Pakistan Water Crisis: Facts and Myths

[Riaz Haq]

Pakistan is believed to be in the midst of a water crisis that is said to pose an existential threat to the country. These assertions raise a whole series of questions on the source of the crisis and possible solutions to deal with it. The New Water Policy adopted in April 2018 is a good start but it needs a lot more focus and continuing investments.

Questions on Water Crisis: 

How severe is Pakistan's water crisis? Is India contributing to this crisis? How many million acre feet (MAF) of water flows in Pakistan? What are its sources? Glaciers? Rain? Groundwater? How much of it is stored in dams and other reservoirs? What is the trend of per capita water availability in Pakistan? What sectors are the biggest consumers of water in Pakistan? Why does agriculture consume over 95% of all available water? How can Pakistan produce "more crop per drop"? What are Pakistan's options in dealing with the water crisis? Build more dams? Recharge groundwater? Use improved irrigation techniques like sprinklers and drip irrigation? Would metering water at the consumers and charging based on actual use create incentives to be more efficient in water use?

Water Availability: 

Pakistan receives an average of 145 million acre feet (MAF) of water a year, according to the Indus River System Authority (IRSA) report. Water availability at various canal headworks is about 95 million acre feet (MAF).  About 50%-90% comes from the glacial melt while the rest comes from monsoon rains.  Additional 50 MAF of groundwater is extracted annually via tube wells.

The total per capita water availability is about 900 cubic meters per person, putting Pakistan in the water-stressed category.

India Factor: 

What is the impact of India's actions on water flow in Pakistan? Under the Indus Basin Water Treaty, India has the exclusive use of the water from two eastern rivers: Ravi and Sutlej. Pakistan has the right to use all of the water from the three western rivers: Chenab, Jhelum and Indus. However, India can build run of the river hydroelectric power plants with minimal water storage to generate electricity.

Currently, India is not using all of the water from the two eastern rivers. About 4.6 million acre feet (MAF) of water flows into Pakistan via Ravi and Sutlej. Water flow in Pakistan will be reduced if India decides to divert more water from Ravi and Sutlej for its own use.

Secondly, India can store water needed for run-of-the-river hydroelectric plants on the western rivers. When new hydroelectric projects are built on these rivers in India, Pakistan suffers from reduced water flows during the periods when these reservoirs are filled by India. This happened when Baglihar dam was filled by India as reported by Harvard Professor John Briscoe who was assigned by the World Bank to work on IWT compliance by both India and Pakistan.

Pakistan is also likely to suffer when India ensures its hydroelectric reservoirs are filled in periods of low water flow in the three western rivers.

Water Storage Capacity: 

Pakistan's water storage capacity in its various dams and lakes is about 15 million acre feet (MAF), about 10% of all water flow. It's just enough water to cover a little over a month  of water needed. There are several new dams in the works which will double Pakistan's water storage capacity when completed in the future.

Since 1970s, the only significant expansion in water storage capacity occurred on former President Musharraf's watch when Mangla Dam was raised 30 feet to increase its capacity by nearly 3 million acre feet (MAF). Musharraf increased water projects budget to Rs. 70 billion which was reduced to Rs. 51 billion by PPP government and further decreased to Rs. 36 billion by PMLN government.  It was only the very last PMLN budget passed by Shahid Khaqan Abbasi's outgoing government that increased water development allocation to Rs. 65 billion, a far cry from Rs. 70 billion during Musharraf years given the dramatic drop in the value of the Pakistani rupee.

Water Consumption: 

Domestic, business and industrial consumers use about 5 million acre feet while the rest is consumed by the agriculture sector to grow food. Just 5% improvement in irrigation efficiency can save Pakistan about 7.5 million acre feet , the same as the current storage capacity of the country's largest Tarbela dam.

Given the vast amount of water used to grow crops, there is a significant opportunity to save water and increase yields by  modernizing the farm sector.

National Water Policy:

Pakistan's Common Council of Interests (CCI) with the prime minister and the provincial chief ministers recently adopted a National Water Policy (NWP) in April 2018. It is designed to deal with “the looming shortage of water” which poses “a grave threat to (the country’s) food, energy and water security” and constitutes “an existential threat…”as well as “the commitment and intent” of the federal and provincial governments to make efforts “ to avert the water crisis”.

The NWP supports significant increases in the public sector investment for the water sector by the Federal Government from 3.7% of the development budget in 2017-18 to at least 10% in 2018-19 and 20% by 2030; the establishment of an apex body to approve legislation, policies and strategies for water resource development and management, supported by a multi- sectoral Steering Committee of officials at the working level; and the creation of a Groundwater Authority in Islamabad and provincial water authorities in each of the provinces.

