As its population explodes, Pakistan stares at a future where it will be a water scarce country, but currently there is little new thinking in the government on how to tackle the crisis.
Dams, dams and more dams – of all sizes and kinds need to be built on a war footing because failing to do so would be disastrous for Pakistan.
This was the vehement and unanimous conclusion from scientists, water experts, agriculturists and climatologists who gathered for a 2-day workshop titled, "The Indus Basin Challenge – The Need for a Collective Response", organised by the International Water Management Institute (IWMI), in the latter half of May in Pakistan’s hilly tract of Bhurban.
Fears of water scarcity
“Pakistan will become water scarce by 2025," pointed out Dr Ghulam Rasul, the director general of the, Pakistan Meteorological Department (PMD).
He recommended that, without wasting more time, Pakistan should come up with a water policy, build water storage's and develop a mechanism to regulate and protect groundwater.
In Pakistan water availability per person annually is just 1,017 cubic meters, dangerously close to 1,000 cubic meters, crossing which would mean the country is water scarce.
NASA’s researchers found that of the planet’s 37 largest aquifers studied between 2003 and 2013 the Indus Basin aquifer is the second most over stressed and was being depleted while receiving little to no recharge. It is also on the World Resource Institute‘s water stress index.
In a report – yet to be released – by the Pakistan Council of Research in Water Resources (PCRWR) it is apparently stated that the country touched the "water stress line" in 1990 and crossed the "water scarcity line" in 2005.
But can anything be done to turn the clock back?
"Unfortunately not," said Arif Anwar, who heads the IWMI in Pakistan.
"We have a certain population and our birth rate is changing rapidly.
So the situation is really very desperate and acute".
At present the country’s population is estimated to be around 190 million.

By 2030 it will grow to 244m, and by 2100, Pakistan’s population is projected at 364m, states the World Population Prospects 2015. With a rising population the demand is going to increase. According to a 2015 IMF report the demand for water is on the rise and is projected to reach 274 million acre-feet (MAF) by 2025, while supply is expected to remain stagnant at 191 MAF, resulting in a demand-supply gap of approximately 83 MAF.
At the same time, poor management of existing water resources, compounded by changing precipitation patterns due to global warming has made Pakistan susceptible to extreme floods, long spells of drought and increasing natural disasters. On German watch’s Climate Risk Index, Pakistan is among the ten countries most affected by extreme weather events.
And this despite Pakistan being surrounded by 7,259 glaciers with 2,066 cubic kilometres of ice in the three mountain ranges of the Himalayas, Hindukush and Karakoram spanning 11,780 square kilometres.

It is these glaciers that feed the mighty Indus and its 1.12 million square kilometre basin, 47pc of which is in Pakistan and 39pc, 8pc and 6pc in India, China and Afghanistan respectively. Pakistan’s agriculture accounts for 93pc of water drawn from the Indus.
"Pakistan is heading to the water scarce value because of population increase not necessarily because the volume of water in the country has decreased," said Anwar.
He said that there were other countries in the world that were also water scarce. Giving the example of the Middle East, he said: “But they don’t depend on water as much as we do they depend on oil. So it is a problem for us unless we can either develop our economy away from water, as say the Silicon Valley has done, or start to export people in very, very large numbers!” he quipped.
