Water Security is National Security

Water resources and how they are managed impact almost all aspects of society and the economy, in particular health, food production and security, domestic water supply and sanitation, energy, industry, and the functioning of ecosystems. Under present climate variability, water stress is already high, particularly in many developing countries, and climate change adds even more urgency for action. Without improved water resources management, the progress towards poverty reduction targets, the Millennium Development Goals, and sustainable development in all its economic, social and environ- mental dimensions, will be jeopardized.

Grabbing at Solutions: Water for the Hungry First

This piece is part of Water Grabbers: A Global Rush on Freshwater, a special National Geographic News series on how grabbing land—and water—from poor people, desperate governments, and future generations threatens global food security, environmental sustainability, and local cultures


A spontaneous, largely under-the-radar blue revolution is gaining steam in sub-Saharan Africa and has the potential to boost food security and incomes for tens of millions of the region’s poorest inhabitants.


Small-scale irrigation techniques with simple buckets, affordable pumps, drip lines, and other equipment are enabling farm families to weather dry seasons, raise yields, diversify their crops, and lift themselves out of poverty.

But unless African governments and foreign interests lend support to these farmer-driven initiatives, rather than undermine them through land and water deals that benefit large-scale, commercial schemes, the best opportunity in decades for societal advancement in the region will be squandered.



Worldwide, as the limits of available water become ever more apparent, the rush is on to acquire more of the precious liquid before there’s none to be had. Government and business interests from China, India, Saudi Arabia, the United States, and other countries that have depleted many of their own water sources are now acquiring access to the land and water of other nations – especially poor ones – to rake in profits and secure food supplies.



The 2008 spike in global food prices unleashed a frenzy of land and water deals that threaten not only the livelihoods of millions but also the geopolitical security of nations.



Nowhere is this more evident than in Africa, especially poor countries south of the Sahara. Business and government interests are targeting Ethiopia, Mali, Sudan, and other underdeveloped nations to capitalize on their “underutilized” farmlands and waters.



Although pitched as investments to advance economic development, many of these deals are not only failing to deliver promised benefits, they are destroying the livelihoods of traditional farmers, herders, and fisherfolk.



Today, hunger is endemic in sub-Saharan Africa. The 2012 Global Hunger Index ranks forty-two of the forty-five countries in the region for which data are available at “serious” or “alarming” levels. Nearly one in four children are underweight. More

How will climate change impact on fresh water security?

Fresh water is crucial to human society – not just for drinking, but also for farming, washing and many other activities. It is expected to become increasingly scarce in the future, and this is partly due to climate change.

Understanding the problem of fresh water scarcity begins by considering the distribution of water on the planet. Approximately 98% of our water is salty and only 2% is fresh. Of that 2%, almost 70% is snow and ice, 30% is groundwater, less than 0.5% is surface water (lakes, rivers, etc) and less than 0.05% is in the atmosphere. Climate change has several effects on these proportions on a global scale. The main one is that warming causes polar ice to melt into the sea, which turns fresh water into sea water, although this has little direct effect on water supply.

Another effect of warming is to increase the amount of water that the atmosphere can hold, which in turn can lead to more and heavier rainfall when the air cools. Although more rainfall can add to fresh water resources, heavier rainfall leads to more rapid movement of water from the atmosphere back to the oceans, reducing our ability to store and use it. Warmer air also means that snowfall is replaced by rainfall and evaporation rates tend to increase. Yet another impact of higher temperatures is the melting of inland glaciers. This will increase water supply to rivers and lakes in the short to medium term, but this will cease once these glaciers have melted. In the sub-tropics, climate change is likely to lead to reduced rainfall in what are already dry regions. The overall effect is an intensification of the water cycle that causes more extreme floods and droughts globally.

When planning future water supplies, however, the global picture is less important than the effect of warming on fresh water availability in individual regions and in individual seasons. This is a much more complicated thing to predict than global trends. The IPCC technical report on climate change and water concludes that, despite global increases in rainfall, many dry regions including the Mediterranean and southern Africa will suffer badly from reduced rainfall and increased evaporation. As a result, the IPCC special report on climate change adaptation estimates that around one billion people in dry regions may face increasing water scarcity.

However, the degree to which this will happen cannot be predicted with confidence by current models. In many regions different models cannot even agree on whether the climate will become wetter or drier. For example, a recent study of future flows in the River Thames at Kingston shows a possible 11% increase over the next 80 years relative to the last 60 years. However, under an identical emissions scenario, the same report shows an alternative projection of a 7% decrease in flows.

Especially little is known about future declines in regional groundwater resources because of lack of research on this topic, even though around 50% of global domestic water supply comes from groundwater. Although scientists are making progress in reducing uncertainty about fresh water scarcity, these kinds of unknowns mean that water supply strategies must be adaptable so that they can be effective under different scenarios.

