Freshwater Stores Shrink in Tigris-Euphrates Basin

Scientists using the twin gravity-measuring satellites of the Gravity Recovery and Climate Experiment (GRACE) have found that a large portion of the Middle East lost freshwater reserves rapidly during the past decade. The research team observed the Tigris and Euphrates river basins—including parts of Turkey, Syria, Iraq, and Iran—and found that 117 million acre feet (144 cubic kilometers) of fresh water was lost from 2003 to 2009. That amount is roughly equivalent to the volume of the Dead Sea. About 60 percent of the loss was attributed to the pumping of groundwater from underground reservoirs.

The two natural-color images above were acquired by the Landsat 5 satellite and show the shrinking of the Qadisiyah Reservoir in Iraq between September 7, 2006 and September 15, 2009. The first graph shows the elevation of the water in that reservoir between January 2003 and December 2009. The elevation is a proxy measurement for the total volume of water stored there; labels show the water elevation at the time of the satellite images.

The second graph shows the water storage for the entire study area as measured by GRACE from January 2003 to December 2009. The gray line depicts total water storage in the region—groundwater, surface water bodies, and soil moisture—while the green line depicts changes in surface water. The difference between those two lines reflects the change in water stored in underground aquifers (ground water). The total water storage shows a seasonal fluctuation, but also an overall downward trend, suggesting that groundwater is being pumped and used faster than natural processes can replenish it.

“GRACE data show an alarming rate of decrease in total water storage in the Tigris and Euphrates river basins, which currently have the second fastest rate of groundwater storage loss on Earth, after India,” said Jay Famiglietti, principal investigator of the study. “The rate was especially striking after the 2007 drought. Meanwhile, demand for freshwater continues to rise, and the region does not coordinate its water management because of different interpretations of international laws.”

Obtaining ground-based data in Middle East can be difficult, so data from satellites such as GRACE are essential to providing a global picture of water storage trends. Within any given region on Earth, rising or falling water reserves alter the planet’s mass, influencing the gravity field of the area. By periodically measuring gravity in each region, the GRACE satellites tells us how water storage changes over time. (To learn more about GRACE’s ability to study fresh water on Earth, read The Gravity of Water.)

The researchers calculated that about one-fifth of the water losses in their Tigris-Euphrates study region came from snowpack shrinking and soil drying up, partly in response to a 2007 drought. Loss of surface water from lakes and reservoirs accounted for another fifth of the losses. The majority of the loss—approximately 73 million acre feet (90 cubic kilometers)—was due to reductions in groundwater. “That's enough water to meet the needs of tens of millions to more than a hundred million people in the region each year, depending on regional water-use standards and availability,” Famiglietti said.

South Americans Face Upheaval in Deadly Water Battles

People streamed into the central square in Celendin, a small city in the Peruvian Andes, the morning of July 3, 2012. They were protesting the government’s support for Newmont Mining Corp. (NEM)’s plan to take control of four lakes to make way for a new gold and copper mine. By midday, there were 3,000.

This lake in the Peruvian Andes, once the water supply for farms and villagers, is drying up after Newmont’s Yanacocha mine drained its water

Some hurled rocks at police and brandished clubs. Then assailants shot two officers and an Army soldier in the leg.

Blocks away, construction worker Paulino Garcia left home on foot to buy groceries. As he approached the central square, he encountered chaos. People ran for cover as federal troops fired their weapons,

It was the deadliest clash in 18 months of protests in Peru’s Cajamarca region, where many residents say Newmont’s $5 billion Conga mine will take water their villages and farms need to survive.

“He died in a pool of blood,” says Adelaida Tabaco, Garcia’s widow, 38, sobbing inside her half-built adobe house in Celendin. “The only thing the people want is water for families, but the mining companies want to take it. And soldiers will kill if you get in the way.”

The injured and dead in Celendin, 800 kilometers (500 miles) north of Lima, are victims in a continent-wide conflict that pits South American governments and big, often foreign- based companies against people who stand to lose their homes as water is diverted to industrial uses.

