Managing Droughts and Floods in Pakistan

Pakistan has increasingly been suffering from cycles of severe droughts followed by massive floods in the last few years. This recurring pattern of shortage and excess of water gives us a preview of the growing challenge of climate change. This situation calls for a comprehensive water management effort to deal with a potentially existential threat to Pakistan.

Flood-Drought Cycles:

Before the summer floods of 2010, the Indus had turned into a muddy puddle in parts of Sindh. Britain's Financial Times reported at the the time that "angry farmers marched through villages in Sindh demanding access to water. Those who can no longer turn a profit in the fields are increasingly resorting to banditry or migrating to urban shanties".

Earlier, there was a 2009 report by the Woodrow Wilson International Center saying that the melting Himalayan glaciers have exacerbated Pakistan’s shortages. And the World Bank warned that Pakistan could face a “terrifying” 30-40 per cent drop in river flows in 100 year’s time. Now large parts of Sindh are under water for the second year in a row, destroying lives and standing crops.

Growing Water Scarcity:



According to the United Nations' World Water Development Report, the total actual renewable water resources in Pakistan decreased from 2,961 cubic meters per capita in 2000 to 1,420 cubic meters in 2005. A more recent study indicates an available supply of water of little more than 1,000 cubic meters per person, which puts Pakistan in the category of a high stress country. Using data from the Pakistan's federal government's Planning and Development Division, the overall water availability has decreased from 1,299 cubic meters per capita in 1996-97 to 1,101 cubic meters in 2004-05. In view of growing population, urbanization and increased industrialization, the situation is likely to get worse. If the current trends continue, it could go as lows as 550-cubic meters by 2025. Nevertheless, excessive mining of groundwater goes on. Despite a lowering water table, the annual growth rate of electric tubewells has been 6.7% and for diesel tubewells about 7.4%. In addition, increasing pollution and saltwater intrusion threaten the country's water resources. About 36% of the groundwater is classified as highly saline.

So what can Pakistan do to manage these disastrous cycles of floods and droughts?

1. Build Dams and Dykes:



As the flood disaster takes its toll yet again, there are reports of USAID and ADB considering funding the $12 billion Bhasha Dam in Pakistan. The project is located on Indus River, about 200 miles upstream of the existing Tarbela Dam, 100 miles downstream from the Northern Area capital Gilgit in Gilgit-Baltistan region. The dam's reservoir would hold so much water that it could have averted last year's devastating floods. It would also provide enough electricity to end Pakistan's crippling shortages, according to a report in the Guardian newspaper. The massive dam on the Indus river would provide 4,500MW of renewable energy, making up for a shortfall causing up to 12 hours of load shedding on daily basis across Pakistan. The reservoir would be 50 miles long, holding 8.5 MAF (million acre feet) of water.

In addition to large dams, there is also a need to build and maintain dykes and start other flood-control projects in flood-prone areas like Badin and Thatta in Sindh.

2. Conserve Water:

Building Bhasha and several other proposed dams will help in dealing with water scarcity, but the growing population will continue put pressure on the vital resource.



Serious conservation steps need to be taken to improve the efficiency of water use in Pakistani agriculture which claims almost all of the available fresh water resources. A California study recently found that water use efficiency ranged from 60%-85% for surface irrigation to 70%-90% for sprinkler irrigation and 88%-90% for drip irrigation. Potential savings would be even higher if the technology switch were combined with more precise irrigation scheduling and a partial shift from lower-value, water-intensive crops to higher-value, more water-efficient crops. Rather than flood irrigation method currently used in Pakistani agriculture, there is a need to explore the use of drip or spray irrigation to make better use of nation's scarce water resources before it is too late. As a first step toward improving efficiency, Pakistan government launched in 2006 a US $1.3 billion drip irrigation program that could help reduce water waste over the next five years. Early results are encouraging. "We installed a model drip irrigation system here that was used to irrigate cotton and the experiment was highly successful. The cotton yield with drip irrigation ranged 1,520 kg to 1,680 kg per acre compared to 960 kg from the traditional flood irrigation method," according to Wajid Ishaq, a junior scientist at the Nuclear Institute for Agriculture and Biology(NIAB).