The direct impact of climate change is not the only reason to be concerned about future fresh water scarcity – a fact highlighted by a recent United Nations Environment Programme report. The increasing global population means more demand for agriculture, greater use of water for irrigation and more water pollution. In parallel, rising affluence in some countries means a larger number of people living water-intensive lifestyles, including watering of gardens, cleaning cars and using washing machines and dishwashers. Rapidly developing economies also result in more industry and in many cases this comes without modern technology for water saving and pollution control. Therefore concerns about climate change must be viewed alongside management of pollution and demand for water.

The most common solution to increasing demand, and a way of insuring against possible climate change impacts, is the engineered redistribution of freshwater over space and time: reservoirs to store it, pipelines to transfer it, and desalination to recover freshwater from the oceans. Efforts are also being made to increase water saving, reuse and recycling, and in the UK there is currently major investment into education and water-saving technology by the government and water industry.

DJIBOUTI: Rising food insecurity fuels migration

BALBALA, 27 November 2012 (IRIN) - Successive years of poor rains have eroded the coping mechanisms of pastoralists in Djibouti’s rural regions, even as high food prices and unemployment rates afflict the country’s urban areas. These factors are increasing the vulnerability to food insecurity and spurring migration.

Checking for malnutrition in Balbala
The area of Balbala, about 12km outside of Djibouti City, has become home to families fleeing both harsh conditions in the countryside and dwindling livelihood opportunities in the city.

“What we need most is food”

Awale Farah, 65, migrated with his family of seven from the rural Ali Sabieh area, near the southern town of Dikhil, to Balbala three months ago. Dikhil lies along the border with Ethiopia and has a large number of migrants, complicating access to scarce basic resources there.

Farah says that back in Ali Sabieh, residents are moving closer to the Ali Addeh refugee camp, hoping to obtain some of the assistance meant for the camp’s 16,778 refugees. “I don’t know how they are getting along. What we need most is food,” he said.

At present, about 70,000 people in rural Djibouti are food insecure. More than 60 percent of household food supply is being met by food assistance in the northwest pastoral zone, according to an October-to-March 2013 food security outlook by the Famine Early Warning Systems Network (FEWSNET).

In the southeast pastoral border area, “households are marginally able to meet minimum food needs only through accelerated depletion of livelihood assets and adoption of unsustainable coping strategies such as charcoal sales,” the outlook says.

The areas most affected by hunger include Obock in the north, Dikhil and Balbala. According to 2010 figures, 42.9 percent of the children in Obock showed signs of wasting. In 2006, Djibouti ranked second in the world for prevalence of wasting in children under five, at 21 percent.

But life in Balbala is not easy, either. “The situation here is very hard. Sometimes we get money from family members in town,” Farah said. “In Dikhil, at least we had livestock that would always provide us with food.” Even so, many pastoralists have lost their livestock to the successive droughts.

''Today, I left at 4am to go and look for work and came back home with nothing. There are days when we eat nothing''
To cope, Farah has split up his family - two of his children are staying with relatives in Djibouti City.

Unemployment and high prices

Meanwhile, a lack of jobs is causing city residents to migrate to peri-urban areas such as Balbala.

Abdillahi Djama Abdiguedi’s family moved to Balbala from Gagada, an area closer to the city where rent cost them 5,000 Djibouti francs (about US$28.20) per month.

“Here, we pay nothing,” he said. “Most of the people around here moved from the city.”

Abdiguedi works as a casual labourer every morning, heading to town to search for work at construction sites. “Today, I left at 4am to go and look for work and came back home with nothing. There are days when we eat nothing,” he said. “The children have forgotten what milk is." More

Nile dam project a hydropower hope, but regional sore point

ADDIS ABABA, Ethiopia (AlertNet) – Ethiopia has begun construction of a 6,000 megawatt (MW) hydroelectric dam on the Blue Nile river, a move that has been greeted enthusiastically by many Ethiopians but that is causing concern in the downstream nations of Sudan and Egypt.

The project, which is scheduled to take six and a half years to complete, is being managed by the state-owned power utility company, Ethiopian Electric Power Corporation (EEPCo). The dam is being built about 900 km (560 miles) north-east of the capital, Addis Ababa, and just 40 km (25 miles) from the Sudanese border.

Ethiopia’s government hopes to capitalize on the energy potential of a river that is revered by the Ethiopian population but that until now has not been significantly exploited to feed the country’s growing need for electric power.

Ethiopia is the source of the Blue Nile, and its territory contributes up to 86 percent of the river’s water. The Blue Nile in turn is responsible for more than half of the water in the Nile, the world’s longest river system. The other main source, the White Nile, originates on the Ugandan side of Lake Victoria.

