Climate change and water mismanagement parch Egypt

Climate change, a fast growing population, ill-designed infrastructure, high levels of pollution and lack of law enforcement have made Egypt a country thirsty for water — both in terms of quantity and quality.

The River Nile, which is considered poor by many experts and hydrologists, lies at lower altitude than the rest of the country. Massive electric pumps extract the water from the river’s bed and canals and direct it to industry, agriculture and for individual water use.

A significant portion of the water contained in Lake Nasser’s 5,000 square kilometer basin is lost to evaporation, while old networks of leaking pipes also deprive the country of satisfactory access to its most important resource: water.

In order to debate water scarcity in Egypt, its causes, and how climate change makes the issue more pressing than ever, as well as looking to solutions, a panel of experts were invited to participate in the 13th Cairo Climate Talk last week entitled “Growing Thirst: Sustainable Water Solutions for Egypt.”

Tarek Kotb, the First Assistant Minister in the Ministry of Water Resources and Irrigation, and a member of the panel discussion, talked about the dwindling water share per capita with a sense of urgency. “Every year, the Egyptian population grows by 1.8 million, while the annual quota of Nile water allocated to Egypt, 55 billion cubic meters, has remained unchanged since the 1959 Nile Water Agreement,” he says.

While Egyptians in the 1960s could enjoy a water share per capita of 2800 cubic meters for all purposes, the current share has dropped to 660 cubic meters today—below the international standard defining water poverty of 1000 cubic meters.

Kotb estimates that Egypt is gradually going to leave the stage of water scarcity and enter a phase of drastic water stress in the next 40 years, if no sustainable water management is put in place.

“By 2050, there will be about 160 million Egyptians and only 370 cubic meters of water per capita,” he says. While Egypt has other options for its water needs, such as tapping into groundwater basins and desalinating sea-water, the bulk of water is still extracted from the Nile, leading to longstanding tensions with the other Nile basin countries.

The treaty signed under colonial rule in 1959 granted Egypt and Sudan most of the Nile water share, while upstream countries were given access to a very small allocation of water. Lama al-Hatow, a hydrologist and one of the founders of the Water Institute for the Nile (WIN) condemns Egypt’s historical and ongoing hydro hegemony, by which the country claims its entitlement to benefit from most of the Nile water.

“A lot of science has been published on how not to lose water if the Ethiopian Millennium Dam is built, but it is not given much attention by the politicians,” Hatow says. “The upstream countries have the right to develop,” she says, “and there are ways to make it happen without Egypt losing water.”

She adds that preventing water evaporation in Lake Nasser could even increase Egypt’s water share.

Kotb responding to her remarks, saying that Egypt is investing millions of dollars in Sudan, South Sudan and Ethiopia to overcome losses due to evaporation in marshes and basins. “We don’t deny these countries’ right to development; actually, we help them,” he said.

Claudia Bürkin, the Water Sector Coordinator for the German Development Cooperation and Senior Programme Manager at KfW Development Bank, explains that Egypt’s water resources face two main challenges: water loss and bad quality.

“Egypt loses about 50% of its freshwater through poor maintenance of supplies and distribution problems, and the water is polluted,” she says, stressing that a significant number of diseases are water borne. Polluted water also affects the ecosystems’ balance, the soil quality, and seeps into the aquifers. “Egypt needs to set up strong standards for water quality and control the drainage nutrients, pesticides and waste found in the water.”

Kotb admits that while most of the issues and potential solutions have been identified by the government, much needs to be done in terms of implementation of existing laws and stronger cooperation between ministries.

“Water management is not the mandate of the Ministry of Water Resources and Irrigation exclusively, which makes the implementation process so much harder,” he says.

A National Water Resource Plan was established a few years ago, Kotb says, to curb the amount of pollution in the Nile emanating from cruise boats, factories, industries and villagers deprived of a waste management system. As part of this, he explains, factories located close to the Nile or the canals have been moved further away from the water streams, and new industries will be prevented from setting up a plant within 20km from the water.

