Phoenix the city is limited by its existing water rights but the geographical area isn't really that constrained; water rights are just held by private parties, particulaly farmers. ~70% of all water used in the state is used in agriculture. Industrial and residential consumers simply have to purchase those rights if they want to continue to expand in the area and chip making is a high value add industry.
Before Phoenix the city was founded, there was a canal built by the indigenous people who live there in the lower Sonoran.
That canal became the basis for Phoenix, and eventually, the big canal that transport water long range through the state.
The other is that, with sufficient water, you can grow year round.
Not that I think industrial ag is good for society.
Phoenix itself is a metro area whose primary economic driver is real estate speculation. Many older citrus orchards has been surrounded, and sometimes bought and redeveloped.
It's sunny for a lot of the year. Ex. you can get an extra harvest of alfalfa per year compared to other climates.
Farming isn't really that large of an industry in Arizona today, maybe 2% of GDP tops. But my understanding is that surface water rights were allocated over a hundred years ago and naturally those rights were allocated to the people that wanted them then, i.e. agricultural landowners.

California is a desert too.
Agriculture is an industry. Of course it is. It employs people, it makes use of technology, it is a distinct sector of the economy.
Industry refers to a particular way of doing things that involves portable use of power. Instead of relying on natural cycles (wind-, water-driven machinery), it involves the use of engines (steam, gasoline, electrical) to drive tractors, pumps, produce industrial-scale fertilizers, etc. These engines can be constructed where there are lack of natural resources, or made portable, thus decoupling them from locations of natural resources. That decoupling is what allows industrialized systems, including industrial agriculture, to scale.
Agriculture is largely practiced with industrial methods now, but it's been around a lot longer before proto-industrial methods (water and wind mills). For example, Egypt, as a civilization, benefited from the natural flooding and silt of the Nile. It's been the bread basket for empires for several thousand years. They were not using industrial methods two or three thousand years ago.
There are also other forms of agriculture that is not easily recognized by the narrow lens we have today -- such as perennial food forests, hidden in the ruins of Amazonian jungles, or the Pacific Northwest, or the forest that used to cover the lands between the Appalachia and the Mississippi river. Those were not organized with the concept of employment, and it is distinctively low-tech.
>Farming isn't an industry.
It both is and isn't. Have you seen PETA footage from inside factory farms? It's hellish in that special way only the industrial revolution could produce.
I am sure that some people will question some of the historiography there, but Cadillac Desert is a book all about the history of water management of the great plains, from Kansas onwards.
TLDR: America has spent a whole lot of money trying to make land more productive for farming, including land where it probably doesn't make much economic sense once you account for the infrastructure costs.
Is there any historical reason why farming is a big industry in a state associated with deserts? Did manufacturing never take root there until after WW2 when air conditioning became more affordable?