More Crop Per Drop:

"More crop per drop" program will focus on improving water use efficiency by promoting drip and sprinkler irrigation in agriculture.

The Punjab government started this effort with the World Bank with $250 million investment.  The World Bank is now providing additional $130 million financing for the Punjab Irrigated Agriculture Productivity Improvement Program Phase-I.

The project is the Punjab Government's initiative called High-Efficiency Irrigation Systems (HEIS) to more than doubles the efficiency of water use. Under the project, drip irrigation systems have been installed on about 26,000 acres, and 5,000 laser leveling units have been provided. The additional financing will ensure completion of 120,000 acres with ponds in saline areas and for rainwater harvesting, and filtration systems for drinking water where possible, according to the World Bank.

Groundwater Depletion: 

 Pakistan, India, and the United States are responsible for two-thirds of the groundwater use globally,  according to a report by University College London researcher Carole Dalin.  Nearly half of this groundwater is used to grow wheat and rice crops for domestic consumption and exports.  This puts Pakistan among the world's largest exporters of its rapidly depleting groundwater.

Pakistan Council of Research in Water Resources is working with  United States' National Air and Space Administration (NASA) to monitor groundwater resources in the country.

Water Stress Satellite Map Source: NASA

NASA's water stress maps shows extreme water stress across most of Pakistan and northern, western and southern parts of India.

The US space agency uses Gravity Recovery and Climate Experiment (GRACE) to measure earth's groundwater. 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, according to NASA.

Aquifer Recharge:

Building large dams is only part of the solution to water stress in Pakistan. The other, more important part, is building structures to trap rain water for recharging aquifers across the country.

Typical Aquifer in Thar Desert

Pakistan's highly water stressed Punjab province is beginning recognize the need for replacing groundwater. Punjab Government is currently in the process of planning a project to recharge aquifers for groundwater management in the Province by developing the economical and sustainable technology and to recharge aquifer naturally and artificially at the available site across the Punjab. It has allocated Rs. 582.249 million to execute this project over four years.

Summary:

Pakistan is in the midst of a severe water crisis that could pose an existential threat if nothing is done to deal with it.  The total per capita water availability is about 900 cubic meters per person, putting the country in the water-stressed category. Agriculture sector uses about 95% of the available water. There are significant opportunities to achieve greater efficiency by using drop irrigation systems being introduced in Punjab. The New Water Policy is a good start but it requires continued attention with greater investments and focus to deal with all aspects of the crisis.

Sindh has become the only province to possess as many as 50 operational small dams that aim to meet the water needs of far-flung areas. As many as 31 new dams are under construction while some eight area are under the tendering process, it is learnt.

https://www.pakistantoday.com.pk/2018/09/12/sindh-becomes-only-prov...


According to the Small Dams Organization chief engineer, the Sindh government had launched a number of small dams, with a total cost of Rs 12,211 million, to contain water crisis in the districts. Various potential sites were identified for small water reservoirs, particularly along the Kirthar mountain on the western side of the province, he added.

“There are strong opportunities to store rainwater in natural catchments of the Kirthar hills which can be used for cultivation, livestock and human consumption on sustainable basis,” he said, adding that the Kirthar mountain range, shared by Balochistan and Sindh, extends southward for about 300km from the Mula River in east-central Balochistan to the Cape Muari, west of Karachi on the Arabian Sea.

The chief engineer said the areas identified for small dams include upper Kohistan, lower Kohistan, central Kohistan, Nagarparkar and Khairpur.

Advisor to Chief Minister on Information and Archives, Anti-Corruption and Law Barrister Murtaza Wahab told Pakistan Today that total of 50 small dams have so far been completed out of which 28 dams are completed under the province’s Annual Development Plan (ADP) while 22 dams are under the federally-funded Public Sector Development Programme (PSDP).

Barrister Wahab said that the number of total proposed dams stands at 122 and the provincial government is committed to accomplish all the dams at the earliest so as to end the prevalent water crisis in the province. Among these, he added, some 12 dams are located in Nagarparkar–Mithi, while 14 dams in Kohistan-I Dadu and 24 dams in Kohistan-II Jamshoro range.