Beyond the government-funded experiments, there is a drip irrigation company called Micro Drip which is funded by the Acumen Fund. Micro Drip develops and provides products and services as poverty alleviation solutions to small farmers in Pakistan’s arid regions. It provides a complete drip irrigation system along with agricultural training and after-sales support to enable farmers to extract a higher yield from their land at a much lower cost of input.

So what is holding up Pakistan's progress on water management?

1. Lack of Funds:

Pakistani government revenues continue to be limited by slow economic growth and widespread culture of tax evasion. The biggest culprits are the ruling feudal politicians who oppose any attempt to levy taxes on their farm income. The limited resources the state does have are usually squandered on political patronage doled out to ruling politicians' supporters in the form of capricious grants, huge loans (defaulted with impunity), and plum jobs in bloated government and the money-losing state-owned enterprises. The result of this blatant abuse, waste and fraud is that the budget allocations for vital long-term investments in education, health care and infrastructure development projects are regularly slashed thereby shortchanging the future of the nation.

2. Corruption and Security Concerns:

The NY Times recently reported that "Washington’s fears of Pakistani corruption and incompetence has slowed disbursal of the money". The story reinforces the widely-held view that even after the funding is arranged, the corrupt and incompetent politicians and their hand-picked civilian administrators make any development progress slow and difficult. Such problems are further exacerbated by significant security issues in parts of the country severely plagued by ongoing militancy.

Existential Threat:

The Taliban who get all the coverage do not pose an existential threat to Pakistan. Generations of military families have periodically fought FATA insurgencies. For example, Shuja Nawaz, the author of Crossed Swords says that his grandfather, his uncle and his cousin have all been deployed in Waziristan by the British and later Pakistani governments in the last century and a half. American withdrawal from the region will eventually calm the situation in Waziristan, and the rest of the country.

Climate change and the growing water scarcity are the main long-term existential threats to Pakistan and the region. Water per capita is already down below 1000 cubic meters and declining
What Pakistan needs are major 1960s style investments for a second Green Revolution to avoid the specter of mass starvation and political upheaval it will bring.

KARACHI: Asia's largest reverse osmosis plant, having a capacity to produce two million gallons of water daily, was inaugurated today in Pakistan's drought-ridden Sindh province.

The plant which is billed to produce two million gallons of water per day is expected to reduce the water crisis in Tharparkar district where last year hundreds of children have lost their lives by drinking untreated water.

Former President Asif Ali Zardari inaugurated the plant. Zardari, who is also co-chairman of the Pakistan Peoples Party which heads the province, said his party was committed to provide clean drinking water to the people of the area.

Zardari said Asia's biggest RO plant has been set up at a cost of Rs 300 million while many smaller plants having a capacity of 10,000 gallons per day have also been set up across the region at a cost of around Rs 2.5 million each.

The Sindh government plans to install 300 reverse osmosis (RO) plants in water-starved regions of the province by February.

The number of the ROs already made operational is 150. Irshad Hussain, the chief operating officer of Pak Oasis, the company that has been working in Thar's water sector since 2004, said the government had allocated Rs 5.4 billion allocated to set up RO plants in the region.

He said these plants can be operated through electricity or solar energy and steps were being taken to convert most of the filter plants to solar energy.

"It is solar energy that matters here in this region as it makes operation of ROs cost effective," he added.

Taj Haider, a senior PPP leader who is overlooking the operation in the region said: "For years now people living in the region have had to travel several kilometres to fetch a few buckets of clean water from reservoirs in their area. The situation is going to change now for the people of Tharparkar.

Reverse osmosis plant uses a purification technology that remove salts and other pollutants from water.

MITHI, Pakistan, Feb 2 (Thomson Reuters Foundation) - Worsening drought has led to over 80 percent of water resources in Pakistan's southern Tharparker district becoming unfit for people to drink, a new study says.

That has led to plans by the Sindh provincial government to invest 5.4 billion Pakistani rupees ($53 million) in installing 750 solar-powered reverse osmosis water purification plants across the sprawling desert district, to help get safe drinking water to the region's over 1.5 million people.

All of the facilities are expected to be set up and working by June this year, the government said.

