Karez: Balochistan's Underground Water Commons

01

This is a cultural explainer, not a Balochistan itinerary

The karez system can be studied as water history without recommending travel through Balochistan. On 14 September 2026, the UK FCDO advised against all travel to the entire province; Australian and US advisories also said not to travel there because of severe security and kidnapping risks. The US page placed Balochistan at Level 4, while Pakistan overall remained Level 3 for US citizens.

Readers should follow the advice issued for their nationality and verify Pakistani permission rules. Do not treat an invitation, guide, police escort or project contact as a workaround to a government no-travel warning. The sections below therefore explain shafts, gradients, communal maintenance and heritage value from official documents. They do not form a route, endorse a field visit or imply that any named karez is currently open to foreign visitors.

The machine beneath the landscape

UNESCO's Tentative List description explains the basic sequence: a mother well reaches the aquifer, a gently graded tunnel conveys water, vertical shafts allow spoil removal and maintenance, and the channel eventually emerges at the surface. Gravity supplies the energy. This makes a karez fundamentally different from isolated wells that lift water independently.

The alignment demands knowledge of slope, soil and groundwater. Too steep a tunnel can erode; too shallow or poorly aligned a system may fail to deliver. The chain of shafts seen from above therefore marks repeated access to one underground conduit. Calling every shaft a well obscures the engineering relationship that makes the whole system work.

• Mother well: the upstream point that reaches groundwater.
• Gallery: the sloping underground channel that transports water.
• Vertical shafts: construction, ventilation and maintenance access along the line.
• Daylight point: where flowing water becomes available for distribution.

03

Flow becomes a schedule of rights

The UNESCO account describes water allocation through time-based shares, sometimes expressed as shabanas. That detail reveals the karez as a commons governed through recognised entitlements and routines. The infrastructure produces a continuous flow, but a community must still decide who receives it, when and with what obligations.

A water share is therefore neither a casual favour nor merely a pipe connection. It can carry economic and social meaning across households and fields. Maintenance also depends on coordinated labour and specialised knowledge. When the social agreement weakens, repairing only the tunnel may not restore the system's function. Governance is part of the engineering.

Provincial policy brings the karez into the present

Balochistan Water Policy 2024 calls for community participation in water management and specifically recognises karez shareholders within local governance. It also addresses groundwater monitoring, recharge and critical zones. These are present-tense policy concerns, not museum interpretation: underground water systems compete within a changing extraction and management environment.

The provincial Climate Change Policy 2024 likewise calls for revitalisation and rehabilitation of karez systems alongside sustainable governance and lower-water agricultural choices. Read together, the documents reject a romantic solution in which cleaning a tunnel fixes everything. Hydrology, land use, monitoring, institutions and long-term maintenance must align.

• Rehabilitation must consider the water source, not only visible damage.
• Shareholders and water users need a place in decisions.
• Groundwater monitoring matters because nearby extraction can affect shared systems.
• Agricultural demand belongs in the same conversation as heritage protection.

Tentative List status needs careful language

Pakistan submitted the Karez System Cultural Landscape to UNESCO's Tentative List in 2016. A Tentative List identifies property a state may consider nominating; it is not World Heritage inscription. Articles, tour descriptions and captions should not call Balochistan's karez systems UNESCO World Heritage sites.

The UNESCO entry is still valuable because it records the relationship among technology, water rights, settlement and landscape. Some numerical inventory statements on that page date from the 2012 material cited in the nomination. They should not be repeated as current counts in 2026 without a newer official survey. The durable facts are the operating principles and cultural relationships, not a stale total.

06

Maintenance is skilled and collective

An underground channel can accumulate sediment, collapse or lose flow, and its shafts create hazards for anyone unfamiliar with the site. Maintenance is consequently not a tourist activity or a suitable do-it-yourself conservation project. It requires people who understand the alignment, ground conditions, ventilation and local rules.

Balochistan's Irrigation Department defines its role around management and conservation of surface and groundwater resources and the rehabilitation of irrigation infrastructure. That institutional frame reinforces an essential point: karez stewardship sits within broader water administration. Visitors and writers should seek authorised, community-led interpretation and should never enter shafts or tunnels without formal arrangements.

• Observe openings from a safe distance because edges may be unstable.
• Do not block, divert or contaminate flowing water.
• Do not disclose precise locations of vulnerable features without community consent.

07

Report a living system without turning it into folklore

Good reporting asks who manages the system now, how shares are defined, which maintenance practices continue and what pressures users identify. It distinguishes an operating karez from an abandoned one and a restored channel from a proposed project. Names and technical terms should follow the community's usage rather than imposing a generic label.

Avoid invented interviews and claims that one technology can solve provincial water scarcity. Official policies place karez rehabilitation among many measures, including monitoring, recharge, regulation and changes in water demand. The system matters precisely because it shows how technology and collective rules work together, not because it offers a simple universal cure.

08

What gravity teaches about stewardship

A karez moves water without continuously adding mechanical energy, yet that apparent simplicity rests on demanding knowledge and cooperation. The tunnel must follow a workable gradient; access shafts must be maintained; shares must be honoured; the aquifer must not be treated as limitless. Low-energy delivery does not mean maintenance-free water.

That is why karez heritage belongs in a Pakistan destination publication even when readers never enter a tunnel. It provides a way to understand Balochistan through adaptation, commons governance and landscape knowledge rather than scenery alone. The most respectful encounter may be a community-approved explanation from the surface, followed by support for the people doing the continuing work.
