Photo by Brendan Hoffman hoffmanbrendan / The Indus River and Sukkur Barrage at sunset in Sukkur, southern Pakistan. The Indus is one of Asia's most vital rivers, supplying water to hundreds of millions of people in its watershed in Tibet, Afghanistan, India, and Pakistan. The Sukkur Barrage (backgound) helps control water flow into the world’s largest canal system, snaking thousands of miles through fields of rice, cotton, wheat, and sugarcane, irrigating what would otherwise be a desert, to form the cornerstone of Pakistan’s economy.
