Ground water depletion driving global conflicts - NASA scientist

ROME, Nov 7 (Thomson Reuters Foundation) - Global ground water supplies, crucial for sustaining agriculture, are being depleted at an alarming rate with dangerous security implications, a leading scientist said.

"It's a major cause for concern because most of the places where it (ground water depletion) is happening are major food producing regions," James Famiglietti, a University of California professor who conducts research for the National Aeronautics and Space Administration (NASA), said in an interview with the Thomson Reuters Foundation.

"India is the worst off, followed by the Middle East, and the U.S. is probably number three ... the Chinese, particularly on the north China plain, are more water limited than people believe."

Famiglietti's conclusions are based on his latest research paper "The global ground water crisis" published in the journal Nature Climate Change last month.

The study uses analysis of satellite images to warn that ground water in many of the world's largest aquifers is being exploited at a far faster rate than it can be naturally replenished.

Farming accounts for more than 80 percent of the United States' water use, according to the U.S. Department of Agriculture, and the figures are similar globally.

Famiglietti has been called to the Pentagon a number of times to discuss the potential impact of groundwater scarcity with leading military planners.

Water-related conflicts are already happening, he said, and security experts are bracing for more.

"In 90 percent of the world where there are violent conflicts, there are water scarcity issues," he said.

Water scarcity has been one component driving Syria's civil war, he said. The agricultural sector lacks sufficient water to farm, and a "young generation of unhappy farmers moved to the city and conflict ensued".

Oil-rich, water scarce countries in the Gulf currently rely on desalinated sea water for much of their water consumption.

Some analysts suggest that more countries will embrace energy-intensive desalination, particularly using nuclear technology, if current trends continue.

Famiglietti said this would not be a good option, as it requires too much energy, and won't be able to efficiently provide the volumes of water needed for large-scale agriculture.

Governments first need to acknowledge there is a problem, he said, and then factor scarcity into pricing, while investing in conservation and new technologies to promote efficiency. 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

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:

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

Allan Savory: How to fight desertification and reverse climate change

"Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. And it's happening to about two-thirds of the world's grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos.Savory has devoted his life to stopping it. He now believes — and his work so far shows — that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.

Allan Savory works to promote holistic management in the grasslands of the world.

Full Planet, Empty Plates: The New Geopolitics of Food Scarcity

World agriculture is now facing challenges unlike any before. Producing enough grain to make it to the next harvest has challenged farmers ever since agriculture began, but now the challenge is deepening as new trends—falling water tables, plateauing grain yields, and rising temperatures—join soil erosion to make it difficult to expand production fast enough.

As a result, world grain carryover stocks have dropped from an average of 107 days of consumption a decade or so ago to 74 days in recent years.

World food prices have more than doubled over the last decade. Those who live in the United States, where 9 percent of income goes for food, are largely insulated from these price shifts. But how do those who live on the lower rungs of the global economic ladder cope? They were already spending 50–70 percent of their income on food. Many were down to one meal a day before the price rises. Now millions of families routinely schedule one or more days each week when they will not eat at all.

What happens with the next price surge? Belt tightening has worked for some of the poorest people so far, but this cannot go much further. Spreading food unrest will likely lead to political instability. We could see a breakdown of political systems. Some governments may fall.

As food supplies have tightened, a new geopolitics of food has emerged—a world in which the global competition for land and water is intensifying and each country is fending for itself. We cannot claim that we are unaware of the trends that are undermining our food supply and thus our civilization. We know what we need to do.

There was a time when if we got into trouble on the food front, ministries of agriculture would offer farmers more financial incentives, like higher price supports, and things would soon return to normal. But responding to the tightening of food supplies today is a far more complex undertaking. It involves the ministries of energy, water resources, transportation, and health and family planning, among others. Because of the looming specter of climate change that is threatening to disrupt agriculture, we may find that energy policies will have an even greater effect on future food security than agricultural policies do. In short, avoiding a breakdown in the food system requires the mobilization of our entire society.

On the demand side of the food equation, there are four pressing needs—to stabilize world population, eradicate poverty, reduce excessive meat consumption, and reverse biofuels policies that encourage the use of food, land, or water that could otherwise be used to feed people. We need to press forward on all four fronts at the same time.