“Law 48 on pollution has been reviewed and the penalties will be tougher,” he says. Meanwhile, Hatow argues that enforcing stronger penalties is not the solution to prevent farmers from polluting.

“Instead of punishing them, we should give farmers incentives to make better use of water, and provide them with premium crops,” she says.

The conversation then shifted to the effects of climate change, which can already be felt in the Northern part of the Delta and in the Mediterranean coastal cities of Damietta and Rosetta. The gradual rise in sea levels taking place turns fields into barren land unfit for agriculture, and the sea water that infiltrates the Nile is reaching further and further away from the coast.

“In order to keep a good yield and maintain agricultural production,” says Kotb, “we need to use more fresh water to combat rising temperatures.”

Lama’s take on how to combat climate change is quite different from this. “We need to study community based resilience techniques to figure out how local and indigenous knowledge can provide answers and climate resilience.”

Pakistan and UK Invite Climate scientist Schellnhuber to brief UN Security Council

02/15/2013 - As climate change starts being recognized as a security issue on the highest international levels, Pakistan and the United Kingdom have asked Hans Joachim Schellnhuber of the Potsdam Institute for Climate Impact Research (PIK) to speak at an in-depth discussion event for the UN Security Council members. The meeting aims at addressing “potential threats posed by possible adverse effects of climate change to the maintenance of international peace and security”. It will take place on February 15th at the UN headquarters in New York City. Secretary-General Ban Ki-moon plans to attend.

UN HQ

“With unabated greenhouse-gas emissions, humankind would venture into an uncertain future that is much hotter than ever before in its history – so from a scientist’s perspective, climate change is a global risk multiplier,” says Schellnhuber, director of PIK and chair of the Scientific Advisory Council on Global Change (WBGU) for the German government. Many millions of people could be affected by severe climate change impacts. They range from sea-level rise that increases the frequency of severe coastal flooding, to changes in atmospheric circulation patterns that could trigger, e.g., monsoon failures.

“Most remarkably, Pakistan and the UK together have called this meeting – illustrating, by action, that climate change is an issue for both developing and industrialized countries,” Schellnhuber says.

Climate change impacts might trigger social tipping dynamics

If the international community allows global mean temperature to rise way beyond the 2-degree limit that it agreed upon, major environmental tipping points could be crossed. “The Earth system shows a nonlinear response to greenhouse-gas emissions, so elements like the Amazon rainforest could react drastically if some warming thresholds are passed. This in turn might result in tipping international relations from a situation in which an initial increase of cooperation in face of a crisis shifts into a fierce competition for scarce natural resources, like food,” argues Schellnhuber. “However, another kind of social tipping dynamics is imaginable as well – with states, and people, becoming aware of the dangers ahead, and starting the great transformation towards sustainability.” One small example for this might be the German Energiewende (a rapid decarbonization of the national energy system).

Schellnhuber is the only scientist invited to the meeting. The other eminent speakers are Tony DeBrum, Minister-in-assistance to the President of the Marshall Islands, Rachel Kyte, Vice President of Sustainable Development at the World Bank, and Gyan Acharya, Under-Secretary General and High Representative of the least developed countries. Some of the issues to be debated are climate change impacts on food security, sustaining cooperative management of freshwater supply in the face of glacial melting and reduced runoff, and possible large-scale displacements of people across borders.

Corporations Grabbing Land and Water Overseas

As a growing population stresses the world's food and water supplies, corporations and investors in wealthy countries are buying up foreign farmland and the freshwater perks that come with it.

From Sudan to Indonesia, most of the land lies in poverty-stricken regions, so experts warn that this widespread purchasing could expand the gap between developed and developing countries.

The “water grabbing” by corporations amounts to 454 billion cubic meters per year globally, according to a new study by environmental scientists. That’s about 5 percent of the water the world uses annually.

