"In a sustainable community, resource consumption is balanced by resources assimilated by the ecosystem. The sustainability of a community is largely determined by the web of resources providing its food, fiber, water, and energy needs and by the ability of natural systems to process its wastes. A community is unsustainable if it consumes resources faster than they can be renewed, produces more wastes than natural systems can process or relies upon distant sources for its basic needs."

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

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

Cary Fowler on Food Security - TED Talk

Cary Fowler served as the Executive Director of the Global Crop Diversity Trust from 2005 to 2012.[8] The trust's mandate is to ensure "the conservation and availability of crop diversity for food security worldwide." Fowler was influential in the creation of the Svalbard Global Seed Vault, which currently houses samples of more than 783,000 distinct crop varieties. He stepped down as Executive Director of the trust in late 2012 but continues to serve in an advisory role and chairs the International Advisory Council of the Svalbard Global Seed Vault.[4][8]

Working with partner genebanks in 71 countries during Fowler's tenure as Executive Director, the Trust helped rescue 83,393 unique crop varieties from extinction. It sponsored more than 40 projects to screen crop collections for important traits such as heat and drought tolerance. In partnership with the USDA, a state-of-the-art genebank management system ("GRIN-Global") was developed and made available to 38 genebanks internationally, and the first ever global portal to accession (sample) level information (Genesys)[9] was launched. The Trust's endowment grew more than $100 million to $134 million, and total funds raised surpassed $200 million.[10][11]

By the end of Fowler's tenure, the Trust concluded three major agreements intended to protect and conserve crop diversity: with the Millennium Seed Bank of Kew Gardens,[12] the indigenous communities in the Andes,[13] and the international genebanks of the Consultive Group on International Agricultural Research (CGIAR).[14]

One example given here is for South Asia where we must pay attention from a food security perspective. Editor

‘China a concern for South and Central Asia’s water security’

New Delhi: With China building a “cascade of dams” in the upper reaches of rivers that flow into Central and South Asia and drawing large amounts of water to sustain its economy and people, there is a need to engage the Asian giant at bilateral and multilateral fora on the issue of water that is fast becoming a scarce and contentious commodity, said diplomats and experts here.

Himalayas - Source of S. Asia's water

Addressing a round table on “Regional Water Security and Riverine Disputes: Issues Common to Central and South Asia” here Thursday, speakers, including ambassadors from Central Asian countries and other domain experts, also said that there is a need for Track II dialogue between civil society activists of countries and for transparency in sharing of hydro information in order to resolve the issues concerning sharing of water.

Leading strategic expert Brahma Chellaney said Central and South Asia share common water security issues. He said China is “happily placed” as it is home to the largest number of trans-border rivers, which all originate from the Tibetan Plateau and the Xinjiang region. Chellaney said China’s “annexation” of Tibetan Plateau and Xinjiang “changed the water discourse” for the people of South and Central Asia.

Chellaney, who is professor of strategic studies at the Centre for Policy Research, said China “is an issue of concern in South Asia and Central Asia… China is building a cascade of dams just before the rivers flow out of its territory.”

Ajay Bisaria, joint secretary in the Eurasia division of the external affairs ministry, said that India stands to benefit from the Central Asia South Asia Electricity Transmission and Trade Project, better known as CASA-1000, a new electricity transmission system to connect the countries of hydropower producing countries of Kyrgyzstan and Tajikistan with Afghanistan and Pakistan.

Ashok Sajjanhar, former ambassador to Kazakhstan, said the Aral Sea from being a lake of plenty with fish, birds and wildlife, has turned into an “ecological disaster” with very high salinity and water level shrunk massively. The Aral Sea is a lake lying between Kazakhstan and Uzbekistan. Sajjanhar said the issue of water distribution and water management between countries sharing water bodies is very crucial.

Rajiv Dogra, former ambassador, said the Central Asian water bodies were once clear blue and pristine, but have shrunk due to overuse.

“A drop of water is a grain of gold”, is the value placed on water in Turkmenistan, said the country’s Ambassador Parakhat Hommadovich Durdyev at the seminar held at the India International Centre and organised by the think tank Society for Policy Studies in collaboration with Asia News Agency.