The new project is not the first dam to be constructed on tributaries of the Nile in Ethiopia. Three smaller projects with a combined capacity of about 760 MW have already been completed, and EEPCo is seeking financing for a 278 MW dam on another tributary, the Chemoga-Yeda River. But the planned Grand Renaissance Dam (GRD) dwarfs these projects in scale and cost.

The 6,000 MW dam will be built by Italian construction company Salini Costruttori, which received the construction contract in late 2010, while electromechanical work is being done by a local company, Metal and Engineering Corporation.

Ethiopia has been dubbed “the water tower of east Africa” because of its numerous river and lake systems. The Nile is an emblematic part of the country, immortalized in poems and songs and even on coins and bank notes. But its potential for hydroelectric power has until now gone largely unused.

For many Ethiopians, the new planned dam is not only about lighting their houses and providing power for businesses and to export, but it also holds a symbolic significance, a way of looking forward from memories of famine and conflict.

WORRIED NEIGHBOURS

Despite its popularity among Ethiopia’s population, the dam project has caused consternation in neighbouring Sudan as well as in Egypt, both downstream countries that rely upon the Nile for almost all their water and fear the dam will cause a reduction in water available to them.

The new dam will eventually create a lake containing more than 60 billion cubic metres of water, twice as much as Lake Tana, Ethiopia’s largest body of water.

There are also concerns about the potential environmental impact of the dam, although the scale of opposition has been smaller than that provoked by the Gibe III dam. Gibe III has provoked opposition from groups concerned about the drying up of Kenya’s Turkana Lake, the world’s largest desert lake, which is fed by the Gibe river, and the possible displacement of tribal people in Ethiopia and Kenya.

Gossaye Mengiste, an official of the ministry of water and energy, which oversees EEPCo, said he believed the environmental impact of the project would be minimal and that because the area around the dam is sparsely inhabited, no mass relocation of people would be necessary. More

Water Challenges and Cooperative Response in the Middle East and North Africa

On May 29-31, 2012, the Stimson Center convened a workshop on Water Challenges and Cooperative Response in the Middle East and North Africa as a component of the 2012 US-Islamic World Forum held in Doha, Qatar.

Participants included scientists, academics, policy analysts, and practitioners from several MENA countries, as well as US and European experts. The interdisciplinary working group identified the principal water resource issues facing decision makers and stakeholders in the region, assessed the MENA states’ existing governance capacities and resources to address these emerging pressures, and recommended priority areas and approaches for advancing international and intersectoral cooperation and for identifying and strengthening intellectual and technical resources, tools, lessons, and best practices that could be shared, applied, or adapted across the region.

This report first provides a brief overview of available water resources in the MENA region. It then discusses the salient socio-economic and environmental stresses and trends that will drive and condition water supply and demand over the coming decades. Next, the report sketches prevailing water management approaches that are being developed or might be brought to bear. With this foundation in place, the report then seeks to illuminate the water governance policy options and obstacles confronting the region by examining three case studies: the Tigris-Euphrates basin, the Nile basin, and a side-by-side consideration of water stewardship in Yemen and Oman. Finally, the report concludes by presenting some recommendations suggesting strategies for the MENA countries to build their water management capabilities and bolster collaborative alternatives to managing scarce water resources at both the domestic and regional levels.

UK water resources 'left to weather's mercy'

A new report blames the government for leaving the UK's water resources at the mercy of the weather.

The document from 16 leading environmental organisations says it took the wettest ever summer to avert serious drought.

It warns that another series of dry winters would put Britain back on drought alert.

The government said its draft Water Bill would build resilience into the UK's water infrastructure.

The Blueprint for Water report measures the Government's performance against 10 steps to sustainable water by 2015.

It applauds ministers' commitment to tackle unsustainable abstraction from rivers and wetlands, extend the use of metering at a fair price and develop a catchment-based approach to managing the water environment.

But it says ministers are still failing to produce a long-term, sustainable approach which works with our natural water systems.

The groups want much more use of moors, marshes and plants to store and clean rain water, instead of allowing it to run straight into rivers and thus increase the risk of flooding. This would help tackle droughts as well as floods.

The chair of the Blueprint for Water coalition, Carrie Hume, said: "Lack of action to fix our broken water system is a false economy. We cannot continue to lurch between flooding and drought which is damaging for people, businesses and wildlife."

The Blueprint for Water was launched in November 2010. The Government is scored every two years on its progress. More

Indian monsoons may fail more often due to climate change - study

(Reuters) - The Indian monsoon is likely to fail more often in the next 200 years threatening food supplies, unless governments agree how to limit climate change, a study showed on Tuesday.

The monsoon rains could collapse about every fifth year between 2150 and 2200 with continued global warming, blamed mainly on human burning of fossil fuels, and related shifts in tropical air flows, it said.

“Monsoon failure becomes much more frequent” as temperatures rise, Anders Levermann, a professor of dynamics of the climate system and one of the authors at the Potsdam Institute for Climate Impact Research, told Reuters.