Residents living near a first plant, inaugurated in January in the Misri Shah area of Mithi, the district headquarters of Tharparker, say it is transforming life in the parched region, where vanishing rain and drying groundwater supplies mean most available water is now saline or too high in fluoride.




"It is really hardly less than a miracle for us that we can now drink sweet and clean water, for the first time in my entire life," said 45-year-old Rekha Meghwar of Mithi, as she turns on the water plant's tap to fill her pitcher.

Billed as the 'Asia's largest (by capacity) solar-powered water purification plant', the facility will treat 3 million gallons of water daily, enough to meet the water needs of 300,000 people in Mithi and in 80 adjoining villages, according to officials in the Mithi town municipal office.

Constructed at a cost of 400 million Pakistani rupees or $4 million, the plant is expected to particularly benefit women, who currently often must fetch water from far-away hand-dug wells.

Sunita Bheel, a woman waiting in line for water from the new Mithi plant, said women in the area often walk two kilometers a day to fetch water from a hand-dug well owned by a landlord outside the village.



EFFECT ON MIGRATION

Local people said having water available for themselves, and their livestock, may stem increasing waves of migration from the area.

Anil Kumar, who lives in Morrey-Jee-Waand village, a few miles from Mithi, said 80 percent of people in his village and in seven other villages around it migrated last September to other areas in the region with supplies of dam water in an effort to find potable water for themselves and their livestock, and to seek jobs after crops failed.

"But they are now gradually returning to their villages when they learn about the sweet water (plant)," said the 65-year-old guar farmer, who looks after the property and belongings of neighbours who have migrated.

Today, Kumar rides every other day on his mule, strapped with two empty 30-liter drums, to the filtration plant to bring back water, he said.

Access to useable water is a key problem in drought-hit Tharparkar. Barely 5 percent of the population has access to clean and disease-free potable water, according to a study by Dow University of Health Sciences (DUHS) and the Pakistan Council for Scientific and Industrial Research (PCSIR).

One reason for this has been worsening fluoride contamination of underground water sources as less water recharges the drying system. The study found that the fluoride level at many locations in Tharparkar is at dangerous levels of over 13 mg/liter compared to the 1 mg/liter considered normal.

Excessive fluoride intake, from sources with more than 1.5 mg/liter of fluoride in the water, can cause problems such as bone deformation, dental problems, and damage to the kidneys and thyroid.

NO RAIN, NO RIVERS

Tharparkar depends heavily on rain-fed ground water, as it has no rivers. It receives an average annual rainfall between 200 and 300 millimetres, 80 percent of it during summer monsoon season, which runs from July to September. The rainfall recharges groundwater that must then last for the other three quarters of the year.

BBC on Thar:

The last time I was in Tharparkar in 2000 it was to report on one of the more severe droughts this region has experienced.
Fifteen years later, in some ways much has changed.
Back then, I remember travelling for hours on sandy tracks in a rickety old World War Two American truck called Kekra (meaning tortoise). These slow-moving trucks were the main mode of transport between border towns and the district capital Mithi. Today, there are shiny new roads linking most of the major towns in Thar.
Back then, radio was the only mass medium and news travelled by word of mouth. Today, the arrival of mobile phones in the main villages has transformed the way people can connect with each other and the rest of the world.
Electricity infrastructure is still lacking. But solar power has gained momentum.
Travelling in Thar these days, it is not uncommon to come across roadside vendors offering to charge your mobile phone using solar panels.
And yet, despite these improvements in communications, social sectors like health and education have continued to suffer.
Water scheme
This region has one of the highest infant mortality rates in the country. On most measures of development, Thar is at the bottom of Pakistan's 120 districts.
Doctors and nurses are hard to find. Qualified medical staff from the region often leave to earn much more money in big cities like Karachi.
In Thar, there are many villages without schools and many schools without teachers.

