Farming, construction and similar land-altering human activity disturbs the native layer of biocrust on the surface of Arizona’s desert soil. Once that biocrust is gone, conditions are ripe for the intense dust storms that afflict large areas throughout much of the state. It can require decades for the biocrust to grow back sufficiently to prevent those storms. ASU researchers are working on ways to help remedy the problem through devising methods to suppress airborne dust. The research team includes faculty members Emmanuel Salifu, Edward Kavazanjian and Matthew Fraser in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools. Salifu and Fraser are featured in a video about the project.
