“Doha has just three days’ supply”: are water shortages the biggest threat to the Middle East?

Karim Elgendy in City Metric: Those who visit the Middle East and North Africa from more temperate climates are often struck with how hot and dry the region is, and how scarce its rainfall. Some wonder why cities became established here, and how they continue to exist despite the lack of renewable freshwater.

These concerns are not entirely groundless. Yet these cities’ existence is not in any way miraculous: it’s merely an example of how one can strike an unsustainable balance between growth and limited resources.

The cities in this region may appear unusual today, but like most around the world, most of them grew out of settlements that had access to enough water to sustain life. This is not to say the region’s cities only grew around water sources: have other favourable geographical characteristics, too.

Many of the region’s cities benefited – still benefit – from proximity to a water body that moderates their temperature. Quite a few benefited from a geography that allows natural ports: these include Alexandria, Jeddah, Aden, Haifa, Acre, Byblos, Casablanca,Tunis, Muscat, and Manama. Others – Doha, Dubai, Kuwait – began life as small pearling ports. The region’s cities are where they are because of water, not despite the lack of it.

Some regional cities benefited from proximity to land trade routes (Aleppo, Marrakesh, Sana’a); others grew near large navigable rivers (Cairo, Baghdad, Basrah). In some cases, cities grew in locations where the climate was more temperate due to altitude (Amman, Aleppo, Sana’a, Taif). In at least two cases – Jerusalem and Mecca – it was spiritual significance that drove city growth.

One factor remains constant in the development of all these cities, though: none of them would have been possible without access to fresh water, be that ground water, surface water (rivers), or direct rainfall. The region’s cities are where they are because of water, not despite the lack of it....

Travel chaos as heavy snow hits Turkey

Terra Daily via AFP: Heavy snowfall descended on large parts of Turkey on Tuesday, snarling road and air traffic and leading to closures of schools, reports said.

In the northern province of Karabuk, a school bus went off the road and turned over on to its side in slick conditions caused by snow, leaving a student dead and 18 others injured, the Dogan news agency reported.

The snowfall also seriously disrupted road traffic across Turkey and caused trouble with the electricity network causing some power cuts, particularly in the northern parts of the country.

Turkey's national flag-carrier Turkish Airlines cancelled 44 international and domestic flights in and out of Istanbul and some other cities including the capital Ankara.

In mega-city Istanbul, the authorities appeared to take every precaution including closing down schools. But the snow has so far failed to appear in the city in the quantities predicted. Some ferries across the Bosphorus have been cancelled....

Shift in Arabian Sea plankton may threaten fisheries

A press release from the Lamont-Doherty Earth Observatory (part of the Earth Institute at Columbia University): A growing “dead zone” in the middle of the Arabian Sea has allowed plankton uniquely suited to low- oxygen water to take over the base of the food chain. Their rise to dominance over the last decade could be disastrous for the predator fish that sustain 120 million people living on the sea’s edge.

Scientists at Columbia University’s Lamont-Doherty Earth Observatory and their colleagues are the first to document the rapid rise of green Noctiluca scintillans, an unusual dinoflagellate that eats other plankton and draws energy from the sun via microscopic algae living within its cells. Noctiluca’s thick blooms color the Arabian Sea an emerald green each winter, from the shores of Oman on the west, to India and Pakistan on the east.

In a study published this week in Nature Communications, the researchers show how the millions of green algae living within Noctiluca’s cells allow it to exploit an oxygen-starved dead zone the size of Texas. They hypothesize that a tide of nutrient-rich sewage flowing from booming cities on the Arabian Sea is expanding the dead zone and feeding Noctiluca’s growth.
           
“These blooms are massive, appear year after year, and could be devastating to the Arabian Sea ecosystem over the long-term,” said the study’s lead author, Helga do Rosario Gomes, a biogeochemist at Lamont-Doherty....