Investors from seven countries – the United States, United Arab Emirates, India, United Kingdom, Egypt, China and Israel – accounted for 60 percent of the water acquired under these deals.

Most purchasers are agricultural, biofuel and timber investors. Some of the more active buyers in the United States, which leads the pack in number of deals, include multinational investors Nile Trading and Development, BHP Billiton, Unitech and media magnate Ted Turner, according to the study published last month.

Wendy Wolford, a professor at Cornell University who studies political and social impacts of international land deals, said while it is difficult to tease out investor motives, they “don’t grab land in places without access to water.” Some countries – including Indonesia, the Philippines and the Democratic Republic of Congo – had large amounts of water rights grabbed because they’re countries with a lot of rainfall.

Since 2000, 1,217 deals have taken place, which transferred over 205 million acres of land, according to the public database Land Matrix. About 62 percent of these deals were in Africa – totaling about 138 million acres, roughly the size of two Arizonas.

For countries reliant on farming and already suffering from poverty, the potential impacts are huge, said Paolo D’Odorico, a University of Virginia professor and co-author of the new report that estimates the water supplies at stake. About 66 percent of the total deals are in countries with high hunger rates.

“In many of these countries, the sum of the water being grabbed would be enough to eliminate malnourishment,” said D’Odorico, who collaborated with scientists from Italy’s Polytechnic University of Milan.

Wolford said there is danger that local people – especially in places like sub-Saharan Africa – are not aware of land purchases and how it could affect their way of life.

“That’s probably the biggest problem – people could have gathered timber from the woods or lived downstream of the land grabbed,” Wolford said. “These things could be taken away without them knowing what happened.”

Food crisis, biofuels spur “grabbing”

Such land deals are often derisively dubbed “land grabbing,” which D’Odorico defines as a deal for about 500 acres or more that converts an environmentally important area currently used by local people to commercial production. More

 

 

Will Climate Change Affect The Pakistani Apple Crop?

Indian Arunachal apples losing taste due to climate change

Popular for its sweetness, apples produced in the Himalayan state of Arunachal Pradesh are now gradually losing their taste and even turning sour as a result of climate change.

With the weather becoming erratic and a clear variation in temperature, snowfall and rainfall pattern being recorded, apple crops are no more getting the appropriate agro-climatic requirements, horticulturists and climate change experts say.

For optimum growth and fruiting, apple trees need 100-125 cm of annual rainfall, evenly distributed during the growing season.

In the last few years, there has been an unprecedented increase in the intensity of rainfall as well as cloudbursts in the north-eastern state. Farmers of the remote Mechuka valley in West Siang district, a few kms away from the China border, complain that 15-20 years ago the apples they produced were sweet, but now the fruits taste sour.

"Earlier apples used to flower only once in a year during February. Now they flower twice a year, in late March and September. The flowers that bloom in March produce fruits, while those that bloom in September do not produce any fruits," Dr Sanjeeb Bharali from the Indian Council of Agricultural Research (Division of Natural Resource Management), Meghalaya said.

Apple cultivation in Arunachal Pradesh is mainly concentrated in Tawang, West Kameng and Lower Subansiri districts, though the fruit is of late being grown in West Siang and Anjaw districts too.

During 2009 -10 the state recorded a total apple production of about 10,000 tonnes.

Admitting the effect of climate change on the production of apples, Dr Ahmed said the temperate fruit also needs a temperature of 20-25 degrees C during the growing season.

But with the weather becoming unpredictable and erratic, sometimes the temperature is more than that or sometimes less. All this affects the crop as its survival is dependent completely on the weather, he said.

Dr Prasanna K Samal, scientist in-charge at the G B Pant Institute of Himalayan Environment and Development in Itanagar, said increased warming is shifting agriculture calendar while inviting new pests and crop diseases.

