The conflict led to the deaths of between 562,000[51] and 2,000,000 Afghans, while millions more fled from the country as refugees;[58][59][52][53] most externally displaced Afghans sought refuge in Pakistan and in Iran. Approximately 6.5% to 11.5% of Afghanistan's erstwhile population of 13.5 million people (per the 1979 census) is estimated to have been killed over the course of the conflict.
Irrigation systems, crucial to agriculture in Afghanistan's arid climate, were destroyed by aerial bombing and strafing by Soviet or government forces. In the worst year of the war, 1985, well over half of all the farmers who remained in Afghanistan had their fields bombed, and over one quarter had their irrigation systems destroyed and their livestock shot by Soviet or government troops, according to a survey conducted by Swedish relief experts.[275] Everything was the target in the country, from cities, villages, up to schools, hospitals, roads, bridges, factories and orchards. Soviet tactics included targeting areas which showed support for the Mujahideen, and forcing the populace to flee the rural territories the communists were unable to control. Half of Afghanistan's 24,000 villages were destroyed by the end of the war
