A US geographer is partnering with geoscientists and scientific societies to provide training for those in the Earth, space and environmental sciences in how bystanders can halt sexual harassment. The effort aims to improve gender equity and the work climate in the geosciences by training university administrators and faculty members in how best to address, prevent and eliminate sexual harassment (see go.nature.com/2x3g1db). Project lead Erika Marín-Spiotta, a geographer at the University of Wisconsin–Madison, says that the team will hold workshops at US campuses and for professional societies, including the Society for Advancement of Chicanos/Hispanics and Native Americans and the American Geophysical Union. Intervention training for researchers, which will source input from those who face harassment on the basis of race or gender identity, is necessary, because harassment often happens in the field. The project is funded by a US$1.1-million, 4-year US National Science Foundation grant. “We plan to come up with a model that other disciplines can use, apply or modify as needed,” says Marín-Spiotta.