William Young, Lead Resource, South Asian Water Initiative, World Bank, said the Ganga plains is inhabited by 600 million people, which shows the dependency on the river. He said the World Bank was looking to establish dialogues for the Ganga and Brahmaputra basin river countries.

Sanjoy Hazarika, director of Centre for North East Studies at Jamia Millia Islamia, said the run of river dams that China was building on the Brahmaputra removes the fertile silt from the river water when it is released downstream into India, thereby harming agriculture and leading to climate change.

Hazarika also slammed the idea of interlinking of rivers being proposed in India, terming it a disastrous idea. More

Can The World Feed China? by Lester Brown

Overnight, China has become a leading world grain importer, set to buy a staggering 22 million tons in the 2013–14 trade year, according to the latest U.S. Department of Agriculture projections. As recently as 2006—just eight years ago—China had a grain surplus and was exporting 10 million tons. What caused this dramatic shift?

Lester Brown

It wasn’t until 20 years ago, after I wrote an article entitled “Who Will Feed China?”, that I began to fully appreciate what a sensitive political issue food security was to the Chinese. The country’s leaders were all survivors of the Great Famine of 1959–61, when some 36 million people starved to death. Yet while the Chinese government was publicly critical of my questioning the country’s ability to feed itself, it began quietly reforming its agriculture. Among other things, Beijing adopted a policy of grain self-sufficiency, an initiative that is now faltering.

Since 2006, China’s grain use has been climbing by 17 million tons per year. (See data.) For perspective, this compares with Australia’s annual wheat harvest of 24 million tons. With population growth slowing, this rise in grain use is largely the result of China’s huge population moving up the food chain and consuming more grain-based meat, milk, and eggs.

In 2013, the world consumed an estimated 107 million tons of pork—half of which was eaten in China. China’s 1.4 billion people now consume six times as much pork as the United States does. Even with its recent surge in pork, however, China’s overall meat intake per person still totals only 120 pounds per year, scarcely half the 235 pounds in the United States. But, the Chinese, like so many others around the globe, aspire to an American lifestyle. To consume meat like Americans do, China would need to roughly double its annual meat supply from 80 million tons to 160 million tons. Using the rule of thumb of three to four pounds of grain to produce one pound of pork, an additional 80 million tons of pork would require at least 240 million tons of feedgrain.

Where will this grain come from? Farmers in China are losing irrigation water as aquifers are depleted. The water table under the North China Plain, an area that produces half of the country’s wheat and a third of its corn, is falling fast, by over 10 feet per year in some areas. Meanwhile, water supplies are being diverted to nonfarm uses and cropland is being lost to urban and industrial construction. With China’s grain yield already among the highest in the world, the potential for China to increase production within its own borders is limited.

The 2013 purchase by a Chinese conglomerate of the American firm Smithfield Foods Inc., the world’s largest pig-growing and pork-processing company, was really a pork security move. So, too, is China’s deal with Ukraine to provide $3 billion in loans in exchange for corn, as well as negotiations with Ukrainian companies for access to land. Such moves by China exemplify the new geopolitics of food scarcity that affects us all.

China is not alone in the scramble for food. An estimated 2 billion people in other countries are also moving up the food chain, consuming more grain-intensive livestock products. The combination of population growth, rising affluence, and the conversion of one third of the U.S. grain harvest into ethanol to fuel cars is expanding the world demand for grain by a record 43 million tons per year, double the annual growth of a decade ago.

The world’s farmers are struggling to keep pace. When grain supplies tightened in times past, prices rose and farmers responded by producing more. Now the situation is far more complex. Water shortages, soil erosion, plateauing crop yields in agriculturally advanced countries, and climate change pose mounting threats to production.

As China imports increasing quantities of grain, it is competing directly with scores of other grain-importing countries, such as Japan, Mexico, and Egypt. The result will be a worldwide rise in food prices. Those living on the lower rungs of the global economic ladder—people who are already struggling just to survive—will find it even more difficult to get by. Low-income families trapped by food price inflation will be unable to afford enough food to eat every day.