The first two goals are closely related. Indeed, stabilizing population depends on eliminating poverty. Even a cursory look at population growth rates shows that the countries where population size has stabilized are virtually all high-income countries. On the other side of the coin, nearly all countries with high population growth rates are on the low end of the global economic ladder.

The world needs to focus on filling the gap in reproductive health care and family planning while working to eradicate poverty. Progress on one will reinforce progress on the other. Two cornerstones of eradicating poverty are making sure that all children—both boys and girls—get at least an elementary school education and rudimentary health care. And the poorest countries need a school lunch program, one that will encourage families to send children to school and that will enable them to learn once they get there.

Shifting to smaller families has many benefits. For one, there will be fewer people at the dinner table. It comes as no surprise that a disproportionate share of malnutrition is found in larger families.

At the other end of the food spectrum, a large segment of the world’s people are consuming animal products at a level that is unhealthy and contributing to obesity and cardiovascular disease. The good news is that when the affluent consume less meat, milk, and eggs, it improves their health. When meat consumption falls in the United States, as it recently has, this frees up grain for direct consumption. Moving down the food chain also lessens pressure on the earth’s land and water resources. In short, it is a win-win-win situation.

Another initiative, one that can quickly lower food prices, is the cancellation of biofuel mandates. There is no social justification for the massive conversion of food into fuel for cars. With plug-in hybrids and all-electric cars coming to market that can run on local wind-generated electricity at a gasoline-equivalent cost of 80¢ per gallon, why keep burning costly fuel at four times the price?

On the supply side of the food equation, we face several challenges, including stabilizing climate, raising water productivity, and conserving soil. Stabilizing climate is not easy, but it can be done if we act quickly. It will take a huge cut in carbon emissions, some 80 percent within a decade, to give us a chance of avoiding the worst consequences of climate change. This means a wholesale restructuring of the world energy economy.

The easiest way to do this is to restructure the tax system. The market has many strengths, but it also has some dangerous weaknesses. It readily captures the direct costs of mining coal and delivering it to power plants. But the market does not incorporate the indirect costs of fossil fuels in prices, such as the costs to society of global warming. Sir Nicholas Stern, former chief economist at the World Bank, noted when releasing his landmark study on the costs of climate change that climate change was the product of a massive market failure.

The goal of restructuring taxes is to lower income taxes and raise carbon taxes so that the cost of climate change and other indirect costs of fossil fuel use are incorporated in market prices. If we can get the market to tell the truth, the transition from coal and oil to wind, solar, and geothermal energy will move very fast. If we remove the massive subsidies to the fossil fuel industry, we will move even faster. 10

Although to some people this energy transition may seem farfetched, it is moving ahead, and at an exciting pace in some countries. For example, four states in northern Germany now get at least 46 percent of their electricity from wind. For Denmark, the figure is 26 percent. In the United States, both Iowa and South Dakota now get one fifth of their electricity from wind farms. Solar power in Europe can now satisfy the electricity needs of some 15 million households. Kenya now gets one fifth of its electricity from geothermal energy. And Indonesia is shooting for 9,500 megawatts of geothermal generating capacity by 2025, which would meet 56 percent of current electricity needs. More

Anxieties mount in drought-stricken California

Ryan Jacobsen and his family have been farming their land for four generations. His ancestors were Volga Germans from the territories surrounding Russia's Volga River. More than 100 years ago, they settled in central California, in the town of Fresno, about a two-hour's drive southeast of San Francisco. They cultivated wine and grew fruits and vegetables. Jacobsen likes to talk about the past with his grandfather, who is now over 90 years old, but now, the dry spell is the only issue.

"The drought here in San Joachin Valley is absolutely the worst we've ever seen. And what we're looking at as far as this year, we're looking at hundreds of thousands of acres being fallowed, tens of thousands of jobs being lost, and billions of dollars of economic activity not coming to this community," said the 34-year-old farmer.

It has hardly rained in the last three years. The tall, lanky Ryan stands in front of one of his fields and shows how economically he and the farmers in the neighborhood use the precious water. Long hoses, which lay a few inches beneath the surface, lead the water straight to the roots of the turnips. The water is transported many miles through canals to the fields and originates from nearby reservoirs.

