Instead, Kotutwa Johnson, an enrolled member of the Hopi tribe, practices the Hopi tradition he learned from his grandfather on the Little Colorado River Plateau near Kykotsmovi Village in northeastern Arizona, a 90-minute drive from Flagstaff: “In spring, we plant eight to 10 corn kernels and beans per hole, further apart, so the clusters all stand together against the elements and preserve the soil moisture.” For instance, high winds often blow sand across the barren plateau. “This year was a pretty hot and dry year, but still, some of the crops I raised did pretty well,” he says with a satisfied smile. “It’s a good year for squash, melons, and beans. I’ll be able to propagate these.”

Dry farming has been a Hopi tradition for several millennia. Kotutwa Johnson might build some protection for his crops with desert brush or cans to shield them from the wind, but his plants thrive without any fertilizer, pesticides, herbicides, mulch, or irrigation. This is all the more impressive since his area usually gets less than 10 inches of rain per year.

In the era of climate change, the practice of dry farming is met with growing interest from scientists and researchers as farmers grapple with droughts and unpredictable weather patterns. For instance, the Dry Farming Institute in Oregon lists a dozen farms it partners with, growing anything from tomatoes to zucchini. However, Oregon has wet winters, with an annual rainfall of over 30 inches, whereas on the plateau in Arizona, Johnson’s crops get less than a third of that. Farmers in Mexico, the Middle East, Argentina, Southern Russia, and Ukraine all have experimented with dry farming, relying on natural rainfall, though conditions and practices vary in each region.

For Kotutwa Johnson, it’s a matter of faith and experience. Between April and June, he checks the soil moisture to determine which crops to plant and how deep. He uses the traditional wooden Hopi planting stick like his ancestors, because preserving the topsoil by not tilling is part of the practice. “We don’t need moisture meters or anything like that,” he explains. “We plant everything deep—for instance, the corn goes 18 inches deep, depending on where the seeds will find moisture.” His seeds rely on the humidity from the melted winter snow and annual monsoon rains in June.

His harvest looks unique, too. “We know 24 varieties of indigenous corn,” he says, showing off kernels in indigo blue, purple red, snow white, and yellow. His various kinds of lima and pinto beans shimmer in white, brown, merlot red, and mustard yellow. Studies have shown that indigenous maize is more nutritious, richer in protein and minerals than conventional corn, and he hopes to confirm similar results with his own crops in his role as professor at the School of Natural Resources and the Environment at the University of Arizona, and as a core faculty member with the fledgling Indigenous Resilience Center, which focuses on researching resilient solutions for Indigenous water, food, and energy independence. He earned a PhD in natural resources, concentrating on Indigenous agricultural resilience, not least to “have a seat at the table and level the playing field, so mainstream stakeholders can really hear me,” he says. “I’m not here to be the token Native; I’m here to help.” For instance, he attended COP 28, the 2023 United Nations climate change conference in Dubai, to share his knowledge about “the reciprocal relationship with our environment.”

Kotutwa Johnson was born in Germany because his dad was in the military, but he spent the summers with his grandfather planting corn, squash, beans, and melons the Indigenous way in the same fields he’s farming now, where he eventually built an off-grid stone house with his own hands. “As a kid, I hated farming because it’s hard work,” he admits with disarming honesty, followed by a quick laugh. “But later I saw the wisdom in it. We’ve done this for well over 2,000 or 3,000 years. I’m a 250th-generation Hopi farmer.”