India’s monsoon, which lasts from June to September, is vital for India’s 1.2 billion people to grow crops such as rice, wheat and corn. India last faced a severe widespread drought in 2009 and had to import sugar, pushing global prices to 30-year highs.

The researchers defined monsoon “failure” as a fall in rainfall of between 40 and 70 percent below normal levels. Such a drastic decline has not happened any year in records dating back to 1870 by the India Meteorological Department, they said.

CATASTROPHE

“In the past century the Indian monsoon has been very stable. It is already a catastrophe with 10 percent less rain than the average,” Levermann told Reuters.

The study, in the journal Environmental Research Letters, projected a temperature rise of 4.6 degrees C (8.3 F) over pre-industrial times by 2200. U.N. scenarios indicate a gain of between 1.1 and 6.4 degrees C (2.9-11.5F) by 2100. More

PEC Supports Water Access Projects in Palau, Marshall Islands

26 October 2012: The Pacific Islands Forum Secretariat (PIFS) has reported on recent grants to Palau and Marshall Islands from the Pacific Environment Community (PEC) Fund, which PIFS administers.

Palau will receive US$4 million to establish a solar-powered desalination project, to ensure a regular and reliable supply of safe drinking water to residents in Peleliu, Palau. The project includes the installation of a solar-powered Reverse Osmosis (RO) plant that desalinates groundwater using solar energy, producing fresh water. The solar power generation system will produce approximately 98,820 kilowatt hours (kWh) of energy per year, contributing 0.11% electricity towards Palau’s current power generation. Palau’s Ministry of Public Infrastructure, Industries and Commerce through the Energy Office will be the focal point for the project, and the Bureau of Public Works will operate and maintain the systems upon completion.

A similar project was approved for the Marshall Islands, which will receive US$3,150,105 to establish the Potable Water Solutions for Outer Islands by Photovoltaic (PV) Reverse Osmosis (RO) System Project. This project will assist islands in maintaining water supply while minimizing the effects of long, dry periods of little to no rainfall. Under the project, small portable solar PV powered RO systems will be installed at community elementary schools in each outer atoll, providing 150 to 300 gallons of fresh potable water daily.

The PEC Fund is a commitment by the Government of Japan to provide 6.8 billion Japanese yen (approximately US$66 million) to Forum Island Countries for the establishment of solar and desalination initiatives to address environmental challenges. Islands which have accessed the fund include Cook Islands, the Federated States of Micronesia, Fiji, Kiribati, Nauru, Niue, the Republic of Palau, Samoa, Solomon Islands and Tuvalu.

SIWI Releases Outcomes of World Water Week on Water and Food Security

29 October 2012: The Stockholm International Water Institute (SIWI) has released a report of the overarching conclusions of the 2012 World Water Week, which convened 2500 participants to discuss the theme of water and food security.

The report, titled “Overarching Conclusions World Water Week in Stockholm 2012: Water and Food Security,” includes sections on: prizes and awards; overarching conclusions; convening organizations; 2013 World Water Week; and 2012 World Water Week supporters and sponsors. The report also contains reports on: achieving good water and food governance; human and environmental health; establishing water and food equity; building a water wise economy; and the young professional's vision.

Among key lessons from World Water Week, the report stresses that water and food security are inseparable, and underscores the importance of producing more with less in order to: minimize movement of pollutants; maintain downstream flows; provide habitat to support pollinators and biodiversity; prevent floods; and sequester carbon to help prevent climate change. It stresses investing in small-holder farmers to increase productivity and water efficiency.

The report calls for: closing leaks in the global food supply chain; improving early warning systems to respond to agricultural emergencies; safeguarding ecosystems while expanding agriculture; promoting fair and effective food trade; refining the nexus approach to address water, food and energy; and collaboration.

The 2012 World Water Week took place from 26-31 August 2012, in Stockholm, Sweden. The 2013 World Water Week will take place from 1-6 September 2013 on the theme “Water Cooperation - Building Partnerships.” [SIWI Press Release] [Publication:Overarching Conclusions World Water Week in Stockholm 2012: Water and Food Security]

Water crisis could be solved through planned reuse

The aptly named Black Mountains behind my home have been turned a beautiful shade of green by recent and relatively abundant rainfall. Even a brief rain event in Southern Nevada is welcome, but the last month or so has been exceptional and has me thinking of potential opportunities.

Each time I see water dripping off my roof or running down the gutter, I think of the lessons I've learned from architect and visionary Michael Reynolds and his revolutionary Earthship structures, as well as Brad Lancaster and his excellent series of books, "Harvesting Rainfall for Drylands and Beyond."

