N1 - Funding Information:
We wish to thank our many Indigenous collaborators on dietary studies over the last four decades, most recently Luis Eduardo Molina of the Comcaac community of Sonora, who assisted GN with establishing baselines for monitoring dietary changes and advancing food sovereignty through time in two Indigenous villages, and the families from Zapotitlán, Jalisco, who shared their deep knowledge of their ancestral foodways with PC-G and DZ-V. We also wish to acknowledge our collaborators from many cultures including A. Mellado, E. Barnett, M. L. Astorga, M. Estrella Astorga, D. Lewis, J. Ascencio, F. Kabotie, H. Dukepoo, L. Noriega, J. Martínez-Castillo, O. Vargas-Ponce, G. Carrillo-Galván, A. Flores-Silva, I. Torres-García, A. Casas, C.J. Figueredo, S. Rangel-Landa, A. Delgado, D. Cabrera-Toledo; X. Aguirre-Dugua, L. Eguiarte, R. Bye, E. Linares, D, A. Mellado, E. Barnett, R. Felger, C. Marlett, E. Ezcurra, E. Riordan, A. Búrquez-Montijo, L. Smith Monti, E. Riordan, B. Wilder, J. Mabry, C. Khoury, T. Crews, and J. Aronson. Barbara Kuhns graciously assisted with edits of the near-final draft. GN acknowledges long-term funding from the W.K. Kellogg Foundation, and initial funding many decades ago on three grants from the National Science Foundation. GN acknowledges the W.K. Kellogg Foundation Endowment for his position at the Southwest Center which covered page charges as well as travel to Arizona for PC-GM and DZ-V, and to Yucatán for GN.

N2 - Climate change is aggravating agricultural crop failures, and the paucity of wild food harvests for Indigenous desert dwellers in Mexico and the U.S. This food production crisis challenges ongoing efforts by Indigenous communities in obtaining greater food security, prompting them to reconsider the value of traditional Indigenous food systems in both Mesoamerica and Arid America, two adjacent centers of crop diversity. While food production strategies in these two centers share many features, the food plant diversity in the Western Mesoamerican region appears to be greater. However, a higher percentage of plants in Arid America have adapted to water scarcity, heat, and damaging radiation. The phytochemical and physiological adaptations of the food plants to abiotic stresses in arid environments offer a modicum of resilience in the face of aggravated climate uncertainties. By comparing food plant genera comprising Western Mesoamerican and Arid American diets, we detected a higher ratio of CAM succulents in the wild and domesticated food plant species in the Arid American food system. We conclude that food plant diversity in the ancestral diets of both centers can provide much of the resilience needed to advance Indigenous food sovereignty and assure food security as climate change advances.