"Nothing evaporates here," Jacobsen said.

Big water bills

One local water supply is the San Luis Reservoir. During the winter, it's generally filled up to the rim due to rainy weather in the cold season. In the spring, melt water from the mountains also fills the reservoir. But because of the lack of rain, the reservoir is only 40 percent filled. What's usually a green shore now resembles a brown lunar landscape. And it becomes wider and wider the more the water level drops.

The water from this reservoir is expensive. Farmers pay around $100 (73 euros) to irrigate a small field for a few hours, which means the cost of cultivating crops increases. But higher costs for the products can't always be passed on to consumers. The competition in the agriculture business is stiff. Strawberries, grapes and nuts from Latin American countries are increasingly entering the US market.

"Eventually, you reach a point where farming isn't worth it," said Fotis Bilios. He works on a big farm that employs 300 workers and is located half an hour's drive from Fresno. Thousands of seasonal workers also help at the site to generate an annual turnover of $80 million. But the profits are plummeting now that rain is scarce.

"A quarter of the 7,100 hectares of farmland lies fallow," said the 43-year-old during a tour through the area. The "Stamoulis" farm is one of the most modern farms in California, and Bilios expects it will survive the drought. "It's a lot more difficult for many small farms," he added.

Facing financial ruin

Hundreds of farmers face bankruptcy, says Juliet Christian-Smith from the Union of Concerned Scientists environmental organization in San Francisco. It might rain occasionally in the coming months, but it won't be enough to fill the reservoirs. That's a bleak prospect for agriculture - the most important economic sector in California, with 50 billion dollars in revenues per year.

When asked why there's no more rain, Christian-Smith says she believes it is caused by climate change.

"There's very high consensus around increasing droughts in the future related to global climate change, because not only are we having earlier snow melts and less snow pack, which is one of our largest water reservoirs in the western US, but we're also having hotter temperatures, which means that outdoor plants require more water to survive," she said.

California's Governor Jerry Brown has made efforts at raising awareness of climate change issues and recently declared a state of drought emergency. Authorities estimate that around 200,000 hectares of land can't be used due to current conditions. The resulting damages amount to five billion dollars, the government estimates.

Another reason for the drought is that California's population has doubled to 38 million people over the last four decades. More people mean more water is consumed.

Fotis Bilios - like most of the farmers - does not speak highly of the government. He believes that too much water is being pumped into the cities of San Francisco and Los Angeles. "What's more important - that the people are able to take long showers or that they have food?"

The fight for water has only just begun. More

Farmers worldwide suffer as extreme weather wreaks food havoc

To address the crisis, farm ministers from around the world are gathering in Berlin Saturday to discuss climate change and food production.

BOSTON — Volatile weather around the world is taking farmers on a wild ride. Too much rain in northern China damaged crops in May, three years after too little rain turned the world’s second-biggest corn producer into a net importer of the grain. Dry weather in the U.S. will cut beef output from the world’s biggest producer to the lowest level since 1994, following 2013’s bumper corn crop, which pushed America’s inventory up 30 percent. British farmers couldn’t plant in muddy fields after the second-wettest year on record in 2012 dented the nation’s wheat production.

“Extreme weather events are a massive risk to agriculture,” said Peter Kendall, president of the British National Farmers Union, who raises 3,953 acres of grain crops in Bedfordshire, England. “Farmers can adapt to gradual temperature increases, but extreme weather events have the potential to completely undermine production. It could be drought, it could be too much rain, it could be extreme heat at the wrong time. It’s the extreme that does the damage.”

Farm ministers from around the world are gathering in Berlin Saturday to discuss climate change and food production at an annual agricultural forum, with a joint statement planned after the meeting.

Fast-changing weather patterns, such as the invasion of Arctic air that pushed the mercury in New York from an unseasonably warm 55 degrees Fahrenheit on Jan. 6 to a record low of 4 the next day, will only become more commonplace, according to the New York-based Insurance Information Institute. While the world produces enough to provide its 7 billion people with roughly 2,700 calories daily, and hunger across the globe is declining, one in eight people still don’t get enough to eat, some of which can be blamed on drought, the United Nations said.

