, 129 million tons (30 percent) went to ethanol distilleries.

Rising yields are the key to expanding the grain harvest as there is little unused cropland. Since 1950, over 93 percent of world grain harvest growth has come from raising yields.

The global grain area planted per person has shrunk from about half an acre (0.2 hectares) in 1950 to a quarter acre (0.1 hectares) in 2013.

At 10 tons per hectare, U.S. corn yields are the highest of any major grain anywhere. In Iowa, some counties harvest up to 13 tons per hectare.

Global average grain yields more than tripled from 1.1 tons per hectare in 1950 to 3.5 tons per hectare in 2013. However, yield growth has slowed from 2.2 percent a year between 1950 and 1990 to 1.4 percent in the years since.

In France, Germany, and the United Kingdom, wheat yields have been flat for more than a decade. The story is similar for rice in Japan and South Korea.

World fertilizer use climbed from 14 million tons in 1950 to 181 million tons in 2013. But in many countries, fertilizer use has reached diminishing returns.

Since 2007, the world has experienced three major grain price spikes. The U.N. Food Price Index indicates that grain in 2014 was twice as expensive as in 2002–04.

Rising global temperatures threaten the world’s major food crops; the “rule of thumb” is that each 1-degree-Celsius rise in temperature (1.8 degrees Fahrenheit) above the growing season optimum can cut productivity by at least 10 percent. More

Which Ocean Species Will Outlast the Rising Acidity of Seawater?

Many of the projected effects of climate change on the world’s oceans are already visible, such as melting polar ice caps and rising sea levels. But invisible changes may be the most threatening to human food sources, beginning with the tiny species like plankton that inhabit the bottom of the oceans’ food chain.

As emissions from human activities increase atmospheric carbon dioxide, they, in turn, are modifying the chemical structure of global waters, making them more acidic.

Many researchers have speculated that most aquatic species won’t be able to adapt in time to survive the acidification that has already begun, but there are some who are more optimistic. One of them is Jennifer Sunday, a postdoctoral ecologist and evolutionary biologist at Canada’s Simon Fraser University.

“You hear people say species aren’t going to adapt in time,” she explained in an interview, “but I just knew that we don’t really know that. This really motivated me to start thinking about a study to test this. We can and did put some science and data to this question.”

Sunday and her team published a review earlier this year in Trends in Ecology and Evolution, aiming to help researchers improve their chances of finding potential survivors. It suggests that more studies should focus on identifying species with enough genetic variety to produce a mutant that can adapt.

Sunday feels that the better researchers get at searching for adapters, the more will be found.

The process that creates this risk is swift and globe-spanning. Oceans absorb roughly a quarter of the rising CO2 emissions from the atmosphere, so as that concentration increases, the oceans absorb more of the gas. In the past 150 years, human-induced climate change has changed the ocean acidity from roughly pH 8.3 to pH 8. (In the pH scale, 1 is most acidic, 7 is neutral and 14 is basic, or least acidic).

“It’s anywhere from 10 to 100 times faster than anything we’ve seen over the last million years,” said Richard Feely, a chemical oceanographer and senior researcher with the National Oceanic and Atmospheric Administration. “That’s just according to our good records.” And acidity is only expected to rise.

“By the end of this century,” Feely said, “projections are an increase by another 100 to 130 percent.”

Which tiny sea creatures can win the lottery?Changes in pH levels can have massive effects on marine life, a fact that has led many scientists to believe that most species can’t withstand large increases in acidification. When CO2 mixes with ocean waters, it binds calcium molecules that are usually free for marine creatures to build shells. The more acidic waters can also corrode existing shells.

Sunday isn’t the first to try and isolate survivor species. Several teams worldwide have already been exploring the potential of marine life species to adapt to predicted climate changes.

In 2009, a European team published their research on the tiny circular plankton Emiliania huxleyi, made up of light-reflecting mineralized calcium ovals. These tiny plankton sometimes float in populations so large, they’ve been spotted from outer space.

Looking at strains of the plankton under varying CO2 levels, researchers found that while some plankton had difficulties forming their shells when the water was more acidic, others did not, causing researchers to speculate that the plankton might be able to use another form of calcium to substitute in shell making. Other studies have shown that certain species thought incapable of evolving quickly can, in fact, rapidly adapt.

