The Helmand River is a significant waterway in southern Afghanistan, flowing approximately 1,150 kilometers (715 miles). It originates in the Hindu Kush mountains and travels through various provinces, including Helmand and Nimroz, before emptying into the Hamun Lake in Iran. The river is crucial for irrigation and agriculture in the arid regions it traverses. The Helmand River basin supports local communities by providing water for farming and livestock. Its waters are vital for crops such as wheat and cotton, which are essential for the economy of the region. However, the river faces challenges, including over-extraction and pollution, impacting its sustainability.
