Viability of karezes (ancient water supply systems in Afghanistan) in a changing world


An assessment of a six-district region within Kandahar Province where karezes are the most likely source of water indicates that water demand could havecaused water tables to decline by 0.8–5.6 m, more than enough to cause karezes to stop flowing. These results suggest that kariz water production is not sustainable under current climate- and population-growth trends.