Evolution is like a lottery. The faster a species reproduces, the greater the number of unique ticket combinations it creates in the genes of its offspring. For species that produce the right genetic mutation, their number is drawn and the prize is survival.

“This is particularly important when you want to look at a species’ ability to cope with change,” said Jennifer Pistevos, a master of research student at the Marine Biological Association, who studied clone populations of Celleporella hyalina, a tiny organism she found to have an amazing ability to reproduce in both more acidic and warmer water conditions.

“Faster reproduction rates give us a chance to see how vulnerable a species is,” Pistevos said.

In 2012, Sunday and colleagues spanning three continents reviewed past studies, and based on this work, propose future research dedicated to efforts to locate adapters by incorporating more experimental evolution into the studies.

Experimental evolution identifies members of a species born with the winning genetic ticket instead of those who can come up with the correct number during their lifetime. Being born with the winning ticket means these individuals may be able to ride the acidifying tides in the kind of time frame needed—which is immediately.

Questions that can’t be answered in the labSunday and her team also suggest more work should consider a species’ response to multiple environmental changes, such as increased temperature and oxidation levels, as well as multiple stages of life. Currently, many studies only follow a species at a specific point in its members’ lives, such as infancy. Without tracking an organism over its life span and in a complicated and changing environment, it’s hard to say whether observed changes will translate into overall survival.

Although Sunday sees her work as laying the groundwork for less pessimistic predictions of the future fate of marine life, not everyone agrees that the approach is realistic. Aran Mooney, a biologist at the Woods Hole Oceanographic Institute who studies the effects of ocean acidification on Atlantic long-fin squid larvae, said some methods Sunday recommends are not practical for studying all species.

“Overall, the review is very good for us,” he said. “The authors point out some great goals and the limitations we face.” But for species like squid, Mooney said, Sunday’s suggestions are unlikely to be used.

“Measuring squid evolution in the lab might be doable to some extent,” Mooney said, “but it isn’t really possible to raise multiple generations or even young to adult—[they] don’t do all that well in captivity.”

Though Sunday agreed that predicting exactly how oceans will look in the future remains hard, researchers are starting to look in the right places. “The question just seemed too difficult before,” she said. “We wanted to put our advice out there so people could see it’s not impossible for species to adapt in time.”

“I do predict some species will adapt,” concluded Sunday, “but not all. Ultimately, it’s pretty shocking to think we’ll be losing species and it will be because of us.” More

China Experiment in Permaculture Offers World Hope

China is the most populous and possibly one of the most diverse nations on the planet, with a population of over 1.3 billion people and 56 ethnic groups.

What each one of those people shares with the rest of the world, regardless of political, linguistic, economic, and existential differences, is the complete and utter dependence on the ability to find food. In China’s Loess Plateau, sustained generational farming had depleted the soil, leaving in its wake a textured landscape of dust. When winds came, the dust blew into cities, compromising air quality. In the rains, it washed down the valley, depositing more of the silt that gives the Yellow River its name. In 1995, scientists and engineers surveyed the land of the Loess Plateau in an attempt to determine what was causing the once fertile belt to be a thorn in the country’s. The results of their study led to an experiment in permaculture in China that offers hope to the world.

John D. Liu, Chinese American ecologist and documentary film-maker, documented the project in an award-winning film called Hope in a Changing Climate. In the film that Liu narrates, he reports that the first thing that the scientists discovered was a causal relationship between ecosystem destruction and human poverty. Where environmental degradation is severe, the population becomes trapped in a downward spiral. Because they needed to eat to survive, generational subsistence farming had stripped the land bare in the Loess Plateau. In search of food for themselves and their flocks, farmers and their families continued to deplete the fertility of the surrounding ecosystem, further impoverishing themselves.

When scientists developed the plan to restore the ecosystem in China’s Loess Plateau, generational farmers had to be convinced that not farming was critical for their families’ long-term survival. To get buy in from the locals who did not understand how their families would eat if they were not allowed to farm, the government subsidized them and taught them how to do the work that would restore their land from a scarce dirt pit to a thriving ecosystem.

