Irrigation is most likely necessary for crop growth in the Southwest region of the United States due to its arid and semi-arid climate conditions. This area typically experiences low annual rainfall, high temperatures, and prolonged dry spells, making natural water sources insufficient for sustaining agriculture. As a result, farmers in the Southwest often rely on irrigation systems to provide the necessary water for their crops to thrive, using available resources such as rivers, lakes, or groundwater.

In contrast, regions like New England and the Southeast generally have more abundant rainfall, reducing the necessity for irrigation. Similarly, while the Pacific Northwest has its unique agricultural needs, it benefits from a wetter climate, which tends to support crop growth with less reliance on irrigation systems compared to the Southwest. This combination of factors highlights why irrigation is particularly critical in the Southwest for agricultural success.
