For instance, it is considered a major and growing issue in Western Galilee in Israel and Laguna Region in Mexico (2014 OECD questionnaire). As a result of sustained groundwater pumping, saturated thicknesses and well yields can be reduced significantly. In some cases, reductions in aquifer viability have been severe enough that there has been a gradual transition from irrigated back to dryland agriculture (e.g. parts of western Kansas in the United States). In other areas, such as north Texas, irrigation is still possible but it is clear that the current intensity (in terms of irrigated area and application rates) cannot be maintained in the future.
