The Helmand-Arghandab Valley irrigation system in southern Afghanistan is one of the country’s most important capital resources. Prior to the civil and military conflict that has engulfed Afghanistan for more than 15 years, agricultural lands irrigated by the system produced a large proportion of the country’s food grains and cotton. This study successfully employed Landsat satellite imagery, Geographic Information Systems (GIS), Global Positioning Systems (GPS), and field surveys to assess changes that have occurred in this system since 1973 as a consequence of the war. This information is a critical step in irrigation rehabilitation for restoration of Afghanistan’s agricultural productivity.
