Agroecosystem Research in the Desert

At the intersection of agricultural production and holistic ecosystem science.

Arizona, the climate of tomorrow - today.

Hotter temperatures and drought are rapidly reshaping the world we live in and directly threaten the food systems we rely on. Currently, arid lands represent 41% of Earth’s land surface, are home to 30% of the global population and produce over 60% of the world’s food.

Harnessing Arizona's expertise

At CALES Center for Agroecosystem Research in the Desert (ARID), we are on a mission to transform the future of arid land agriculture. Agroecosystems, where nature and agriculture converge, are dynamic systems that blend biodiversity, energy flows, and human innovation. At the ARID Center, we’re pioneering solutions that optimize these intricate systems, ensuring that even the harshest deserts can nourish generations to come.

Arizona is developing sustainable strategies to ensure that we can continue to grow the food we need, even as conditions change. The efforts here are helping to shape how we can all adapt to a future where water scarcity and more extreme weather may become the norm. By studying the challenges of today’s environment, we’re creating sustainable agricultural solutions for tomorrow, ensuring a resilient food supply in a changing world.

Current Projects

A petri dish with microbes

Lettuce Microbiome

This project explores how the hidden world of lettuce-associated microbes shapes plant health, nutrition, and resilience in desert agriculture. By revealing the “good microbes” that naturally enhance flavor, nutrition, and durability, the team aims to transform our understanding of what makes lettuce thrive. The work will open new frontiers for sustainable farming, turning microbiome discoveries into biological tools that boost crop performance and food quality.

Tepary Bean

This project uncovers how tepary bean—a native desert legume renowned for its natural heat and drought tolerance—thrives where most crops fail. By revealing how its roots, microbes, and soil environment work together to boost resilience and nutrition, the team aims to unlock the secrets of stress-tolerant agriculture. The findings will guide the design of future crops and farming systems capable of flourishing in a hotter, drier world.
a field of sorghum

Sorghum

This project, In Silico Soils, pioneers a new frontier in understanding how sorghum plants shape and are shaped by their underground microbiomes to thrive in desert agriculture. By linking genetic variation, soil microbial dynamics, and ecosystem modeling, the team will reveal how roots and microbes cooperate to improve soil health, nutrient use, and drought resilience. The insights will feed into next-generation climate models, enabling scientists to predict and design crops that sustain productivity under future heat and water stress.
