Big Water Crisis in Pakistan

According to reports of World Bank (WB) and Asian Development Bank (ADB), Pakistan is one of the most water-stressed countries in the world; it is likely to face an acute shortage of water in coming five years due to lack of availability of irrigation water, human  and human consumption

This limited commodity has a direct bearing on almost all sectors of the economy. Fortunately, Pakistan is blessed with a number of water resources, with water flowing down the Karakorum and Himalayas, the world’s highest glaciers, a unique and free bounty of nature. Total earth surface area is 29.9% and the rest of area of this planet is filled with water. Unfortunately, water scarcity is still a constraint. Only one percent of total earth water is available for consumption. About 5 billion people on earth are experiencing water scarcity of various extents. In Pakistan, its significance is more than ordinary due to farming nature of the economy. Pakistan has in most areas of agriculture, a monsoon climate and there might be abundant rainfall during the wet season and then a very long dry period.

According to reports of World Bank (WB) and Asian Development Bank (ADB), Pakistan is one of the most water-stressed countries in the world; it is likely to face an acute shortage of water in coming five years due to lack of availability of irrigation water, human  and human consumption. A World Bank (WB) states that water supply has fallen from 5000 cubic meters per capita in 1950 to 1000 cubic meter per capita in 2010 and is likely to further decrease to 800 cubic meters per capita by 2020. Factors contributing in reduction of per capita available water are Skyrocket increase in population, climate change, and lack of solid vision to construct water reservoirs and misplaced use of Chenab and Jhelum by India under the Indus Water Treaty (IWT). One figure states that about 40-55 million Pakistanis have no access to regular drinking water and around 630 Pakistani children die each day due to the waterborne illness of diarrhea.

 According to a report in 2014, 43% of Pakistan’s employment is in the agricultural sector. This prosperous field relies on the single largest contiguous irrigation system in the world. NASA satellite date of world’s underground aquifers divulges rapidly depleting water tables. The aquifer in Indus Basin whose tributaries constitute Pakistan’s chief water source is the second most water-stressed in the world due to rapid depletion or no recharging. It’s not surprising because seven years ago, groundwater tables in different parts of Lahore had fallen up to 65 feet over a five year period.  Unlike other developing countries of the world, where 70 to 80 percent of fresh water resources are utilized for agricultural purposes. Pakistan consumes up to 98 percent of its water resources for agriculture. But this an appalling feat that Pakistan fosters one of the lowest crop yield per unit of water in the world.

The alarming threat of water scarcity is an ignored issue in Pakistan that is rarely talked about in Pakistan’s politics and yet it comprises one of the biggest challenges to Pakistan’s survival with projected population of 263 million in the year 2050 (UNO 2012), Pakistan needs to put some serious thought into how it will meet adequate water needs to be required for agriculture, industry and human consumption in the face of rapidly dwindling reservoirs. The Himalayan glaciers, whose ice melt replenishes the Indus basin annual freshwater, is receding by one meter per year due to global warming. This phenomenon has had an incredible impact on Pakistan’s water availability.

According to World Bank (WB) report of 2006, Pakistan was fast moving from being water-stressed to water-scarce country, primarily because of over-exploitation of ground water resources, deprived condition of water infrastructures and unsustainability of water management system. It is interesting that our country’s large parts have good soil, sunshine and farmers and these can get much more value from existing flows.    

 Pakistan always practices a cycle of Build-Neglect-Rebuild when it comes to its infrastructure. Currently, about one-third of water from irrigation system is lost in delivery due to seepage and malfunctioning watercourses. Still these numbers do not faze government officials in Islamabad, as Pakistan continuous to push for the construction of new dams instead of renovating its decaying system. Another water wastage source comes from farms themselves. About one-quarter of total water delivered for irrigation is wasted from poor management in rural areas; it is due to the warabandi system of water management. According to this, each farmer has a specific day and time to irrigate his field. The quantity of water use is irrelevant as each farmer pays a flat fee. Although this system was intended to be equitable in the face of water shortages, in reality farmer who have first access can take a lion’s share. Since water is not priced on the usage basis, there is no rule to discourage wastage or overuse. Feudalism is also a major source, as large influential farmers use a major portion of water due to their power and it forces poor farmers to rely on tube wells to extract ground water.

The current status quo is characterized by provincial disputes, poor infrastructure, waste, and corruption. The situation in Pakistan seems grim, but there are some steps that can be taken to ensure water security. One proposed solution is repairing and maintaining the existing canal system. This would free about 75 million acre-feet of water, close to 83 million acre feet water shortfall that the IMF projects Pakistan will face in coming years.
