According to a recent report by the International Monetary Fund (IMF), Pakistan ranks third in the world among countries facing acute water shortage. Reports by the United Nations Development Programme (UNDP) and the Pakistan Council of Research in Water Resources (PCRWR) also warn the authorities that the South Asian country will reach absolute water scarcity by 2025.

"No person in Pakistan, whether from the north with its more than 5,000 glaciers, or from the south with its 'hyper deserts,' will be immune to this [scarcity]," said Neil Buhne, UN humanitarian coordinator for Pakistan.

Researchers predict that Pakistan is on its way to becoming the most water-stressed country in the region by the year 2040.

It is not the first time that development and research organizations have alerted Pakistani authorities about an impending crisis, which some analysts say poses a bigger threat to the country than terrorism.

In 2016, PCRWR reported that Pakistan touched the "water stress line" in 1990 and crossed the "water scarcity line" in 2005. If this situation persists, Pakistan is likely to face an acute water shortage or a drought-like situation in the near future, according to PCRWR, which is affiliated with the South Asian country's Ministry of Science and Technology.

2017: Devastating effects of climate change Sweltering heat Unprecedented heat waves swept across the globe in 2017, leading to droughts, wildfires and even deaths. Australia started the year with temperatures near 50 degrees Celsius (122 Fahrenheit), the "Lucifer" heat wave brought the mercury above 40 degrees Celsius throughout Southern Europe in July and August and scorching heat hit India's most vulnerable people. Get ready for next summer...

2017: Devastating effects of climate change Disappearing wonder Earlier this year, scientists realized that coral bleaching in Australia's Great Barrier Reef was worse than first thought. In some parts of the UNESCO World Heritage site, up to 70 percent of the coral has already been killed. By 2050, scientists have warned 90 percent of the reef could disappear. Rising sea temperatures and ocean acidification are the main culprits.

2017: Devastating effects of climate change Deadly combination Armed conflicts are pushing millions of people to leave their homes or live in terribly precarious situations — and climate change is making it worse. A lack of natural resources increases the risk of conflict and makes life even harder for refugees. South Sudanese families, for instance, are escaping to neighboring countries like Uganda and Kenya — countries already suffering from drought.

2017: Devastating effects of climate change World on fire From New Zealand to Spain, from California to even Greenland: the world has seen a nonstop year of wildfires. Global warming has been blamed for the increased fire risk, and in some countries that risk has turned into reality. Wildfires engulfed large areas of Europe's Iberian Peninsula, causing death and destruction, while firefighters in California have had no rest for more than six months.

2017: Devastating effects of climate change Record-shattering storms Hurricanes Maria and Irma, which hit the Caribbean region in August and September, were two of the year's most damaging weather events. The list of deadly storms also included Ophelia in Ireland, Harvey and Nate in Central America and the US, and Xavier and Sebastian in Germany. Warming of the ocean surface has led to more evaporation, and that water may help fuel thunderstorms and hurricanes.

2017: Devastating effects of climate change Melting Antarctica In July, one of the largest icebergs ever recorded separated from the Larsen C ice shelf — one of Antarctica's biggest — reducing its area by more than 12 percent. While calving icebergs in the Antarctic are part of a natural cycle, scientists have linked the retreat of several Antarctic ice shelves to global warming and are closely monitoring potential long-term effects.

2017: Devastating effects of climate change Struggle to breathe Deteriorating air quality causes thousands of deaths around the world every year. India's capital, New Delhi, is one of the world's most polluted cities. In November, large parts of northern India and Pakistan were engulfed by a blanket of thick smog carrying harmful particulate matter. Schools were forced to close, and hospitals were full of people with respiratory problems.

2017: Devastating effects of climate change Oceans at risk The high levels of carbon dioxide in the atmosphere represent a major threat for our oceans, already in danger due to plastic pollution, overfishing and warming waters. Ocean acidification could make these waters — covering more than two-thirds of our planet's surface — a hostile environment for sea creatures. And without marine animals, entire ocean ecosystems are at risk.

2017: Devastating effects of climate change Fierce floods and mudslides Superstorms often trigger flash floods and mudslides. In late December, more than 230 people were killed when a storm hit the Philippines' second-largest island of Mindanao, a tragedy exacerbated by years of deforestation. In 2017, severe floods also hit countries such as Vietnam, Peru and Sierra Leone. European countries, including Greece and Germany, also felt the damaging effects of heavy rain.

A water-intensive country

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.

According to the IMF, Pakistan's per capita annual water availability is 1,017 cubic meters — perilously close to the scarcity threshold of 1,000 cubic meters. Back in 2009, Pakistan's water availability was about 1,500 cubic meters.

