Researchers propose climate-smart desert food production model for land and human health

Titre : Researchers propose climate-smart desert food production model for land and human health

As the National Weather Service warns that a heat wave spreading across the southwestern United States is of a "magnitude rare, dangerous and deadly," a team of scientists, led by the University of Arizona, has generated a new vision aimed at reducing climate disruptions to food security, human health and rural economies.

Présentation
The researchers propose restructuring desert food production from the ground up, by selecting wild food crops already adapted to extreme conditions. The desert food crops would be companion-planted or "intercropped" in designs that not only reduce heat stress in the plants, but among the farmworkers who care for them as well.

The researchers’ article, titled "An Aridamerican model for agriculture in a hotter, water scarce world," calls for a dramatic paradigm shift to move desert food production away from water-consumptive, heat-intolerant annual crop plants.

Conventional agriculture attempts to reshape land and water resources to protect single crops grown in uniform stands from heat and drought stress—a strategy that is becoming increasingly costly and unsustainable under rapidly changing climate and soil conditions, the researchers say. Instead, they suggest that farmers in arid landscapes select crops from wild, resilient native species already adapted to aridity