Around the world, populations are living a scarce subsistence lifestyle similar to the one that the citizens of China’s Loess Plateau used to live. The United Nations High Commissioner for Refugees (UNHCR) states that besides fleeing for personal safety, the basic need for food and shelter is the primary motivation for people leaving their homes and becoming displaced. If there were a stable food supply and supportive ecosystem, then the motivation for the world’s most vulnerable populations to move, would decrease. The UNHCR reports that competition for scarce resources triggers violence. If there were a way to restore resources so that people had food and a sense of power in their lives, the fuel for much of the world’s violence would be spent.

The permaculture experiment in China indeed offers hope to the world. Working with scientists, the local population terraced slopes, they planted trees, and they penned their herds so that the trees could grow without being eaten. Soon they found that their hillsides were green. Instead of letting the rains sheet off the mountains, the terraces collected the water and fed the delicate new roots systems, transforming the arid land into a booming garden. Liu reports that since he first visited the area in 1995, the people have seen a threefold increase in income and a profound sense of hope and empowerment. More

Rains Failing Over India:

Feeble 2014 Monsoon Heightens Concerns That Climate Change is Turning A Once-Green Land into Desert

El Nino has yet to be declared. Though signs of the Pacific Ocean warming event abound, they are still in the early stages. But for all the impact on the current Indian Monsoon — the rains this vast sub-continent depends on each year for a majority of its crops — the current pre-El Nino may as well be a monster event comparable to 1998.

For the rains that have come so far have been feeble. By June 18, precipitation totals were more than 50% below the typical amount by this time of year for northern and central India and 45% below average for the country as a whole. A stunted Monsoon that many are saying is about as weak as the devastatingly feeble 2009 summer rains. And with Pacific Ocean conditions continuing to trend toward El Nino, there is concern that this year’s already diminished rains will snuff out entirely by mid-to-late summer, leaving an already drought-wracked India with even less water than before.

Through June 25th, the trend of abnormally frail monsoonal rains continued unabated:

India cloud cover on June 25, 2013 [Left Lower image] compared to India cloud cover on June 25 of 2014 [right upper image].

Note the almost complete lack of storms over India for this year compared to 2013 when almost the entire country was blanketed by rains. Image source: LANCE-MODIS.)

India’s Rain Pattern Has Changed

It’s not just that 2014 is a bad year for India. It’s that the current weakened monsoon comes at the tail end of a long period in which the rains have increasingly failed. Where in the past it took a strong El Nino to stall the rains, ever-increasing human atmospheric and ocean warming have pushed the threshold for Monsoonal failure ever lower. Now even the hint of El Nino is enough to set off a dry spell. A growing trend of moisture loss that is bound to have more and more severe consequences.

A new study by Stanford University bears out these observations in stark detail. For the yearly monsoon that delivers fully 80 percent of India’s rains has fallen in intensity by more than 10% since 1951. And though a 10% loss may seem relatively minor, year on year, the effects are cumulative. Overall, the prevalence of dry years increased from 1981 to 2011 by 27% and the number of years experiencing 3 or more dry spells doubled.

Meanwhile, though a general drying trend has taken hold, rain that does occur happens in more intense bursts, with more rain falling over shorter periods. These newly intensified storms are more damaging to lands and homes, resulting in both increasing destruction of property while also greatly degrading the land through more intense erosion.

25 Percent of India’s Land is Turning to Desert

Loss of annual monsoonal rains is coming along with a dwindling of water flows from the melting Himalayan glaciers. These two climate change induced drying effects are already having stark impacts.

For according to the Indian Government’s Fifth National Report on Desertification, Land Degradation and Drought, a quarter of India’s land mass is now experiencing desertification even as 32 percent is suffering significant degradation due to heightening dryness and erosion. This amounts to more than 80 million hectares of land facing desertification while more than 100 million hectares are steadily degrading. The report also noted that areas vulnerable to drought had expanded to cover 68% of the Indian subcontinent.

From the report: (India Monsoon.)