The bulk of Pakistan's farmland is irrigated through a canal system, but the IMF says in a report that canal water is vastly underpriced, recovering only a quarter of annual operating and maintenance costs. Meanwhile, agriculture, which consumes almost all annual available surface water, is largely untaxed.

Experts say that population growth and urbanization are the main reasons behind the crisis. The issue has also been exacerbated by climate change, poor water management and a lack of political will to deal with the crisis.

"Pakistan is approaching the scarcity threshold for water. What is even more disturbing is that groundwater supplies — the last resort of water supply — are being rapidly depleted. And worst of all is that the authorities have given no indication that they plan to do anything about any of this," Michael Kugelman, South Asia expert at the Washington-based Woodrow Wilson Center, told DW in a 2015 interview.

Qazi Talhat, a secretary at the Ministry of Water Resources, told DW the situation is "scary" for Pakistan.

Water scarcity is also triggering security conflicts in the country. Experts say the economic impact of the water crisis is immense, and the people are fighting for resources.

Climate change

Water scarcity in Pakistan has been accompanied by rising temperatures. In May, at least 65 people died from heatstroke in the southern city of Karachi. In 2015, at least 1,200 people died during a spate of extremely hot weather.

"Heat waves and droughts in Pakistan are a result of climate change," Mian Ahmed Naeem Salik, an environmental expert and research fellow at the Institute of Strategic Studies in Islamabad, told DW.

"The monsoon season has become erratic in the past few years. The winter season has shrunk from four to two months in many parts of the country. On top of it, Pakistan cannot save floodwater due to a scarcity of dams," Salik said. "At the time of Pakistan's birth in 1947, forests accounted for about 5 percent of the nation's area, but they have now dropped to only 2 percent. Pakistan must invest in building water reservoirs and plant more trees," he added.

Water politics

The Tarbela and Mangla dams, the country's two major water reservoirs, reached their "dead" levels last week, according to media reports. The news sparked a debate on social media over the inaction of authorities in the face of this crisis.

"We have only two big reservoirs and we can save water only for 30 days. India can store water for 190 days whereas the US can do it for 900 days," Muhammad Khalid Rana, a spokesman for the Indus River System Authority (IRSA), told DW.

"Pakistan receives around 145 million acre feet of water every year but can only save 13.7 million acre feet. Pakistan needs 40 million acre feet of water but 29 million acre feet of our floodwater is wasted because we have few dams. New Delhi raised this issue with international bodies, arguing that it should be allowed to use the western rivers because Pakistan can't use them properly," Rana said.

In 1960, the World Bank brokered the Indus Water Treaty (IWT) that gives Pakistan exclusive rights to use the region's western rivers — Indus, Jhelum and Chenaub — while India has the authority over three eastern rivers.

The Pakistani government says New Delhi is not fulfilling its responsibilities under the IWT as it voices concerns over India's construction of new dams. New Delhi is building the Kishangaga hydroelectric plant in the north of Bandipore in India-administered Jammu and Kashmir region. In May, Islamabad approached the World Bank complaining that India violated the IWT by building the dam on a Jehlum River basin, which it lays claim on.

Kugelman says that the Pakistani authorities need to step up efforts to overcome the water crisis, which is partly man-made. "First of all, Pakistan's leaders and stakeholders need to take ownership of this challenge and declare their intention to tackle it. Simply blaming previous governments, or blaming India, for the crisis won't solve anything. Next, the government needs to institute a major paradigm shift that promotes more judicious use of water," Kugelman emphasized.

Wastage of water

Apart from the water storage issue, experts say that water wastage is also a big issue in the country. Abid Suleri, executive director of the Islamabad-based Sustainable Development Policy Institute, says the mismanagement takes place at many levels.

As the water crisis worsens in Pakistan, foreign diplomats and activists have taken to social media, urging people to save water.

"Using a bucket to save water while washing my car! #Pakistan ranks third amongst countries facing water shortage. One major reason is excessive use. 100 liters wasted washing a car with running tap water. Many ways to #SaveWater in our daily life! #SaveWaterforPak," Martin Kobler, German ambassador to Pakistan, wrote on Twitter.

In April, former PM Shahid Khaqan Abbasi announced Pakistan's first National Water Policy, promising consolidated efforts to tackle the water crisis.

But experts are skeptical about the authorities will to deal with the issue. The country will hold general elections on July 25 and there is an interim government currently in place. Water crisis is a priority neither for the caretaker government nor for the political parties contesting the polls.