It's part of an overall crisis of governance, say critics. They blame the provincial government of Sindh - run by the party of former president Asif Ali Zardari - for corruption and institutional failures.
But the government defends its performance by pointing to its massive investment in a new scheme to bring clean drinking water to the region.
The $33m project involves installing 750 water purification projects in villages across the desert region. Of these, as of this month, about 280 have already been installed, says PakOasis, the company running the project.
The scheme is being billed as a ray of hope for Thar. It uses imported Danish technology to pump underground water. Impurities from the water are then removed using American membrane technology. The filtration process is called Reverse Osmosis (RO).
Each RO plant runs on zero-electricity cost. It is powered by solar panels imported from China.
The biggest of these water plants stands on a hill near Mithi. It has the capacity of purifying 2 million gallons of water daily. At its full capacity, it is expected to benefit 300,000 people.
The project was meant to go online later this year. But reeling under heavy public criticism for not doing enough, the government inaugurated it with much fanfare in January.

The owner of the world’s largest hydroelectric dam, China Three Gorges Corporation, is willing to participate in a financing consortium to fund up to $50 billion of hydroelectric power projects in Pakistan.

The Chinese government-owned CTG expressed an interest in financing projects in Pakistan in conjunction with the International Finance Corporation, a World Bank subsidiary. This disclosure was made at the meeting of the Cabinet Committee on Energy on June 18. The offer comes on top of the $46 billion in financing for power and transportation infrastructure being provided by the Chinese government and Chinese banks to Pakistan for the construction of the China-Pakistan Economic Corridor (CPEC).

If the offer pans out, it would make China the biggest financier of infrastructure in Pakistan by far. CTG owns and operates the Three Gorges Dam, the world’s largest hydroelectric power plant with a capacity of 22,500 megawatts, nearly matching in one power plant the entire installed capacity of the Pakistani grid of 23,500 MW.

Read: China-Pakistan Economic Corridor: Lines of development – not lines of divide

According to studies conducted by the Water and Power Development Authority, Pakistan has an identified potential of producing up to 60,000 MW of hydroelectric power, of which 40,000 MW is located in a region called the Indus Cascade, which begins in Skardu in Gilgit-Baltistan and runs through to Tarbela, the site of Pakistan’s biggest dam, in Khyber-Pakhtunkhwa.

The biggest project the government has already identified and begun preliminary work on is the Diamer Bhasha dam, which would require $15 billion to construct and would have a nameplate capacity of 4,500 MW.

Pakistan’s energy sources have gone through cycles. Up until the 1980s, the bulk of electricity in Pakistan came from hydroelectric power. In 1994, as the country’s energy needs surged, the government initiated a policy to attract private investment in thermal electricity. Oil prices were low in that decade and so the government made the decision to use oil-fired power plants, a decision that proved costly when oil surged to $100 a barrel, prompting Islamabad to search for cheaper ways of producing electricity. Among those cheap ways is hydroelectric power and coal-fired thermal electricity.

Among other projects the government wants to seek Chinese financing for is the Neelum-Jhelum power project in Azad Kashmir. The 969 MW Neelum-Jhelum hydroelectric power project has been facing rising costs, mainly due to the delays caused by a lack of funding. The project was initially slated to cost $1.8 billion, but will now cost $4.2 billion due to the delays, a major cause of concern for its initial consortium of Middle Eastern financiers which included the Islamic Development Bank (IDB), the Kuwait Fund for Development (KFD), the Saudi Fund for Development and the OPEC Development Fund.

The government now expects to raise Rs100 billion ($1 billion) in local borrowing for the plant, in addition to $576 million in foreign borrowing. The government has approached the state-owned National Bank of Pakistan to arrange financing for the local currency component. The Middle Eastern lenders have so far committed $692 million, of which they have disbursed $260 million so far.

“The disbursement of the remaining $433 million has been stopped by the lenders as they are demanding that the contractors should provide performance guarantee for the additional work (variation orders) and cost escalation,” said one source familiar with the cabinet’s deliberations on the matter.

Anti-drought measure in #Pakistan's Thar desert may also provide jobs. #desalination #FishFarming http://upi.com/5182059t via @upi

When officials in Pakistan's Sindh province constructed hundreds of desalination plants, they were only thinking of how to counter a long-running drought.

Along with providing much-needed drinking water, however, authorities hope to provide an economic boost and new jobs for the impoverished Thar majority – in the form of fish farms. They are planning to
populate the brackish water left behind by the desalination process.
"This is a revolutionary step, which will bring sustainable development in the area," Sen. Taj Haider, who heads the Thar Drought Relief Operation, told News Lens Pakistan. "It will also generate revenue, which will be spent for the local development."