Desertification and loss of biological potential will restrict the transformation of dry lands into productive ecosystems. Climate change will further challenge the livelihood of those living in these sensitive ecosystems and may result in higher levels of resource scarcity.

Monsoonal Delay, Weakening Continues

By today, June 26, the long disrupted and weakened monsoon continues to sputter. Moisture flow remains delayed by 1-2 weeks even as the overall volume of rainfall is greatly reduced.

Though storms have exploded over some provinces, resulting in flash flooding, much of the country remained abnormally dry.

Overall, preliminary negative rainfall departures remained at greater than 40% below average for most of the nation with only five provinces receiving normal rainfall and the remaining 31 receiving either deficient or scant totals. More

 

 

 

Widespread impacts of neonicotinoids 'impossible to deny'

Neonicotinoid pesticides are causing significant damage to a wide range of beneficial species and are a key factor in the decline of bees, say scientists.

Researchers, who have carried out a four-year review of the literature, say the evidence of damage is now "conclusive".

The scientists say the threat to nature is the same as that once posed by the notorious chemical DDT.

Manufacturers say the pesticides are not harming bees or other species.

Neonicotinoids were introduced in the early 1990s as a replacement for older, more damaging chemicals.

They are a systemic insecticide, meaning that they are absorbed into every cell in a plant, making all parts poisonous to pests.

But some scientists have been concerned about their impact, almost since the moment they were introduced.

Much of the worry has surrounded their effects on bees.

There's been a well documented, global decline in these critical pollinators.

Many researchers believe that exposure to neonicotinoids has been an important destabilising factor for the species.

'Worldwide impacts'

In 2011, environmental campaigners, the IUCN, established an international scientific taskforce on systemic pesticides to look into the impacts of these chemicals.

The members have reviewed over 800 peer reviewed papers that have been published in the past 20 years.

Their assessment of the global impact says the threat posed goes far beyond bees.

In their report, to be published next month, they argue that neonicotinoids and another chemical called fipronil are poisoning the earth, the air and the water.

The pesticides accumulate in the soil and leach into water, and pose a significant problem for earthworms, freshwater snails, butterflies and birds.

The researchers say that the classic measurements used to assess the toxicity of a pesticide are not effective for these systemic varieties and conceal their true impact.

They point to one of the studies in the review carried out in the Netherlands.

It found that higher levels of neonicotinoids in water reduced the levels of aquatic invertebrates, which are the main prey for a whole range of species including wading birds, trout and salmon.

"There is so much evidence, going far beyond bees," Prof Dave Goulson from the University of Sussex told BBC News.

"They accumulate in soils, they are commonly turning up in waterways at levels that exceed the lethal dose for things that live in streams.

"It is impossible to deny that these things are having major environmental impacts."

DDT comparison

The scientists are very worried about the prophylactic use of neonicotinoids, where seeds are coated in the chemicals and the plant grows up with the ability to destroy pests already built in.

"It is a bit like taking antibiotics to avoid getting ill," said Prof Goulson, one of a team of 29 scientists involved in the research.

"The more they are used, the stronger the selective pressure you place on pest insects to become resistant to them. Using them as prophylactics is absolute madness in that sense."

The task force argues that with neonicotinoids and fipronil making up around a third of the world market in insecticides, farmers are over-relying on them in the same way as they once became over reliant on chemicals like DDT.

"We have forgotten those lessons and we're back to where we were in the 1960s," said Prof Goulson.

"We are relying almost exclusively on these insecticides, calendar spraying 20 times or more onto a single field, it's a completely bonkers way."

While neonicotinoids don't accumulate in human or animal tissue in the way that DDT once did, the modern pesticides are more lethal, about 6,000 times as toxic compared to the older spray.

Representatives of manufacturers say that there is nothing new in the task force study.

"There is very little credible evidence that these things are causing untoward damage because we would have seen them over 20 years of use," said Dr Julian Little from Bayer, one of the manufacturers of neonicotinoids.

"If you look at the tree bumblebee, it is eating the same food as the other bees, and is being exposed to the same pesticide load and weather conditions and yet it is flourishing, whereas some other bees are not.

"If it were pesticides causing the mass destruction of our fauna, surely you would see effects on all bees?"

