What are Irrigation Non-Expansion Areas (INAs)?

Irrigation Non-Expansion Areas (INAs) are specifically designated regions in Arizona that require regulation due to the significant and ongoing depletion of groundwater resources. The establishment of INAs aims to manage and protect water supplies by limiting or controlling the expansion of agricultural activities that would further stress these already depleted water resources. By imposing such regulations, the state seeks to ensure sustainable water use and promote conservation efforts in areas that are experiencing critical levels of groundwater depletion. This designation reflects a proactive approach to address water scarcity concerns while balancing agricultural needs.

In contrast, areas with extreme groundwater depletion would not necessarily have the same designated regulatory framework as INAs, as extreme depletion might indicate a critical situation requiring immediate attention rather than a structured management area. Areas with no regulation on water usage would not be classified as INAs since the core purpose is to implement specific regulations in response to groundwater issues. Lastly, designating areas for agricultural expansion directly contradicts the principles of INAs, which are focused on conservation and regulation, rather than enabling growth of agricultural activities.
