Groundwater has been discussed in the context of pricing and financing (OECD, 2009a and 2009b), energy (OECD, 2012b), risk management (OECD, 2013e), and broader perspectives covering climate change (OECD, 2013d and 2014a). Groundwater is also featured in the reviews of water reforms at the country level (e.g. Fuentes, 2011; OECD, 2013b). All these reports include sections, sub-sections, paragraphs, or illustrations that relate to groundwater, but they do not convey policy conclusions specifically geared towards the managers of specific types of groundwater, especially in the context of agriculture. First, a consistent observation is that groundwater is generally under-studied and there is a need for more in-depth assessment of groundwater stocks, use, and management practices.