The world is transitioning from an era of abundance to one dominated by scarcity. China’s turn to the outside world for massive quantities of grain is forcing us to recognize that we are in trouble on the food front. Can we reverse the trends that are tightening food supplies, or is the world moving toward a future of rising food prices and political unrest? More

Brazil rations water in 140 cities amid worst drought in decades

Over 140 Brazilian cities have been pushed to ration water during the worst drought on record, according to a survey conducted by the country's leading newspaper. Some neighborhoods only receive water once every three days.

Water is being rationed to nearly 6 million people living in a total of 142 cities across 11 states in Brazil, the world's leading exporter of soybeans, coffee, orange juice, sugar and beef. Water supply companies told the Folha de S. Paulo newspaper that the country's reservoirs, rivers and streams are the driest they have been in 20 years. A record heat wave could raise energy prices and damage crops.

Some neighborhoods in the city of Itu in Sao Paulo state (which accounts for one-quarter of Brazil's population and one-third of its GDP), only receive water once every three days, for a total of 13 hours.

Brazil's water utility company Sabesp said on its website that the Cantareira water system (the largest of the six that provide water to nearly half of the 20 million people living in the metropolitan area of Sao Paulo) is at less than 19 percent of its capacity of 1 trillion liters. The company described the situation at Cantareira as"critical": the amount of rain registered in the month to January was the lowest in 84 years. Sabesp said the other five water supply systems in Sao Paulo's metropolitan area were normal for this time of year, however.

The PCJ Consorcio water association said the area would have to see 17 millimeters of rain a day for two months until Cantareira's water level recovers to 50 percent of its capacity.

Average reservoir levels in the southeast and central-west regions, which account for up to three-thirds of Brazil's hydroelectric power generation, fell to 41 percent in late January.

January was the hottest month on record in parts of the country, including in Sao Paulo. The heat, plus a severe drought, has raised concerns over growing water shortages and crop damage. According to Brazil's national meteorological institute INMET, Sao Paulo's average maximum daily temperature so far this year was 31.9 degrees Celsius (89.4 degrees Fahrenheit), a degree hotter than the previous January record and surpassing February 1984 as the city's hottest month ever.

According to the state meteorological agency in Ceara state, the northeast of the country is also experiencing its worst drought in at least 50 years. Hundreds of thousands of cattle have died from heat exhaustion, and farmers are getting desperate. "I have never seen a drought like this,” Ulisses de Sousa Ferraz, an 85-year-old farmer in Pernambuco state, told Reuters, adding that he has lost 50 cows. “Everything has dried up." More

The Water Levels Of The Middle East’s Biggest Lake Have Dropped 95 Percent In Two Decades

According to the local environmental office in Iran, only five percent of the water remains in the biggest lake in the Middle East.

Lake Urmia sits in the far northwest corner of Iran, and was once the sixth largest saltwater lake in the world — slightly bigger than Utah’s Great Salt Lake. It’s relatively shallow, so the water drop has exposed huge tracts of land. Hamid Ranaghadr, an Iranian environmental official, told the New York Times that areas of the lake that were once under 30 feet of water are now dry and dusty lake beds. “We just emptied it out,” he said.

Being saltwater, Lake Urmia was never fit for drinking water or agriculture. But its collapse is indicative of the way climate change and poor water management has driven Iran into a potentially catastrophic water shortage. Dam construction recently increased throughout the country, both to provide badly needed electricity and water supplies for irrigation. But that’s also diverted massive amounts of the freshwater that formerly flowed into Lake Urmia. Other major rivers throughout the country have gone dry, and the dust from the riverbeds and the salt from Lake Urmia’s dried basin are now a form of pollution unto themselves. (Four of the world’s ten most polluted cities can be found in Iran.) Major cities around the country — including the capital of Tehran, home to 22 million — are making contingency plans for rationing. Iranian President Hassan Rouhani recently named water as a national security issue, and demonstrations and riots over water supplies have already erupted.

The collapse began in the mid-1990s. One local villager told the Times that he noticed the shoreline receding two decades ago, and now it’s no longer visible from his community. According to a 2012 study by the United Nations, 65 percent of the decline can be chalked up to climate change and the diversion of surface water cutting inflow to the lake. Another 25 percent was due to dams, and 10 percent was due to decreased rainfall over the lake itself.