“There’s no question, while there’s variability and volatility from year to year, the number and the cost of catastrophic weather events is on the rise, not just in the U.S., but on a global scale,” said Robert Hartwig, an economist and president of the insurance institute. “It’s all but certain that the size and the magnitude and the frequency of disaster losses in the future is going to be larger than what we see today.”

The number of weather events and earthquakes resulting in insured losses climbed last year to 880, 40 percent higher than the average of the last 30 years, according to Munich Re, the world’s largest reinsurer.

Research points to a culprit: an increase in greenhouse gases, generated by human activity, that are forcing global temperatures upward, said Thomas Peterson, principal scientist at the U.S. National Climatic Data Center in Asheville, N.C. The warmer the air the more water it can hold, he said.

“What we’re finding worldwide is that heavy precipitation is increasing,” Peterson said.

Flood waters in Passau, Germany, in May and June reached the highest level since 1501, Munich Re said. That was the year Michelangelo first put a chisel to the block of marble that would become his sculpture of David. High water did $15.2 billion in damage in parts of Central and Eastern Europe, according to Munich Re.

A July hailstorm in Reutlingen, Germany, led to $3.7 billion in insured losses, according to Munich Re. Hailstones the size of babies’ fists cracked the windshield of Marco Kaschuba’s Peugeot.

“Two minutes before the storm started you could already hear a very loud noise,” said Kaschuba, a 33-year-old photographer. “That was from hailstones hitting the ground in the distance and coming closer.”

In 2012, Britain had its second-highest rainfall going back to 1910, according to Britain’s meteorology office. England and Wales had its third-wettest year since 1766. More

Full Planet, Empty Plates: The New Geopolitics of Food Scarcity - Lester Brown

Peak Water and Food Scarcity

Although many analysts are concerned about the depletion of oil resources, the depletion of underground water resources poses a far greater threat to our future. While there are substitutes for oil, there are none for water. Indeed, modern humans lived a long time without oil, but we would live for only a matter of days without water.

Not only are there no substitutes for water, but the world needs vast amounts of it to produce food. As adults, each of us drinks nearly 4 liters of water a day in one form or another. But it takes 2,000 liters of water—500 times as much—to produce the food we consume each day. 1

Since food is such an extraordinarily water-intensive product, it comes as no surprise that 70 percent of world water use is for irrigation. Although it is now widely accepted that the world is facing severe water shortages, not everyone realizes that a future of water shortages will also be a future of food shortages. 2

The use of irrigation to expand food production goes back some 6,000 years. Indeed, the development of irrigation using water from the Tigris and Euphrates Rivers set the stage for the emergence of the Sumerian civilization, and it was the Nile that gave birth to ancient Egypt. 3

Throughout most of history, irrigation spread rather slowly. But in the latter half of the twentieth century it underwent a rapid expansion. In 1950, there were some 250 million acres of irrigated land in the world. By 2000, the figure had nearly tripled to roughly 700 million acres. After these several decades of rapid increase, however, the growth in irrigated area has slowed dramatically since the turn of the century, expanding only 9 percent from 2000 to 2009. Given that governments are much more likely to report increases than decreases, the recent net growth in irrigated area may be even smaller. This dramatic loss of momentum in irrigation expansion, coupled with the aquifer depletion that is already reducing irrigated area in some countries, suggests that peak water may now be on our doorstep. 4

The trend in irrigated land area per person is even less promising. For the last half-century, the irrigated area has been expanding—but not as fast as population. As a result, the irrigated area per person today is 10 percent less than it was in 1960. With so many aquifers being depleted and more and more irrigation wells going dry, this shrinkage in irrigated area per person is likely not only to continue but to accelerate in the years ahead. 5

Roughly 40 percent of the world grain harvest is grown on irrigated land. The rest is rainfed. Among the big three grain producers—China, India, and the United States—the role of irrigation varies widely. In China, four fifths of the grain harvest comes from irrigated land. For India it is three fifths, and for the United States, only one fifth. Asia, where rice is the staple food, totally dominates the world irrigated area. 6

Farmers use both surface and underground water for irrigation. Surface water is typically stored behind dams on rivers and then channeled onto the land through a network of irrigation canals. Historically, and notably from 1950 until 1975, when most of the world’s large dams were built, this was the main source of growth in world irrigated area. During the 1970s, however, as the sites for new dams diminished, attention shifted from building dams to drilling wells for access to underground water. 7