The European Crop Protection Association said the task force was being selective in their evidence, pointing to recent studies carried out by industry showing that the declines in bee populations have been overstated.

"We respect the scientists who have produced this research, but it appears that they are part of a movement that brings together some academics and NGOs whose only objective is to restrict or ban the use of neonicotinoid technology regardless of what the evidence may show," a spokesperson said.

Europe already has a two-year moratorium in place meaning that neonicotinoids can't be used on flowering crops such as oilseed rape.

Last week, President Obama announced the creation of a pollinator health task force to look at the impact of pesticide exposure on bees and other insects.

Prof Goulson says that he isn't in favour of a ban.

"We have been using these things for 20 years and there's not a single study that shows they increase yield," he said.

"I'm not personally in favour of an outright ban but I think we should use them much more judiciously - if they don't benefit yield we should stop using them." More

Can GM and organic farms coexist?

Writing for the Guardian, Australian Research Council future fellow Matthew Rimmer said the ruling raised the prospect of "biotrespass" laws to protect organic farmers.

The decision in Marsh v Baxterwill no doubt reignite the debate over GM crop liability. A number of scholars have argued that there is a need to revise liability regimes in respect of biotechnology. Professor Jeremy de Beerfrom the University of Ottawa has argued that there is a need to adapt the legal principles of trespass to accommodate recent developments in biotechnology, nanotechnology, and synthetic biology. He has called for the creation of a cause of action for "biotrespass".

No doubt the agricultural biotechnology industry would resist such efforts at law reform. From their perspective, GM crops should be subject to the same liability regimes as other forms of farming and agriculture.

At an international level, there will be further debate over the position of GM crops in the sweeping regional agreements under negotiation – including the Trans-Pacific Partnership. There is an intense struggle between organic farmers and the biotechnology industry at a number of levels in these international agreements.

The Marsh's lawyer, Mark Walter, said the case would have ramifications for Australia's organic industry and raised the possibility of appeal:

"This is a disappointing result for Mr Marsh and leaves Australia’s non-genetically modified food farmers with no legal protection against contamination from nearby properties ... We will closely examine the judgement of this complex and unique case and advise our client of his legal options, including his right to appeal."

The Safe Food Foundation, which helped bankroll Marsh's case, said the future for organic food in Australia was now "uncertain". The Foundation said the judge had erred by criticising Australia's organic food regulators for stripping Marsh's organic status.

The court in its judgment stated the decision by NASAA (National Association of Sustainable Agriculture Australia) to decertify Steve was erroneous. Given the extent of the contamination of Steve’s farm we fail to see how NASAA could have taken any other decision. Certainly 100% of organic consumers would support the NASAA decision.

Because the court did not recognise the NASAA decertification the court did not recognise the economic loss Steve suffered, and dismissed the case that Steve had brought for negligence and nuisance.

Foundation director, Scott Kinnear, said:

“This is a huge setback for organic and Non GM farmers and their choice to remain GM Free. This has been an important test case, of interest to many parties, locally and globally.

“We also call on our legislators to work on finding a solution to this vexed issue. State and Federal governments have continuously stated that the solution to any GM contamination events is common law. This has clearly failed today and demonstrates that the law has not kept up with new technologies such as GM.”

NASAA general manager Ben Copeman said the decision highlighted the need for legislative change for the sector and that it had opened up a "Pandora box" of conflict between the GM and organic farming sectors.

“We found GM canola growing on organically certified land. The court found that there was no risk of GM contamination. While tolerance thresholds for GM contamination are governed by the Federal Government under the National Standard for Organic and Biodynamic Produce, it is not a legislated standard and is not recognised by the courts."

Corporate stranglehold of farmland a risk to world food security, study says

The world's food supplies are at risk because farmland is becoming rapidly concentrated in the hands of wealthy elites and corporations, a study has found.

Small farmers, the UN says, grow 70% of the world's food but a new analysis of government data suggests the land which they control is shrinking every year as mega-farms and plantations squeeze them onto less than 25% of the world's available farmland, says international land-use group Grain. These mega-farms are less productive in terms of amount of food they produce per area of land, the report argues.

