Karez systems, while effective for irrigation and water supply in arid regions, have several disadvantages. They require significant initial investment and maintenance, which can be challenging in remote areas. Additionally, karez systems are vulnerable to sedimentation and can become clogged, reducing efficiency over time. Finally, reliance on karez can lead to over-extraction of groundwater, potentially depleting aquifers and harming the local ecosystem.

What is karez system?
The karez system is an ancient irrigation method used primarily in arid regions, particularly in parts of Iran, Afghanistan, and Central Asia. It consists of a network of underground tunnels that collect and transport groundwater from aquifers to fields and villages. By utilizing gravity, the karez system minimizes water evaporation and maximizes water availability for agriculture and domestic use. This sustainable technique has been crucial for supporting communities in dry environments for centuries.
What is a karez system?
A karez system is an ancient irrigation method used primarily in arid regions, particularly in Iran and parts of Central Asia. It consists of a series of underground tunnels that transport water from aquifers in the mountains to agricultural fields in the valleys. This system helps minimize evaporation and ensures a steady water supply for farming, making it crucial for sustaining agriculture in dry climates. The karez system is a testament to traditional engineering and resource management in water-scarce areas.