Leaders across the region, elected on promises to fuel economic growth and lift their populations out of poverty, are fast tracking water-use approvals for projects like the Conga mine. Helped by mining and agriculture exports, Brazil’s gross domestic product increased 43 percent from 2002 to 2012, after adjusting for inflation, while Chile’s economy grew 58 percent.

Peru is on target to expand 6 percent in 2013, the fastest pace in South America, driven by investments in gold, silver and copper mines.

South America has more water than any other region on earth, with 29 percent of the world’s reserves, according to the United Nations Food and Agriculture Organization. The rub is that the water isn’t always where the best mineral or agricultural resources are located.

Mines consume huge amounts of water to separate minerals from rock. It takes 28 liters (7.4 gallons) of water to make 0.5 kilogram (1 pound) of copper in Chile. After processing, the water at some mines is so toxic that it can’t be reused. Peru’s biggest mines, such as Conga, are high in the Andes, where there’s almost no rain from May to October.

In Chile, the world’s largest copper producer, vast deposits of copper, gold and silver lie under the Atacama Desert, which is so dry that rainfall has never been recorded in some places. And higher demand means there’s less water to go around.

Growing populations have pushed the amount of usable water per person down by more than one-fifth since 1992 in Brazil, Chile and Peru, according to the UN group.

National leaders in Latin America are weighing short-term economic growth against the public’s future needs for water, and the consequences can be deadly. In Chile, the nation’s drinking supply is threatened by past policies of allotting too much water to companies to spur the economy, Public Works Minister Loreto Silva says.

Water is already running out in places like Copiapo, a city of 158,438 people in the Atacama Desert, 800 kilometers north of Santiago, because of mining and agricultural expansion, she says.

“In some areas of the country, like Copiapo, we have a reduction or an exhaustion of the resource,” Silva says. “If we don’t make decisions today, we’ll be short of water in about a decade. That forces us to take a long-term, strategic view in terms of water.”

Peru faces similar long-term needs because water is in short supply in areas where mines are expanding, says Hugo Jara, head of the country’s National Water Authority. The government needs to build $394 million of reservoirs and canals by 2016 for annual water shortages in the dry season in the Andes, he says.

“The government has declared water its first priority,” Jara says. “These protests helped to spur our attention.”

Governments are making the right decision in providing water to industries that benefit the majority of their populations, even if that means displacing some people, says John Briscoe, a Harvard University professor who specializes in water policy. More

 

 

 

Researcher uncovers hidden facts of Israeli-Palestinian water politics

The Israeli government has been forcing the Palestinian Authority into approving water infrastructure for illegal West Bank settlements for the past 15 years, according to research by a University of Sussex academic.

The research by Senior Lecturer in International Relations Dr Jan Selby is published today (5 February 2013) in the journal Water Alternatives.¹

It presents the first known evidence of the Palestinian Authority lending its official consent to parts of Israel’s settlement expansion programme.

Settlements and related infrastructure are illegal under international law, and are recognised as one of the major obstacles to a two-state solution to the Israeli-Palestinian conflict.

The research is based on minutes of the Joint Water Committee – an Israeli-Palestinian body often upheld as an example of good Israeli-Palestinian relations – and interviews with participants. Dr Selby concludes that:

• Israel has repeatedly made its approval of improvements to Palestinian water supplies conditional upon Palestinian Authority approval of new water facilities for Israeli settlements;
• the Palestinians, who face serious water shortage issues and an underdeveloped supply system, have given this approval in almost every case;
• the arrangement was known about by former Palestinian leader Yasser Arafat and current President Abu Mazen;
• international donors have known that Israel’s approval of donor-funded projects for Palestinians is conditional on Palestinian approval of Israeli settlement infrastructures, but have preferred to remain silent on the issue;
• the Palestinian water crisis in the West Bank has significantly worsened since the creation of the Joint Water Committee.

Dr Selby says: “None of the parties emerge very well from these findings. Israel has been exploiting Palestinian desperation for improved water supplies. The Palestinian Authority has been pressured into consenting to its own colonisation and has not contested Israel’s cynical tactics as forcefully as it might have done.

“And international donors have variously stood by or been complicit in activity which is contrary to international law, and contrary to their own policies on the peace process, and which has helped to undermine the possibility of a two state solution.” More

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.”

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

 

 

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.