Sindh's Thar Desert, which covers 77,000 square miles in southeastern Pakistan, has been in the grip of a drought since December 2013 that has left more than 1,000 dead, most of them children under the age of 5. The drought, blamed on a lack of rain, has also devastated agriculture and killed nearly 4,000 cows, sheep and goats.

As part of the massive relief operations, Sindh officials have launched plans to build hundreds of desalination plants that use reverse osmosis to covert salt water into drinking water. They promised to build 750, but so far have built 345.

When pure water is produced by reverse osmosis, thickly contaminated salty water is left behind.

Authorities came up with the fish farming plan to use that remaining salt water. They plan to collect the remaining water in tanks and use it for the fish farms. Farms are set to start operating this month and
will be funded by the Pak Oasis, the company that built the desalination plants – with a farm being constructed on the grounds of each facility.

So far, the plan has received a mixed reception from local residents. Some complain it will do nothing to alleviate the drought and may just be a short-term fix.

"Reverse osmosis plants are not a permanent solution," said Kanji Bheel, a resident of Chacharo city. "We need permanent solution, like a canal."

"The government is unable to save sheep for which desert is habitat. How can they introduce fish farming in the desert?," Bharumal Amrani, a social activist, told News Lens Pakistan. "It's nothing but a joke [for] the people of Thar."

Others are happy to find the desalination plants in their area and see the fish farms as a chance to make extra money.

"It always took long hours every day to fetch water, and even that water is brackish. But now we have filtered water at our doorstep," said Mohsin Ali Rahimoon, a resident of Bakhwo village.

The leaders of the University of Utah and Mehran University of Engineering and Technology traded memorandums of agreement Tuesday in the new campus law building, formalizing an academic partnership for water research.

Although the signing of a memorandum of agreement does not bind either party by law to uphold agreements made regarding the project, the documents are treated with the highest respect by both institutions.

"Utah and Pakistan surely share common ground in this sector. We both cope with water scarcity and the need for better ground management," University of Utah President David Pershing said.

The partnership will serve as a model of cooperation, address critical water issues and train the next generation's water professionals, Pershing said.

The educational partnership is part of a program known as United States-Pakistan Centers for Advanced Studies in Water and is funded by the United States Agency for International Development.

Academic programs resulting from the project will include master's and doctorate degrees in three water disciplines at Mehran University, which provides many opportunities for research and will be the primary center for the project because it's located in the water-stressed Sindh province of Pakistan.

According to M. Aslam Uqaili, vice chancellor of Mehran University, the higher education institution received nearly 500 applicants for 50 positions in the upcoming academic water programs.

Meanwhile, U. faculty, staff and students will have several research opportunities as they collaborate with Pakistani academics and five other partner institutions, including Colorado State University.

"It aligns very well with strategic priorities of our institution," said Ruth Watkins, head of academic affairs at the U.

Watkins said the partnership will help bring in expert faculty to the University of Utah, assist in achieving the school's environmental goals, and increase the presence of women in technology and science.

Participating parties are also hoping the pending research will address four overarching water problems in Pakistan: surface and groundwater availability, hazard and risk management, environmental quality, and climate change.

"The situation in Pakistan, as far as water scarcity is concerned both for human consumption as well as for agriculture, is something that really does need to be tackled," said Hamid Asghar Khan, consul general of Pakistan in Los Angeles.

In some areas of Pakistan, young children die from the lack of proper drinking water, Khan said.

Finding water solutions Pakistan is just the beginning. United States Agency for International Development officials are hoping new technology will be applicable to other water-stressed regions throughout the world.

Rainwater harvesting brings hope to farmers in #Pakistan’s #Punjab. #Water http://scroll.in/article/801240/rainwater-harvesting-brings-hope-to... … via @scroll_in

Extreme weather conditions and erratic rainfall had added an edge of desperation to Muhammad Khan’s struggle for survival, taking him and his family to the brink of ruin. But that is happily in the past now, says the farmer in Pakistan’s Punjab province whose life has undergone a dramatic change after he started irrigating his land from rainwater harvested in a small dam in the village.