New water balance calculation for the Dead Sea

A press release from the Helmholtz Centre for Environmental Research: The drinking water resources on the eastern, Jordanian side of the Dead Sea could decline severe as a result of climate change than those on the western, Israeli and Palestinian side. This is the conclusion reached by an international team of researchers that calculated the water flows around the Dead Sea. The natural replenishment rate of groundwater will reduce dramatically in the future if precipitation lowers as predicted, say the scientists, writing in the journal Science of the Total Environment. Even now, the available groundwater resources in the region are not sufficient to meet the growing water requirements of the population and agriculture. If the situation worsens, it could therefore have serious social, economic and ecological consequences for the region.

A reliable inventory of existing water resources around the Dead Sea, on the border between Israel, Palestine and Jordan, forms the basis for sustainable water management. The lowest lake on earth is not only one of the biggest tourist attractions in the Middle East; more than four million people rely on the groundwater resources in its catchment basin. For a long time, the complex hydrology of this region presented major unknown factors in the local water balance equation. To some extent it still does. Thanks to improved computer simulations, the researchers were able to
work out – on an international scale for the first time – how much water actually infiltrates from rainfall and replenishes the groundwater reservoir: around 281 million cubic metres per year. This means that we now also know what the maximum withdrawal limit should be if this resource is to be managed sustainably.

... Using the models, the scientists were able, for the first time, to make predictions about possible future changes in the groundwater resources that are so vital for this region: the western (Israeli–Palestinian) side of the lake receives almost twice as much rainfall as the eastern (Jordanian) side. As a result, groundwater replenishment rates are currently around 50 per cent higher on the western side. Climate scenarios predict a decrease in annual rainfall of around 20 per cent. However, the water that currently ends up underground and replenishes these important groundwater resources would be halved. The decrease on the western Israeli–Palestinian side is expected to be around 45 per cent, whereas the water available for the Jordanian (eastern) side would fall by nearly 55 per cent. The social and economic situation could therefore worsen, in Jordan in particular.

Saving and reusing water could therefore be a solution, and the UFZ researchers are developing this concept further with colleagues from Israel, Palestine and Jordan. For instance, the SMART project researched ways of stabilising water supply in the Middle East. The UFZ developed new concepts for decentralised wastewater treatment and made a significant contribution to the water master plan of Jordan, one of the world’s most arid countries. Great importance was attached to adapting the wastewater treatment concept to local conditions, and to collaborating with local scientists and authorities. A special implementation office was set up in Jordan’s Ministry of Water in Amman....

Recurrent floods hit desert cities

Berta Acero at the UN Office for Disaster Risk Reduction: Recurrent flooding is becoming more of a threat in the Arab region, a part of the world usually associated with drought and desertification.  At least seven people were killed, schools were forced to close and vehicles were swept away in the latest flash flooding the Saudi Arabian province of Hail.

The Head of the United Nations Office for Disaster Risk Reduction (UNISDR) in the Arab States Region, Mr. Amjad Abbashar, said urban flooding is a growing challenge in the region as well as globally.  “It is becoming more dangerous and costly because of the increasing population exposed within urban settlements. It is very important that governments manage flood risk today for a safer future through better urban management and resilient infrastructures,” Mr. Abbashar said.

“There is an urgent need to move from relief operations to preparedness and risk reduction and mitigation measures. Flood risk is a reality in the Arab region and it is very important that governments invest in flood prevention measures and an adequate land use planning.”

Flash flooding triggered by heavy downpours has claimed dozens of lives in recent years in the region with Saudi Arabia and Jordan as well as Egypt among the worst affected. The international disaster database EM-DAT recorded at least 300 flooding events between 1981 and 2011 in the region.

Major floods have been hitting Saudi Arabia recurrently since 2009, when almost twice the yearly average of rain (90mm) fell in four hours. More than 100 people were killed and economic losses were estimated at US$270 million in and around of Jeddah....