For example, Reynolds' homes harvest rainwater, store and filter it on site, then reuse every gallon as many as four times before returning it, relatively clean, to the environment. Lancaster's common-sense ideas about water harvesting are equally beneficial. I like to think that the long-term solution to our water issues, and our quest for sustainability, lie in adoption of concepts like these rather than the business-as-usual, environmentally destructive approach of massive engineering projects (think pipeline) that move us in the opposite direction.

Here's how an Earthship water system works. The roof is used to gather rainwater, which flows through a natural filtration system before being stored in a cistern. A pump and modern filtration system sends potable water to a pressure tank to provide conventional household water. Water is used in a conventional way for bathing, washing, etc. That is beneficial use No. 1. Then the fun begins.

Every Earthship has a built-in biological gray water treatment and containment system, or in layman's terms, an interior, lined, sealed and plumbed planter. They typically run along the south side of the home near south-facing windows that provide plenty of light and warmth. These systems are full of plants that clean the air and water while providing an aesthetically pleasing feature to the home. In certain cases they may even grow food. Beneficial use No. 2.

Next, the cleaned gray water is used for flushing toilets, putting an end to the ridiculous practice of flushing with potable water. Beneficial use No. 3. More

Use 'hydro-diplomacy' to avert future water conflict - experts

BANGKOK (AlertNet) - Population growth, urbanisation, industrialisation and climate change are putting pressure on the world’s river basins, and “hydro-diplomacy” is essential if water-related conflicts are to be avoided, experts said on Wednesday.

Cooperation between countries and between different groups within countries, as well as improved political will and the larger participation of societies could help defuse tensions over water and improve governance of water resources, the experts said at a conference in Chiang Rai in Thailand, a nation that shares the waters of the Mekong River with Myanmar and Laos.

“Water is, let us face it, going to be humanity’s crisis number one,” said Ambassador Gopalkrishna Gandhi, a former governor of West Bengal in India, which shares borders and rivers with Bangladesh.

“With global warming, population spikes and water-extraction intensification, river water and ground water are going to come under unprecedented strain,” he added.

Rapid population growth and increased industrial demand mean water withdrawals have tripled over the last 50 years, according to figures from the United Nations.

U.N. studies project that at least 30 nations will be "water scarce" in 2025, up from 20 in 1990. Eighteen of them are in the Middle East and North Africa but parts of India, China and Pakistan are also expected to face water shortages.

A country is judged to be “water scarce” when each person has access to 1,000 or fewer cubic meters of water a year.

“Allocation and sharing of water resources crosses political, spatial, cultural and economic boundaries,” said Aban Marker Kabraji, Asia regional director for the International Union for Conservation of Nature (IUCN), which organised the conference.

Diverse users, from farmers to industry and urban developers, are all competing for a limited resource, she said.

“Many technical water infrastructure solutions of the past are now seen to be unsustainable, and we need new ways to meet the demands of human growth while ensuring a sustainable future,” Kabraji said.

ENERGY-FOOD-WATER NEXUS

Because water, energy and food needs are increasingly inter-related, increasing transboundary cooperation on water – or the lack of it - will have wide ranging impacts, experts said.

For Torkil Jønch Clausen, the conference’s keynote speaker, it is increasingly clear that water issues must be tackled from a wider perspective and by a wide range of people, not just water experts.

"Water's a human right. We need 50 litres per day for our basic needs. That is not a political problem. No country does not have that,” said Clausen, a senior advisor to the Global Water Partnership and chair of the scientific programme of World Water Week in Stockholm.

“But every day the food we eat takes 50, 60 times that much water to produce,” he said, and “in many cases in the world, the environment has paid the price for our production of food and energy.”

Agriculture is responsible for two-thirds of global water withdrawals, he said. It takes 1,500 litres of water to produce one kilo of cereals and 10 times that to produce a kilo of meat, a significant problem as demand for meat continues to rise, particularly in developing nations such as China.

As the Obama administration pursues its "Asia pivot," Tibet is taking on increased strategic significance due to its importance as a source of water and minerals, the militarization of the Tibetan plateau and the Sino-Indian border, Chinese influence in Nepal, and Beijing's insistence on deference to its control of Tibet as a "core interest." The series of self-immolations by Tibetans over the past year demonstrates that 60 years of Communist Chinese occupation has not succeeded in destroying Tibetans' identity and desire for freedom. This still unfolding unrest and the democratization of the Tibetan government-in-exile make imperative a review of international policies.

Moving forward, what role will Tibet play in the region's peace and security? Do the U.S. and India have the right policies in place for Tibet? What policies is China pursuing in response to recent events and in anticipation of the future? What are the prospects for achieving the autonomy the Dalai Lama seeks? Can Tibetan Buddhism and democracy provide a bridge between Tibetans and Chinese?

Discussing these vital questions will be Brahma Chellaney of the Centre for Policy Research; Michael J. Green of the Center for Strategic and International Studies; Lodi G. Gyari, special envoy of His Holiness the Dalai Lama; and Ambassador Lalit Mansingh, former Indian Foreign Secretary. FPI Director of Democracy and Human Rights Ellen Bork will moderate the discussion.