“I had a bumper vegetable crop in the last season. I have recently bought a new tractor and also started sending two of my grandsons to a private school,” said the 65-year-old resident of Thoa Mehram Khan village in Punjab’s Talagang sub-district.

With the bounty of plentiful water, Khan has been irrigating 16 acres of his 50 acres of land from the small dam and growing off-season vegetables like tomatoes, potatoes and cauliflower as well as fruits such as grapes and watermelons. This was unthinkable earlier.

He is not the only one. Others in the village are also cultivating newer crops on land that was arid not so long ago. Rainwater harvesting is a relatively new and innovative concept for many farmers in the region who are delighted to have water for crops and livestock throughout the year.

“Rainwater harvesting has also helped raise the groundwater table from 450 feet to 200 feet in the village,” says Khan. “This is also inspiring people of nearby villages to pool money for building mini dams so they can reap the benefits of modern agriculture.”

To construct a mini dam for rainwater harvesting, a natural stream or nullah (water channel) near farmland is identified and then choked by building a wall in the front. An engine is installed and water supplied to farms through a pipeline.

The small dam, which is 15 feet in height, is built on government land in the village and has a catchment area of one square kilometre, a command area of 250 kanals (about 500 square metres) and storage capacity 29.21 acres/feet.

The cost of the $4,279 project, which has changed so many lives, was shared by 20 families of the village and by the International Fund for Agricultural Development, both sides paying $2,139, an official said.

The importance of harvesting water is underscored by a research paper published by the Pakistan Journal of Agricultural Sciences, which estimates that the Potohar Plateau, including the Chakwal, Jhelum, Attock and Rawalpindi districts of Punjab province, covers an area of 2.2 million hectares and receives as much as 70% of its precipitation in just the monsoon season.

On top of this, groundwater supplies are depleting at 16 to 55 centimetres (6 to 21 inches) a year across Punjab province, according to a study by the International Waterlogging and Salinity Research Institute.

Going macro

An estimated 64% of the country’s population lives in rural areas and earns a living from agricultural activities such as crop cultivation and livestock rearing, according to the 2010 agricultural census carried out by Pakistan Bureau of Statistics. There are 50,588 villages in Pakistan but all may not have terrain suitable for rainwater harvesting. The Potohar Plateau is believed to be the most suitable area in the country for natural places for rainwater harvesting with experts identifying 74 sites.

Around 145 million acre feet of water flows through Pakistan each year, but the country’s existing storage capacity is only 14 million acre feet. “Small dams and rainwater harvesting techniques could help the country increase its water storage capacity from 30 days to the international standard of 120 days,” said Dr Pervaiz Amir, country director for the Pakistan Water Partnership.

Answer to 's water security crisis could lie in 's Dasht River in Balochistan, says head of Geowash

ABU DHABI // The answer to the UAE’s water shortage could lie in a pipeline from Pakistan, according to an Emirati businessman.

Abdulla Al Shehi, chief executive of Geowash, has written a paper suggesting an underground pipeline from Dasht, a river 500 kilometres away in Pakistan, to Fujairah.

“Technology is not a problem. We are at an advanced stage in engineering where it is possible politically as well. I don’t think there will be any problem. It is beneficial for both countries,” he said.

He said the Dasht River floods annually, which prompted the Pakistani government to empty the excess water through channels leading to the sea. That excess water, said Mr Al Shehi, could be put to use in the UAE.

The idea may sound far-fetched, but Mr Al Shehi is something of a specialist in saving water.

Since its inception, Mr Al Shehi has run Geowash, which washes a car using only four litres of water, compared to the 220 litres conventional cleaning takes.

Mr Al Shehi’s technique has allowed the company to save 500 million litres of water since 2008.

The pipeline, if built, would not be the longest – that honour belongs to Turkey’s 9,300km pipeline in the Harran Plain.

Nor will it be the most difficult feat of engineering. However, it would face other issues that Mr Al Shehi admitted.

“There will be an environmental impact. There might be a negative effect, which I think is minor,” he said.