Under the ADP schemes, the dams which have been completed include Ranpur bund, Mulji, Bhodesar Tank, Khararo Bund, Tobirio Tank, Lakhy-Jo-Wandio, Salari, Makhi, Rani Kot, Bandhani-I, Taki, Maliriri, Mohan, Ashoro Kuch, Suku, Koteri, Thado-II, Langheji, Nai-Mango, Kalu-1, Jharando, Sari, Malir Memon Goth Weir, Kataro, Meer Chakar, Mole Nadi, German Dhoro and Ranpathani.

Managing Groundwater Resources in Pakistan’s Indus Basin

https://www.worldbank.org/en/news/feature/2021/03/25/managing-groun...

Highlights
Improved groundwater management is crucial for a healthy, wealthy, and green Pakistan. Pakistan’s Indus Basin Irrigation System is the largest artificial groundwater recharge system in the world, but the current water management paradigm doesn’t reflect it.
Over-abstraction, waterlogging and contamination threaten the crucial role of groundwater as a life-sustaining resource, which has cascading impacts on drought resilience, public health, and environmental sustainability.
For groundwater to remain a safe and reliable source of drinking water and a lifeline for tail-end farmers, a balance must be achieved between efficiency of the surface water system and sustainability of groundwater resources.

----------

In the past, these challenges were aggravated by an inadequate policy framework, lack of regulation and insufficient investments. Unregulated pumping has led to groundwater depletion and the drying up of wells in parts of Punjab. Excess irrigation in areas where groundwater levels are high is contributing to widespread waterlogging in Sindh. An increasing volume of unmanaged domestic and industrial wastewater is seeping into the ground, adding to the cocktail of contaminants affecting drinking water supplies. Inadequate data collection has inhibited the ability to adopt evidence-based policies to improve groundwater management.

Improving groundwater management, however, is integral to Pakistan’s economic development. According to the World Bank report Pakistan: Getting More from Water, without necessary reform and better demand management in the water sector, water scarcity will constrain Pakistan from reaching upper middle-income status by 2047.

In recent years, Pakistan has taken steps towards addressing modern groundwater challenges, starting with the National Water Policy 2018 which identified priorities for groundwater management. This was followed by the Punjab Water Policy in 2018 and the Punjab Water Act 2019. The policy emphasizes the need to curb groundwater over-abstraction and contamination, and the Act establishes a regime of licenses for abstraction and wastewater disposal, managed by newly created regulatory bodies.

Punjab is also developing a provincial Groundwater Management Plan. In Khyber Pakhtunkhwa province, a similar act was passed in 2020 while in Sindh, a draft Water Policy is underway to provide much needed direction for tackling waterlogging and salinity, and for conjunctive management of surface water and groundwater. The federal government is drafting a five-year National Groundwater Management Plan to provide a framework for coordinating groundwater stakeholders across Pakistan.

These are important first steps. Going forward, the challenge will be to implement and deepen these initial reforms to ensure the long-term sustainability of Pakistan’s vital groundwater resources.

Groundwater in Pakistan’s Indus Basin: Present and Future Prospects proposes a roadmap to improve groundwater management, focusing on four intervention areas: appointing a coordinating agency that is accountable for groundwater management across all sectors in each province; establishing a modern groundwater database; managing water resources conjunctively; and improving groundwater quality.

As the last 100 years have shown, the Indus Basin’s groundwater challenges are complex and varied and demand an adaptive management response. Recent reforms in parts of the basin provide a basis for a more ambitious groundwater agenda, including the calculation of water budgets, wider engagement of stakeholders, comprehensive monitoring of water balances to manage waterlogging and depletion, the identification of opportunities for managed aquifer recharge, and a more rigorous approach towards safeguarding water quality.

Storing floodwater to ensure availability for whole year

https://www.thenews.com.pk/print/855127-storing-floodwater-to-ensur...

Islamabad : The government is likely to approve an ambitious plan to store floodwater in existing fifteen natural lakes linked with wetlands that would be a nature-based solution of its own kind in the country.

A high official of the climate change ministry told this correspondent that an international organization has recently submitted a report that stated that Pakistan stored only 9 percent of floodwater and the remaining amount went down to the Arabian Sea.

He said “The report pointed out that the melting of glaciers starts in the northern region and monsoon arrives from the southern region. All this happens within 100 days so the flow of water can be turned towards the natural lakes that are part of the wetland sites.”

The official said the natural lakes linked with wetlands can provide enough storage capacity and considerably ensure availability of water throughout the year.

He said there are one million tubewells in Pakistan due to which the level of underground water has reduced in last few decades, adding “The plan will also help recharge aquifer and raise the level of underground water. The whole country will benefit from this plan that is likely to be approved soon by the federal cabinet.”