Most underground water comes from aquifers that are regularly replenished with rainfall; these can be pumped indefinitely as long as water extraction does not exceed recharge. A small minority of aquifers are fossil aquifers, however, containing water put there eons ago. Since these do not recharge, irrigation ends once they are pumped dry. Among the more prominent fossil aquifers are the Ogallala underlying the U.S. Great Plains, the deep aquifer under the North China Plain, and the Saudi aquifers. 8

Given a choice, farmers generally prefer having their own wells because it enables them to control the timing and amount of water delivered with a precision that is not possible with large, centrally managed canal irrigation systems. Pumps let them apply water precisely when the crop needs it, thus achieving higher yields than with large-scale, river-based irrigation systems. Forty percent of world irrigated area is now dependent on underground water. As world demand for grain has climbed, farmers have drilled more and more irrigation wells with little concern for how many the local aquifers could support. As a result, water tables are falling and millions of irrigation wells are either going dry or are on the verge of doing so. 9

As groundwater use for irrigation expands, so does the grain harvest. But if the pumping surpasses the sustainable yield of the aquifer, aquifers are depleted. When this happens, the rate of irrigation pumping is necessarily reduced to the aquifer’s natural rate of recharge. At this point, grain production declines too.

The resulting water-based “food bubbles,” which create a short-term false sense of security, can now be found in some 18 countries that contain more than half the world’s people. In these countries, food is being produced by drawing down water reserves. This group includes China, India, and the United States. 10 (See Table 6–1.) More

ADB Releases Report on Managing the Water-Food-Energy Nexus


September 2013: The Asian Development Bank (ADB) has released a report, titled 'Thinking About Water Differently: Managing the Water-Food-Energy Nexus,' which argues for recognition of water as an economic and social good and the urgent assurance of regional water security to eliminate risk to food and energy security in Asia and the Pacific.


According to the ADB report, which offers high-level guidance on water issues affecting the region, governments need to think differently about water, taking a longer-term view of the limited resource. It highlights the importance of the following strategic approaches: reforming water governance through advocacy at global, regional, and national levels; generating reliable data and information on the availability and behavior of water resources; resource protection through effective reduction of wastewater and other waste discharging into freshwater supplies through regulation, investment, and innovation; water for food through stimulating research into improving the use of water in agriculture, increasing food production on the same area of land, and using less water; and increasing storage including via aquifer recharge, as a response to uncertainties in supply that are being aggravated by climate change.

Uncertainty on figures hampering food security efforts

More than 600 scientists gathered in the Netherlands for a global food security conference, described as the first of its kind.

The combination of poor harvests
and rising demand has increased
price volatility in global grain markets

Organisers said science could help end uncertainty surrounding efforts to meet the food needs of future generations.

They added that, until now, there were many policy debates on food security but there was no scientific forum for researchers to share knowledge.

The next food security conference will be held in the US in 2015.

"A really key message from the conference for us is that we have got lots of estimates about needs of population growth etc, but at the moment we are so uncertain of the exact numbers - the uncertainty is really very high," said conference co-chairman Ken Giller, professor of plant production systems at Wageningen University.

"We talk about the current population being seven billion, moving to 9.2 billion in 2050 and the estimate is that we need to increase production 70% or more.

"But there are many different ways of addressing that. If we don't know what the problem is then we can't get started in addressing them."

Appetite for change

Prof Giller said there was "unprecedented interest" among the scientific community when details of the conference was first announced.

"We did anticipate about 250-300 people , but we actually ended up with more than 900 abstracts being submitted," he told BBC News.

"The conference was basically sold out - we had 600 people and that was all we could accommodate."

He explained that the conference was designed to create a forum where representatives from the different branches of science could come together and discuss and debate the issues of global food security.

"We pulled together a science committee with the real aim to make the conference broad and to include all the main disciplines," he said.

"We had people on the science committee from economics, nutrition and we had people dealing with food waste, which is a very important topical issue."

Prof Giller said that current estimates suggested that 30-40% of the food produced was wasted and not eaten.