Water in the Arab world: From droughts to flood, building resilience against extremes

A press release from the World Bank: The Middle East and North Africa (MENA) is the most water scarce region in the world, and its water stress is likely to worsen. In 1950, per capita renewable water resources were four times greater than they are today. By 2050, there are indications indicate that natural water resources in MENA will drop even further, to 11 times less than the global average.

Droughts hit the region with punishing regularity, bringing significant water shortages, economic losses, and adverse social consequences. Between 2008 and 2011, drought in Djibouti caused a yearly economic contraction of approximately 3.9 percent of GDP. Droughts are the third most prevalent hazard in MENA after earthquakes, but despite the alarming levels of water scarcity,  the opposite, floods,  also pose significant danger  in MENA too.

The 2008 floods in Yemen caused damages totaling US$1.6 billion, or six percent of the country’s gross domestic product (GDP). The 2009 floods in Jeddah, Saudi Arabia, brought losses of US$1.4 billion. The 2004 floods in Djibouti led to 230 deaths, US$ 11.1 million in losses, and affected 100,000 people.   Nine years later in 2013, slightly less flooding in Djibouti resulted in fewer victims, though 13 people still died, and there was a far shorter disruption of citizens’ livelihoods.

The difference was the emphasis the country placed in learning how to manage the risks caused by water scarcity and floods, and investing in protective infrastructure. Intense, unusual rains do not have to mean disastrous flooding. Neither does a drought have to become a source of malnourishment....

Conservation cooperation a ‘matter of survival’ for Arabs

Ola Al-Ghazawy in SciDev.net: The Arab region’s best chance of facing the challenges of food insecurity, water scarcity and natural disasters lies in collaborating on environmental preservation, a study says. The study, published in The Lancet (20 January), argues that current academic discussions about health, population and development in the Arab region fail to convey the true level of urgency.

Rather than speaking about security — as is common in much development parlance — the report argues that the Arab world is facing threats great enough to call into question its survival, and calls for “using survival as an analytical concept in studying the dynamics driving the threats”.

Muna Abdel Aziz, a Sudanese consultant in public health medicine based at the Warrington Borough Council, United Kingdom, tells SciDev.Net that “the concept of survival indicates urgency whereas security does not necessarily convey this”.

Ecological sustainability is a key issue because population-environment-development dynamics have an interactive relationship with health, the report says. For example, environmental factors such as droughts can force urbanisation, and the city slums formed as a result can become a breeding ground for disease.

The paper adds that sufficient investment in disaster preparedness is beyond any single nation’s capacity, making collaboration essential. Abbas El-Zein, lead author of the paper and an associate professor at the University of Sydney, Australia, tells SciDev.Net: “We are arguing that collaboration around ecological sustainability offers the best chance of success in dealing with issues such as water scarcity, food insecurity and emergency preparedness”....

Mauritania fertile ground for Arab donors

IRIN: Drought-prone, chronically hungry Mauritania, with the help of the UN, is reaching out to Arab donors, encouraging them to reach beyond their customary role in development and engage in humanitarian response.

Traditional humanitarian donors are largely members of the Organisation for Economic Co-operation and Development (OECD) Development Assistance Committee (DAC). But non-traditional, non-DAC donors’ contributions to humanitarian financing have been increasing in recent years. And with many Western donors cutting budgets amid fears of another recession, the Gulf region has gained influence in aid, especially in countries with large Muslim populations.

In early February, a group of Arab donors visited the food-insecure regions of Brakna and Gorgol, a trip organized by the UN Office for the Coordination of Humanitarian Affairs (OCHA). Gogol and Brakna are severely food insecure. According to the most recent study, from December 2011, acute malnutrition rates surpassed the World Health Organization’s emergency threshold, at 11.7 percent in Gorgol and 12.5 percent in Brakna.

The World Food Programme (WFP), with its partner NGO Au Secours, is targeting 7,000 households across the region with cash transfers of 20,000 ouguiyas per month. It has 120 households on its books in Guosse Village in Brakna.