Special Assistant to the Prime Minister on Climate Change Malik Amin Aslam has said the government is finding out nature-based solutions to the issue of water storage in the country. He said: “We have received a report from an international organization and it has shown us a path to store floodwater in existing natural lakes.”

These natural lakes are currently losing their water level so the plan would not only restore them to their original status but also help raise the level of groundwater in Pakistan, he said.

#California Has Some of #America’s Richest Farmland. But What Is It Without #Water? California farmers are selling their water for profits instead of growing crops amid severe #drought. #ClimateCrisis #Drought2021 https://www.nytimes.com/2021/06/28/climate/california-drought-farmi...

n America’s fruit and nut basket, water is now the most precious crop of all.

It explains why, amid a historic drought parching much of the American West, a grower of premium sushi rice has concluded that it makes better business sense to sell the water he would have used to grow rice than to actually grow rice. Or why a melon farmer has left a third of his fields fallow. Or why a large landholder farther south is thinking of planting a solar array on his fields rather than the thirsty almonds that delivered steady profit for years.

“You want to sit there and say, ‘We want to monetize the water?’ No, we don’t,” said Seth Fiack, a rice grower here in Ordbend, on the banks of the Sacramento River, who this year sowed virtually no rice and instead sold his unused water for desperate farmers farther south. “It’s not what we prefer to do, but it’s what we kind of need to, have to.”

These are among the signs of a huge transformation up and down California’s Central Valley, the country’s most lucrative agricultural belt, as it confronts both an exceptional drought and the consequences of years of pumping far too much water out of its aquifers. Across the state, reservoir levels are dropping and electric grids are at risk if hydroelectric dams don’t get enough water to produce power.

Climate change is supercharging the scarcity. Rising temperatures dry out the soil, which in turn can worsen heat waves. This week, temperatures in parts of California and the Pacific Northwest have been shattering records.

By 2040, the San Joaquin Valley is projected to lose at least 535,000 acres of agricultural production. That’s more than a tenth of the area farmed.

And if the drought perseveres and no new water can be found, nearly double that amount of land is projected to go idle, with potentially dire consequences for the nation’s food supply. California’s $50 billion agricultural sector supplies two-thirds of the country’s fruits and nuts and more than a third of America’s vegetables — the tomatoes, pistachios, grapes and strawberries that line grocery store shelves from coast to coast.

Glimpses of that future are evident now. Vast stretches of land are fallow because there’s no water. New calculations are being made about what crops to grow, how much, where. Millions of dollars are being spent on replenishing the aquifer that has been depleted for so long.

#Pakistan faces an existential crisis with fast melting glaciers. It has more glaciers outside of the polar icecaps than anywhere on earth. The glaciers feed one of the oldest and most fertile valleys on the planet. #water #agriculture #food https://aje.io/rnedz9 via @AJEnglish


The UN’s Intergovernmental Panel on Climate Change (IPCC) published its latest report in August 2021, on the heels of one of the hottest and most devastating summers on record: floods in northern Europe and China, wildfires in the US, and heatwaves everywhere.

The report tells us that the consequences of the current global warming crisis are largely irreversible. The most we can do is to prevent all-out ecological collapse.

One of the more sobering findings of the report is that polar and mountain glaciers are likely going to continue to melt, irreversibly, for decades or centuries to come.

Pakistan has more glaciers outside of the polar icecaps than anywhere on earth. The glaciers feed one of the oldest and most fertile valleys on the planet – that of the Indus Basin, split between India and Pakistan. Roughly 75 percent of Pakistan’s 216 million population is settled on the banks of the Indus River. Its five largest urban centres are entirely dependent on the river for industrial and domestic water.

Pakistan has been blessed with regular agricultural cycles that have sustained its economy through successive crises. However, if the IPCC Report is correct – which it almost certainly is – by 2050, the country will be out of water.

Pakistan is not the only low-income country facing the impacts of climate change. It is not alone in looking on helplessly as industrialised nations – China and the US being the foremost – drag their heels on lowering emissions. Pakistan, like the Maldives and many other island nations, will suffer from the consequences of global warming disproportionately. However, unlike many countries that have taken up the issue of global emissions at the UN, Pakistan is not doing even the bare minimum to try and secure its future.

