The Stimson Center held an event yesterday called “Water and Peace in Afghanistan and Pakistan,” at which Dr. Daanish Mustafa, a geographer at King's College, London, outlined the intricate linkages between water resources and regional stability. According to Mustafa, who has conducted extensive field research in Baluchistan and southern Afghanistan, traditions surrounding access to water form the glue that has held local communities together for centuries. Recent events, however, have begun to unravel social structures with second and third order effects on security.
At the heart of the matter is the traditional karez (also qanat) irrigation system. The ancient technique involves allowing natural water pressure to pump water horizontally underneath agricultural fields through hand-constructed underground channels. In communities throughout southern Afghanistan and Baluchistan, deeply engrained cultural norms dictate access to water and are enforced by mirabs, or water masters. Revered by their communities, mirabs have customarily ensured equity in water distribution and conscientious maintenance of the system’s entire length. For a karez system to remain viable, all stakeholders must use it responsibly.
The advent of tube-wells has disrupted the traditional order. Tube-wells drill directly down to the water table (sometimes 500 feet or more below the surface), sucking up the available water. Over time, though, they draw the water table down farther and farther, requiring deeper and deeper drilling. Tube-wells, then, have the potential to lower water tables enough so that karez systems are rendered inoperable, affecting