Chief of Guosse, Sidi Brahim Ould Samba, told IRIN his village, “like so many others, lacks everything… access to water, education and health." Even with ongoing help from the government, WFP, NGOs and other donors, it is never enough to move them much beyond survival, he said...

Despite rains, Dead Sea water levels falls again in December

Space Daily via UPI: Despite rainstorms that have soaked fields and filled reservoirs in Israel during December, the Dead Sea's water level still dropped, water researchers said.

Eli Raz, a researcher at the Dead Sea and Arava Science Center in Ketura said the Dead Sea fell to 427.82 meters (1,403 feet) below sea level in early January, 3 centimeters (slightly more than an inch) lower than the level measured the previous month, the Jerusalem Post reported Wednesday.

In comparison, Lake Kinneret saw an increase of 11 centimeters (slightly more than 4 inches) during the same period. The additional drop in the Dead Sea's water level brought the basin to 0.93 meters (3 feet) below its level one year ago, Hydrological Services data indicated.

The slow in the sea's water-level decrease last month was due in part to rainy conditions and lower temperatures that slowed the evaporation rate, Raz said....

Besieged Gaza Strip battered by historic storm

International Solidarity Movement: Gaza’s bad weather has disrupted access lines and flooded whole areas. Thousands of families have been evacuated. Numerous injuries and two deaths have been reported. The Zionist siege and occupation contribute to aggravating the situation for tens of thousands of people.

The main route of access between the north and south of the Gaza Strip, called Saladin Street has been flooded, making travel very difficuly. A microbus running from Gaza to Rafah must be able to avoid deep pools of water by going from one lane to another, slowly and laboriously climbing over the hedge that separates them. Some cars are blocked because the water is high enough to disable their engines. Carts are pulled by donkeys, who walk with their feet in the water.

...In the Jabalia refugee camp, which lies at a low point in the north of Gaza, a young man on the street reported that one man had died from the fatal mixture of broken electricity wires and water in the streets. Boys said that last year, three people and one horse were killed the same way: an electrical wire broke and fell into knee-high sewage water, which the wastewater plant and pumps couldn’t move out of city.

Yusuf Khela, manager of the Jabalia municipality, says that two projects have been underway. One project would pump water directly to the to the wastewater plant further north without passing the sewage treatment plant in Jabalia. To manage this, it would be necessary to pump 3000qm3/h, but because of the fuel shortage, it is often difficult to manage these. The municipality installed two pumps in case one runs out of fuel, to guarantee at least some pumping of water.

Even if there is fuel, it will be expensive, costing 7 NIS per liter. To afford these, the government is even cutting employees’ salaries in order to fuel the pumps. If they stop working, the rain, salt and sewage water mixing together, particularly during the heaviest rain in decades, would first flood all of Jabalia camp....

Winter storm pummels Mideast, adding to refugee misery

Terra Daily via AFP: A bruising winter storm brought severe weather to the Middle East Thursday, forcing the closure of roads and schools and blanketing already miserable Syrian refugee camps with snow.

The nearly three-year-old conflict in Syria has killed an estimated 126,000 people and displaced millions, including more than two million who have fled across the borders and thousands who are living in makeshift camps.

Footage posted online by activists showed war-battered areas of Syria shrouded in snow, and at least two children have died from the cold, according to a spokesman for the opposition National Coalition.

Bad weather also delayed the first-ever international UN airlift, set to leave the Kurdish region of northern Iraq for Qamishli in northeastern Syria. "When it will start is difficult to say -- I think the authorities in Qamishli are going to check conditions at the airfield on Friday," UN refugee agency (UNHCR) regional spokesman Peter Kessler told AFP....

Arab water crisis to affect human development: UNDP report

Asharq Al-Awsat: The Arab world is facing an escalating water crisis that demands quick answers in order to avoid major humanitarian consequences, a United Nations Development Program (UNDP) report warned this week.

