What a Geographer Sees highlights a concept or phenomenon that would stand out to geographers. Photos and ﬁgures are used to improve students’ understanding of the usefulness of a geographic perspective and to enable students to apply their observational skills to answer questions.

WHAT A GEOGRAPHER SEES Qanats
anats, also called karez, khettaras, or foggaras, have been used to manage water in about 50 countries or territories worldwide. They are usually constructed near the base of hills or in stream valleys. Water ﬂows through a qanat entirely by gravity.
a. Global distribution of extant or historical Qanats Most of the qanats in use today are in the Middle East. (Source: Data from Salih, 2006; and Dale Lightfoot, personal communication, 2009.)
c. From the air, qanats dot the landscape The openings of the qanat shafts, important for ventilation and access to the tunnel during construction and cleaning of the qanat, create distinctive cultural landscapes. These qanats are in western China.

d. Diminishing lifeline The Kunaﬂusa qanat in northern Iraq still provides water to the villagers, though the ﬂow of water has diminished considerably. This change is mainly the result of other water withdrawals for agriculture from the same underground water source that feeds this qanat and of drought.

b. A cross section showing the different parts of a qanat The photo shows a qanat channel in northern Iraq. Men are usually tasked with clearing the tunnel of vegetation and silt so that the water ﬂow is not impeded.

Think Critically 1. What social, political, or other factors might contribute to qanat abandonment? 2. What is a problem with using a modern political map (as in a.) to indicate the location of qanats?
In each chapter, the Video Explorations feature, researched by Joy Adams of Humboldt State University, showcases one of more than 30 National Geographic videos from the award-winning NGS collection. The videos are linked to the text and provide visual context for key concepts, ideas, and terms addressed in the chapter.