A research by geologist S K Patnaik of Arunachal's Rajiv Gandhi University shows that the minimum temperature in the last 100 years has been decreasing while the maximum is showing an increasing trend. More

 

Satellite Tracking of Middle East Aquifers Points to the End of ‘Data Denial’

Jay Famiglietti, one of the authors of an important new study on the rapid depletion of aquifers under the Tigris and Euphrates river basins, has posted an excellent overview of the work and its context for policy, and noted that he and other authors are preparing for a two-week “water diplomacy” tour to discuss their findings in the affected region.

The project shows how improving systems for observing and analyzing environmental trends are brightening prospects for better management of resources and risks in struggling regions — even when governments might not want the information revealed. This is as true for forests as it is here for water supplies.

Here are some notable excerpts from Famiglietti’s post, which is particularly notable given President Obama’s planned visit to the Middle East this spring:

Worse to come:

Our team’s expectation is that the water situation in the Middle East will only degrade with time, primarily due to climate change. The best available science indicates that the arid and semi-arid regions of the world will become even more so: the dry areas of the world will become drier (while conversely, the wet areas will become wetter). Consequences for the Middle East include more prolonged drought, which means that the underground aquifers that store the region’s groundwater will not be replenished during our lifetimes, nor during those of future generations.

Management and transparency:

We cannot reverse climate change and its impact on water availability, but we can and must do a far better job with water management, including the modernization of national and international water policy. Our research and its implications point to the following critical needs, not only for the Middle East, but in all regions of the world where groundwater resources are in decline.

First, it’s high time for groundwater to be included under the water management umbrella. In most of the world, groundwater pumping is unmonitored and unregulated.

It is as true in much of the U. S. as it is in the Middle East. That’s no different than making withdrawals from a savings account without keeping track of the amount or the remaining balance: irresponsible without question, and a recipe for disaster when multiple account holders are acting independently.

Second, since nearly 80% of the world’s water resources are used to support agriculture, continued improvements in agricultural and irrigation conservation and efficiency should be an important focus for research, development, investment and cooperation. In the Middle East, some countries, notably Israel, are pioneers of efficiency, while others are less advanced. Much of the technology is in place. It just needs to be disseminated and embraced across the entire region.

Third, our report and others that have preceded it clearly demonstrate that satellite technology has advanced to the point where a reliable assessment of regional hydrology can be produced with little access to observations on the ground. Our 2009 study of groundwater depletion in India is yet another example of current capabilities. My point is that data denial policies amongst nations will ultimately be rendered obsolete. It will be far better to share key measurements now, to enhance and fully utilize the satellite picture for mutually beneficial water management in the long term.

Killer robots a danger to mankind, warns human rights group

A HUMAN rights group is launching a global campaign to warn of the imminent danger of "killer robots".

They say the machines -- like Arnold Schwarzenegger's character in Terminator - "would be able to select and engage targets without human intervention".

Now Human Rights Watch wants to highlight the danger of killing machines and wants a ban before they become a reality.

The group says robot warfare is the next step up from unmanned drones, and will be available within the decade.

But HRW, a New York based NGO which spends millions each year raising awareness of human rights, says that the public at large are not aware of the danger.

To this end, it is launching the "Stop The Killer Robot" campaign at the House of Commons. Supporters include academics and Nobel peace prize laureates.

It says: “Fully autonomous weapons do not exist yet, but they are being developed by several countries and precursors to fully autonomous weapons have already been deployed by high-tech militaries.

“Killer robots are weapons with full autonomy would be able to choose and fire on targets without any human intervention.

“The aims of the conference are: 1) To increase civil society awareness and understanding of the challenges posed by fully autonomous weapons (killer robots); and 2) To encourage action by civil society to campaign for a ban on their development, production, and use.”

Dr Noel Sharkey, a robotics expert at Sheffield University, warns that automated weapons are unregulated and pay little heed to moral implications or international law.

He said: “These things are not science fiction; they are well into development.” More

 

 

In Mali, al-Qaida kept Xeroxed tipsheet with 22 suggestions on how to avoid drones

TIMBUKTU, Mali — One of the last things the bearded fighters did before leaving this city was to drive to the market where traders lay their carpets out in the sand.

