Description: Freshwater use has become a major social and environmental concern in the last two decades. This is due to rising food demand, rapid urbanization, industrial development and climate change which are significantly increasing pressure on freshwater resources (Ridoutt and Pfister, 2010, Gheewala et al., 2013). Agriculture is one of the largest users of global freshwater resources, accounting for about 70% of freshwater withdrawals as irrigation (WWAP, 2009). Irrigation accounts for 84% of the total water use in South Saskatchewan River Basin (SSRB) in Alberta (AMEC 2009). Irrigation water use is competing with other demands for freshwater such as household and industrial consumption. A projection of water supply study for the SSRB in Alberta forecasts that water use in the SSRB will increase 53% from the current 1,981,000 dam3 to about 3,040,000 dam3 by 2030 mainly due to expansion of irrigation districts (AMEC 2009). A significant increase in water use will affect a ratio of total fresh water withdrawals to hydrological availability (WTA) leading to a greater water stress index (WSI) in Alberta. The study aims to assess the water footprint of irrigated potato production in Alberta for two scenarios