Other themes that were discussed at the conference included:

  • Nutritional security,
  • Sustainable intensification of food production systems,
  • Novel ways of feeding nine billion,
  • Agricultural production as feedstock for renewables.

The organisers hope that the outcomes from the four-day event in Noordwijkerhout, South Holland, will help focus the scientific world's contribution to the UN global policy system.

One of the UN's eight Millennium Development Goals (MDGs) was to "eradicate extreme poverty and hunger" by 2015, which included the target of halving - between 1990 and 2015 - the proportion of people suffering from hunger.

Assessments suggest the target is "within reach". However, a 2013 report on the progress of the MDGs warned that one in eight people remained chronically undernourished.

UN Secretary General Ban Ki-moon has announced that he wants to build on the MDGs, replacing them with a suite of Sustainable Development Goals that will run from 2015-2030.

He said one of his priorities was to "adopt globally agreed goals for food and nutrition security, mobilise all key stakeholders to provide support to smallholder farmers and food processors and bolster the resilience of communities and nations experiencing periodic food crises". More

Italy Calls for Food Security to Be U.N. Priority

ROME--Italy wants to shepherd efforts to make food security a priority for global policy makers, Prime Minister Enrico Letta said in his debut speech at the United Nations General Assembly Wednesday.

"We should address the root causes of the ills afflicting our world rather than limit ourselves to the side effects," Mr. Letta said. "The time has come to launch a new global consensus on food," he said.

In 2008, Italy, with limited financial firepower due to chronic fiscal problems, tried to make food security a signature theme at the Group of Eight summit in L'Aquila, Italy, prodding the largest economies to pledge as much as $15 billion for the cause. The global financial crisis then commanded vast public resources and attention, even though the serious spike in basic food prices that helped trigger the so-called Arab Spring sparked fear that easy monetary policies in developed economies would trigger runaway inflation in basic staples.

Commodity prices have since stabilized, according to a price-monitoring index set up by the UN's Food and Agricultural Organization in Rome.

Mr. Letta said that the 2015 Expo, or world's fair, in Milan should be a springboard for global initiatives, floating the idea that a multilateral pact might be reached there.

The Milan Expo, whose slogan is "Feeding the Planet, Energy for Life," aims to draw 20 million visitors interested in issues linked to sustainability. The event should be seized upon to create a Milan Protocol, modelled on the Kyoto Protocol of the late 1990s that covers environmental issues, with nutritional education, sustainable farming practices and food waste as its cardinal points, according to the Barilla Center for Food and Nutrition, a think tank backed by Barilla SpA, the pasta maker.

"Italy, with its rich food culture and heritage, is well-placed to show leadership in tackling the world's global food issues," said Danielle Nierenberg, an advisory board member at the Center.

Italy is also home to the U.N.'s main food-related agencies, the World Food Program, the International Fund for Agricultural Development, and the FAO, which after decades of advising farmers on how to boost yields is beginning to try to influence retail supply chains in an effort to reduce what it says is the waste of one-third of global food production.

Seeing Food As A Commons Opens Up Creative New Possibilities

What would the world look like if we began to re-conceptualize food as a commons? Jose Luis Vivero Pol of the Centre for Philosophy of Law at Catholic University of Louvain in Belgium has done just that in a recent essay, “Food as a Commons: Reframing the Narrative of the Food System.”

The piece is impressive for daring to imagine how the world’s estimated 668 million hungry people might eat, and how all of us would become healthier, if we treated more elements of the food production and distribution system as commons. Instead of managing food as a private good that can only be produced and allocated through markets, re-conceptualizing food as a commons helps us imagine “a more sustainable, fairer and farmer-centered food system,” writes Vivero Pol.

One reason that the commons reframing is so useful is that it helps us see the ubiquity of enclosures in the food system. We can begin to see the galloping privatization of farmland, water, energy and seeds. We can see the concentration of various food sectors and the higher prices and loss of consumer sovereignty that comes from oligopoly control.

Enclosure is snatching shared resources from us and preventing us from managing them to maximize access and good nutrition. This is often known these days as “resource grabbing,” as companies and national governments race to seize as many abundant, cheap natural resources as they can on an international scale. This is one reason for the many pernicious enclosures of land commons in Africa and Latin America in recent years. There is a huge exodus from traditional and indigenous lands as China, Saudi Arabia, Korea, hedge funds and others buy up natural resources. These enclosures are moving us “from diversity to uniformity, from complexity to homoegeneity, and from richness to impoverishment,” writes Vivero Pol.