The al-Qaida extremists bypassed the brightly colored, high-end synthetic floor coverings and stopped their pickup truck in front of a man selling more modest mats woven from desert grass, priced at $1.40 apiece. There they bought two bales of 25 mats each, and asked him to bundle them on top of the car, along with a stack of sticks.

“It’s the first time someone has bought such a large amount,” said the mat seller, Leitny Cisse al-Djoumat. “They didn’t explain why they wanted so many.”

Military officials can tell why: The fighters are stretching the mats across the tops of their cars on poles to form natural carports, so that drones cannot detect them from the air.

The instruction to camouflage cars is one of 22 tips on how to avoid drones, listed on a document left behind by the Islamic extremists as they fled northern Mali from a French military intervention last month. A Xeroxed copy of the document, which was first published on a jihadist forum two years ago, was found by The Associated Press in a manila envelope on the floor of a building here occupied by al-Qaida of the Islamic Maghreb.

The tipsheet reflects how al-Qaida’s chapter in North Africa anticipated a military intervention that would make use of drones, as the battleground in the war on terror worldwide is shifting from boots on the ground to unmanned planes in the air. The presence of the document in Mali, first authored by a Yemeni, also shows the coordination between al-Qaida chapters, which security experts have called a source of increasing concern.

“This new document... shows we are no longer dealing with an isolated local problem, but with an enemy which is reaching across continents to share advice,” said Bruce Riedel, a 30-year veteran of the CIA, now the director of the Intelligence Project at the Brookings Institute.

The tips in the document range from the broad (No. 7, hide from being directly or indirectly spotted, especially at night) to the specific (No 18, formation of fake gatherings, for example by using dolls and statues placed outside false ditches to mislead the enemy.) The use of the mats appears to be a West African twist on No. 3, which advises camouflaging the tops of cars and the roofs of buildings, possibly by spreading reflective glass.

While some of the tips are outdated or far-fetched, taken together, they suggest the Islamists in Mali are responding to the threat of drones with sound, common-sense advice that may help them to melt into the desert in between attacks, leaving barely a trace.

“These are not dumb techniques. It shows that they are acting pretty astutely,” said Col. Cedric Leighton, a 26-year-veteran of the United States Air Force, who helped set up the Predator drone program, which later tracked Osama bin Laden in Afghanistan. “What it does is, it buys them a little bit more time — and in this conflict, time is key. And they will use it to move away from an area, from a bombing raid, and do it very quickly.”

The success of some of the tips will depend on the circumstances and the model of drones used, Leighton said. For example, from the air, where perceptions of depth become obfuscated, an imagery sensor would interpret a mat stretched over the top of a car as one lying on the ground, concealing the vehicle.

New models of drones, such as the Harfung used by the French or the MQ-9 “Reaper,” sometimes have infrared sensors that can pick up the heat signature of a car whose engine has just been shut off. However, even an infrared sensor would have trouble detecting a car left under a mat tent overnight, so that its temperature is the same as on the surrounding ground, Leighton said.

Unarmed drones are already being used by the French in Mali to collect intelligence on al-Qaida groups, and U.S. officials have said plans are underway to establish a new drone base in northwestern Africa. The U.S. recently signed a “status of forces agreement” with Niger, one of the nations bordering Mali, suggesting the drone base may be situated there and would be primarily used to gather intelligence to help the French.

The author of the tipsheet found in Timbuktu is Abdallah bin Muhammad, the nom de guerre for a senior commander of al-Qaida in the Arabian Peninsula, the Yemen-based branch of the terror network. The document was first published in Arabic on an extremist website on June 2, 2011, a month after bin Laden’s death, according to Mathieu Guidere, a professor at the University of Toulouse. Guidere runs a database of statements by extremist groups, including al-Qaida in the Islamic Maghreb, and he reviewed and authenticated the document found by the AP.

