Because of prolonged drought, increased atmospheric warming, and reduced water resources available for irrigation, farmers are facing difficult decisions. Do they allow their lands to go fallow, give up their lands so that they can be utilized to support photovoltaic renewable energy production, or do they transition to more drought-adapted crops? Here we explore the potential for combining both PV installations and drought-adapted crops, allowing for an agrivoltaic approach for drylands. We planted multiple varieties of prickly pear cactus (grown for their edible pads and fruits), agaves (harvested at maturity for syrup and alcohol production), indigenous beans, and drought-adapted sorghum in control full-sun and agrivoltaic settings. We tracked crop survival and growth throughout the summer monsoon for all crops. These measurements are still being conducted, but cumulative data for all crops and treatments will be completed by October.
