He further said: "Anyone can install any number of wells of any capacity, at any depth and can pump any amount of water at any time". There is no regulatory framework to manage groundwater.
Not only has the quantity of groundwater depleted, the water has been contaminated with industrial and municipal effluent. If groundwater in parts of Punjab and Sindh is laced with arsenic, in Balochistan and Khyber Pakhtunkhwa it has fluoride and nitrates.
Transboundary water sharing gets complicated
The situation is no better at the transboundary level. There is no mention of the groundwater distribution in the 1960 transboundary Indus Waters Treaty. When the water distribution treaty was being negotiated, there was little information about the Indus basin’s aquifers but now more than ever experts want the sharing of groundwater to be included.
"There is little research on the characteristics of aquifers underlying the Indus basin. Unless and until there is reliable and shared information about the aquifers, no sound policy or sharing mechanism can be devised and it would be foolish to think that IWT could be amended without the proper research to support an amendment," said Alam, who has studied the treaty at length.
Transboundary mistrust
Limited access to water and climate data in the region, said Mirza Asif Baig, the Indus Water Commissioner, has only exacerbated the cooperative environment required for trans-boundary water dispute resolution between Pakistan and India.
At the moment, said Baig, hydrological data that is important for Pakistan and for which no additional data collection systems are required to be installed, are not being provided by India despite repeated requests from Pakistan.
"There are provisions for bilateral data sharing but these have been made ineffective by legal trickery thus making the Treaty operate in an environment of non-cooperation instead of co-operation".
He, however, made it clear that the flood data that is provided by India is useful for Pakistan but there are other data that are denied that are much required and its supply would definitely improve the working environment of the Permanent Indus Commission.
But this lack of information and data sharing is not only between India and Pakistan but persists within intra government departments.
This lack of information sharing, said Baig, has hampered the various government departments to plan, manage and develop what is essentially a shared river basin with the result it has "adversely affected the efforts being made to protect lives and property of people from vagaries of natural disasters such as floods", he said.
But this lack of information and data sharing is not peculiar to India and Pakistan alone; it even exists between the different government departments within Pakistan who work in silos.