The tipsheet is still little known, if at all, in English, though it has been republished at least three times in Arabic on other jihadist forums after drone strikes took out U.S.-born cleric Anwar al-Awlaki in Yemen in September 2011 and al-Qaida second-in-command Abu Yahya al-Libi in Pakistan in June 2012. It was most recently issued two weeks ago on another extremist website after plans for the possible U.S. drone base in Niger began surfacing, Guidere said. More

 

'Sand dams' bank water for dry season in semi-arid Kenya

MAKUENI, Kenya (AlertNet) – Barely a month after heavy rains pounded Kenya, many seasonal rivers in the country’s semi-arid east are already drying up, and residents are preparing for the months-long dry season.

But some, like Paul Masila and other members of the Woni Wa Mbee self-help group, are not worried about the looming dry spell. Instead, they are preparing to plant crops or are harvesting fields they planted before the rains.

The group – the name means “progressive vision” in Kamba, the local langage – have revolutionised the region’s fortunes by finding a way to store millions of litres of water under the bed of the Kaiti River, providing the once-parched community with water for domestic use and irrigation throughout the year.

“Drought will never again be a problem, particularly for future generations,” said Titus Mwendo, a 31-year-old farmer in Miambwani, in the Eastern region’s Makueni County.

The Kaiti, like other seasonal rivers in the region, fills with water only during the rainy season, which usually arrives in December.

“The rest of the year is characterised by scorching sun, dry rivers, dusty roads – only those who are fit can survive,” said Masila, a member of Woni Wa Mbee.

But Woni Wa Mbee and other self-help groups in the area, aided by local non-governmental organisations, have found a way to trap and store the Kaiti’s water in its own sandy riverbed, keeping water available for months after the river has disappeared.

“The water reservoirs are called sand dams,” said Kevin Muneene, chief executive officer of the Utooni Development Organisation, one of the supporting NGOs. Over the past two years, the organisation has helped 80 self-help groups construct 1,528 sand dams in arid and semi-arid areas of Kenya’s Rift Valley and Eastern region.

CONSTRUCTION DETAILS

To make a dam, he said, a high concrete barrier is constructed across a seasonal river. When it rains, the water carries sand downstream, depositing it up to the level of the barrier. When the rains finish, water remains trapped in the piled-up sand for up to a kilometre upstream of the dam, depending on the dam’s height.

“A well-constructed sand dam has 60 percent of its volume as sand, while the remaining 40 percent is always water,” said Muneene, an expert in sand dam construction.

In terms of volume, it is estimated that an average sand dam in a relatively wide stream such as the Kaiti River can hold up to 5,000 cubic metres of water, equivalent to 5 million litres. To boost the volume of water stored, several sand dams can be built along one river.

Those numbers suggest that the 1,528 sand dams already built as part of the project will be able to store up to 7.7 billion litres of water, which can be used to irrigate thousands of hectares of land and supply thousands of households for months after the rains stop.

To use the water, community members scoop out sand from the river bed to expose it. It can then be pumped out for irrigation or other uses.

Over 3,000 households are now using water from the dams to grow vegetables, tomatoes, drought-resistant legumes, fruit trees such as grafted mangoes and oranges, and other crops.

“For the first time, we have had water throughout two years. This is not a common phenomenon in this area,” said Florence Munyoki, the treasurer of Woni Wa Mbee and a smallholder farmer in Utaati village. More

The top of the dam is I believe, supposed to be level or just below the the normal river bed. Pictures and drawings that I have seen in other areas in Africa are built in the way I describe. Built in this manner they will not act in a way that may obstruct the run of the river. Editor

China and Russia block UN Security Council climate change action

Russia and China blocked efforts last Friday to have climate change recognised as an international security threat by the UN Security Council (UNSC).

The council met in New York to discuss the potential effects of global warming, but according to Bloomberg the two permanent members objected to it being a ‘formal session’.