Old wisdom still provides succour

Several millenniums ago, ancient Tamils understood the importance of water harvesting and had excellent conservation techniques in place.

Veeranam lake
For example, the Veeranam lake that provides drinking water to Chennai, was built by the Cholas during the 11th Century. Originally named as “Veera Narayanan Yeri” after Rajaraja Chola’s title of “Veera Narayanan”, the lake provides succour to parched throats in Chennai even today.

Similar facilities were created in several places by Rajaraja like the “Cholagan-gam”, (now Ponneri) lake in Gangai Konda Cholapuram. Much earlier, about 1,800 years ago, Karikala Chola built the famed “Kallanai” to dam Cauvery, which is still going strong.

As early as the 3rd Century AD, Kancheepuram district was hailed as ‘Yeriyur Nadu’, (lake country) for its extensive network of lakes and ponds. Rain water was harvested by storage facilities like Yeri, Vaavi, Kulam and Kuttam. In the Sangam age Purananuru lyric “Adupor Sezhiya.....Thalladorey,” Kudapulaviyanar asks the Pandiya king to acquire sky-high reputation by setting up lakes. Kooram copper plates say that a canal (Perumbidugu Kal) was dug up to bring water to ‘Parameswara Thadagam’, a lake that was being newly built to provide water to Parameswara Mangalam, a neighbourhood given as grant to Brahmins circa 699 AD during the times of Parameswara Varma I.

Former epigraphist S Ramachandran says the ancient “Kudi Maramatthu” system of cleaning up clogged water channels, desilting lakes, canals and reservoirs could perhaps have only a few parallels elsewhere in history. More

Nile Basin at a Turning Point as Political Changes Roil Balance of Power and Competing Demands Proliferate

In 1979, Egyptian President Anwar Sadat famously said that “the only matter that could take Egypt to war again is water.” Sadat’s message was clear: the Nile is a matter of national security for Egypt.

Indeed, Egypt relies on the Nile for 95 percent of its water. But it is not the only state with an interest in the world’s longest river. There are 11 states in the Nile River basin, which stretches from Africa’s Great Lakes region – Tanzania, Uganda, Kenya, Rwanda, Burundi, and the Democratic Republic of the Congo – to the Ethiopian and Eritrean highlands through South Sudan, Sudan, and Egypt to the Mediterranean Sea.

Each of these 11 countries has a different plan for the river, from Ethiopia’s hydropower aspirations to Egypt’s cotton farming. And competition for Nile water is not limited to the countries of the basin, as states like India and Saudi Arabia have recently turned to large-scale land and agricultural investments in Ethiopia, South Sudan, and other East African countries to help feed their growing populations. Agriculture requires irrigation, and they will be vying for water rights too.

The situation is further complicated by recent political instability. Two long-time giants in the basin are no longer in power: Egyptian President Hosni Mubarak resigned after 30 years in power following protests in 2011, and Ethiopian Prime Minister Meles Zenawi died August 20, after 17 years in office.

The Arab Spring has made it unclear if Egypt is willing or able to enforce its long-held dominance of the region. Further downstream, the Great Lakes region is notoriously prone to conflict; Sudan and South Sudan are still clashing over a number of issues not settled by the 2005 Comprehensive Peace Agreement or the South’s subsequent secession; Ethiopia and Eritrea remain on edge since the formal end of their war in 2000; and Kenya, Burundi, the DRC, and Rwanda have had recent questionable elections and remain volatile.

Despite their differences, the Nile River basin countries have one thing in common: rapid growth, both economically and demographically, which is increasing demand for water across the board and lends urgency to negotiations for a common sharing agreement.

New Challenges to Historic Dominance

At the root of the current dynamic are agreements signed by Egypt with former colonial power Great Britain in 1929, and Sudan in 1959, which gave Egypt the lion’s share of the Nile as well as the power to veto any upstream projects which might threaten its access to water. Egypt claims these treaties give them the legal right to halt construction on projects like the Grand Renaissance Dam, a massive project recently begun in Ethiopia that would provide electricity to Ethiopia and surrounding states but also reduce downstream flow significantly.

"...In every corner of the globe, we are polluting, diverting, pumping, and wasting our limited supply of fresh water at an expediential level as population and technology grows. The rampant overdevelopment of agriculture, housing and industry increase the demands for fresh water well beyond the finite supply, resulting in the desertification of the earth.

Corporate giants force developing countries to privatize their water supply for profit. Wall Street investors target desalination and mass bulk water export schemes. Corrupt governments use water for economic and political gain. Military control of water emerges and a new geo-political map and power structure forms, setting the stage for world water wars.

