The Helmand and Arghandab Valley Authority (HAVA) based in Lashkar Gah, Afghanistan, originally named the Helmand Valley Authority (HVA) until its expansion in 1965, was established on December 4, 1952, as an agency of the Afghan Government. The agency was modelled on the Tennessee Valley Authority in the United States, with a remit covering lands in Farah Province, Ghazni Province, Helmand Province, Herat Province, and Kandahar Province. The HAVA is overseen by the Afghan Ministry of Agriculture, Irrigation and Livestock (previously the Ministry of Agriculture and Irrigation).