To say that this is the largest security issue the country will face in the next few decades would be putting it mildly. No other country is as dependent on non-polar ice for freshwater as Pakistan. No other country stands to lose as much. Yet, Pakistan’s government seems singularly unaware of the looming crisis. It has not even made much effort to meet its target of producing 60 percent of its electrical power from renewable sources by 2030. At the moment, the country still gets well over 60 percent of its electricity from fossil fuels.

Pakistan is already facing mounting environmental challenges. Heatwaves are killing scores of people and impacting crop cycles and yields on a regular basis. This year, both its largest city Karachi and its capital city Islamabad experienced devastating floods. Furthermore, the 806-kilometre (500-mile) Karakoram Highway, which is a critical part of Pakistan’s economic corridor with China, was shut down multiple times, for multiple days, due to landslides. These devastating landslides were a direct result of large-scale deforestation in the area north of Kohistan and south of Jaglot. Further north towards Shimshal and east towards the Skardu Valley, timber mafias are rapidly stripping old-growth forests, all but guaranteeing future environmental catastrophes.




---------------------

Today, Pakistan is facing an existential crisis. The effects of climate change are not threatening a single sector or region of the country, but the lives and livelihoods of its entire population. As this year’s IPCC report underlined, we are, sadly, already too late to reverse the damage caused by the rampant consumption of fossil fuels. The choice we are facing now – in Pakistan and around the world – is to continue on a path to certain destruction, or start fighting for our collective survival.

Pakistan Water and Power Development Authority (WAPDA) is executing the biggest-ever portfolio of development projects in Pakistan including Diamer Basha Dam, Dasu Hydropower Project and Mohmand Dam worth $26 billion after a span of almost five decades by adopting an innovative financing strategy on the back of a robust capital structure and strong balance sheet footing.

https://nation.com.pk/11-Nov-2021/wapda-executing-projects-worth-do...


WAPDA Chairman Lt Gen Muzammil Hussain (retd) highlighted this in the meeting with a delegation of JP Morgan comprising senior representatives namely Asif Raza, Managing Director Global Corporate Bank CEEMEA, Imran Zaidi, Managing Director Global Corporate Bank covering Middle East and North Africa (MENA) and Amin M Khawaja, Chief Executive Officer Pakistan. WAPDA Member (Finance) Naveed Asghar was also present on the occasion.

Giving a run-down of 10 under construction WAPDA projects, the chairman said that these projects would enhance water storage capacity by more than 11 MAF and add another 9,000 MW of hydel electricity to the system. WAPDA has unparalleled institutional capacity to identify and implement multipurpose hydropower projects. It has adopted a multi-pronged strategy including Green Eurobonds and Syndicate loans etc for implementation of its projects. This was a radical shift from entire reliance on the Government of Pakistan. WAPDA’s business model has an important role to play in the development of a sustainable and lower-carbon economy in Pakistan, he said. The chairman said that WAPDA would continue to approach the international financial and capital market in a staggered mode, to minimise financing cost, in line with its financing requirements and would look forward to bring further investments in the hydropower sector which would go a long way to reduce carbon footprint in the power generation sector of Pakistan. He appreciated the role played by JP Morgan as the lead arranger for WAPDA’s debut Green Eurobond issuance alongside Deutsche, Standard Chartered and HBL Bank.

A century of groundwater accumulation in Pakistan and northwest India

https://www.nature.com/articles/s41561-022-00926-1

The groundwater systems of northwest India and central Pakistan are among the most heavily exploited in the world. However, recent, and well-documented, groundwater depletion has not been historically contextualized. Here, using a long-term observation-well dataset, we present a regional analysis of post-monsoon groundwater levels from 1900 to 2010. We show that human activity in the early twentieth century increased groundwater availability before large-scale exploitation began in the late twentieth century. Net groundwater accumulation in the twentieth century, calculated in areas with sufficient data, was at least 420 km3 at ~3.6 cm yr–1. The development of the region’s vast irrigation canal network, which increased groundwater recharge, played a defining role in twentieth-century groundwater accumulation. Between 1970 and 2000, groundwater levels stabilized because of the contrasting effects of above-average rainfall and the onset of tubewell development for irrigation. Due to a combination of low rainfall and increased tubewell development, approximately 70 km3 of groundwater was lost at ~2.8 cm yr–1 in the first decade of the twenty-first century. Our results demonstrate how human and climatic drivers have combined to drive historical groundwater trends.

Pakistan has the world's fourth-highest rate of water use. Its water intensity rate — the amount of water, in cubic meters, used per unit of GDP — is the world's highest. This suggests that no country's economy is more water-intensive than Pakistan's. 1/n