We follow numerous worldwide examples of people fighting for their basic right to water, from court cases to violent revolutions to U.N. conventions to revised constitutions to local protests at grade schools. As Maude Barlow proclaims, "This is our revolution, this is our war". A line is crossed as water becomes a commodity. Will we survive?..."

Retreat of the Miage Glacier

Miage Glacier (3)Photographer: Piero Armando Summary Author: Piero Armando During summer holidays, I often visit the Miage Glacier in the Italian Alps. The Miage Glacier flows from the south side of Mont Blanc and is one of the longest in the entire massif (about 16 mi or 10 km in length). My first trip to this scenic alpine area was in July 1966. There's been an obvious retreat of the Miage Glacier since then. The left photo shows how the landscape appeared during my initial visit. The right photo was snapped from roughly the same position but some 46 years later. Note that the glacial lake in the foreground of the left photo is now five small shallow lakes -- each with levels at least 30 ft (about 10 m) lower than in 1966. The sharp peak visible in the background is the famousAiguille Noire (12,379 ft or 3,773 m in height). Behind Aiguille Noire is the Peuterey Crest, which leads to the summit of Mont Blanc. Right photo taken on August 22, 2012.Photo details: Canon EOS 30D camera; 17mm focal length; f/11.0 aperture; 1/250 sec. exposure; ISO equivalent 100; sRGB color space; four separate exposures stitched together.

Academy Finds Mixed Climate Impacts on Himalayan Glaciers, Water Supplies

The eroding Rongbuk glacier in the Himalayas, in 1921 and today.
Given all the oversimplified assertions over the years about Himalayan glaciers in a warming global climate, it’s great to see a committee assembled by the National Academy of Sciences weigh in on the question with some data-based findings in a new report, “Himalayan Glaciers: Climate Change, Water Resources, and Water Security.” The bottom line — in sync with other recent analysis — is that the region is seeing a mix of changes, with glaciers growing in some places and shrinking in others and impacts on water supplies mostly inconsequential for decades to come. In most regions, monsoon patterns, population and consumption pressures and dependence on groundwater pumping will remain the dominant source of water-related risks, the report concludes. Read on for an excerpt from the news release and link to the full report, followed by related background:



Himalayan Glaciers Retreating at Accelerated Rate in Some Regions but Not Others; Consequences for Water Supply Remain Unclear, Says New Report

WASHINGTON — Glaciers in the eastern and central regions of the Himalayas appear to be retreating at accelerating rates, similar to those in other areas of the world, while glaciers in the western Himalayas are more stable and could be growing, says a new report from the National Research Council.

The report examines how changes to glaciers in the Hindu Kush-Himalayan region, which covers eight countries across Asia, could affect the area’s river systems, water supplies, and the South Asian population. The mountains in the region form the headwaters of several major river systems — including the Ganges, Mekong, Yangtze, and Yellow rivers — which serve as sources of drinking water and irrigation supplies for roughly 1.5 billion people.

The entire Himalayan climate is changing, but how climate change will impact specific places remains unclear, said the committee that wrote the report. The eastern Himalayas and Tibetan Plateau are warming, and the trend is more pronounced at higher elevations. Models suggest that desert dust and black carbon, a component of soot, could contribute to the rapid atmospheric warming, accelerated snowpack melting, and glacier retreat.

While glacier melt contributes water to the region’s rivers and streams, retreating glaciers over the next several decades are unlikely to cause significant change in water availability at lower elevations, which depend primarily on monsoon precipitation and snowmelt, the committee said. Variations in water supplies in those areas are more likely to come from extensive extraction of groundwater resources, population growth, and shifts in water-use patterns. However, if the current rate of retreat continues, high elevation areas could have altered seasonal and temporal water flow in some river basins. The effects of glacier retreat would become evident during the dry season, particularly in the west where glacial melt is more important to the river systems. Nevertheless, shifts in the location, intensity, and variability of both rain and snow will likely have a greater impact on regional water supplies than glacier retreat will. More

Asia Risks Water Scarcity Amid Coal-Fired Power Embrace

Inner Mongolia’s rivers are feeding China’s coal industry, turning grasslands into desert. In India, thousands of farmers have protested diverting water to coal- fired power plants, some committing suicide.

The struggle to control the world’s water is intensifying around energy supply. China and India alone plan to build $720 billion of coal-burning plants in two decades, more than twice today’s total power capacity in the U.S., International Energy Agency data show. Water will be boiled away in the new steam turbines to make electricity and flush coal residue at utilities from China Shenhua Energy Co. (1088) to India’s Tata Power Co. (TPWR) that are favoring coal over nuclear because it’s cheaper.

With China set to vaporize water equal to what flows over Niagara Falls each year, and India’s industrial water demand growing at twice the pace of agricultural or municipal use,Asia’s most populous nations will have to reconsider energy projects to avoid conflict between cities, farmers and industry.