The report, entitled Water Governance in the Arab Region: Managing Scarcity and Securing the Future, revealed that out of a total of 22 countries, 15 regional states fall into the “water poor” category, while the situation in seven other states is described as “deteriorating.”

The Middle East and North Africa accounts for 10 percent of the world’s landmass and is home to 5 percent of the world’s population, but has less than one percent of global water resources. An average Arab citizen has eight times less access to renewable water than citizens of other parts of the world, the report said.

“Urbanization and population growth are straining already scarce resources. The population of Arab countries, estimated at 360 million, is expected to reach around 634 million by 2050,” the report warned. “The gap between water supply and demand, estimated at more than 43 cubic kilometers a year in 2009, is expected to reach 127 cubic kilometers a year by 2020–2050,” the report added.

“Water challenges can and must be addressed if the Arab region is to achieve the Millennium Development Goals, attain shared prosperity, and reach a future of sustainable human development. Addressing water challenges now can also help strengthen resilience by managing the risk of potential crises that could result from inaction: such as unplanned migration, economic collapse or regional conflict,” Sima Bahous, the assistant administrator of the UNDP, said in the report’s foreward.

“Resolving the crisis will require enduring progress towards political, social, economic and administrative systems that shape the use, development and management of water resources and water delivery in a more effective, strategic, sustainable and equitable direction,” she added....

Let’s follow Aqaba’s lead on urbanization and disaster risk reduction

Jo Scheuer at the UNDP: For the first time in history, a majority of the global population is urban, and this number is expected to rise. This isn’t necessarily bad — great cities can offer many benefits, especially when urban planning is prioritized. But cities present challenges when urban growth is fast, unplanned and unmanaged. These challenges include high population density, unregulated and unsafe construction methods, environmental degradation, and inadequate water and drainage systems. Lack of planning can create weaknesses, exposing dense populations to worse impacts from disasters associated to natural events.

...The Aqaba Declaration notes that more than 56 percent of the Arab population lives in urban areas. In an urbanizing region, ensuring that cities are more resilient to natural hazards must be a priority. UNDP recommends measures that can be undertaken to address cities’ weaknesses, from developing and enforcing appropriate construction codes to clarifying roles and responsibilities of key officials in the event of a disaster. The key message here is that cities must be engaged, aware, proactive and prepared.

Of course, cities by nature are dynamic and evolving. City administrations attest to the difficulty of fixing entrenched problems that are the result of decades of neglect. But it is possible to stop the pattern and build resilient cities.

Through the Aqaba Declaration, cities in the Arab region have committed themselves to setting up  local units for disaster risk reduction; conducting risk assessments; training volunteers; and establishing early warning systems. We welcome these moves and will support each of these initiatives through our regional and country-level teams.

Integrating risk reduction into development in Aqaba has been a priority for UNDP for many years, and it was through a seismic risk assessment carried out in cooperation with the Swiss Agency for Development and Cooperation that we helped create the Aqaba Disaster Risk Management Unit. We were pleased then when Aqaba was recognized as the first Model City for DRR in the Arab Region by UNISDR in their resilient cities campaign....

Environmental protests of the Middle East show eco awareness in Arab world

Moshe Terdiman in Green Prophet: During the last six years, the words energy security, water security, and food security could be found a lot in the Arab media. Since most of the Arab media is controlled by the Arab regimes, the appearance of these items shows that the environmental awareness of the Arab regimes has been on the rise.

Indeed, as a result of climate change and global warming the Middle East has been facing five major environmental security challenges: water security, food security, energy security, desertification, and land degradation.

These issues have been further aggravated by other socio-economic processes, which characterize the Middle East and include: the huge population growth, the rapid urbanization process and the development of mega-cities on the expense of rural areas.

