The Indus is one of Asia’s mightiest rivers. From its source in the northwestern foothills of the Himalayas, it flows through the Indian state of Jammu & Kashmir and along the length of Pakistan to the Arabian Sea. The river and its five tributaries together make up the Indus Basin, which spans four countries and supports 215m people.
Yet fast-growing populations and increasing demand for hydropower and irrigation in each country means the Indus is coming under intense pressure.