A long drought in Iran ended two years ago, but the recent boost to rainfall has not been able to offset the other effects on the lake. Average temperatures around Lake Urmia rose three degrees in just the past ten years. In Pakistan, which sits along Iran’s southeast border, has seen its snowmelt and river flow reduced by climate change. That’s led to both political strife domestically, and to a strained relationship with India, which is building dams along the Indus River — Pakistan’s main source of freshwater. And research from the the Potsdam Institute for Climate Impact Research in Germany found water resources in northwest Iran could drop 50 percent should global warming increase by just 2°C.

The world is currently on track to blow past 2°C by the end of the century.

After the water is diverted away, a lot of it is used recklessly. Ranaghadr and other experts point to inefficient irrigation techniques such as spraying, which allows most of the water to evaporate uselessly from the fields. His department calculated that around 90 percent of the water that should flow into Lake Urmia is sprayed instead, and President Rouhani has estimated that Iran’s uses 92 percent of its water for agriculture, versus 80 percent in the United States.

“They turn open the tap, flood the land, without understanding that in our climate most of the water evaporates that way,” Ali Reza Seyed Ghoreishi, a member of the local water management council, told the Times. “We need to educate the farmers.”

The Iranian government also attempted to promote agriculture by breaking large landholdings into smaller properties. Most of the new owners promptly dug new wells to supply their crops, draining the groundwater. “There are around 30,000 legally dug wells and an equal amount of illegal wells,” said Seyed Ghoreishi. “As the water is becoming less, they have to dig deeper and deeper.”

Efficient water management generally requires either a working market where prices keep supply and demand tethered, or well-developed public institutions to manage the supply. Unfortunately, the developing world often has neither. A coalition of groups over the United Nations tried to quantify, in dollar terms, water use around the globe in April of 2013. They found West Asia, where Iran can found,was the third-most costly regional user of water in the world, right behind East Asia and North Africa.

Thanks to budget choices and international sanctions, Iran has not made any money available to restoration efforts for Lake Urmia. Iranian officials told the Times the lake is, at this point, probably unsalvageable.

Water security in the Kingdom of Saudi Arabia … a far-fetched dream?

DAMMAM – Environmental and water experts have warned that water security might be a far-reaching dream for the Kingdom.
Limited water resources such as groundwater are being depleted by greedy farmers who care about nothing but profits, they said. The claimed nuclear energy can help desalinate seawater and save the country from a looming disaster that future generations will experience. Al-Riyadh daily asked the experts about the challenges the state faces in ensuring water security.

Precious resource

Dr. Asad Abu Ruzaizah, president of the Saudi Society for Environment Sciences, said the country is running out of groundwater at an alarming rate. He stressed the important role citizens can play to mitigate the enormity of the problem and conserve this valuable resource. “Some people are not really aware that we have a water security problem,” Ruzaizah said. “The government spends a huge amount of money on the desalination process but this causes a tremendous negative effect on the environment.
“Moreover, strategic water reserves are poor in the Kingdom and other GCC countries and this fact makes the water problem a huge challenge for these countries.
“We have a poor water authority and low awareness levels regarding the importance of saving water. “More funding should go into developing and managing water resources and searching constantly for new sources.
“The water authority and other water agencies should be developed to deal better with this issue and achieve sustainable development for the next generation.”

New regulations to manage current reserve

Dr. Muhammad Al-Ghamdi, professor of King Faisal University’s School of Agricultural Sciences, disagrees with Ruzaizah. “Everyone is saying let’s find new water resources instead of searching for regulations that can lead to the wise management of current resources,” Al-Ghamdi said. “Unfortunately, there are no clear plans, programs, or strategies to help us achieve water security.” He said he wondered how this problem would be solved while farmers, led by greed, continue to waste groundwater and mismanage limited water resources. “The sad thing is facts and statistics indicate that our groundwater problem is getting worse every year. “I’m worried the next generations will encounter insurmountable problems solving this issue.”
Dr. Ali Ishqi, ecology professor at King Abdulaziz University, said the Arabian Peninsula has a severe water shortage. Ninety percent of its area is barren desert land while green areas account for 2 percent of the total area. Ishqi believed that mismanagement of water resources has largely exacerbated groundwater shortages.
He said the only strategy that can end this looming crisis is to make use of nuclear energy.
“The use of nuclear reactors is the best choice for seawater desalination.
“Solar energy is not. “To meet the water needs of a small city population, you will need to have so many solar cells on a very large area.”