The urban infrastructures, such as sewage and waste disposal, which have been inadequate anyway and are in dire need for modernization, could not stand the ever-growing human pressure and in a few cities, some of them have totally collapsed.

Moreover, the natural resources, such as water and food, which were just sufficient for the cities’ residents, have been stressed to the limit due to the huge population density within the cities. In addition, green spaces within the cities have given place to gray buildings which have been built whenever possible in order to supply the lodging needs of the incessant stream of new immigrants and local citizens....

Developing world bucks decline in green energy funding

Siobhan Chan in SciDev.net: Spending on renewable energy is undergoing a geographic shift, with developing countries investing more last year despite an overall 12 per cent drop in global spending since 2011, according to two reports published this week (12 June).  The reports found that developing countries invested a total of US$112 billion in renewable energy in 2012, up 19 per cent from 2011.

Just under four per cent of the US$244 billion invested globally went on research and development, rising — albeit only slightly — for an eighth consecutive year. At US$9.6 billion in 2012, global R&D funding has almost doubled since 2004.

'Global Trends in Renewable Energy Investment 2013', by the Frankfurt School-UNEP Collaborating Centre for Climate & Sustainable Energy Finance and information service Bloomberg New Energy Finance, was published alongside 'Renewables 2013: Global Status Report' by REN21, a global renewable energy policy network.

Two-thirds of the 138 countries with renewable energy policies and targets were in the developing world, the Global Trends report found.  Of the developing countries, China continued to dominate the sector, increasing its investment by 22 per cent to US$67 billion. Latin American countries such as Chile and Mexico also increased their investment in the sector.

However, countries in the Middle East and Africa had the greatest growth, increasing spending by 228 per cent to US$12 billion....

Holy land underwater -- a Carbon Based original

    For Easter, the TV schedule teemed with biblical epics (although no Life of Brian -- how odd). The procession included one of the most intelligent and thoughtful examples of the genre -- The Greatest Story Ever Told, directed by George Stevens, with Max von Sydow as Jesus, his hair dyed black. I'd seen it before, and been impressed with its virtues and willing to forgive its flaws. 

    Sure, the Hollywood piety and celestial choruses are grating. Too many of these middle eastern Jews are blond and speak with plummy British accents.  The pace stretches out much too long, especially for us nonbelievers.  Von Sydow struggles bravely to breathe some life into his Gospel-only solemnities. Everybody laughs at John Wayne's line reading as the centurion at the foot of the cross. 

    But many of the performances are superb.  Donald Pleasance portrays Satan as an ineffectual geezer who doesn't have much heart for tempting Jesus, but turns powerful and malevolent when inciting a crowd or steering Jesus to his fate.  Claude Rains does a memorably creepy rendition of Herod doddering on his throne as he orders the death of children.  Charlton Heston devours his role as John the Baptist, and was rightly proud of it.

    But what interests me most are the locations, beautifully shot by Loyal Griggs and William C. Mellor, in Southern Utah near the Glen Canyon Dam in Page, Arizona.  The message board on the film at the Internet Movie Data Base contains several sniffs that the Utah desert is much dryer than the ancient Palestine, which is certainly true, but irrelevant. These desert vistas are otherworldly, some of them of a scale and significance that you might wonder why you haven't seen them before. 

    The reason is, many of them no longer exist. The locations vanished not because of climate change, but as a result of human decisions. Weeks before the filming of the Greatest Story in March of 1963, the gates of the Glen Canyon dam closed, trapping the river.   Many of the locations would soon vanish under Lake Powell.

    A major environmental controversy swirled around that dam. David Brower, head of the Sierra Club, battled the Bureau of Reclamation's plans to contain the Colorado River. The Club argued that the dam would destroy a unique wilderness, and set ominous precedent for plundering America's protected lands.

    In the mid-1950s, the Bureau of Reclamation agreed to forego two other dams, but only if they could proceed unopposed with dams at Flaming Gorge and Glen Canyon. The Sierra Club agreed. Congress authorized the Colorado River Storage Project in April 1956, and groundbreaking for the Glen Canyon followed quickly. 