“You’re going to have a huge issue with the competition between water, energy and food,” said Vineet Mittal, managing director of Welspun Energy Ltd., the utility unit of Leon Black’s Apollo Global Management LLC-backedWelspun Group. “Water is something everyone should be probing every chief executive about,” he said in an interview.

Investors have driven up the 49-member S&P Global Water Index (SPGTAQD) about 96 percent from its low point after the 2008 financial crisis. That beat the 88 percent gain in the period by the 1,625-stock the MSCI World Index, a global benchmark, and trailed the Dow Jones Industrial Average’s 101 percent increase. More

 

Droughts Are Pushing Trees to the Limit

ScienceDaily (Sep. 10, 2012) — Droughts in the Southwest made more severe by warming temperatures are putting plants in stressful growing conditions, a new study has found, identifying an increasingly water-thirsty atmosphere as a key force that sucks moisture from plants, leading to potentially higher stress -- especially in mid and low elevations.

As temperatures rise and droughts become more severe in the Southwest, trees are increasingly up against extremely stressful growing conditions, especially in low to middle elevations, University of Arizona researchers report in a study soon to be published in the Journal of Geophysical Research Biogeosciences.

Lead author Jeremy Weiss, a senior research specialist in the UA department of geosciences, said: "We know the climate in the Southwest is getting warmer, but we wanted to investigate how the higher temperatures might interact with the highly variable precipitation typical of the region."

Weiss' team used a growing season index computed from weather data to examine limits to plant growth during times of drought.

"The approach we took allows us to model and map potential plant responses to droughts under past, present and future conditions across the whole region," explained Julio Betancourt, a senior scientist with the U.S. Geological Survey who co-authored the study along with Jonathan Overpeck, co-director of the UA Institute of the Environment. Betancourt holds adjunct appointments in the UA department of geosciences, the UA School of Geography and Development, the UA School of Natural Resources and the Environment and the UA Laboratory of Tree-Ring Research.

Global food security and "virtual water"

Food production requires adequate soils, climate, and water. Roughly 70 percent of the freshwater appropriated by humans worldwide is used for food production. In the absence of trade, people rely on local freshwater resources to grow food. However, when water limitations constrain food production to the point that there is not enough food for everyone, the trade of food commodities provides a mechanism by which regions can compensate for inadequate local water resources.

The United States' National Intelligence Council and the European Union's Institute for Security Studies estimate PDF that more than one billion people currently live in regions where the demand for water exceeds the local supply. These populations are sustained only via importation of the "virtual water" resources associated with foreign food production.

Global food security depends, in part, on the virtual water PDF trade. The transfer of virtual water from food-producing regions to food-importing regions provides a way to maximize the use of global water resources; allows overpopulated and water-poor countries to meet their food demand; and can ameliorate the effects of drought on local food production. In some schools of thought, the virtual-water trade PDF acts to reduce societal water stress, malnourishment, and water wars.

However, this "globalization of water" has adverse impacts as well. It decouples a population from the production of its food and allows the population to grow at a rate that is unsustainable with respect to local water resources. The decoupling of resources and population can also cause people to care less about the environment they live in. And although the virtual water trade mitigates local water stresses, it also lowers societal resilience to drought by reducing the water options available during a food crisis. Moreover, differences in access to water and trade introduce the potential for large inequalities to arise among nations.

Tracking the flow of virtual water. Detailed population data and trade information for 309 plant and animal food commodities, combined with production estimates of virtual water by crop commodity and country, have made it possible to reconstruct the network of virtual water flows from 1986 through 2008. This network is comprised of links (imports and exports) representing virtual water transfers between countries. The network has changed significantly over the past few decades. The total number of trade connections has increased from 8,213 to 15,789, with the number of active trading nodes (countries) increasing from 205 to 232. Moreover, the total trade in virtual water has increased from roughly 1 trillion cubic meters to about 2.2 trillion cubic meters. This increase has occurred at a rate that exceeded that of population growth, resulting in an overall increase in trade of 150 cubic meters per person per year between 1986 and 2008.

The network of virtual water trade is highly dynamic, with very few permanent links; its structure depends on many factors, including socio-economic and political conditions, demographic dynamics, and water availability. Some of the changes in this network are due to political transformations, such as the dissolution of the former Soviet Union. While both the total virtual water flow and number of trade connections have increased, virtual water trade remains unevenly distributed. In fact, 50 percent of the virtual water flows through only 1.1 percent of the links, and approximately 40 percent of the net virtual water exports come from Brazil, Argentina, and the United States -- countries that account for only 5.7 percent of the global population. Worldwide, 90 percent of virtual water exports are controlled by only 32 percent of the population. The largest net importers of virtual water in 2008 were China and Japan. African nations have low connectivity to the global network, with relatively small amounts of virtual water moving to and from African countries. More
