ABSTRACT
Developing efficient productive agriculture, while preserving groundwater quality, is one of the most important challenges in water resource sustainability. On the one hand, developing agriculture is straightforward wherever agricultural input, such as water and nutrients, is unlimited. On the other hand, productive agriculture must inherently include the leaching of excess lower quality water below the root zone to the unsaturated zone and ultimately to the groundwater (Shani et al., 2007; Dudley et al., 2008). As such, maintaining the delicate balance between productive agriculture and groundwater quality requires a broad perspective over different time and dimensional scales. While agricultural productivity is measured on a timescale of seasons (several months to several years), its final impact on
groundwater is a long-term cumulative process with a timescale of years to decades.