    At first, many celebrated this outcome a major victory for the American environmentalists -- after all, they'd stopped two dams. But in a few months Brower regretted the Sierra Club's compromise.  With the dam under construction, he traveled down the Colorado River and was shocked by the beauty and grandeur of the landscape he had consigned to submersion.  Brower later wrote, "Glen Canyon died, and I was partly responsible for its needless death. ... Neither you nor I, nor anyone else, knew it well enough to insist that at all costs it should endure. When we began to find out it was too late."

    In the Sierra Club's magazine in 2000, he reflected, "But as surely as we made a mistake years ago, we can reverse it now. We can drain Lake Powell and let the Colorado River run through the dam that created it, bringing Glen Canyon and the wonder of its side canyons back to life. We can let the river do what it needs to do downstream in the Grand Canyon itself."

    In addition to the loss of a landscape and an ecosystem, the environmentalist objections stressed the inefficient water use the dam made of the Colorado River.  The larger the size of Lake Powell, the greater the volume of water lost to evaporation.  "Draining Lake Powell means more water for the Colorado River states and Mexico, especially Colorado and Utah. The hundreds of millions of dollars now being lost, growing to billions in the future, should be enough to give even Bill Gates pause," Brower said. " ... The sooner we begin, the sooner lost paradises will begin to recover."

    The Glen Canyon Dam still stands, but Brower's counterintuitive strictures against dams are especially relevant for the parched Southwest, where larger reservoirs result in more water loss.  The Southwest needs the water more than ever. 

    But even if we make only correct decisions, the long-range outcome will probably be the same.  We'll need to move people out of the desert.

    I suspect that a number of decisions we make about climate change are going to follow this pattern -- environmentalists will support or oppose a project, based on their knowledge at the time, only to discover something later that makes them change their mind.  Long-range impacts are impossible to gauge, even for high-status glamour projects, such as building dams.  And once we reach that point where we know the consequences, it will probably be too late.  To add to the sting, there won't be a biblical movie being filmed to inadvertently document what we're going to lose.

    In the moment we make our decisions, we never know the ultimate outcome. At the George Stevens version of the last supper, getting exasperated with the gnomic utterances, one of the disciples says, "Speak plainly and speak no proverbs."  Good luck to anyone trying to wangle a straight answer out of Jesus, or out of the future -- we won't know the meaning until much later, when the waters are rising.

Why food riots are likely to become the new normal

Nafeez Mossadeq in the Environment Blog at the Guardian (UK): ... We now know that the fundamental triggers for the Arab spring were unprecedented food price rises. The first sign things were unravelling hit in 2008, when a global rice shortage coincided with dramatic increases in staple food prices, triggering food riots across the middle east, north Africa and south Asia. A month before the fall of the Egyptian and Tunisian regimes, the UN's Food and Agriculture Organisation (FAO) reported record high food prices for dairy, meat, sugar and cereals.

...Whether or not those prices materialise this year, food price volatility is only a symptom of deeper systemic problems – namely, that the global industrial food system is increasingly unsustainable. Last year, the world produced 2,241m tonnes of grain, down 75m tonnes or 3% from the 2011 record harvest.

The key issue, of course, is climate change. Droughts exacerbated by global warming in key food-basket regions have already led to a 10-20% drop in rice yields over the past decade. Last year, four-fifths of the US experienced a heatwave, there were prolonged droughts in Russia and Africa, a lighter monsoon in India and floods in Pakistan – extreme weather events that were likely linked to climate change afflicting the world's major food basket regions.

The US Department of Agriculture predicts a 3-4% food price rise this year – a warning that is seconded in the UK. Make no mistake: on a business-as-usual scenario, this is the new normal. Overall, global grain consumption has exceeded production in eight of the past 13 years. By mid-century, world crop yields could fall as much as 20-40% because of climate change alone....