“However, the benefits in saving water from desalination and the amount of biological life it will spur will offset the effects.”

However, for Professor Hussein Amery, who wrote a book titled Arab Water Security, the concept of creating a pipeline is fraught with political issues.

“I won’t discuss the economics of engineering challenges. I am suspicious of a project of this sort, because let me remind you that Qatar and Kuwait both have explored importing water from south-west Iran,” he said.

The problem with creating cross-country pipelines, he said, was that it created a security situation where a nation is dependent on a neighbour – described by Prof Amery as “hydro-dependency”.

“Gulf-Pakistani relations are different than Gulf-Irani relations. I am totally aware of that, but the engineering would be challenging and difficult considering the terrain,” he said.

He said that the political and technological hurdles can be overcome, but even then, the idea still would not be efficient.

“We use a very small amount of water in our homes in the Gulf states,” he said.

“Anywhere between 70 to 80 per cent goes to agriculture.

“It’s much cheaper and much more efficient to have the Pakistanis grow wheat and feed cows, then export the food [than import the water and grow food locally].”

Furthermore, he said, the UAE relies heavily on a very energy-intensive water source.

“The biggest threat is that it [the UAE] is hyper-arid and it doesn’t have any permanent water source, which created the reliance on desalination technology, as such it has become the destiny for the Emirates and other Gulf states,” he said.

Dr Ahmad Belhoul, chief executive of Masdar, said although it is investing heavily in researching renewable energy to provide energy to desalination plants, he welcomed new ideas, especially as the year of innovation comes to a close.

“I think that the very spirit of creating a company like Masdar is to encourage people to come up with ideas, some which are very practical and others more ambitious,” he said. “Either way, it warms my heart that Emiratis and expats alike are thinking proactively of solutions.”

#Pakistan using #NASA satellite images to monitor, manage groundwater resources. http://phy.so/376039608 via @physorg_com

Pakistan's water managers are looking to NASA satellites to help them more effectively monitor and manage that precious resource, thanks to a partnership with engineers and hydrologists at the University of Washington, Seattle.
"Satellites up in space looking at how much water we have underground, in rivers or in the atmosphere are providing routine observations that can help policymakers and on-the-ground managers make informed decisions," said Faisal Hossain, associate professor of civil and environmental engineering at the University of Washington. "From offering improved flood forecasting to indicating areas where groundwater resources are threatened, freely available satellite data can be an invaluable resource, particularly in developing countries."

After training at the University of Washington, the Pakistan Council of Research in Water Resources in January 2016 began using satellite data from NASA's Gravity Recovery and Climate Experiment, or GRACE, mission to create monthly updates on groundwater storage changes in the Indus River basin. This will allow them to see where groundwater supplies are being depleted and where they are being adequately recharged. Like all NASA satellite data, GRACE data are freely available for download from open NASA data centers (GRACE Tellus and the Physical Oceanography Distributed Active Archive Center) at NASA's Jet Propulsion Laboratory in Pasadena, California.
GRACE's pair of identical satellites, launched in 2002, map tiny variations in Earth's gravity. Since water has mass, it affects these measurements. Therefore, GRACE data can help scientists monitor where the water is and how it changes over time. Using tools developed by the University of Washington and partners at the University of Houston; Ohio State University, Columbus; and NASA's Applied Sciences Program, Pakistan's water managers and researchers can analyze the NASA data to estimate changes in the total amount of available water, as well as changes in groundwater supplies.

"Using these satellites, we can indicate the areas that are most threatened by groundwater depletion. We can tell the farmers and water managers and help decision makers formulate better and more sustainable policies," said Naveed Iqbal, an assistant director and hydrogeologist at the Pakistan Council of Research in Water Resources. Iqbal spent six months at the University of Washington learning how to analyze and process the GRACE data to enhance decision-making at his agency.
GRACE project scientist Carmen Boening of JPL, which manages the GRACE project for NASA, said, "This is another great example of the unique ability of GRACE to see changes in water resources on a regional scale and provide easily accessible information where data are otherwise limited."
Compared to traditional groundwater monitoring efforts, the satellite information offers less spatial resolution but huge benefits in terms of cost and efficiency. For example, Pakistani water managers spent eight years building a groundwater monitoring network in the Indus River basin alone, and that network provides readings only twice a year.
"It's so fundamentally difficult to do this monitoring in a conventional way—sending people and sticking probes in the ground to measure water. It takes a long time and it's expensive," said Hossain, who runs the University of Washington's Sustainability, Satellites, Water and Environment Research Group. "In some places you can't even send people because the terrain is too remote or there is mortal danger due to insurgency and political strife."