Despite the participation of UN Secretary-General Ban Ki-moon this meant the session – planned by Pakistan and the United Kingdom – had few political implications.

China, Russia, India and more than 100 developing countries oppose climate becoming a UNSC issue as the council does not operate under the principles of Common But Differentiated Responsibility, which underpins the UN climate talks.

They are concerned that securitizing the issue would place a greater burden on poorer nations with large greenhouse gas emissions to take action.

Small island states vulnerable to sea level rises have pushed for climate to be discussed at this level for over two decades.

Marshall Islands representative Tony deBrum expressed frustration with Russia and China’s stance, explaining that 35 years on from gaining independence from the USA the very existence of his country is now in question.

“Our roads are inundated every 14 days,” he said. “We have to ration water three times a week. People have emergency kits for water. We can no longer use well water because it’s inundated with salt.”

The meeting – the third in UNSC history – was convened by council President Pakistan and permanent member the United Kingdom, which despite domestic criticism over its low carbon strategy appears to be embarking on a new initiative to inject momentum into global efforts to cut emissions.

The UK’s new climate envoy Rear Admiral Neil Morisetti is pushing for climate change to be framed as a global security concern.

“The UK believes that the impacts of a changing climate pose a significant and emerging threat to a country’s national security and prosperity,” a Foreign Office spokesman told RTCC.

“The UK is engaging with our international partners and through international forums to better manage this risk.”

Risk multiplier

A 2009 report commissioned by the council identified climate change as a ‘threat multiplier’, stressing it would hit food supply lines and affect the territorial integrity of island states.

And in 2011 it discussed whether ‘green helmet’ climate peacekeepers could be required to prevent conflicts caused by resource scarcity.

Addressing the session, leading German scientist Joachim Schellnhuber explained that rises in global temperatures were likely to have catastrophic consequences.

“With unabated greenhouse-gas emissions, humankind would venture into an uncertain future that is much hotter than ever before in its history – so from a scientist’s perspective, climate change is a global risk multiplier,” he said.

The World Bank’s Rachel Kyte told delegates cities must take the lead in developing low carbon infrastructure, in terms of transport, urban planning and managing water resources.

In a statement Oxfam International’s Tim Gore urged the UNSC to debate the issue further, warning the global food system was already under severe stress as a result of droughts across the US, Africa and Asia.

“Droughts or floods can wipe out entire harvests, as we have seen in recent years in Pakistan, in the Horn of Africa and across the Sahel,” he said.

“And when extreme weather hits major world food producers – like last year’s droughts in the US and Russia – world food prices rocket. This presents a major risk to net food importing countries, such as Yemen, which ships in 90% of its wheat.

“The food riots and social unrest seen in the wake of the 2008 food price spikes were not a one-off phenomenon, but a sign of the risks we face through our failure to feed a warming world.” More

 

18 FEBRUARY 2013 Food Security in the Age of “Water Grabbing”

Water grabbing or the large-scale, rapid privatization of water is happening worldwide, affecting global food security because local farmers are losing access to both land and water resources.

Gaining control of water is often a motive behind land grabs, and according to a 2013 report published in the Proceedings of the National Academy of Sciences, up to 57 million hectares of land and 454 billion cubic meters of water are grabbed each year. Africa accounts for 47 percent of global grabbed land while Asia accounts for and 33 percent. Both of these continents are home to some of the world’s hungriest people.

According to Citigroup’s chief economist, Willem Buiter, “Water as an asset class will, in my view, become eventually the single most important physical-commodity based asset class, dwarfing oil, copper, agricultural commodities and precious metals.”Companies such as General Electric, Goldman Sachs, Dow Chemical, Talisman Energy, and Coca-Cola have already acquired many land and water resources and are all members of Aqueduct Alliance, a water mapping project that helps investors identify and assess water risks. While this technology can help companies use water resources responsibly, the Institute for Agriculture and Trade Policy notes that it can also contribute to more water grabbing because companies will have greater knowledge of water resources.