Environmental concerns reach fever pitch over plan to link Red Sea to Dead Sea

Josie Glausiusz in Nature: An ambitious plan to build a pipeline to carry water from the Red Sea to the shrinking Dead Sea lurched forward this month, after the World Bank held hearings to gather public comments on the proposal. But environmentalists charge that alternative plans to save the Dead Sea would be cheaper, more flexible and would have less impact on the region’s ecosystems.

If the project proceeds, a 180-kilometre buried pipeline will carry up to 2 billion cubic metres (m3) of sea water per year from the Gulf of Aqaba on the Red Sea through Jordanian territory to the Dead Sea.

The Dead Sea is world's lowest inland area. Proposals have been put forward to set up the pipeline so that the downward flow of the water goes through a hydroelectric plant that would in turn power a desalination plant, providing up to 850 million m3 of fresh water per year to the parched region. Brine from the desalination plant would be discharged into the already-saline Dead Sea, replenishing water that is evaporating from the lake at a rate of more than 1 metre per year.

The estimated cost of the project would be at least US$10 billion, of which about $2 billion would be for facilities that would pump the desalinated water from the Dead Sea towards Amman — a distance of 200 kilometres, and a difference in altitude of 1,000 metres....

Thirsty Mideast is exhausting its water supply

Tia Ghose in Live Science: The Middle East has depleted its water reserves at a frightening pace over the last several years, according to a new study. From 2002 to 2009, the region lost enough water from groundwater, soil, snowmelt and reservoirs to fill the entire Dead Sea — about 117 million acre-feet (144 cubic kilometers). The majority of that water loss comes from aggressive pumping of groundwater.

...The team was using satellite data from NASA's Gravity Recovery and Climate Experiment (GRACE) project, which measures the change in mass on the Earth below it. The project's primary goal was to track changes in ice sheets.

"GRACE is like a giant scale in the sky, it responds to gravity changes, the satellites are perturbed and they move around in their orbits due to changes in mass," said study co-author James Famiglietti, a hydrologist at the University of California, Irvine. The twin satellites take advantage of the fact that gravity's tug on a spot is proportional to its mass. And water is by far the heaviest thing that changes on Earth, so gravity changes can reveal how much water has been lost. [6 Weird Facts About Gravity]

Famiglietti and his colleagues found that the Tigris Euphrates Basin, which spans parts of Turkey, Syria, Iran and Iraq, lost an average of 16 million acre-feet (20 cubic kilometers) a year during the period of the study. By analyzing other data that tracked other water levels, such as the amount of snowmelt and reservoir levels in the region, the team concluded that most of the depletion came from pumping groundwater.

A drought during that time period may have depleted reservoirs and snowmelt, causing people to more aggressively pump groundwater, Famiglietti told LiveScience. The findings are even more worrisome, because climate change is projected to reduce rainfall in the region, causing even more water troubles, he said....

Winter storm brings devastation to Syria and neighbors

Erika Solomon and Oliver Holmes in Reuters: The worst winter storm in two decades has hit the eastern Mediterranean this week, bringing destruction and death to Syria and its neighbors who are already dealing with a refugee crisis from the country's civil war.

Opposition activists in Syria, where war has forced hundreds of thousands of people from their homes and cut off access to food, fuel and power for cities and towns, say dozens of people have died there in four days of relentless extreme weather.

At least 17 people have also died due to the storm in Lebanon, Jordan, Turkey, Israel and the Palestinian territories. Schools in some areas have been shut for days, refugee camps flooded and villages isolated by closed roads. Meteorological agencies in Israel and Lebanon both called it the worst storm in 20 years.

Snowfall in the Syrian capital Damascus and the northern city of Aleppo did not halt the fighting between rebels and forces loyal to President Bashar al-Assad, which has killed more than 60,000 people in the past 21 months....
