My housemate's family grows wild rice in California. But, some land is now too dry. So, he is thinking of putting up solar panels. Other farmers are experimenting with grazing animals like sheep. Intensive grazing (as per Allan Savory) may prevent, or even reverse, desertification. The shade helps mitigate the intense noonday sun in a warming climate.