BBC News - Is facing its worst-ever crisis?

On 11 March, panic struck engineers at a giant power station on the banks of the Ganges river in West Bengal state.

Readings showed that the water level in the canal connecting the river to the plant was going down rapidly. Water is used to produce steam to run the turbines and for cooling vital equipment of coal-fired power stations.

By next day, authorities were forced to suspend generation at the 2,300-megawatt plant in Farakka town causing shortages in India's power grid. Next, the vast township on the river, where more than 1,000 families of plant workers live, ran out of water. Thousands of bottles of packaged drinking water were distributed to residents, and fire engines rushed to the river to extract water for cooking and cleaning.

'Shortage of water'

The power station - one of the 41 run by the state-owned National Thermal Power Corporation, which generates a quarter of India's electricity - was shut for 10 days, unprecedented in its 30-year history.

"Never before have we shut down the plant because of a shortage of water," says Milan Kumar, a senior plant official.

"We are being told by the authorities that water levels in the river have receded, and that they can do very little."

Further downstream, say locals, ferries were suspended and sandbars emerged on the river. Some 13 barges carrying imported coal to the power station were stranded midstream because of insufficient water. Children were seen playing on a near-dry river bed.

Nobody is sure why the water level on the Ganges receded at Farakka, where India built a barrage in the 1970s to divert water away from Bangladesh. Much later, in the mid-1990s, the countries signed a 30-year agreement to share water. (The precipitous decline in water levels happened during a 10-day cycle when India is bound by the pact to divert most of the water to Bangladesh. The fall in level left India with much less water than usual.)

Monsoon rains have been scanty in India for the second year in succession. The melting of snow in the Himalayas - the mountain holds the world's largest body of ice outside the polar caps and contributes up to 15% of the river flow - has been delayed this year, says SK Haldar, general manager of the barrage. "There are fluctuations like this every year," he says.

'Filthy river'

But the evidence about the declining water levels and waning health of the 2,500km (1,553 miles)-long Ganges, which supports a quarter of India's 1.3 billion people, is mounting.

Part of a river's water level is determined by the groundwater reserves in the area drained by it and the duration and intensity of monsoon rains. Water tables have been declining in the Ganges basin due to the reckless extraction of groundwater. Much of the groundwater is, anyway, already contaminated with arsenic and fluoride. A controversial UN climate report said the Himalayan glaciers could melt to a fifth of the current levels by 2035.

Emmanuel Theophilus and his son, Theo, kayaked on the Ganges during their 87-day, 2,500km journey of India's rivers last year. They asked fishermen and people living on the river what had changed most about it.

"All of them said there had been a reduction in water levels over the years. Also when we were sailing on the Ganges, we did not find a single turtle. The river was so dirty that it stank. There were effluents, sewage and dead bodies floating," says Mr Theophilus.

The waning health of the sacred river underscores the rising crisis of water in India. Two successive bad monsoons have already led to a drought-like situation, and river basins are facing water shortages.

Water conflicts

The three-month-long summer is barely weeks away but water availability in India's 91 reservoirs is at its lowest in a decade, with stocks at a paltry 29% of their total storage capacity, according to the Central Water Commission. Some 85% of the country's drinking water comes from aquifers, but their levels are falling, according to WaterAid.

No wonder then that conflicts over water are on the rise.

    Biden's Gaza Ceasefire Veto Defies American Public Opinion

    Aaron Bushnell, an active serviceman in the United States Air Force, burned himself to death in front of the Israeli Embassy in protest against the US policy in Gaza. Before setting himself on fire in what he called an "extreme act of protest", he said he would "no longer be complicit in genocide". Polls show that the vast majority (63%) of Americans want an immediate end to the carnage being perpetrated by Israel in Gaza.  …
