If water supplies are dwindling, should cities or farmers get more of the water? One writer suggests Arizona has made a clear choice for cities:
The shift away from irrigated agriculture in Arizona hasn’t come without a fight. By some measures, farmers are still winning. According to the Arizona Department of Water Resources, more than two-thirds of Arizona’s water is still used to irrigate fields, down from a peak of 90 percent last century.
Decades ago, state officials in Arizona begin to plan for a future without water—and that meant sacrificing agriculture for future urban growth. A massive civil engineering project in the 1960s diverted part of the Colorado River to feed Phoenix and Tucson. Those cities could not exist in their current state without this unnatural influx of Rocky Mountain snowmelt. Now there’s tension across the region, as the realities of climate change and extreme weather catch up with the business-as-usual agricultural bedrock that laid the foundation for the economy here.
Hopefully, future dispatches in this series about water and drought in the Southwest will begin to address the normative questions: what is the proper ratio of water for cities and farmers? Is it necessarily bad if farmers can’t produce as much in Arizona and California (could more be produced elsewhere, do farmers need to shift to new crops, etc.)? Both farming and urban growth have changed the natural water patterns in the region but does one have a stronger claim to the water in the long run?