"Small farms have less than a quarter of the world's agricultural land – or less than 20% excluding China and India. Such farms are getting smaller all the time, and if this trend persists they might not be able to continue to feed the world," says the report which draws on government statistics and calls for a stop on land grabbing by corporations.

The report suggests that the single most important factor in the drive to push small farmers onto ever smaller parcels of land is the worldwide expansion of industrial commodity crop farms. "The powerful demands of food and energy industries are shifting farmland and water away from direct local food production to the production of commodities for industrial processing," it says. The land area occupied by just four crops – soybean, oil palm, rapeseed and sugar cane – has quadrupled over the past 50 years. Over 140 million hectares of fields and forests have been taken over by these plantations since the 1960s – roughly the same area as all the farmland in the EU.

"What we found was shocking," said Henk Hobbelink of Grain. "If small farmers continue to lose the very basis of their existence, the world will lose its capacity to feed itself. We need to urgently put land back in the hands of small farmers and make the struggle for agrarian reform central to the fight for better food systems."

Big farms have been getting bigger nearly everywhere with rising numbers of small and medium-sized farmers going out of business in the past 20 years, say the authors. Belgium, Finland, France, Germany and Norway in western Europe have each lost about 70% of their farms since the 1970s while Bulgaria, Estonia, the Czech Republic and Slovakia each lost over 40% of their farms from 2003 to 2010. Poland alone lost almost 1m farmers between 2005 and 2010.

"Within the EU as a whole, over 6m farms disappeared between 2003 and 2010, bringing the total number of farms down to almost the same level as in 2000, before the inclusion of 12 new member states with their 8.7m new farmers," says the report , released with international peasant organisation Via Campesina.

But the concentration of land ownership is seen on every continent. Argentina lost more than one-third of its farms in the two decades from 1988 to 2008. Between 1997 to 2007, Chile lost 15% of its farms with the biggest farms doubling their average size, from 7,000 to 14,000 ha per farm. The United States has lost 30% of its farms in the last 50 years. Here, the number of very small farms has almost tripled, while the number of very large farms has more than quintupled.

In addition most farms have been getting smaller over time due to factors such as population pressure and lack of access to land. In India, the average farm size roughly halved from 1971 to 2006. In China, the average area of land cultivated per household fell by 25% between 1985 and 2000. In Africa, average farm size is also falling.

The authors say land reform is urgently needed if enough food is to be grown to feed everyone. "What we see happening in many countries ... is a kind of reverse agrarian reform, whether it's through corporate land grabbing in Africa, the recent agribusiness-driven coup d'état in Paraguay, the massive expansion of soybean plantations in Latin America, the opening up of Burma to foreign investors, or the extension of the European Union and its agricultural model eastward," says Hobbelink.

"In all of these processes, control over land is being usurped from small producers and their families, with elites and corporate powers pushing people onto smaller and smaller land holdings, or off the land entirely into camps or cities," he said.

The takeover of small farmers' land is now accelerating, says the report with nearly 60% of this land use change occurring in the past 20 years. The report estimates that 90% of all farms worldwide are "small", holding on average 2.2 hectares.

The report also found that small farmers often twice as productive as large farms and are more environmentally sustainable. "Although big farms generally consume more resources, control the best lands, receive most of the irrigation water and infrastructure ... they have lower technical efficiency and therefore lower overall productivity. Much of this has to do with low levels of employment used on big farms in order to maximise return on investment.

"Our data [suggests] that if all farms in Kenya had the current productivity of the country's small farms, Kenya's agricultural production would double. In Central America and Ukraine, it would almost triple. In Hungary and Tajikistan it would increase by 30%. In Russia, it would be increased by a factor of six," the report says.

"Beyond strict productivity measurements, small farms also are much better at producing and utilising biodiversity, maintaining landscapes, contributing to local economies, providing work opportunities and promoting social cohesion, not to mention their real and potential contribution to reversing the climate crisis."

The most productive farmers in the world are possibly found in Botswana, the report argues, where 93% of the farmers have small patches of land but together they grow all the country's groundnuts, 99% of its maize, 90% of the millet, 73% of beans and 25% of the sorghum on just 8% of the farmland.
