Résumé
Wind erosion and dust emissions from global drylands impact ecosystem health, agricultural production and food security, human health and climate. Despite extensive study of how wind erosion and dust emission occur, and how they affect Earth’s atmosphere and human populations, little is known about where, when, and why the processes take place across different ecosystems, or how changes to Earth’s ecosystems influence their rates at different locations over time. Understanding these interactions is important for land managers to identify where wind erosion and blowing dust may be a problem and act to sustainably manage agriculture and ecosystems over the long term. This research will examine how different types of ecosystem change occurring across North America due to human disturbances, drought, fire and invasive plant species impact rates of wind erosion and dust emission. The research will promote international collaboration among researchers in the United States and United Kingdom as part of a NSF/GEO-UK NERC project. It will produce new information that supports management of North American drylands and will generate educational materials for K-12 students and provide scientific training to underrepresented undergraduate and graduate students.
