As a result, it is seen by farmers as an attractive, reliable, and easily accessible source of water (Garrido and Iglesias, 2006) and is highly popular for this reason (Garduno and Foster, 2010). While agriculture is a significant contributor to the recharge of shallow aquifers, both via surface and groundwater irrigation (Taylor et al., Non-renewable abstraction reached 234 km3/year or 20% of gross irrigation demand in 2000, and had more than tripled since 1960 (Wada et al., Due in part to increased climate variability, which affects access to surface water, groundwater resources are increasingly used to the point of being exploited beyond recharge in multiple agricultural regions (Taylor et al., This situation has made groundwater use "one of the most important challenges for agriculture" (OECD, 1998, 2013e). Continued abstraction results in falling water tables, which in turn increases the cost of pumping and can create a "race to the bottom" among producers.