Strangely, “no one has really questioned the nature of food as a private good, produced by private inputs or privately harvested in enclosed areas of the world." Yet asking such a question helps us to see why massive hunger can persist with food abundance. The ethic of “no money, no food” means that only those with sufficient "consumer demand" are entitled to food. And even then, good health is no guarantee because the industrialized food model actively promotes expensive processed foods that are either non-nutritious or actively harmful to our health, but more lucrative to companies.

It helps to remember that many aspects of food are already considered commons, notes Vivero Pol. For example, fish stocks, unpatented genetic resources, wild fruits, recipes, agricultural knowledge and food safety regulations cannot be owned and can be harvested and used by anyone or by bounded commons.

Most cultivated food, however, is generally a private good, which means that food is vulnerable to being traded, hoarded and sold for competing uses (e.g., biofuels, animal feed) if it can fetch more money. In the classic economists’ formulation, food that is privatized and commoditized can be made “excludable” and “rival,” and this in practice tends to override any moral entitlements or human rights claims over food.

This means that private control has enormous public consequences. If people go hungry because they can’t afford food, they suffer diet-related illnesses such as diabetes and heart disease. Their psychological health suffers. They may die of malnutrition. This of course has diverse economic, political and social effects that an economist would consider an unfortunate but inexorable “externality” for which buyers and sellers have no responsibility. But it is quite obvious that such are the predictable outcomes of the commoditization of food.

So how might we convert privately owned food production into more of a public good? (Vivero Pol uses “public good” and “commons” interchangeably, while acknowledging that the former term is used in economic contexts and the latter in sociological contexts. But I would suggest that the two terms should be emphatically separated to make clear that the commons has generative capacities and social grounding that a "public good" does not.)

First, we should apply the commons template to our food production system and enumerate the harms caused by enclosures. As Vivero Pol writes, these harms include: “excessive commodification of food, with high pricing, laws and private enclosure as main barriers to fully enjoying those vital resources”; irregular private land titling, land grabbing and land evictions…”; “excessive patents of life, biopiracy and patented GMOs”; “the concentration in agri-food chains in a few transnationals”; and enclosure schemes such as “the Carbon Sequestration Initiative,” the REDD+ and the Payment for Environmental Services.”

Once we regard food as a commons, we can begin to see that everybody ought to have a human right to food. “Another implication would be that food should be kept out of trade agreements dealing with pure private goods,” writes Vivero Pol. We would also need to develop an international legal framework to regulate food as a global level, and guarantee everyone a minimum amount of food as a “universal Basic Food Entitlement.” More

Will we ever see water footprint labels on consumer products?

That 130 litres of water goes into making your average coffee is a statistic that amazes most people. Even more surprising is that hardly anyone, even in the business community, has the foggiest idea how much water goes into manufacturing our favourite consumer products, from field to factory.

Seeking to address the dearth of information on the water required to produce a single product, from ready meals and soft drinks to t-shirts and electronic items, a variety of organisations have over the years floated the idea of water footprint labelling.

The general premise is that quantifying water inputs, like nutritional and calorie labels on food items, will help to influence purchasing habits, encouraging consumers to resist highly water intensive products. It would incentivise product manufacturers to scale back unnecessary waste and awaken consumer consciousness about water insecurity.

According to Dr Zafar Adeel, chair of UN-Water, the United Nations thinktank, not only does water footprint labelling make sense, but it is just around the corner. "People are often surprised and then ask, 'why didn't we know about this before?'

"I wouldn't call it a pipe dream," he says. "It will take five to 10 years for it to become fairly common."

Adeel suggests that a few pioneering companies may take the lead, rather than the government intervening. This in turn would spur industry-wide initiatives.

Growing consumer demand will be an important driver, he explains. "As we come up with new ways of measuring sustainability and the green economy, that will create back pressure on the private sector to come up with these schemes to provide more information."

Not everyone shares Adeel's optimism, however. Many critics regard any water footprint labelling scheme as a well-intentioned but ultimately meritless initiative, which risks further bamboozling already confused consumers.