When companies grab land and water resources, local farmers have to find ways to still grow enough food to feed themselves and earn a living. Small-scale farmers in sub-Saharan Africa have recently increased their use of affordable, sustainable irrigation techniques to overcome challenges created by water scarcity, but water grabbing may damage this progress. According to a National Geographic article, “the best opportunity in decades for societal advancement in the region will be squandered” if African governments and foreign investors fail to support local farmers’ initiatives in favor of large-scale water deals that mainly benefit corporations.

Thirsty crops and hungry people: Symposium to examine realities of water security

You may have guzzled a half-liter bottle of water at lunchtime, but your food and clothes drank a lot more. The same half-liter that quenched your thirst also produces only about one square-inch of bread or one square-inch of cotton cloth.

Agriculture is in fact one of the world's most insatiable consumers of water. And yet it's facing growing competition for water from cities, industry, and recreation at a time when demand for food is rising, and water is expected to become increasingly scarce. Take irrigation, for example, says Fred Vocasek, senior lab agronomist with the nation's largest crop consulting firm, Servi-Tech, Inc., in Dodge City, KS.

"Irrigation withdrawals in the United States have stabilized since about 1980, but food consumption trends are following the upward population trend," he says. "In other words, we have an increasingly hungry world with stable, or limited, freshwater supplies for food production. So, how do we keep pace with the widening gap?"

That's the central question behind the symposium, "Green Dreams, Blue Waves, and Shades of Gray: The Reality of Water," being held Sunday, Feb. 17 from 8:30-11:30 am at the American Association for the Advancement of Science (AAAS) meeting in Boston, MA.

The principal answers, say the symposium speakers, lie in three areas: Protecting our limited stores of freshwater in lakes, streams, and the ground (blue water); optimizing the use of water in crop production (green water); and reusing "waste" water (gray water) that has already served some purpose, such as food processing or energy production.

But those answers also raise a host of additional questions, says Vocasek, who co-organized the session with John Sadler of the USDA-Agricultural Research Service. Who gets the water from an aquifer when farmers want it for irrigation, a gas company wants to pump it for fracking, or a city hopes to water a new golf course? How do we convince producers to adopt water-conserving technologies and practices when it's not in their economic interest to do so? Why can't farmers simply irrigate less?

The last question is especially complex because of the issue of "virtual" water—the hidden water in food that went into growing it, Vocasek says. If the United States, for instance, decides to conserve water in the Ogallala Aquifer by growing less corn and importing grain from China instead, it's still consuming the virtual water that grew the Chinese corn. And because Chinese farmers use water much less efficiently than U.S. producers, by "trying to save water here, we may actually be wasting water on a global scale," he says.

To portray the full extent of this complicated issue, "The Reality of Water" will begin with three talks on the three types of water—blue, green, and gray—and how they can be best used to ensure both adequate food and abundant water supplies for future generations. After those speakers "paint the picture," Vocasek says, "the next three panelists will put the frame around that picture. Because there are limitations due to economics, there are limitations due to legal and ownership issues. And there are limitations due to day-to-day operations."

For example, restricting water use in certain situations or regions can be a useful approach. But government agencies often can't require landowners to cut consumption, because water rights—the right to divert water for specific purposes—are property rights in the United States. Reusing gray water to irrigate crops can also be tricky, because wastewater often carries salts or other contaminants that can damage the soil over time.

Yet another constraint is the large size of the average farm today, which often makes it unattractive for farmers to implement practices, such as cover crops and multi-year crop rotations, that help store water in the soil but take extra time and labor. "You can have a lot of plans," Vocasek says, "but there are practicalities that we deal with, as well."

This is why the symposium includes not only the perspectives of researchers and professors, but also crop consultants and professional agronomists who are "toe-to-toe" with the farmer, Vocasek adds.

"The theory, the research, the data are important, but you've got to have someone to help put it all together, because it can't be done from a university or federal office," he says. "It's got to be done right there on the tractor seat." More