Rainwater harvesting is the solution

Abdullah Al-Rasheed, economist, said the only option available to solve this crisis is to set up a national authority for rainwater harvesting, where rainwater is collected and used for irrigation, drinking, and other purposes. The next upcoming war will be for water, Al-Rasheed claimed.
He quoted a feature that National Geographic carried a while ago on the water issue.
The Kingdom’s groundwater resources used to stand at 500 cubic kilometers 40 years ago, according to the feature. So far the country has used 400 cubic kilometers, which means that one generation has consumed 80 percent of the country’s resources. The feature said the Kingdom now has no choice but to use seawater because the remaining groundwater will probably be consumed in a few years. Al-Rasheed said he hoped that the statistics mentioned in the feature were not true. “One thing remains true: we have squandered our groundwater and used it for farming purposes. “There is no point now of crying over spilled milk. “It’s high time we utilized rainwater.”
Al-Rasheed said every year there is 150 billion to 250 billion cubic meters of rainfall in the Kingdom, while the amount of desalinated water the public consumes annually is 3 billion. “This is a small amount compared to the huge quantity of rainwater available for us.” 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.

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

Human Influence On Climate Clear, IPCC Report Says

It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century. The evidence for this has grown, thanks to more and better observations, an improved understanding of the climate system response and improved climate models.

Warming in the climate system is unequivocal and since 1950 many changes have been observed throughout the climate system that are unprecedented over decades to millennia. Each of the last three decades has been successively warmer at Earth's surface than any preceding decade since 1850, reports the Summary for Policymakers of the IPCC Working Group I assessment report, Climate Change 2013: the Physical Science Basis, approved on Friday by member governments of the IPCC in Stockholm, Sweden.

"Observations of changes in the climate system are based on multiple lines of independent evidence. Our assessment of the science finds that the atmosphere and ocean have warmed, the amount of snow and ice has diminished, the global mean sea level has risen and the concentrations of greenhouse gases have increased," said Qin Dahe, Co-Chair of IPCC Working Group I.

Thomas Stocker, the other Co-Chair of Working Group I said: "Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system. Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions."

"Global surface temperature change for the end of the 21st century is projected to be likely to exceed 1.5°C relative to 1850 to 1900 in all but the lowest scenario considered, and likely to exceed 2°C for the two high scenarios," said Co-Chair Thomas Stocker. "Heat waves are very likely to occur more frequently and last longer. As Earth warms, we expect to see currently wet regions receiving more rainfall, and dry regions receiving less, although there will be exceptions," he added.

Projections of climate change are based on a new set of four scenarios of future greenhouse gas concentrations and aerosols, spanning a wide range of possible futures. The Working Group I report assessed global and regional-scale climate change for the early, mid-, and later 21st century.

"As the ocean warms, and glaciers and ice sheets reduce, global mean sea level will continue to rise, but at a faster rate than we have experienced over the past 40 years," said Co-Chair Qin Dahe. The report finds with high confidence that ocean warming dominates the increase in energy stored in the climate system, accounting for more than 90% of the energy accumulated between 1971 and 2010.

Co-Chair Thomas Stocker concluded: "As a result of our past, present and expected future emissions of CO2, we are committed to climate change, and effects will persist for many centuries even if emissions of CO2 stop."

Rajendra Pachauri, Chair of the IPCC, said: "This Working Group I Summary for Policymakers provides important insights into the scientific basis of climate change. It provides a firm foundation for considerations of the impacts of climate change on human and natural systems and ways to meet the challenge of climate change." These are among the aspects assessed in the contributions of Working Group II and Working Group III to be released in March and April 2014. The IPCC Fifth Assessment Report cycle concludes with the publication of its Synthesis Report in October 2014.

"I would like to thank the Co-Chairs of Working Group I and the hundreds of scientists and experts who served as authors and review editors for producing a comprehensive and scientifically robust summary. I also express my thanks to the more than one thousand expert reviewers worldwide for contributing their expertise in preparation of this assessment," said IPCC Chair Pachauri.