Alistair Knox, chairman of the Association of Suppliers to the British Clothing Industry, is one influential voice in the clothing industry to pour cold water on the idea. The proposal is just not on the clothing industry's agenda, he says, and is far below issues such as the durability of garments or energy usage.

"It would be a bit pointless. There is already a huge amount of information on garment labels that people very rarely, if ever, look at," he says, adding that the industry would regard any serious proposal as a "little bit bizarre".

In Knox's view, any figure assigned to a clothing product for water usage is "dubious" as it is "from difficult to impossible" to calculate accurately beyond a generic average. He uses the example of a cotton yarn, the fibres of which may have come from several regions, each of which may have had different irrigation systems.

"How are you going to average that? Whatever number you come up with is just somebody's thumb in the air." The same could be said for many other consumer industries, such as electronic goods.

Knox also challenges the idea that water volume use is an important consideration for consumers. "The bottom line is that water recycles … Where is that water now? It's back in the system."

The sense that water volume labelling is too simplistic is shared by Felix Ockborn, environmental sustainability coordinator for water at high-street clothing retailer H&M. While Ockborn welcomes product scoring on sustainability performance, he says it is just as vital to consider the context of the water consumption in any labelling system.

"Only providing a volumetric product footprint would be misguiding if it does not incorporate where the water was taken from," he says. "What is most important is what we and other companies do to ensure that water is used responsibly."

Simon Davidoff, senior director of strategy for industrial services at Siemens, supports the idea of water footprint labels alongside energy use indicators. Technological advances mean it is relatively easy to quantify consumption and wastage in factory environments, he says.

Like Adeel, Davidoff believes water footprint labels are now inevitable. "Consumers will demand it," he says. The challenge will be in agreeing how far back companies should go to measure water inputs. More

Climate change may reduce crop production by 50% in some countries, says environmentalist

A former Bolivian Ambassador to United Nations said this in Lagos on Friday.

Climate change could reduce yields from rain-fed agriculture by up to 50 per cent in some countries by 2020.

Pablo Solon, former Bolivian Ambassador to United Nations, stated this, Friday, at the inaugural Health of Mother Earth Foundation (HOMEF)’s Sustainable Academy in Lagos.

“We have to recognize that we are part of nature, that our future is linked with the future of earth,” said Mr. Solon, Executive Director, Focus on the Global South.

Two-thirds of all proven fossil fuel reserves would have to be left “unburned” if global warming will be held for two degrees Celsius, according to the International Energy Agency.

Mr. Solon explained the magnitude of the temperature rise by stating that a one degree rise in the normal body temperature could lead to fever.

The event themed ‘Climate Change and the Looming Food Crisis’ had already concluded two sessions, earlier in the week, in Abuja and Benin City.

Nnimmo Bassey, HOMEF’s Director, said that global warming has become a major concern in Nigeria and the rest of the world, with large numbers of people still ignorant about it.

“No doubt people recognize that weather events such as rainfall and flooding are getting more intense. They can even tell you the rhythms of the weather have become unpredictable,” said Mr. Bassey.

“However, when it comes to saying what is responsible for climate change, the answers taper out. If we do not know the cause and those responsible, it is doubtful that we can solve the problem,” he added.

Mr. Bassey said that effective communication of climate change and the looming food crisis will help “unpack the problem.”

“We hope that concepts like Reducing Emissions from Deforestation and Forest Degradation in developing countries (REDD), Clean Development Mechanism (CDM), and other market-based false solutions would be exposed for what they are,” Mr. Bassey said.

“Projects like Eko Atlantic City must be interrogated as a climate challenge, not a solution, recognizing the fact of sea level rise and the low-lying nature of Nigeria’s vulnerable coastline,” he added.

Mr. Bassey further stated that temperature increases of the magnitude currently experienced was now a possibility because of refusal of polluting nations to commit to measurable and verifiable emissions cut.

“Africa is poised to heat up much more than other regions,” Mr. Bassey continued.

“Continuous temperature rise because of lack of commitment of nations to cut emissions at source will translate to the roasting of Africa, an already very vulnerable continent.

“Food production capacity will also be diminished, exposing the continent to great danger,” he added. More
